The "// import <path>" comment has been superseded by Go modules.
We don't have to remove them, but doing so has some advantages:
- They are used inconsistently, which is confusing.
- We can then also remove the (currently broken) hack/update-vanity-imports.sh.
- Last but not least, it would be a first step towards avoiding the k8s.io domain.
This commit was generated with
sed -i -e 's;^package \(.*\) // import.*;package \1;' $(git grep -l '^package.*// import' | grep -v 'vendor/')
Everything was included, except for
package labels // import k8s.io/kubernetes/pkg/util/labels
because that package is marked as "read-only".
Previously, ValidateNodeSelector did not check that labels are valid. Now it
does for resource.k8s.io, regardless whether an object already was created with
invalid labels in an earlier Kubernetes release. Theoretically this is a
breaking change and could cause problems during an upgrade, but that is highly
unlikely in practice.
In contrast to node affinity, DRA does not ignore parse errors
(= uses NewNodeSelector, not NewLazyErrorNodeSelector), so invalid labels would
have been found instead of being silently ignored.
Even if some object has invalid labels, this only affects an alpha -> beta
upgrade which isn't guaranteed to work seamlessly.
1. The effective container requests cannot be greater than pod-level requests
2. Inidividual container limits cannot be greater than pod-level limits
3. Only CPU & Memory are supported at pod-level
4. Inplace container resources updates are not supported if pod-level resources are set
Note: effective container requests cannot be greater than pod-level limits is supported by transitivity. Effective container requests <= pod-level requests && pod-level requests <= pod-level limits; Therefore effective container requests <= pod-level limits

1. If pod-level limit is set, pod-level request is unset and container-level request is set: derive pod-level request from container-level requests
2. If pod-level limit is set, pod-level request is unset and container-level request is unset: set pod-level request equal to pod-level limit
