Unmet requirements: docker.server.osType contains linux Follow
Hi,
I have a Linux (Ubu 18.04) based TC installation with 2018.2.4 (build 61678).
docker and docker-compose is installed locally:
root@sd7:~# docker -v
Docker version 18.09.2, build 6247962
root@sd7:~# docker-compose -v
docker-compose version 1.17.1, build unknown
On the agent I see the following variables:
| docker.version | 18.09.2 |
|---|---|
| dockerCompose.version | 1.17.1 |
Thus, the agent is uncompatible / unmet:

Unmet requirements:
docker.server.osType contains linux
I can't understand this, other related posts are not identical / because of other issues.
Thanks for help,
Matthias

Hi,
the issue with "docker.server.osType" not showing up usually means that the docker command run from the agent cannot connect with the docker daemon running. This is usually due to a lack of permissions, as docker by default only allows connections from root and users of the group docker: https://docs.docker.com/install/linux/linux-postinstall/
Please make sure to set the appropriate configuration (the user running the build agent is a member of the dockergroup). Then, restart the agent. That should make it work. If it doesn't you might need to restart the session to ensure that the group changes take effect.
Thanks, that was it!
(P.S.: Didn't find any TC docu about all these nasty prerequisites for docker support, e.g. also how to configure the best way things like registry logins etc.).
I've added a comment to document it in an issue we had here about it: https://youtrack.jetbrains.net/issue/TW-52609 to try and improve our documentation about it.
Hi Dushant,
first of all, please don't post in multiple posts with a different question. It creates extra workload for us and it's not going to speed up any response.
Secondly, the likely answer to your problem is the first answer I provided in this same thread, and is very likely actually related to your docker installation and not to teamcity in itself. Please test it out.
