Set up NuGet to use your internal registry

Set up NuGet so that .NET workspaces can restore packages from your internal NuGet feed. .Prerequisites

About this task

You are not running any NuGet workspace.
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.

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 NuGet artifact repository’s public TLS certificate, with line wrapping disabled.

Apply the Secret to your project:
```
$ oc apply -f tls-cer.yaml -n <your_namespace>
```

Create a ConfigMap to set the SSL_CERT_FILE environment variable to the path of the TLS certificate:

kind: ConfigMap
apiVersion: v1
metadata:
  name: disconnected-env
  annotations:
    controller.devfile.io/mount-as: env
  labels:
    controller.devfile.io/mount-to-devworkspace: 'true'
    controller.devfile.io/watch-configmap: 'true'
data:
  SSL_CERT_FILE: /home/user/certs/tls.cer

Create a ConfigMap for the nuget.config file:

kind: ConfigMap
apiVersion: v1
metadata:
  name: init-nuget
  annotations:
    controller.devfile.io/mount-as: subpath
    controller.devfile.io/mount-path: /projects
  labels:
    controller.devfile.io/mount-to-devworkspace: 'true'
    controller.devfile.io/watch-configmap: 'true'
data:
  nuget.config: |
    <?xml version="1.0" encoding="UTF-8"?>
    <configuration>
      <packageSources>
        <add key="nexus2" value="https://<nuget_artifact_repository_route>/repository/nuget-group/"/>
      </packageSources>
      <packageSourceCredentials>
        <nexus2>
            <add key="Username" value="admin" />
            <add key="Password" value="passwd" />
        </nexus2>
      </packageSourceCredentials>
    </configuration>

where:

<nuget_artifact_repository_route>: The hostname and path of your internal NuGet artifact repository.

Apply both ConfigMaps to your project:

$ oc apply -f disconnected-env.yaml -n <your_namespace>
$ oc apply -f init-nuget.yaml -n <your_namespace>

Start a NuGet workspace.

Results

Open a terminal in your workspace.
Verify the NuGet source configuration:
```
$ dotnet nuget list source
```
The output includes the artifact repository URL from your nuget.config ConfigMap.
Restore packages to verify artifact resolution from the mirror:
```
$ dotnet restore
```
