Set up Go to use your internal registry

Set up Go to use a module proxy by setting environment variables in your workspaces. .Prerequisites

About this task

Procedure

  1. Create a Secret to store the TLS certificate: 
    kind: Secret
apiVersion: v1
metadata:
  name: tls-cert
  labels:
    controller.devfile.io/mount-to-devworkspace: 'true'
    controller.devfile.io/watch-secret: 'true'
  annotations:
    controller.devfile.io/mount-path: /home/user/certs
    controller.devfile.io/mount-as: file
type: Opaque
data:
  tls.cer: >-
    <Base64_encoded_TLS_certificate>

    where:

    <Base64_encoded_TLS_certificate>
    The Base64-encoded content of your Go module proxy’s TLS certificate.
  2. Apply the Secret to your project: 
    $ oc apply -f tls-cert.yaml -n <your_namespace>
  3. Create a ConfigMap with Go environment variables:
    Warning

    Applying a ConfigMap that sets environment variables might cause a workspace boot loop. If you encounter this behavior, remove the ConfigMap and edit the devfile directly.

     
    kind: ConfigMap
apiVersion: v1
metadata:
  name: go-config
  labels:
    controller.devfile.io/mount-to-devworkspace: 'true'
    controller.devfile.io/watch-configmap: 'true'
  annotations:
    controller.devfile.io/mount-as: env
data:
  GOPROXY: <your_go_proxy_url>
  GONOSUMDB: "*"
  GOPRIVATE: "<your_private_modules>"
  SSL_CERT_FILE: /home/user/certs/tls.cer

    where:

    <your_go_proxy_url>
    The URL of your internal Go module proxy.
    <your_private_modules>
    A comma-separated list of Go module path prefixes for private modules that bypass the proxy and checksum database.
  4. Apply the ConfigMap to your project: 
    $ oc apply -f go-config.yaml -n <your_namespace>
  5. Start or restart your workspace.

Results

  1. Open a terminal in your workspace.
  2. Verify the Go configuration: 
    $ go env GOPROXY
  3. Download a Go module to verify the configuration: 
    $ go get github.com/gin-gonic/gin
