Running a Build Task on a Custom Environment (Built-in Executors, GUI)

Scenario

You may need to extend CodeArts Build with custom environments in the following scenarios:

• CodeArts Build uses Java 1.8 by default, but you may require Java 21.

• Your build may require your enterprise's dedicated tools that are not supported by CodeArts Build.

In this practice, you customize a build environment to run a build task.

Requirements

• You have created an organization named hwstaff_codeci_gray in SWR.
  • You have permissions for CodeArts Artifact.
  • You have permissions for CodeArts Repo.

Procedure

Creating a Project

1. Log in to the Huawei Cloud console with your Huawei Cloud account.
2. Click in the upper left corner and choose Developer Services > CodeArts from the service list.
3. Click Access Service. The homepage of CodeArts is displayed.
4. Click Create Project, and select the Scrum template.
5. Set the project name to build-bestpractice, and leave the other parameters as default.
6. Click OK to access the project.

Creating a CodeArts Repo Repository

1. In the navigation pane, choose Code > Repo.
2. On the displayed page, click New Repository. Select Template, and click Next.
3. On the template selection page, select the Java Maven Demo template and click Next.
4. On the displayed page, set Repository Name to custom_env_repo, and leave the other parameters as default. Click OK. The details page of the new code repository is displayed.
5. In the root directory of the code repository, choose Create and select Create File from the drop-down list.

6. Name the file Dockerfile, copy the following code to the file, and click Submit.

   FROM ubuntu:latest
   
   # set maintainer
   LABEL maintainer=custom_image
   
   RUN apt-get update && apt-get install -y wget 
   
   RUN mkdir /usr/java && \
     cd /usr/java && \
     wget "https://download.oracle.com/java/17/latest/jdk-17_linux-x64_bin.tar.gz" && \
     tar -xvf jdk-17_linux-x64_bin.tar.gz && \
     rm -rf jdk-17_linux-x64_bin.tar.gz
   
   RUN mkdir /usr/maven && \
     cd /usr/maven && \
     wget "https://dlcdn.apache.org/maven/maven-3/3.9.8/binaries/apache-maven-3.9.8-bin.tar.gz" && \
     tar -xvf apache-maven-3.9.8-bin.tar.gz && \
     rm -rf apache-maven-3.9.8-bin.tar.gz
   
   ENV JAVA_HOME /usr/java/jdk-17.0.12
   ENV MAVEN_HOME /usr/maven/apache-maven-3.9.8
   ENV PATH $PATH:$JAVA_HOME/bin:$MAVEN_HOME/bin
   
   RUN java -version && mvn -v
   
   USER build
   Figure 2 Dockerfile content
   

   Dockerfile contains the following instructions for building a container image as your custom environment.

   Table 2 Dockerfile instructions

   Instruction	Description
   FROM	It specifies the base image (the latest official Ubuntu image is used in this practice) and must be the first instruction.
   LABEL	It adds metadata to an image.
   RUN	They are run when docker build creates an image. In this practice, RUN instructions install three tools: Wget, Java Development Kit (JDK) 17, and Maven 3.9.8. After environment variables are set, these instructions run commands to verify the installation of proper JDK and Maven versions.
   ENV	They set environment variables. In this practice, ENV instructions set environment variables for JDK and Maven and add their directory to the PATH environment variable so that users can conveniently run JDK and Maven by invoking shortcut commands.
   USER	It sets the user when the container is run. In this practice, the build user is set for the container runtime.

Creating an Image as the Custom Build Environment

1. In the navigation pane, choose CICD > Build.
2. Click Create Task. On the displayed Basic Information page, set parameters according to Table 3. Then, click Next.

   Table 3 Basic information

   Parameter	Description
   Name	Assign a custom name to the build task, for example, custom_env_task.
   Code Source	Select the code source from which code will be pulled for your build. In this practice, select Repo.
   Repository	Select custom_env_repo, the code repository created in Creating a CodeArts Repo Repository.
   Default Branch	Keep the default value master.

3. Select Blank Template and click OK to create the build task. The Build Actions page is displayed.
4. On the Build Actions page, click the GUI tab and click Add Build Actions.
   Figure 3 Adding a build action
   

5. In the right pane, click the Container related tab. Hover over action Build Image and Push to SWR and click Add on the card. Set the parameters according to Figure 4. Expand the Organization drop-down list and select hwstaff_codeci_gray created to meet the requirements. Type custom_ubuntu_image in the Image Name text box, and v1.0 in Image Tag. Leave the other parameters as default.

6. Click Save and Run in the upper right corner. In the displayed dialog box, click Confirm. The build task run page is displayed.
7. On the Actions tab, check that the console displays the logs of the build task as it runs. The Build Logs window automatically scrolls down to show new entries. As shown in Figure 5, the console prints logs of creating an image from the Dockerfile stored in the code repository.

8. After the build task is successfully run, go to the SWR console. Choose My Images and click the Private Images tab (which is displayed by default). From there, click the name of the image (custom_ubuntu_image) created in 5 to access its details page.
9. On the image details page, click Edit. In the displayed dialog box, set Type to Public and click OK.
