Requirements for Learning Center in an air-gapped environment

This topic gives you the list of configurations required for Learning Center to properly function in an air-gapped environment.

Learning Center can run in an air-gapped environment but workshops do not have this capability by default. Users must therefore take the following steps to ensure Learning Center functions as expected.

Workshop yaml changes

In an air-gapped environment a user has no Internet access, so workshop yamls should be modified to use:

1. Private container registries.
2. Private Maven, NPM, Python, Go, or any other language repository.

For example, in NPM you can modify the npmrc file to use:

// .npmrc
registry=https://myregistry-url

Self-signed certificates

Air-gapped environments normally use private Certificate Authorities (CA) that may require the use of self-signed certificates. You can allow the injection of CAs by:

1. Setting the env variable NODE_EXTRA_CA_CERTS to the path of the file that contains one or more trusted certificates in PEM format.

2. Add the following to your workshop definition:

   spec:
    session:
      env:
      - name: NODE_EXTRA_CA_CERTS
        value: "$my-cert-pathway"
   

Internet dependencies

If the workshop requires the installation of any Internet dependency, such as a Linux Tool or any other tool, it must be done in the workshop image. See Build an image
