TeamCity Interview Questions

TeamCity Interview Question and Answers

TeamCity is a continuous integration and deployment tool for software development teams. It is used by companies like Yahoo!, LinkedIn, and other large enterprises. In this blog, we have compiled a list of TeamCity Interview Questions to help you crack that interview.

Q1) What is the purpose of the TeamCity tool?

Ans:  A Java-based CI server is called TeamCity. It enables integration, and coding, and is simpler to configure with straightforward procedures. On TeamCity, many platforms and environments are used concurrently for parallel builds.

Q2) Is TeamCity an open-source tool?

Ans:  JetBrains offers TeamCity, a server for continuous deployment and building management. Commercial software with a proprietary license was first made available on October 2, 2006; it comes with three free Build Agent licenses as well as a freemium license for up to 100 build configurations.

Q3) Is TeamCity a tool for CDs?

Ans:  A general-purpose CI/CD solution like TeamCity offers maximum flexibility for all types of development methods and processes. You can quickly check the status of your builds, learn what prompted them, get the most recent build artifacts, and more using the Projects Overview.

Q4) How does TeamCity deployment work?

Ans. TeamCity offers the build configuration of the Deployment type. This type can be used to identify build settings that perform deploying to a specific environment. Typically, these build configurations depend on the works whose results they deploy via a snapshot or an artifact.

Q5) What does DevOps TeamCity mean?

Ans:  TeamCity is a consumer-friendly continuous integration (CI) server for DevOps, build engineers, and professional developers. It is simple to set up and completely free for open-source projects and small teams.

Q6) Explain a TeamCity build configuration

Ans:  The build configuration name will be suggested by TeamCity, and it will configure the remaining options for you: It will choose the VCS repository's type and establish the VCS root. It will automatically detect the default branch for a Git repository. In the VCS root settings, you can choose to change it now or in the future.

Q7) Is TeamCity software for continuous integration?

Ans:  Developers and build engineers may easily set up and use Jet Brains TeamCity, a free continuous integration (CI) server, with the Professional Server License.

Q8) What exactly is a TeamCity build?

Ans:  A build in TeamCity is a procedure that includes one or more steps and completes a specific CI/CD task. You are prepared to set up and run your first build once you have installed and launched TeamCity according to the instructions provided here.

Q9) In what location are TeamCity build logs kept?

Ans:  On the TeamCity server computer, the logs are kept in plain text files on a disc directory (often in /logs).

Q10) Are private builds triggered automatically?

Ans:  It is not possible to start the private build automatically. If you wish to construct the modifications you have stored in a shelve-set, you must queue a private build. Before checking your code in, you can test changes using a private build.

Q11) Explain TeamCity build agent

Ans:  A TeamCity build agent is a software application that launches the actual build operations after listening for commands from the TeamCity server. It is set up and installed independently of the TeamCity server.

Q12) Is TeamCity a scheduler or a tool for building?

Ans:  Build tools include Teamcity. It is a control and continuous integration server that runs on Java and is licensed under Javabite. Because it focuses primarily on build automation, it may be utilized everywhere without any effort.

Q13) What does TeamCity's artifact path mean?

Ans:  Build artifacts are files generated by the build that are saved on the TeamCity server and can be downloaded via the TeamCity UI or used as prerequisites for other builds.

Q14) What is a job in TeamCity?

Ans:  A software project, a particular version or release of a project, or any other logical collection of build configurations can all be considered to be a TeamCity project. There is a name, an ID, and an optional description for the project. User roles and permissions are maintained in TeamCity on a project-by-project basis.

Q15) What database is used by TeamCity?

Ans:  TeamCity by default makes use of a HyperSQL DataBase-based internal database (HSQLDB). The default configuration stores the database files in, which is typically BuildServer.

Q16) What is kept in the DB by TeamCity?

Ans:  In a SQL database, TeamCity keeps track of users, build outcomes, build histories, and certain runtime information.

Q17) How do I recover a TeamCity backup?

Ans: 

• Enter the Data Directory's path on the TeamCity First Start page and select Restore from backup.
• You can upload a ZIP package containing the backed-up data or enter the following command to the backup directory on the TeamCity server.
• Select the desired database.
• Continue the restoration.

Q18) What does TeamCity's meta runner mean?

Ans:  In essence, a meta-runner is a set of build steps from one build configuration that can be applied in another. A meta-runner is an XML definition that includes build steps, prerequisites, and characteristics that you may use in XML definitions of other build configurations. Using the online UI, TeamCity enables the extraction of meta-runners.

Q19) Jenkins vs. TeamCity: Which is preferable?

Ans:  TeamCity is a JetBrains-exclusive product, whereas Jenkins is an open-source continuous integration platform. Jenkins provides a robust ecosystem of plugins and integrations, whereas TeamCity is simpler to set up and operate.

Q20) How can you make TeamCity's agents available?

Ans:  When using the web UI, agents can be manually enabled or disabled by clicking the status icon next to their name. You may also add a note and choose whether TeamCity should automatically disable or enable the agent after a certain amount of time. TeamCity will adhere to the guidelines and display the comment icon.
