Solution Overview

This solution helps you quickly deploy source code compilation environments on Elastic Cloud Server (ECS). With the elastic scaling of ECS and the persistency of Jenkins, this solution helps you quickly and inexpensively deploy complex compilation environments, greatly improving the efficiency of software deployment. Jenkins is an open-source continuous integration tool written in Java. It aims to provide an open and easy-to-use software platform for continuous integration of software projects. Gerrit is a web-based code review tool built on top of the git version control system. It aims to provide a lightweight framework for reviewing every commit before it is accepted into the code base.

Architecture

Architecture Description

This solution will:

1. Create two ECSs, one for the Gerrit code repository and one for the Jenkins master node.
2. Configure compilation nodes and configure Huawei Cloud plug-ins on the Jenkins master node to dynamically create and release ECS compilation nodes.
3. Create an Object Storage Service (OBS) bucket to store compilation results.

You can use Image Management Service (IMS) to prepare the OS environment required for compilation in advance.

Getting Started

Accessing Gerrit and Creating a Code Repository

1. On the Outputs tab of the stack, copy the Gerrit access address.

   Figure 1 Gerrit access address

2. Paste the Gerrit access address to the address bar of a browser and click Sign in.

Accessing Jenkins

1. In the ECS list on the Elastic Cloud Server (ECS) console, click the created Jenkins server.

   Figure 7 Accessing the Jenkins server

2. Click Remote Login. In the displayed dialog box, click Log In in the CloudShell-based Login area.

3. After the connection is set up, run cat /app/jenkins_home/secrets/initialAdminPassword to obtain the login password of user admin and copy the password.

4. On the Outputs tab of the stack, obtain the Jenkins access address.

5. Configure the HuaweiCloud ECS plugin to automatically create Huawei Cloud ECSs as the slave nodes of the Jenkins cluster.
