OCF_HEARTBEAT_PODMAN(7)

NAME
ocf_heartbeat_podman - Podman container resource agent.

SYNOPSIS

podman [start | stop | monitor | meta-data | validate-all]

DESCRIPTION

The podman HA resource agent creates and launches a podman container based off a supplied podman image. Containers managed by this agent are both created and removed upon the agent's start and stop actions.

SUPPORTED PARAMETERS

image
    The podman 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 podman registry when the image 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 'podman 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 the '-d' option is supplied regardless of this value to force containers to run in the background.

    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 initialized.

    (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 indicate that the container is healthy. A non-zero return code will indicate that the container has failed and should be recovered.

    Note: Using this method for monitoring processes inside a container is not recommended, as containerd 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 terminates 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)

reuse
    Allow the container to be reused once it is stopped. By default, containers get removed once they are stopped. Enable this option to have the particular one persist when this happens.

    (optional, boolean, default 0)

drop_in_dependency
    Use transient drop-in files to add extra dependencies to the systemd scopes associated to the container. During reboot, this prevents systemd to stop the container before pacemaker.

    (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. Suggested interval: 30s.

meta-data
    Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5s.

validate-all
    Performs a validation of the resource configuration. Suggested minimum timeout: 30s.
