[jira] [Commented] (MESOS-1747) Docker image parsing for private repositories

["Timothy Chen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-1747?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14117583#comment-14117583 ] 

Timothy Chen commented on MESOS-1747:
-------------------------------------

For 0.20.0 you can specify a private repository but not with a port (my-private-repo/image:tag)
There is a fix in master now that allows private repositories with port information.

About the '-' character, I don't do anything special checking for this as your image is directly passed to Docker CLI, so the error message you see is directly from the Docker CLI itself which Docker doesn't allow you to.

> {noformat}
> The message indicates only one colon character is allowed, but to supply a port number for a private docker repository host you need to have two colons.
> Also if you use a '-' character in a host name you also get an error:
> {noformat}
> Invalid namespace name (docker-repo), only [a-z0-9_] are allowed, size between 4 and 30
> {noformat}
> The hostname parts should not be limited to [a-z0-9_].
