prometheus/vendor/k8s.io/client-go/CHANGELOG.md

TODO: This document was manually maintained so might be incomplete. The automation effort is tracked in https://github.com/kubernetes/client-go/issues/234.

Changes in k8s.io/api and k8s.io/apimachinery are mentioned here because k8s.io/client-go depends on them.

v7.0.0

Breaking Changes:

• Google Cloud Service Account email addresses can now be used in RBAC Role bindings since the default scopes now include the userinfo.email scope. This is a breaking change if the numeric uniqueIDs of the Google service accounts were being used in RBAC role bindings. The behavior can be overridden by explicitly specifying the scope values as comma-separated string in the users[*].config.scopes field in the KUBECONFIG file.

  • https://github.com/kubernetes/kubernetes/pull/58141

• [k8s.io/api] The ConfigOK node condition has been renamed to KubeletConfigOk.

  • https://github.com/kubernetes/kubernetes/pull/59391

• [k8s.io/api] The PodSecurityPolicy API has been moved to the policy/v1beta1 API group. The PodSecurityPolicy API in the extensions/v1beta1 API group is deprecated and will be removed in a future release.

  • https://github.com/kubernetes/kubernetes/pull/54933

• [k8s.io/api] ConfigMap objects now support binary data via a new binaryData field.

  • https://github.com/kubernetes/kubernetes/pull/57938

• [k8s.io/api] Service account TokenRequest API is added.

  • https://github.com/kubernetes/kubernetes/pull/58027

• [k8s.io/api] FSType is added in CSI volume source to specify filesystems.

• [k8s.io/api] External metric types are added to the HPA API.

  • https://github.com/kubernetes/kubernetes/pull/60096

• [k8s.io/apimachinery] The meta.k8s.io/v1alpha1 objects for retrieving tabular responses from the server (Table) or fetching just the ObjectMeta for an object (as PartialObjectMetadata) are now beta as part of meta.k8s.io/v1beta1. Clients may request alternate representations of normal Kubernetes objects by passing an Accept header like application/json;as=Table;g=meta.k8s.io;v=v1beta1 or application/json;as=PartialObjectMetadata;g=meta.k8s.io;v1=v1beta1. Older servers will ignore this representation or return an error if it is not available. Clients may request fallback to the normal object by adding a non-qualified mime-type to their Accept header like application/json - the server will then respond with either the alternate representation if it is supported or the fallback mime-type which is the normal object response.

  • https://github.com/kubernetes/kubernetes/pull/48991

Bug fixes:

• Use OS-specific libs when computing client User-Agent in kubectl, etc. (https://github.com/kubernetes/kubernetes/pull/44423)
• kubectl commands run inside a pod using a kubeconfig file now use the namespace specified in the kubeconfig file, instead of using the pod namespace. If no kubeconfig file is used, or the kubeconfig does not specify a namespace, the pod namespace is still used as a fallback. (https://github.com/kubernetes/kubernetes/pull/44570)
