Image mirroring is the process of copying container images from a source registry to a private registry under your control. This capability is essential for organizations operating in air-gapped environments, restricted networks, or those requiring centralized image governance. The Cortex Cloud Konnector Image Mirroring CLI (kcli) automates this process by pulling multi-architecture konnector images from the Cortex source registry, pushing them to your private registry, and rewriting your Helm values file to reference the mirrored images. This eliminates the need for cluster nodes to access external registries during deployment, reducing attack surface and enabling compliance with network isolation policies. ### Why image mirroring matters * **Network isolation**: Clusters pull images from internal registries only, not from external sources * **Compliance**: Meets requirements for air-gapped deployments and restricted egress policies * **Supply chain control**: Centralize image governance and scanning before deployment * **Deployment reliability**: Eliminates external registry dependencies during cluster operations ### Scope and limitations #### What kcli does * Pulls multi-architecture konnector images from the Cortex source registry * Pushes images to your private registry * Rewrites your Helm values file to reference the mirrored images #### What kcli does not do * Execute `helm install` or `helm upgrade` commands (the portal's installation wizard is the source of truth) * Create Kubernetes Secret resources in your cluster * Manage Namespaces, RBAC, or cluster prerequisites * Commit or push the rewritten values file to Git (GitOps workflows must handle this) * Commit or push the rewritten values file to Git (GitOps workflows must handle this) --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://cortex-docs.paloaltonetworks.com/kubernetes-security/mirror-connector-images-to-a-private-registry.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
