Manage containers

Containers are generally managed using standard Docker commands and the supplementary wrapper, fjell, as described in Shell Aliasese.

Creation

All services are defined in myApplication/docker-compose.yaml. To start single containers, use fjell up myApplication; for entire stacks, use fjell up myStack. This command creates any missing containers and starts them.

Starting and stopping

Initiate container startup or shutdown with fjell start and fjell stop, respectively. Note that to stop an entire stack without deleting its containers, each container must be stopped individually. Using fjell down myStack will stop and remove the containers.

Removal

Remove containers simply with fjell rm myApplication after stopping them. Entire stacks can be removed using fjell down myStack.

Updates

Docker images can be updated in different ways, depending on personal taste. For a deeper dive into automated options, check out this blog post. They can also be manually updated:

• Stop the running container with fjell stop myApplication
• Back up data in myApplication/data
• Review the changelog of the new application version
• Set the new image tag inmyApplication/docker-compose.yaml or pull the new image with docker pull
• Remove the old container with fjell rm myApplication
• Start the new container with fjell up myAppliction
