Is monorepo good for Microservices?

A monorepo removes barriers and silos between teams, making it easier to design and maintain sets of microservices that work well together. Standardization. With monorepos, it is easier to standardize code and tooling across the teams.

What is GitLab monorepo?

In the context of GitLab pipelines, a DAG is chain of jobs created by specifying the dependencies between jobs. This is in contrast to grouping jobs by stage, which allows for parallelisation of jobs but does not permit the creation of multiple CI/CD pipelines in a single repository.

Does GitLab have CI CD?

GitLab CI/CD is the part of GitLab that you use for all of the continuous methods (Continuous Integration, Delivery, and Deployment). With GitLab CI/CD, you can test, build, and publish your software with no third-party application or integration needed.

How do I enable CI for my project on GitLab?

Enable CI/CD in a project

On the top bar, select Menu > Projects and find your project.
On the left sidebar, select Settings > General.
Expand Visibility, project features, permissions.
In the Repository section, turn on or off CI/CD as required.

Should Microservices be in separate repositories?

Clear ownership: Having separate repository for a particular service is a definite microservice way of doing things because the team that owns that service is clearly responsible for independently develop and deploy the full stack of that microservice.

Who is using Monorepo?

Google is one of many large companies that famously uses a monorepo. Google decided early on to use a monorepo — and scaled it up as the company grew. In 2015, the Google monorepo held: 86 terabytes of data.

How do I manage monorepo?

Best Practices for Monorepo Management Maintain branch hygiene. Keep branches small, consider adopting trunk-based development. Use pinned dependencies for every project. Upgrade dependencies all at once, force every project to keep up with the dependencies.

How do I deploy monorepo?

How to Deploy from a Monorepo

Visit the Apps page and click Create App.
Select the GitHub repository that contains your source code and specify the branch or tag in your repository that contains your app’s source code.
In the Source Directory field, specify the folder that contains the source and click Find Directory.

How does CI CD works?

Definition. CI and CD stand for continuous integration and continuous delivery/continuous deployment. Automated build-and-test steps triggered by CI ensure that code changes being merged into the repository are reliable. The code is then delivered quickly and seamlessly as a part of the CD process.

How CI CD works in Gitlab?

Continious integration (CI) starts with you. You share new code in a merge request (MR), you trigger a pipeline. Build, test, and validate—GitLab does the rest. Continuous delivery (CD) puts your hard work into action, handing off CI-validated code to your application via structured deployment pipelines.

What is the GitLab CI / CD pipeline in monorepos?

Basically, the GitLab CI/CD pipeline consists of several stages such as build, test, and deploy. This pipeline is configured with a file called .gitlab-ci.yaml stored in the root of our repository.

What to do in case of monorepo in GitLab?

In case of a monorepo, we have to make sure the right stages of the GitLab CI/CD pipeline are triggered. Moreover, we usually want to build, test and deploy only those services of our application, which have been changed — and not all services together, because this could be very time consuming.

How many.gitlab-ci.yml files per repository?

As of right now it is only possible to have at most one .gitlab-ci.yml file per repository. However multiple projects/codebases are housed in one repo when using monorepos which makes it more difficult to use with GitLab CI. I will show 2 approaches that tackle this issue.
