No output received when running report, docker API version mismatch #21

Running lumogon returns nothing on my server.

docker run --rm -v /var/run/docker.sock:/var/run/docker.sock puppet/lumogon report

Running with debug shows a version mismatch

docker run --rm -v /var/run/docker.sock:/var/run/docker.sock puppet/lumogon report --debug

@remh @sbeaulie thanks for reporting the issues. We'll both clarify in the docs which versions of Docker are supported at the moment, and also look at expanding that support to older versions too.

finid commented 7 years ago

@garethr, so what's the minimum Docker version needed to run Lumogon?

I'm having the same issue.

johnmccabe commented 7 years ago

@finid @sbeaulie for the moment can you specify the API version your server supports when invoking the report/scan command, for example:

docker run --rm -v /var/run/docker.sock:/var/run/docker.sock -e DOCKER_API_VERSION=1.24 puppet/lumogon report
sbeaulie commented 7 years ago

@johnmccabe I can confirm adding the docker api version environement variable fixed the issue

finid commented 7 years ago

If anybody is still running Docker 1.x series, I think it's better to delete that and install Docker CE. That fixed it for me.

stahnma commented 7 years ago

@garethr @johnmccabe yeah, without the -e DOCKER_API_VERSION=1.24 the default docker install on EL7 isn't compatible. We may want to document that on the main lumogon page, or update the payload to work there, if that's reasonable.

garethr commented 7 years ago

@stahnma we're working out the best approach at the moment. We'll certainly be improving error messages and updating the README with the workaround. We'll also likely do some autodetection under the hood so Lumogon simply does this for you.

We do however want to keep up with features in recent Docker releases as well, and given Docker's release cycle we'll probably have something that support which follows that.

This was fixed with https://github.com/puppetlabs/lumogon/commit/7a0d9703c9db526f4b1adce38e16742a1e62b38a#diff-3f2a717db5d6f646b50b72c60b0117f6L47.
