How to deploy gitlab application in Alibaba Cloud k8s

With the rapid development and application of cloud computing technology, cloud native technology has become a hot spot for research and application in the field of cloud computing. Among them, container technology and Kubernetes technology have become the most popular and widely used technologies among cloud native technologies. Alibaba Cloud has also launched a complete container cloud service and has emerged as an important player in the development and application of k8s. This article will introduce how to deploy a GitLab application using k8s technology on the Alibaba Cloud Container Service Platform.

1. Why choose to deploy GitLab on k8s

In development, GitLab is a very important version management tool that can coordinate the code development of different team members and improve efficiency and collaboration. Using GitLab can realize code version control, code management, code hosting and other operations, but the traditional way of using GitLab is prone to the following problems:

1. has high requirements on capacity and equipment, and cannot be used very well. Utilize resources;
2. Maintenance costs are high and you need to build your own hardware environment, which poses security risks;
3. The data backup project is large and inconvenient to maintain;
4. Downtime maintenance will affect development User access affects work efficiency.

Therefore, choosing to deploy GitLab on k8s can effectively solve the above problems.

2. Preparation work

Before deploying GitLab on k8s, you need to carry out the following preparation work:

1. Alibaba Cloud Container Service Platform, all operations are performed there performed on the platform.
2. Alibaba Cloud Kubernetes Engine, a Kubernetes engine deployed on Alibaba Cloud Container Service.
3. GitLab image, you can use the image file provided by GitLab official website, or use GitLab image from other trusted sources.

3. Deploy GitLab

After completing the preparation work, you can deploy GitLab, which is mainly divided into the following steps:

1. Installation GitLab

Use helm chart to install GitLab. helm is the official packaging and deployment tool provided by Kubernetes. order

2. Configure GitLab

Configure according to your application, such as domain name, port number, etc.

3. Install GitLab Runner

In Kubernetes, in order to connect the GitLab warehouse and CI/CD Runner, you need to install GitLab Runner.

4. Install the GitLab Kubernetes plug-in

This plug-in allows GitLabCI/CD jobs to run in the Kubernetes environment. Since GitLab Runner directly calls the script in the container to run, so You need to run the container in the Kubernetes environment to execute the job.

5. Configuring GitLab CI/CD

Add Kubernetes as the deployment environment in the CI/CD configuration, and you can pull Docker images, etc. from the Kubernetes cluster.

6. Save the configuration and take effect

After completing all configurations, save the configuration and update it to take effect.

4. Summary

Through Alibaba Cloud Container Service Platform and k8s technology, GitLab applications can be easily deployed, and problems encountered during the deployment process can be effectively solved, such as insufficient resource utilization. , data backup troubles and other issues. Through the k8s cluster environment, GitLab can run faster, more stably, and provide more secure services.
