What is the naming convention for the docker-compose.yml file? Should it always be named like this or am I free to rename it to, for instance, docker-compose-jenkins.yml?
回答1:
default name:
Note that docker-compose.yml is the default name so if you want to use docker-compose up without specifying a filename, you will need to use that format. As mentioned, you can use multiple files as overrides (see docs), by specifying one file per -f argument.
Docker reference:
The -f flag is optional. If you don’t provide this flag on the command line, Compose traverses the working directory and its parent directories looking for a docker-compose.yml and a docker-compose.override.yml file. You must supply at least the docker-compose.yml file. If both files are present on the same directory level, Compose combines the two files into a single configuration.
The configuration in the docker-compose.override.yml file is applied over and in addition to the values in the docker-compose.yml file.

回答2:
You can specify an alternate filename on the command line.
-f, --file FILE Specify an alternate compose file (default: docker-compose.yml)
Ref: https://docs.docker.com/compose/reference/overview/
Given that the tool supports using any file name you'd like, you're free to name the file whatever you'd like. In fact, you can even specify multiple files at once.
