The product of this work was moved into
https://github.com/skupperproject/skupper/tree/main/test/images
The Makefile on this directory allows for the manipulation of container images pertaining to external test dependencies, such as Mongo or iperf.
It contains three operations: the first exists to avoid the Dockerhub pull limit, and also to allow for testing on disconnected clusters. It simply copies the images from their original locations into our Quay repo.
The second operation was created in response to an image used by our tests that stopped getting updates, while the actual project continued to evolve. It builds images from Dockerfile and pushes them into our Quay repo.
Finally, the third one also allows for the running of tests on disconnected clusters, which cannot access the original locations of these dependencies to download them (as they have no external Internet access). The operation allows for copying the list of images from our Quay repo into another repo.
This allows for the test dependencies to be copied to the disconnected cluster's local repository, from where the cluster can access them. Additional configuration will be required on the cluster (such as creating an MCO to re-route the image pull requests), but that's out of the scope of this document.
Note that this is not a full repo copy; it's restricted to the list of images contained on the Makefile. Skupper images (such as the router or controller) are not copied by this operation.
See the Makefile contents for information on how to execute the different operations.
Note that the skupper-test image used by Skupper integration
is part of Skupper's own test code, so it's build by the main
Makefile at https://github.com/skupperproject/skupper, and not here.
