podman-kube-play(1) General Commands Manual podman-kube-play(1) NAME podman-kube-play - Create containers, pods and volumes based on Kubernetes YAML SYNOPSIS podman kube play [options] file.yml|-|https://website.io/file.yml DESCRIPTION podman kube play reads in a structured file of Kubernetes YAML. It recre- ates the containers, pods, or volumes described in the YAML. Containers within a pod are then started, and the ID of the new Pod or the name of the new Volume is output. If the YAML file is specified as "-", then podman kube play reads the YAML file from stdin. The input can also be a URL that points to a YAML file such as https://podman.io/demo.yml. podman kube play reads the YAML from the URL and create pods and containers from it. Using the --down command line option, it is also capable of tearing down the pods created by a previous run of podman kube play. Using the --replace command line option, it tears down the pods(if any) created by a previous run of podman kube play and recreate the pods with the Kubernetes YAML file. Ideally the input file is created by the Podman command (see podman-kube- generate(1)). This guarantees a smooth import and expected results. Currently, the supported Kubernetes kinds are: * Pod * Deployment * PersistentVolumeClaim * ConfigMap * Secret * DaemonSet * Job Kubernetes Pods or Deployments Only five volume types are supported by kube play, the hostPath, emptyDir, configMap, persistentVolumeClaim, and image volume types. * When using the hostPath volume type, only the default (empty), Directo- ryOrCreate, Directory, FileOrCreate, File, Socket, CharDevice and Block- Device subtypes are supported. Podman interprets the value of hostPath path as a file path when it contains at least one forward slash, other- wise Podman treats the value as the name of a named volume. * When using a persistentVolumeClaim, the value for claimName is the name for the Podman named volume. * When using an emptyDir volume, Podman creates an anonymous volume that is attached the containers running inside the pod and is deleted once the pod is removed. * When using an configMap volume, Podman creates an anonymous volume that is attached the containers running inside the pod and is deleted once the pod is removed. * When using an image volume, Podman creates a read-only image volume with an empty subpath (the whole image is mounted). The image must already ex- ist locally. It is supported in rootful mode only. Note: The default restart policy for containers is always. You can change the default by setting the restartPolicy field in the spec. Note: When playing a kube YAML with init containers, the init container is created with init type value once. To change the default type, use the io.podman.annotations.init.container.type annotation to set the type to al- ways. Note: hostPath volume types created by kube play is given an SELinux shared label (z), bind mounts are not relabeled (use chcon -t container_file_t -R <directory>). Note: To set userns of a pod, use the io.podman.annotations.userns annota- tion in the pod/deployment definition. For example, io.podman.annota- tions.userns=keep-id annotation tells Podman to create a user namespace where the current rootless user's UID:GID are mapped to the same values in the container. This can be overridden with the --userns flag. Note: Use the io.podman.annotations.volumes-from annotation to bind mount volumes of one container to another. You can mount volumes from multiple source containers to a target container. The source containers that belong to the same pod must be defined before the source container in the kube YAML. The annotation format is io.podman.annotations.volumes-from/target- Container: "sourceContainer1:mountOpts1;sourceContainer2:mountOpts2". Note: If the :latest tag is used, Podman attempts to pull the image from a registry. If the image was built locally with Podman or Buildah, it has lo- calhost as the domain, in that case, Podman uses the image from the local store even if it has the :latest tag. Note: The command podman play kube is an alias of podman kube play, and performs the same function. Note: The command podman kube down can be used to stop and remove pods or containers based on the same Kubernetes YAML used by podman kube play to create them. Note: To customize the name of the infra container created during podman kube play, use the io.podman.annotations.infra.name annotation in the pod definition. This annotation is automatically set when generating a kube yaml from a pod that was created with the --infra-name flag set. Note: Use the io.podman.annotations.pids-limit/$ctrname annotation to con- figure the pod's pids limit. Note: Use the io.podman.annotations.cpuset/$ctrname annotation to restrict a container's execution to a specific set of CPU cores. This is equivalent to the --cpuset-cpus=number option in podman-run(1). Note: Use the io.podman.annotations.memory-nodes/$ctrname annotation to re- strict a container's memory allocations to a specific set of memory nodes on NUMA systems. This is equivalent to the --cpuset-mems=nodes option in podman-run(1). Kubernetes PersistentVolumeClaims A Kubernetes PersistentVolumeClaim represents a Podman named volume. Only the PersistentVolumeClaim name is required by Podman to create a volume. Kubernetes annotations can be used to make use of the available options for Podman volumes. * volume.podman.io/driver * volume.podman.io/device * volume.podman.io/type * volume.podman.io/uid * volume.podman.io/gid * volume.podman.io/mount-options * volume.podman.io/import-source * volume.podman.io/image Use volume.podman.io/import-source to import the contents of the tarball (.tar, .tar.gz, .tgz, .bzip, .tar.xz, .txz, .tar.zst) specified in the an- notation's value into the created Podman volume Kube play is capable of building images on the fly given the correct direc- tory layout and Containerfiles. This option is not available for remote clients, including Mac and Windows (excluding WSL2) machines, yet. Consider the following excerpt from a YAML file: apiVersion: v1 kind: Pod metadata: ... spec: containers: - name: container image: foobar ... If there is a directory named foobar in the current working directory with a file named Containerfile or Dockerfile, Podman kube play builds that im- age and name it foobar. An example directory structure for this example looks like: |- mykubefiles |- myplayfile.yaml |- foobar |- Containerfile The build considers foobar to be the context directory for the build. If there is an image in local storage called foobar, the image is not built unless the --build flag is used. Use --build=false to completely disable builds. Kube play supports CDI (Container Device Interface) device selectors to share host devices (e.g. GPUs) with containers. The configuration format follows Kubernetes extended resource management: apiVersion: v1 kind: Pod spec: containers: - name: container resources: limits: nvidia.com/gpu=all: 1 To enable sharing host devices, analogous to using the --device flag Podman kube supports a custom CDI selector: podman.io/device=<host device path>. Kubernetes ConfigMap Kubernetes ConfigMap can be referred as a source of environment variables or volumes in Pods or Deployments. ConfigMaps aren't a standalone object in Podman; instead, when a container uses a ConfigMap, Podman creates envi- ronment variables or volumes as needed. For example, the following YAML document defines a ConfigMap and then uses it in a Pod: apiVersion: v1 kind: ConfigMap metadata: name: foo data: FOO: bar --- apiVersion: v1 kind: Pod metadata: name: foobar spec: containers: - name: container-1 image: foobar envFrom: - configMapRef: name: foo optional: false and as a result environment variable FOO is set to bar for container con- tainer-1. Kubernetes Secret Kubernetes Secret represents a Podman named secret. The Kubernetes Secret is saved as a whole and may be referred to as a source of environment vari- ables or volumes in Pods or Deployments. For example, the following YAML document defines a Secret and then uses it in a Pod: kind: Secret apiVersion: v1 metadata: name: foo data: foo: YmFy # base64 for bar --- apiVersion: v1 kind: Pod metadata: name: foobar spec: containers: - name: container-1 image: foobar env: - name: FOO valueFrom: secretKeyRef: name: foo key: foo and as a result environment variable FOO is set to bar for container con- tainer-1. Automounting Volumes (deprecated) Note: The automounting annotation is deprecated. Kubernetes has native sup- port for image volumes and that should be used rather than this podman-spe- cific annotation. An image can be automatically mounted into a container if the annotation io.podman.annotations.kube.image.automount/$ctrname is given. The following rules apply: * The image must already exist locally. * The image must have at least 1 volume directive. * The path given by the volume directive will be mounted from the image into the container. For example, an image with a volume at /test/test_dir will have /test/test_dir in the image mounted to /test/test_dir in the container. * Multiple images can be specified. If multiple images have a volume at a specific path, the last image specified trumps. * The images are always mounted read-only. * Images to mount are defined in the annotation "io.podman.annota- tions.kube.image.automount/$ctrname" as a semicolon-separated list. They are mounted into a single container in the pod, not the whole pod. The annotation can be specified for additional containers if additional mounts are required. OPTIONS --annotation=key=value Add an annotation to the container or pod. This option can be set multiple times. Note: For podman kube play, the --annotation flag adds Podman-specific an- notations to the containers and pods created by Podman, not to the Kuber- netes YAML itself. These annotations can be used to configure Podman-spe- cific features like user namespaces (io.podman.annotations.userns), vol- umes-from (io.podman.annotations.volumes-from), and other container behav- iors. --authfile=path Path of the authentication file. Default is ${XDG_RUNTIME_DIR}/contain- ers/auth.json on Linux, and $HOME/.config/containers/auth.json on Win- dows/macOS. The file is created by podman login. If the authorization state is not found there, $HOME/.docker/config.json is checked, which is set using docker login. Note: There is also the option to override the default path of the authen- tication file by setting the REGISTRY_AUTH_FILE environment variable. This can be done with export REGISTRY_AUTH_FILE=path. --build Build images even if they are found in the local storage. Use --build=false to completely disable builds. (This option is not available with the remote Podman client) Note: You can also override the default isolation type by setting the BUILDAH_ISOLATION environment variable. export BUILDAH_ISOLATION=oci. See podman-build.1.md for more information. --cert-dir=path Use certificates at path (*.crt, *.cert, *.key) to connect to the registry. (Default: /etc/containers/certs.d) For details, see containers-certs.d(5). (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines) --configmap=path Use Kubernetes configmap YAML at path to provide a source for environment variable values within the containers of the pod. (This option is not available with the remote Podman client) Note: The --configmap option can be used multiple times or a comma-sepa- rated list of paths can be used to pass multiple Kubernetes configmap YAMLs. The YAML file may be in a multi-doc YAML format. But, it must con- tainer only configmaps --context-dir=path Use path as the build context directory for each image. Requires --build option be true. (This option is not available with the remote Podman client) --creds=[username[:password]] The [username[:password]] to use to authenticate with the registry, if re- quired. If one or both values are not supplied, a command line prompt ap- pears and the value can be entered. The password is entered without echo. Note that the specified credentials are only used to authenticate against target registries. They are not used for mirrors or when the registry gets rewritten (see containers-registries.conf(5)); to authenticate against those consider using a containers-auth.json(5) file. --force Tear down the volumes linked to the PersistentVolumeClaims as part of --down --help, -h Print usage statement --ip=IP address Assign a static ip address to the pod. This option can be specified several times when kube play creates more than one pod. Note: When joining multi- ple networks use the --network name:ip=<ip> syntax. --log-driver=driver Set logging driver for all created containers. --log-opt=name=value Logging driver specific options. Set custom logging configuration. The following *name*s are supported: path: specify a path to the log file (e.g. --log-opt path=/var/log/container/mycontainer.json); max-size: specify a max size of the log file (e.g. --log-opt max-size=10mb); tag: specify a custom log tag for the container (e.g. --log-opt tag="{{.ImageName}}". It supports the same keys as podman inspect --format. This option is currently supported only by the journald log driver. --mac-address=MAC address Assign a static mac address to the pod. This option can be specified sev- eral times when kube play creates more than one pod. Note: When joining multiple networks use the --network name:mac=<mac> syntax. --network=mode, --net Set the network mode for the pod. Valid mode values are: * bridge[:OPTIONS,...]: Create a network stack on the default bridge. This is the default for rootful containers. It is possible to specify these additional options: * alias=name: Add network-scoped alias for the container. * ip=IPv4: Specify a static IPv4 address for this container. * ip6=IPv6: Specify a static IPv6 address for this container. * mac=MAC: Specify a static MAC address for this container. * interface_name=name: Specify a name for the created network interface inside the container. * host_interface_name=name: Specify a name for the created network inter- face outside the container. Any other options will be passed through to netavark without validation. This can be useful to pass arguments to netavark plugins. For example, to set a static ipv4 address and a static mac address, use --network bridge:ip=10.88.0.10,mac=44:33:22:11:00:99. * <network name or ID>[:OPTIONS,...]: Connect to a user-defined network; this is the network name or ID from a network created by podman network create. It is possible to specify the same options described under the bridge mode above. Use the --network option multiple times to specify ad- ditional networks. For backwards compatibility it is also possible to specify comma-sepa- rated networks on the first --network argument, however this prevents you from using the options described under the bridge section above. * none: Create a network namespace for the container but do not configure network interfaces for it, thus the container has no network connectiv- ity. * container:id: Reuse another container's network stack. * host: Use the host's network namespace for the container instead of cre- ating an isolated namespace. Warning: This gives the container full ac- cess to abstract Unix domain sockets and to TCP/UDP sockets bound to lo- calhost. Since these mechanisms are often used to prevent access to sen- sitive system services, isolating them from access by external entities, use of this option may be considered a security vulnerability. * ns:path: Path to a network namespace to join. * private: Create a new namespace for the container. This uses the bridge mode for rootful containers and slirp4netns for rootless ones. * slirp4netns[:OPTIONS,...]: use slirp4netns(1) to create a user network stack. It is possible to specify these additional options, they can also be set with network_cmd_options in containers.conf: * allow_host_loopback=true|false: Allow slirp4netns to reach the host loopback IP (default is 10.0.2.2 or the second IP from slirp4netns cidr subnet when changed, see the cidr option below). The default is false. * mtu=MTU: Specify the MTU to use for this network. (Default is 65520). * cidr=CIDR: Specify ip range to use for this network. (Default is 10.0.2.0/24). * enable_ipv6=true|false: Enable IPv6. Default is true. (Required for outbound_addr6). * outbound_addr=INTERFACE: Specify the outbound interface slirp binds to (ipv4 traffic only). * outbound_addr=IPv4: Specify the outbound ipv4 address slirp binds to. * outbound_addr6=INTERFACE: Specify the outbound interface slirp binds to (ipv6 traffic only). * outbound_addr6=IPv6: Specify the outbound ipv6 address slirp binds to. * port_handler=rootlesskit: Use rootlesskit for port forwarding. Default. Note: Rootlesskit changes the source IP address of incoming packets to an IP address in the container network namespace, usually 10.0.2.100. If the application requires the real source IP address, e.g. web server logs, use the slirp4netns port handler. The rootlesskit port handler is also used for rootless containers when connected to user-defined net- works. * port_handler=slirp4netns: Use the slirp4netns port forwarding, it is slower than rootlesskit but preserves the correct source IP address. This port handler cannot be used for user-defined networks. * pasta[:OPTIONS,...]: use pasta(1) to create a user-mode networking stack. This is the default for rootless containers and only supported in root- less mode. By default, IPv4 and IPv6 addresses and routes, as well as the pod inter- face name, are copied from the host. Port forwarding preserves the origi- nal source IP address. Options described in pasta(1) can be specified as comma-separated arguments. In terms of pasta(1) options, --config-net is given by default, in order to configure networking when the container is started, and --no-map-gw is also assumed by default, to avoid direct access from container to host using the gateway address. The latter can be overridden by passing --map- gw in the pasta-specific options (despite not being an actual pasta(1) option). For better integration with DNS handling, --dns-forward 169.254.1.1 is passed, and this address is added to resolv.conf(5) as first resolver. It is possible to pass --dns-forward explicitly in case a different IP ad- dress should be used. To make the host.containers.internal /etc/hosts entry work and allow connections to the host, --map-guest-addr 169.254.1.2 is passed. Again, it can be set explicitly to choose a dif- ferent IP address. Also, -t none and -u none are passed if, respectively, no TCP or UDP port forwarding from host to container is configured (via Podman's --publish or by passing the pasta -t/-u options directly), to disable automatic port forwarding based on bound ports. Similarly, -T none and -U none are given to disable the same functionality from container to host. All options can also be set in containers.conf(5); see the pasta_options key under the network section in that file. Some examples: * pasta:--map-gw: Allow the container to directly reach the host using the gateway address. * pasta:--mtu,1500: Specify a 1500 bytes MTU for the tap interface in the container. * pasta:--ipv4-only,-a,10.0.2.0,-n,24,-g,10.0.2.2,--dns-for- ward,10.0.2.3,-m,1500,--no-ndp,--no-dhcpv6,--no-dhcp, equivalent to de- fault slirp4netns(1) options: disable IPv6, assign 10.0.2.0/24 to the tap0 interface in the container, with gateway 10.0.2.3, enable DNS for- warder reachable at 10.0.2.3, set MTU to 1500 bytes, disable NDP, DHCPv6 and DHCP support. * pasta:-I,tap0,--ipv4-only,-a,10.0.2.0,-n,24,-g,10.0.2.2,--dns-for- ward,10.0.2.3,--no-ndp,--no-dhcpv6,--no-dhcp, equivalent to default slirp4netns(1) options with Podman overrides: same as above, but leave the MTU to 65520 bytes * pasta:-t,auto,-u,auto,-T,auto,-U,auto: enable automatic port forwarding based on observed bound ports from both host and container sides * pasta:-T,5201: enable forwarding of TCP port 5201 from container to host, using the loopback interface instead of the tap interface for im- proved performance When no network option is specified and host network mode is not configured in the YAML file, a new network stack is created and pods are attached to it making possible pod to pod communication. --no-hostname Do not create the /etc/hostname file in the containers. By default, Podman manages the /etc/hostname file, adding the container's own hostname. When the --no-hostname option is set, the image's /etc/host- name will be preserved unmodified if it exists. --no-hosts Do not modify the /etc/hosts file in the pod. Podman assumes control over the pod's /etc/hosts file by default and adds entries for the container's name (see --name option) and hostname (see --hostname option), the internal host.containers.internal and host.docker.internal hosts, as well as any hostname added using the --add- host option. Refer to the --add-host option for details. Passing --no-hosts disables this, so that the image's /etc/hosts file is kept unmodified. The same can be achieved globally by setting no_hosts=true in containers.conf. This option conflicts with host added in the Kubernetes YAML. --no-pod-prefix Do not prefix container name with pod name. --publish=[[ip:][hostPort]:]containerPort[/protocol] Define or override a port definition in the YAML file. The lists of ports in the YAML file and the command line are merged. Match- ing is done by using the containerPort field. If containerPort exists in both the YAML file and the option, the latter takes precedence. --publish-all Setting this option to true will expose all ports to the host, even if only specified via containerPort in the K8 YAML. In terms of which port will be exposed, --publish has higher priority than hostPort, has higher priority than containerPort. If set to false (which is the default), only ports defined via hostPort or --publish are published on the host. --quiet, -q Suppress output information when pulling images --replace Tears down the pods created by a previous run of kube play and recreates the pods. This option is used to keep the existing pods up to date based upon the Kubernetes YAML. --seccomp-profile-root=path Directory path for seccomp profiles (default: "/var/lib/kubelet/seccomp"). (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines) --start Start the pod after creating it, set to false to only create it. --tls-verify Require HTTPS and verify certificates when contacting registries (default: true). If explicitly set to true, TLS verification is used. If set to false, TLS verification is not used. If not specified, TLS verification is used unless the target registry is listed as an insecure registry in con- tainers-registries.conf(5) --userns=mode Set the user namespace mode for the container. If --userns is not set, the default value is determined as follows. - If --pod is set, --userns is ignored and the user namespace of the pod is used. - If the environment variable PODMAN_USERNS is set its value is used. - If userns is specified in containers.conf this value is used. - Otherwise, --userns=host is assumed. --userns="" (i.e., an empty string) is an alias for --userns=host. This option is incompatible with --gidmap, --uidmap, --subuidname and --subgidname. Rootless user --userns=Key mappings: +-------------------------+-----------+----------------------+ | Key | Host User | Container User | +-------------------------+-----------+----------------------+ | auto | $UID | nil (Host User UID | | | | is not mapped into | | | | container.) | +-------------------------+-----------+----------------------+ | host | $UID | 0 (Default User ac- | | | | count mapped to root | | | | user in container.) | +-------------------------+-----------+----------------------+ | keep-id | $UID | $UID (Map user ac- | | | | count to same UID | | | | within container.) | +-------------------------+-----------+----------------------+ | keep-id:uid=200,gid=210 | $UID | 200:210 (Map user | | | | account to specified | | | | UID, GID value | | | | within container.) | +-------------------------+-----------+----------------------+ | nomap | $UID | nil (Host User UID | | | | is not mapped into | | | | container.) | +-------------------------+-----------+----------------------+ Valid mode values are: auto[:OPTIONS,...]: automatically create a unique user namespace. * rootful mode: The --userns=auto flag requires that the user name contain- ers be specified in the /etc/subuid and /etc/subgid files, with an unused range of subordinate user IDs that Podman containers are allowed to allo- cate. Example: containers:2147483647:2147483648. * rootless mode: The users range from the /etc/subuid and /etc/subgid files will be used. Note running a single container without using --userns=auto will use the entire range of UIDs and not allow further subdividing. See subuid(5). Podman allocates unique ranges of UIDs and GIDs from the containers subor- dinate user IDs. The size of the ranges is based on the number of UIDs re- quired in the image. The number of UIDs and GIDs can be overridden with the size option. The option --userns=keep-id uses all the subuids and subgids of the user. The option --userns=nomap uses all the subuids and subgids of the user ex- cept the user's own ID. Using --userns=auto when starting new containers does not work as long as any containers exist that were started with --userns=nomap or --userns=keep-id without limiting the user namespace size. Valid auto options: * gidmapping=CONTAINER_GID:HOST_GID:SIZE: to force a GID mapping to be present in the user namespace. * size=SIZE: to specify an explicit size for the automatic user namespace. e.g. --userns=auto:size=8192. If size is not specified, auto estimates a size for the user namespace. * uidmapping=CONTAINER_UID:HOST_UID:SIZE: to force a UID mapping to be present in the user namespace. The host UID and GID in gidmapping and uidmapping can optionally be pre- fixed with the @ symbol. In this case, podman will look up the intermedi- ate ID corresponding to host ID and it will map the found intermediate ID to the container id. For details see --uidmap. container:id: join the user namespace of the specified container. host or "" (empty string): run in the user namespace of the caller. The processes running in the container have the same privileges on the host as any other process launched by the calling user. keep-id: creates a user namespace where the current user's UID:GID are mapped to the same values in the container. For containers created by root, the current mapping is created into a new user namespace. In addition, the init process within the container will run under the cur- rent user's UID. This behavior overrides the image's USER instruction un- less you explicitly set --user. Valid keep-id options: * uid=UID: override the UID inside the container that is used to map the current user to. * gid=GID: override the GID inside the container that is used to map the current user to. * size=SIZE: override the size of the configured user namespace. It is useful to not saturate all the available IDs. Not supported when running as root. nomap: creates a user namespace where the current rootless user's UID:GID are not mapped into the container. This option is not allowed for contain- ers created by the root user. ns:namespace: run the pod in the given existing user namespace. --wait, -w Run pods and containers in the foreground. Default is false. At any time you can run podman pod ps in another shell to view a list of the running pods and containers. When attached in the tty mode, you can kill the pods and containers by pressing Ctrl-C or receiving any other interrupt signals. All pods, containers, and volumes created with podman kube play is removed upon exit.
