I got a legacy project running with docker-compose . A year ago it was starting with the configuration below. Now it's throwing an error: exec /usr/local/bin/docker-entrypoint.sh: exec format error I would like to run the container with the CMD configuration. I found in the web to add #!/bin/bash is required to avoid this error, which I added to the Dockerfi

I am working on a project that use docker-compose in their makefile. How could I forward all the calls (and their arguments) from docker-compose to docker compose ? I created an alias: alias docker-compose="docker compose" It
I have read the docker documentation about restart policy of containers. However, I failed to understand the difference between on-failure and unless-stopped . When will I use one over the other? In which situations will a certain policy lead to starting a container and the other policy not?
