I run teamcity-agent by docker image on 172.17.0.3, and I run teamcity-agent by docker image to with

```

docker run -itd -name tc-agent -e SERVER_URL="172.17.0.3:8111" \

-v /www/wwwroot/teamcity/data/teamcity_agent/conf:/data/teamcity_agent/conf \

jetbrains/teamcity-agent

```

then it can't connect teamcity-server.

here's log:

Hi,

Can you verify the command used to start the jetbrains/teamcity-server container? Are you able to access the server from your web browser? Also, have you completed the TeamCity Server startup and accepted the license agreement?

It is fairly typical to use a command like the below to start the TeamCity server container:

docker run -it --name teamcity-server-instance  \
    -v <path-to-data-directory>:/data/teamcity_server/datadir \
    -v <path-to-logs-directory>:/opt/teamcity/logs  \
    -p <port-on-host>:8111 \
    jetbrains/teamcity-server

Then you would use the Host IP address and port for the server url on the TeamCity agent:

docker run -it -e SERVER_URL="<Docker Host IP Address>:<Port on Host>"  \ 
    -v <path to agent config folder>:/data/teamcity_agent/conf  \      
    jetbrains/teamcity-agent
