What is CircleCI built in?

Clojure
Most of CircleCI is written in Clojure and it has been this way since almost the beginning. Early development included Rails, but by the time that CircleCI was released to the public, it was written entirely in Clojure. Clojure is still at our platform’s core.

What is restore cache in CircleCI?

Restoring cache CircleCI restores caches in the order of keys listed in the restore_cache step. Each cache key is namespaced to the project, and retrieval is prefix-matched. The cache will be restored from the first matching key. If there are multiple matches, the most recently generated cache will be used.

What is the difference between Jenkins and CircleCI?

In conclusion, the key difference between CircleCI vs Jenkins is that Jenkins is more secure and elaborates; CircleCI is lightweight and open. Therefore for faster deployment jobs, one can execute their codes on CircleCI as it deploys on scalable and robust cloud servers.

What are Gitlab stages?

A typical pipeline might consist of four stages, executed in the following order:

• A build stage, with a job called compile .
• A test stage, with two jobs called test1 and test2 .
• A staging stage, with a job called deploy-to-stage .
• A production stage, with a job called deploy-to-prod .

Is CircleCI free?

Users on our Free plan can build up to 250 minutes per week using their 2,500 credits. On the Free plan, users can build with the Medium compute option (2 vCPUs with 4 GB of memory) on Linux machines, which uses 10 credits per minute.

Is Jenkins CI or CD tool?

Jenkins is a leading open-source CI/CD tool used to deliver apps faster by introducing automation at different software development stages. It is written in the JAVA Programming language and is a server-based application using servers such as Apache Tomcat.

How do I get a job in GitLab?

To create a group of jobs, in the CI/CD pipeline configuration file, separate each job name with a number and one of the following:

1. A slash ( / ), for example, test 1/3 , test 2/3 , test 3/3 .
2. A colon ( : ), for example, test 1:3 , test 2:3 , test 3:3 .
3. A space, for example test 0 3 , test 1 3 , test 2 3 .

How does monorepo with CircleCI conditional workflows work?

There is a new experimental script that allows conditioning workflows on specific path changes using advanced pathspec. See v2 for more details. Monorepos bring simplicity to the development process, but raise the complexity of automated builds and deploy.

Which is an example of a CircleCI monorepo script?

The new script is planned to be published as CircleCI orb to allow for easier integration. Monorepo brings simplicity to the development process by having all code in one place, but raises the complexity of automated builds and deploy. For a relatively small monorepo it can be acceptable to have builds run for each service on every change.

Can a monorepo be run on every change?

For a relatively small monorepo it can be acceptable to have builds run for each service on every change. However, if you have a monorepo with a dozen of services/components, even the smallest change can introduce big delays in the CI process making it less efficient.

How to configure CircleCI for multiple workflows?

CircleCI doesn’t yet support multiple configuration files (which would be nice for monorepos), so you start by creating a .circleci/config.yml where you’ll define all the jobs and workflows for the entire monorepo.
