Which command is used to update only the Docker image?
/var/discourse# ./launcher -h
Usage: launcher COMMAND CONFIG [--skip-prereqs] [--docker-args STRING]
Commands:
start: Start/initialize a container
stop: Stop a running container
restart: Restart a container
destroy: Stop and remove a container
enter: Open a shell to run commands inside the container
logs: View the Docker logs for a container
bootstrap: Bootstrap a container for the config based on a template
run: Run the given command with the config in the context of the last bootstrapped image
rebuild: Rebuild a container (destroy old, bootstrap, start new)
cleanup: Remove all containers that have stopped for > 24 hours
start-cmd: Generate docker command used to start container
Options:
--skip-prereqs Don't check launcher prerequisites
--docker-args Extra arguments to pass when running docker
--skip-mac-address Don't assign a mac address
--run-image Override the image used for running the container
My use case is:
Currently, during the build process, if a Docker image update is required but the server’s network connection is poor, the process gets stuck at the image update step for a very long time. I would like to have a dedicated command for updating the Docker image, so that I can update the image in advance separately and then build the code without any rush. For example:
./launcher pull-docker
I know I can manually create a working version, but I would still prefer if the official team could provide one.
