Docker Compose syntax: Volume or Bind mount?
- maximization 7y agoCompose allows you to configure volumes using a short syntax format: `[SOURCE:]TARGET[:MODE]` In practice, this leads to different string variations. Every time I read a docker-compose.yml file, I had to refer to the docs or run a quick test to figure out if a volume or a bind mount is used. I wrote a short guide so I wouldn't have to look this stuff up anymore and be able to memorise it by heart. The gist of it is: 1. No source -> anonymous volume 2. Non-path source -> named volume (defined in a top-level `volumes` key) 3. Relative or absolute path source -> bind mount Hope this helps some of you out there that trip over this syntax like me. Stay home and be safe!
