Introduction

Usually, Docker stacks on a system are all located within the same folder, e.g., /opt. If these stacks are properly set up with a docker-compose.yml file, a simple docker compose pull followed by a docker compose up -d will update the stack.

To have this done automatically for many stacks, I wrote the following script.

Code

Put the code below into a file, e.g., docker_update.sh, and make it executable: chmod +x docker_update.sh.
