Working with TeamCity + Docker to setup a CI pipeline for a Java REST app

Java REST App

Here is the Docker command to run the app with a Tomcat 8.0 server. Please take care that we have to use Java 1.7 because of this specifical Tomcat version. I added the war copy command, so our app will be deployed automatically.

docker run --rm -v /your_path/java-teamcity_test/java test/target/javatest.war:/usr/local/tomcat/webapps/javatest.war -it -p 8585:8080 --name=tomcat tomcat:8.0

If you need to check the deployment, logs, or setup of Tomcat container use this command:

docker exec -it tomcat /bin/bash

Test the app going to:

http://localhost:8585/javatest

I added two more rest services a dummy hello call /javatest/hello and a test/id validation test/error.

TeamCity Server

First create two folders /data and /logs to storage what TC needs. This image will take a while to download (current local size used: 1.52GB).

docker run -it --name tcserver -v /your_path/teamcity/data:/data/teamcity_server/datadir -v /your_path/teamcity/logs:/opt/teamcity/logs -p 8111:8111 jetbrains/teamcity-server

I'm using the internal HSQLDB database provided by the image to avoid futher setup, if you have time use an external option!

TeamCity Agent

There is two version for agents, in my case, I used the standard one, you can try with the minimal. The standard version is another heavy image to download, so be patient (current local size used: 1.03GB).

docker run --name tcagent -it -e SERVER_URL="your_ip:8111" -p 9090:9090 -v /your_path/teamcity/agent:/data/teamcity_agent/conf jetbrains/teamcity-agent

TeamCity Agents will not work with localhost as SERVER_URL, so please use your IP. If you change your IP or network connection, modify serverUrl inside buildAgent.properties then restart the docker

docker start tcagent

Adding local agent to the server

The final step, you have to authorize manually your local agent here:

http://localhost:8111/agents.html?tab=unauthorizedAgents

Deploying the artifact to a Tomcat container

Tomcar container

In the new version on TeamCity is possible to deploy directly to a container locally or remote, we are going to use the same Tomcat 8.0 image, but adding context and user setup. Go to /tomcat folder and then build the Dockerfile.

docker build -t twogg/tomcat .

Now run the container, we re using admin/admin as user and password, and 8787 is going to be our deploy port for TeamCity.

docker run -d -p 8787:8080 --name tctomcat twogg/tomcat
