In this blog we will try to learn how we can install TeamCity Server and Agent as docker image and required configuration.

What is TeamCity?

• TeamCity is a build management and continuous integration server from JetBrains.

CI/CD Pipeline

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.
