Consider chown for buildagent user during 'initialization' (in addition to the Dockerfile), either:
A) in this entrypoint
B) As an entry in /services/
chown -R buildagent:buildagent /opt/buildagent
Otherwise this may break for users of jetbrains/teamcity-agent which run "Docker from the host". The permissions need to be set at container 'runtime' since the checkout dir and temp dir are bind-mount VOLUMEs; as explained here: https://hub.docker.com/r/jetbrains/teamcity-agent/
Options -v /opt/buildagent/work:/opt/buildagent/work and -v /opt/buildagent/temp:/opt/buildagent/temp are required if you want to use Docker Wrapper on this build agent.

@stayclassychicago @yaegor user buildagent must be part of docker group in teamcity-docker-agent container in order to be able to run dockerized tasks.
Shall we run usermod -a -G docker buildagent there?

Alternatively, we can create docker group in advance here, and add buildagent user to this group.

I do not think either is necessary for this minimal agent image. The teamcity-docker-agent provisions both:
dockergroup is created in the step to install docker- later in the step the buildagent user is added to docker group

Does this step still work for you? This fails with keyserver communications error (below). Not sure if this is a regional issue (if so are there mirrors for this keyserver) or if you are able to validate this is still successful ?
gpg: keyserver communications error: keyserver unreachable
?: [fd 4]: read error: Connection reset by peer
gpgkeys: HTTP fetch error 7: couldn't connect: eof
gpg: keyserver communications error: public key not found
gpg: keyserver receive failed: public key not found

Yes, it does for me, let me check if ubuntu apt key servers have this key.

Cold you please check if following works for you:
gpg --keyserver keyserver.ubuntu.com --recv-keys B42F6819007F00F88E364FD4036A9C25BF357DD4apt-key adv --keyserver keyserver.ubuntu.com --recv-keys B42F6819007F00F88E364FD4036A9C25BF357DD4
It is weird, that it can't connect; keyserver.ubuntu.com is part of sks pool as well.
Are you able to resolve domain dig +short ha.pool.sks-keyservers.net?

@VladRassokhin could you please review this pr, if you have some free time, of course. |

Currently we're preparing TeamCity 2018.1 release so I don't have spare time to take a look. Probably a month later we would evaluate this PR. |

Hello, I've just pushed a fix for #16 which optionally runs agent under Please let me know if there are any issues with the fix. Thank you! |
