generaltao725/command-runner is the tool for running commands in docker containers. It is useful for container maintenance operations.
The easiest way of running the tool is using docker-compose. Here is an example of the tool usage.
You have to add an environment variable in command-runner service - COMMAND_RUNNER_GROUP. It configures the group of containers the service will be working with. It can be populated
with any string in kebab-case style.
Target services are configured using labels with a root path command-runner.. Here are the labels:
| Label | Required | Description |
|---|---|---|
| command-runner.group | yes | A group name that command-runner service will be working with |
| command-runner.user | no | A user that will run the command |
| command-runner.shell | yes | A command shell path and parameters the command will run in |
| command-runner.command | yes | A command that will be executed in a service |
You can also define after-all.sh and before-all.sh bash and mount them into /etc/runner/scripts/shared directory in command-runner container. The scripts allow you to
run bash scripts before and after running commands. The scripts will be running in the host. Both scripts are optional and are useful for some preparations and cleanup.
You can run the configured commands and scripts using docker-compose:
docker compose exec command-runner runner [arguments]The runner command can take any amount of arguments, which will be passed to the after-all.sh and before-all.sh scripts.
