Docker Launcher: Versions and Nightly Builds doesn't work

[vparfonov]

Can't use nightly builds.
Try to use this docs https://eclipse-che.readme.io/docs/usage-docker#versions-and-nightly-builds

1.docker run --rm -t -v /var/run/docker.sock:/var/run/docker.sock eclipse/che:nightly start

Unable to find image 'eclipse/che:nightly' locally

  See 'docker run --help'.

1. docker run --rm -t -v /var/run/docker.sock:/var/run/docker.sock -e CHE_VERSION=4.6.0 eclipse/che start

#1 it seems nightly tag has not been deployed for eclipse/che image
will check with @riuvshin
you could use for now codenvy/che-launcher

docker run --rm -t -v /var/run/docker.sock:/var/run/docker.sock codenvy/che-launcher:nightly start

about #2 only latest shipped images are there
https://hub.docker.com/r/eclipse/che/tags/

4.6.0 may not have been shipped
you should use 4.6.2 tag or latest

Yes florent beat me to it. I am going to close this issue because there is another issue which is working to get the nightly tag for eclipse/Che added for ci. This has been a known limitation for a bit and just waiting for roman to get the ci systems updated.

[TylerJewell]

I have updated the docs as we should not have listed eclipse/Che yet in that page until the ci systems were updated.

Btw @vparfonov, I researched for two hours a way to try and query docker hub to return valid list of versions to do a version check. Unfortunately there is not a clean way to query dockerhub for a list of tags without screen scraping a page. So we do not have a clean way to check if a version requested is valid without embedding a list in the cli.
