In this blog, we will try to learn how we can install TeamCity Server and Agent as a docker image and the required configuration.
What is TeamCity?
- TeamCity is a build management and continuous integration server from JetBrains.
Features of TeamCity
- It provides several ways to reuse the settings of the parent project to subproject.
- For a single build, Teamcity can take source code from two different VCS.
- It can also detect builds which are hung.
- For easy access, you can mark build.
- We can run parallel builds simultaneously in different environments.
- Formatted text can be set for Build status which makes the server perform some actions.
- You can build docker images in separate steps with the extension to other runners (Gradle, Maven, etc.).
- Testers can be replaced with agents.

Advantages of TeamCity

- Automated Deployment
- Integration using any SCM tools.
- Check History and Status of Build JOBS.
Disadvantages of TeamCity
- Upgrading from one version to another causes a lot of work to be done.
- Teamcity is not open source after 3 agents and 100 builds users need to take license and to be paid.
- The user community for TeamCity is very less as compared to other CI tools in the market.
