Installation of agent relay in an air-gapped environment

An air-gapped environment is a network or system isolated from the public internet, typically for security or compliance reasons. In such environments, you must import all external resources manually. Deploy supports air-gapped installations by providing scripts and configurations to transfer required resources into your private environment.

Some deployments operate without internet access, requiring all container images, plugins, and dependencies to be preloaded into a private registry.

Scripts and configurations for air-gapped installation

Deploy provides the airgap.sh script along with Helm configuration parameters to support air-gapped setups.
Parameter Description Example value
global.imageRegistry Private registry for product images registry.local:5000/devops-deploy
global.externalImageRegistry Private registry for unqualified/public images. The airgap.sh script places qualified and unqualified images in the same image repository, and you can separate them if required. registry.local:5000/public
airgap.sh Script to list or copy required images to the private registry ./airgap.sh -|

The airgap.sh script provides the following capabilities:

  • Lists all the container images required by Deploy (using the -l option).
  • Copies images from public registries to a private or internal registry.
