Using NuGet artifact repositories

To configure NuGet in a restricted environment, modify the nuget.config file and use the SSL_CERT_FILE environment variable in the devfile to add self-signed certificates.

Configuring NuGet to use a non-standard artifact repository

NuGet searches for configuration files anywhere between the solution directory and the driver root directory. If you put the nuget.config file in the /projects directory, the nuget.config file defines NuGet behavior for all projects in /projects.

Procedure

Create and place the nuget.config file in the /projects directory.

Example nuget.config with a Nexus repository hosted at nexus.example.org:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <packageSources>
    <add key="nexus2" value="https://nexus.example.org/repository/nuget-hosted/"/>
  </packageSources>
  <packageSourceCredentials>
    <nexus2>
        <add key="Username" value="user" />
        <add key="Password" value="..." />
    </nexus2>
  </packageSourceCredentials>
</configuration>

Using self-signed certificates in NuGet projects

Internal artifact repositories often do not have a self-signed TLS certificate signed by an authority that is trusted by default. They are usually signed by an internal company authority or are self-signed. Configure your tools to accept these certificates.

Procedure

Obtain the certificate file of a non-standard repository and place it in the /projects/tls/rootCA.crt file to make it accessible from all your containers.

Specify the location of the certificate file in the SSL_CERT_FILE environment variable in your devfile for the OmniSharp plug-in and for the .NET container.

Example of the devfile:

components:
  - id: redhat-developer/che-omnisharp-plugin/latest
    memoryLimit: 1024Mi
    type: chePlugin
    alias: omnisharp
    env:
     - value: /projects/tls/rootCA.crt
       name: SSL_CERT_FILE
 - mountSources: true
   endpoints:
     - name: 5000/tcp
       port: 5000
   memoryLimit: 512Mi
   type: dockerimage
   volumes:
     - name: dotnet
       containerPath: /home/user
   alias: dotnet
   image: 'quay.io/eclipse/che-dotnet-2.2:7.7.1'
   env:
     - value: /projects/tls/rootCA.crt
       name: SSL_CERT_FILE
