We have a Git repository where we have a file config gs. This file has been modified in the last two commits, but those two commits introduced a bug. We need to restore config gs to the version that it had two commits ago while not affecting any other file. Run Git log to see last five commits. Next, we'll preview config gs that was two commits ago, for this we'll type git show head meaning our current last commit and then the sign, and then two. Next, we'll type git checkout head tilde sign two and then two hyphens config gs, which will restore config gs that was two commits ago. Last thing, we need to commit our changes with restore config gs message.

We have a question with custom resource definition schema validation. The custom resource definition is called widgets. In Kubernetes we can create custom resources with specific APIs. This resource has been created in extensions namespace. If we do kubectl apply F bad widget, the widget will be created without any validation. The spec is empty, but nevertheless it has been applied, which according to our question crashes our controller. We need to apply a strict validation that requires spec size. It has to be integer and minimum value has to be one. We'll do this by editing the custom resource definition schema, and that's done by kubectl edit CRD, and then the name of the resource. We need to find the schema section. We'll have same openAPIV3schema field type object. And properties will be, instead of empty spec, we'll have object type required size. Reapply our bad widget yaml. We get a validation error that widget bad widget is invalid, requires value.
