I have a legacy PHP web-app which I’d like to modernise via docker-compose.
The app formerly used cron to run schedule commands, and I’d like to substitute Apache Airflow for this.
So, I have a docker-compose file that looks like this (simplified):
services: php: build: . container_name: web ports: - '8080:80' ... airflow: image: puckel/docker-airflow:1.10.0-2 ports: - "8081:8080" command: webserver ...
I’d like Airflow to be able to run commands in the PHP container. Two reasons for doing it this way:
- I’m struggling to create an image based on Airflow which installs PHP and my app dependencies. Can’t
sudoin a Docker image that is based on
- I’d like to avoid setting up a mirror of my app and its dependencies within the Airflow image
What’s the best way of doing this? Would it be to ssh from the airflow container to the php container. Could someone advise on what I’d need to do to enable this?
