Helper Script

A helper script, using casey/just is in bin/cli. It can be used to quickly start an ephemeral (or persistent) container.

$ bin/cli help

Available recipes:
    clean              # Remove the persistent container
    default            # Invoke the 'run' recipe
    help recipe="help" # Display this listing. Detailed help is available with 'help recipe_name'.
    persist            # Run (or attach to) a persistent container
    pull               # Pull the latest version of the image
    restart            # Remove a running container, and run the default recipe
    run                # Run an ephemeral container.
    save i=image       # Save the running container as a new image


$ bin/cli
~ $ ^D
exit

$ bin/cli persist
~ $ ls
~ $ 
exit

$ podman cp foo.json cli:/home/cli  # copy a file to the persistent container

$ bin/cli persist
~ $ ls
foo.json
~ $ ^D
exit

Bonus - the same script could be used to start other containers:

$ bin/cli image=alpine:edge
/ # ^D
