Azure Container Agents Plugin

Important: This plug-in is maintained by the Jenkins community and won’t be supported by Microsoft as of February 29, 2024.

Azure Container Agents Plugin can help you to run a container instance as an agent in Jenkins

How to install

You can install/update this plugin in Jenkins update center (Manage Jenkins -> Manage Plugins, search Azure Container Agents Plugin).

Pre-requirements

Azure Container Instance

Azure Container Instances offers the fastest and simplest way to run a container in Azure, without having to provision any virtual machines and without having to adopt a higher-level service.

Pre-requirements

Configure the plugin

  1. Jenkins -> Manage Jenkins -> Configure System
  2. Press Add a new cloud and choose Azure Container Instance
  3. Specify Cloud Name and it should be unique.
  4. Choose an existing Azure Credential or create a new credential.
  5. Choose Resource Group.

Configure the Container Template

  1. Specify Name and Labels
  2. Set Startup Timeout.
  3. Select Image OS Type, Windows or Linux.
  4. Fill in Docker Image. The default image is jenkins/inbound-agent and you can also use it as base image.
  5. If you use a private registry, you need to specify a credential.
  6. Specify a Command. Now the Command will override the ENTRYPOINT. Arguments. ${rootUrl}, ${secret}, ${instanceIdentity} and ${nodeName} will be replaced with JenkinsUrl, Secret, Instance identity and ComputerNodeName automatically.
  7. Specify the Working Dir. Ensure the user has write permission to this directory.
  8. Add Ports, Environment Variables and Volumes as needed.
  9. Choose a retention strategy. You can get details by clicking the help icon.
  10. Specify CPU Requirement and Memory Requirement, ACI containers costs per second. Find more details in Container Instances pricing.
  11. Decide if the container instance should use a private IP address or not. You can get details by clicking the help icon.

Configure Azure Container Instance via Groovy Script

You can use the sample below in Manage Jenkins -> Script Console. The sample only contains a few arguments. Find all the arguments in the builders package.

import com.microsoft.jenkins.containeragents.builders.*

def myCloud = new AciCloudBuilder()
.withCloudName("mycloud")
.withAzureCredentialsId("<Your Credentials Id>")
.withResourceGroup("myResourceGroup")
.addNewTemplate()
    .withName("mytemplate")
    .withLabel("aci")
    .addNewPort("80")
    .addNewEnvVar("key","value")
.endTemplate()
.build()

Jenkins.get().clouds.add(myCloud)
//inherit template from existing template
import com.microsoft.jenkins.containeragents.builders.*

def baseTemplate = new AciContainerTemplateBuilder()
.withImage("privateImage")
.addNewPort("80")
.addNewEnvVar("key", "value")
.build()

def myCloud = new AciCloudBuilder()
.withCloudName("mycloud")
.withAzureCredentialsId("<Your Credentials Id>")
.withResourceGroup("myResourceGroup")
.addNewTemplateLike(baseTemplate)
    .withName("mytemplate")
    .withLabel("aci")
.endTemplate()
.build()

Jenkins.get().clouds.add(myCloud)

Azure Kubernetes Service

If you were previously using this plugin to integrate with AKS you should use the Kubernetes plugin instead.
