Installation of DevOps Loop 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, all external resources must be imported manually. DevOps Loop 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

DevOps Loop provides the airgap.sh script along with Helm configuration parameters to support air-gapped setups.
