#### Summary The instructions on the [Local Machine Setup using Docker](https://docs.mattermost.com/install/docker-local-machine.html) 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): ``` 2021-01-11 21:14:51+00:00 [Note] [Entrypoint]: Creating database mattermost_test 2021-01-11 21:14:51+00:00 [Note] [Entrypoint]: Creating user mmuser 2021-01-11 21:14:51+00:00 [Note] [Entrypoint]: Giving user mmuser access to schema mattermost_test 2021-01-11 21:14:51+00:00 [Note] [Entrypoint]: Stopping temporary server 2021-01-11T21:14:51.810197Z 0 [Note] Giving 0 client threads a chance to die gracefully [...] 2021-01-11T21:14:53.625329Z 0 [Note] InnoDB: Shutdown completed; log sequence number 12617575 [...] 2021-01-11 21:14:53+00:00 [Note] [Entrypoint]: Temporary server stopped 2021-01-11 21:14:53+00:00 [Note] [Entrypoint]: MySQL init process done.

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. ---

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. ---
