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

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.

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

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.

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>

Start a Gradle workspace.
Open a new terminal in the tools container.
Run ~/init-truststore.sh.

Results

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