Preparing for an air-gapped installation

To install a self-hosted Instana backend in an environment that is not connected to the internet, ensure that the following prerequisites are met:

1. Configure your image registry to proxy Instana's image registry (artifact-public.instana.io) transparently.
2. List the images that you need to mirror by running the command kubectl instana images. You can pull and push these images to your internal image registry.
3. Point image.registry to your image registry. See the Operator configuration section in this topic.
