Local Machine Setup using Docker not working

Summary

The instructions on the Local Machine Setup using Docker page, to be used for quick mattermost evaluation on a docker host, are not working.

Steps to reproduce

On docker host, run the specified command (ie “docker run --name mattermost-preview -d --publish 8065:8065 --add-host dockerhost:127.0.0.1 mattermost/mattermost-preview”).

Expected behavior

A mattermost service should have been running on my host on port 8065.

Observed behavior

The container had exited with error code 1. Looking in the logs, I have the following (trying to strip out irrelevant messages):

Hello, @rara I’m sorry to hear you’re having issues, I hope we can help!

@jasonblais does this look like it’s a build error with the syntax to you as well?

If it helps, I tried the older version of the docker image (mattermost-preview:5.26.0) and it worked fine. That might help locate the problem.

So it’s not urgent for me, anymore. But it might be good to fix this for your next release.

Looks like something may have gone wrong. I’ll share with our DevOps team.

Thanks for reporting it @rara, and glad to hear a previous version is working fine for you!

Edit: I’ll post back here once I’ve heard back from the team.

Sounds good, thank you!

I have the same error when starting the newest version on docker:

Error: failed to load configuration: unable to load on store creation: parsing error at line 109, character 42: json: cannot unmarshal string into Go struct field TeamSettings.TeamSettings.ExperimentalDefaultChannels of type string stderr

Older version still works.

Thanks for letting us know! The issue was escalated last week, and our build engineer will be looking at this error soon.
