From: Sylvain Desbureaux Date: Tue, 16 Mar 2021 13:09:29 +0000 (+0100) Subject: Provide support for air gapped env for rally X-Git-Url: https://gerrit.opnfv.org/gerrit/gitweb?a=commitdiff_plain;h=refs%2Fchanges%2F62%2F72162%2F4;p=functest-kubernetes.git Provide support for air gapped env for rally Sometimes, tested Kubernetes doesn't have direct access to Internet but access through repository mirrors. This patch handles this case for rally test case. There's two ways for providing the repository mirrors: - Give an environment variable (`MIRROR_REPO`) which gives a repository mirro with all needed images. - Gives an environment variable per needed repo: - `DOCKERHUB_REPO` for DockerHub repository (`docker.io`) - `GCR_REPO` for Google Cloud repository (`gcr.io`) - `K8S_GCR_REPO` for Kubernetes repository (`k8s.gcr.io`) Needed images list has also been extracted so Kubernetes administrator can easily upload these images to the mirror if the mirror also doesn't have access to Internet.
