Must-gathers are standardized images that allows an administrator to collect all the relevant resources from a cluster into a single directory. This benefits operators like Dev Spaces specifically, since it means a single command can be used to collect and inspect all of the resources at once, rather than in piecemeal commands or separate collections.

Examples of other operators that supply must-gather images include OpenShift GitOps and OpenShift Pipelines, both of which come up just as frequently as Dev Spaces.

I’ve mocked up a functioning must-gather image (GitHub) that can be used right now via

oc adm must-gather --image quay.io/rhn_support_jorbell/dev-spaces-must-gather:latest

for testing. I’ve confirmed that it pulls in all the expected resources, e.g. CheCluster and DevWorkspaceOperatorConfig, as well as the OLM resources such as the Subscription and ClusterServiceVersion for both Dev Spaces and DevWorkspace operators.

Including this image into the official dev cycle for Dev Spaces should increase the agility of resource collection at the very least.
