Execute bash command after image startup

[Anthony Joyce <an...@omicronmedia.com>]

Hi all,

I want to execute a bash command inside a container after it has already started up. For example, I would like to execute an ssh command that forwards a port from the host to the container. I would like to automate this using the docker-compose.yaml if I can. I am using the official apache-airflow container image. How would I go about doing this? 

Thanks!

Anthony

Thanks again Jarek. That was one of the formats I didn’t try. Appreciate you!

The image has entrypoint that accepts `bash` command and when you run your docker-compose, you are free to provide any startup command (as long as you continue using the default entrypoint)

Your docker compose entries can specify any bash command to run for your docker containers, for example:


airflow-worker:
  command:
    - bash
    - -c
    - |
      run_your_command_here
      airflow worker

This will run "run_your_command_here" before starting the worker.

BTW. You can read more about the "official image" entrypoint and
particularly about running commands here (
https://airflow.apache.org/docs/docker-stack/entrypoint.html#executing-commands
):

The image has entrypoint that accepts `bash` command and when you run your
docker-compose, you are free to provide any startup command (as long as you
continue using the default entrypoint)

Your docker compose entries can specify any bash command to run for your
docker containers, for example:

airflow-worker:
  command:
    - bash
    - -c
    - |
      run_your_command_here
      airflow worker


This will run "run_your_command_here" before starting the worker.
