Set up Gradle to use your internal registry

Set up Gradle so that Gradle workspaces can download plugins and dependencies from your internal registry. .Prerequisites

About this task

  • You are not running any Gradle workspace.

Procedure

  1. Create a Secret to store the TLS certificate: 
    kind: Secret
apiVersion: v1
metadata:
  name: tls-cer
  annotations:
    controller.devfile.io/mount-path: /home/user/certs
    controller.devfile.io/mount-as: file
  labels:
    controller.devfile.io/mount-to-devworkspace: 'true'
    controller.devfile.io/watch-secret: 'true'
data:
  tls.cer: >-
    <Base64_encoded_content_of_public_cert>

    where:

    <Base64_encoded_content_of_public_cert>
    The Base64-encoded content of your Gradle artifact repository’s public TLS certificate, with line wrapping disabled.
  2. Create a ConfigMap for the TrustStore initialization script: 
    kind: ConfigMap
apiVersion: v1
metadata:
  name: init-truststore
  annotations:
    controller.devfile.io/mount-as: subpath
    controller.devfile.io/mount-path: /home/user/
  labels:
    controller.devfile.io/mount-to-devworkspace: 'true'
    controller.devfile.io/watch-configmap: 'true'
data:
  init-truststore.sh: |
    #!/usr/bin/env bash

    keytool -importcert -noprompt -file /home/user/certs/tls.cer -cacerts -storepass changeit
  3. Create a ConfigMap for the Gradle init script: 
    kind: ConfigMap
apiVersion: v1
metadata:
  name: init-gradle
  annotations:
    controller.devfile.io/mount-as: subpath
    controller.devfile.io/mount-path: /home/user/.gradle
  labels:
    controller.devfile.io/mount-to-devworkspace: 'true'
    controller.devfile.io/watch-configmap: 'true'
data:
  init.gradle: |
    allprojects {
      repositories {
        mavenLocal ()
        maven {
          url "https://<gradle_artifact_repository_route>/repository/maven-public/"
          credentials {
            username "admin"
            password "passwd"
          }
        }
      }
    }

    where:

    <gradle_artifact_repository_route>
    The hostname and path of your internal Gradle artifact repository.
  4. Apply the Secret and both ConfigMaps to your project: 
    $ oc apply -f tls-cer.yaml -n <your_namespace>
$ oc apply -f init-truststore.yaml -n <your_namespace>
$ oc apply -f init-gradle.yaml -n <your_namespace>
  5. Start a Gradle workspace.
  6. Open a new terminal in the tools container.
  7. Run ~/init-truststore.sh.

Results

  1. In the workspace terminal, build a Gradle project to verify artifact resolution from the mirror: 
    $ gradle build
