[Installation] "'compose' is not a docker command"
$ docker compose build
docker: 'compose' is not a docker command.
See 'docker --help'
May be it is docker-compose
instead but it has other issues:
$ docker-compose build
ERROR: The Compose file './docker-compose.yml' is invalid because:
'name' does not match any of the regexes: '^x-'
You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.
For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/
