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

You have an active oc session with your project. See This page is not included, but the link has been rewritten to point to the nearest parent document.Getting started with the CLI.
You know the URL of your Go module proxy.

Procedure

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.

Apply the Secret to your project:
```
$ oc apply -f tls-cert.yaml -n <your_namespace>
```
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.
Apply the ConfigMap to your project:
```
$ oc apply -f go-config.yaml -n <your_namespace>
```
Start or restart your workspace.

Results

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