@mikaello like this? #46

I've also pushed a test tag :issue45-labels if you want to test.

Exactly (or almost, minor change commented in PR), thanks a lot for your swift reply!

I've also pushed a test tag :issue45-labels if you want to test.

Currently the labels are not in the final build, as mentioned in the PR:

$ docker inspect mendhak/http-https-echo:issue45-labels --format '{{ .Config.Labels }}'
map[]

[mendhak]

Ah thanks for that command. OK I pushed a different tag now,

docker pull mendhak/http-https-echo:labels
docker inspect lscr.io/linuxserver/transmission --format '{{ .Config.Labels }}'

And this is the output I get

map[org.opencontainers.image.description:Docker image that echoes request data as JSON; listens on HTTP/S, with various extra features, useful for debugging. org.opencontainers.image.documentation:https://github.com/mendhak/docker-http-https-echo/blob/master/README.md org.opencontainers.image.licenses:MIT org.opencontainers.image.source:https://github.com/mendhak/docker-http-https-echo org.opencontainers.image.title:http-https-echo org.opencontainers.image.url:https://github.com/mendhak/docker-http-https-echo]

Well it looks like a mapping of some sort. Looking better now?

Looks very good! You can add json in the formatting string to get JSON:

$ docker inspect mendhak/http-https-echo:labels --format '{{json .Config.Labels }}' | jq
{
  "org.opencontainers.image.description": "Docker image that echoes request data as JSON; listens on HTTP/S, with various extra features, useful for debugging.",
  "org.opencontainers.image.documentation": "https://github.com/mendhak/docker-http-https-echo/blob/master/README.md",
  "org.opencontainers.image.licenses": "MIT",
  "org.opencontainers.image.source": "https://github.com/mendhak/docker-http-https-echo",
  "org.opencontainers.image.title": "http-https-echo",
  "org.opencontainers.image.url": "https://github.com/mendhak/docker-http-https-echo"
}

Thanks again for that. :27 is now in Docker Hub.
