podman-secret-create(1) General Commands Manual podman-secret-create(1) NAME podman-secret-create - Create a new secret SYNOPSIS podman secret create [options] name file|- DESCRIPTION Creates a secret using standard input or from a file for the secret content. Create accepts a path to a file, or -, which tells podman to read the secret from stdin A secret is a blob of sensitive data which a container needs at runtime but is not stored in the image or in source control, such as usernames and passwords, TLS certificates and keys, SSH keys or other important generic strings or binary content (up to 512 kB in size). Secrets are not committed to an image with podman commit, and do not get committed in the archive created by a podman export command. Secrets can also be used to store passwords for podman login to authen- ticate against container registries. OPTIONS --driver, -d=driver Specify the secret driver (default file). --driver-opts=key1=val1,key2=val2 Specify driver specific options. --env=false Read secret data from environment variable. --help Print usage statement. --ignore=false If a secret with the same name already exists, do not return an error and return the existing secret's ID instead of creating a new one. Cannot be used with --replace. The default is false. --label, -l=key=val1,key2=val2 Add label to secret. These labels can be viewed in podman secrete in- spect or ls. --replace=false If existing secret with the same name already exists, update the se- cret. The --replace option does not change secrets within existing containers, only newly created containers. Cannot be used with --ig- nore. The default is false. SECRET DRIVERS file Secret resides in a read-protected file. pass Secret resides in a GPG-encrypted file. shell Secret is managed by custom scripts. An environment variable SECRET_ID is passed to the scripts (except for list), and secrets are communi- cated via stdin/stdout (where applicable). Driver options list, lookup, store, and delete serve to install the scripts: [secrets] driver = "shell" [secrets.opts] list = lookup = store = delete = EXAMPLES Create the specified secret based on a local file. echo -n mysecret > ./secret.txt $ podman secret create my_secret ./secret.txt Create the specified secret via stdin. $ printf <secret> | podman secret create my_secret - Create or rotate a cryptographically secure random secret just under the maximum 512000 bytes via stdin. openssl rand -base64 378000 | podman secret create --replace my_secret - Mount a local file-based secret securely in a container. podman run --rm --secret source=my_secret,type=mount,uid=1001,gid=1001,mode=440 docker.io/library/alpine ls -l /run/secrets/my_secret Create gpg encrypted secret based on a local file using the pass dri- ver. $ podman secret create --driver=pass my_secret ./secret.txt.gpg Create a secret from an environment variable called 'MYSECRET'. $ podman secret create --env=true my_secret MYSECRET SEE ALSO podman(1), podman-secret(1), podman-login(1), podman-run(1) HISTORY • January 2021, Originally compiled by Ashley Cui acui@redhat.com <mailto:acui@redhat.com> • February 2024, Added example showing secret creation from an environ- ment variable by Brett Calliss brett@obligatory.email <mailto:brett@obligatory.email> • May 2025, Added example showing secure secret generation / rotation & mounting by Stuart Cardall podman-secret-create(1)
