OCF_HEARTBEAT_RKT(7) OCF resource agents OCF_HEARTBEAT_RKT(7) NAME ocf_heartbeat_rkt - rkt container resource agent. SYNOPSIS rkt [start | stop | monitor | meta-data | validate-all] DESCRIPTION The rkt HA resource agent creates and launches a container based off a sup- plied image. Containers managed by this agent are both created and removed upon the agent's start and stop actions. SUPPORTED PARAMETERS image The image to base this container off of. (required, string, no default) name The name to give the created container. By default this will be that resource's instance name. (optional, string, no default) allow_pull Allow the image to be pulled from the configured registry when the im- age does not exist locally. NOTE, this can drastically increase the time required to start the container if the image repository is pulled over the network. (optional, boolean, no default) run_opts Add options to be appended to the 'rkt run' command which is used when creating the container during the start action. This option allows users to do things such as setting a custom entry point and injecting environment variables into the newly created container. NOTE: Do not explicitly specify the --name argument in the run_opts. This agent will set --name using either the resource's instance or the name provided in the 'name' argument of this agent. (optional, string, no default) run_cmd Specify a command to launch within the container once it has initial- ized. (optional, string, no default) mount_points A comma separated list of directories that the container is expecting to use. The agent will ensure they exist by running 'mkdir -p' (optional, string, no default) monitor_cmd Specify the full path of a command to launch within the container to check the health of the container. This command must return 0 to indi- cate that the container is healthy. A non-zero return code will indi- cate that the container has failed and should be recovered. Note: Using this method for monitoring processes inside a container is not recommended, as rkt tries to track processes running inside the container and does not deal well with many short-lived processes being spawned. Ensure that your container monitors its own processes and ter- minates on fatal error rather than invoking a command from the outside. (optional, string, no default) force_kill Kill a container immediately rather than waiting for it to gracefully shutdown (optional, boolean, no default) SUPPORTED ACTIONS This resource agent supports the following actions (operations): start Starts the resource. Suggested minimum timeout: 90s. stop Stops the resource. Suggested minimum timeout: 90s. monitor Performs a detailed status check. Suggested minimum timeout: 30s. Sug- gested interval: 30s. meta-data Retrieves resource agent metadata (internal use only). Suggested mini- mum timeout: 5s. validate-all Performs a validation of the resource configuration. Suggested minimum timeout: 30s.
