Automatic merge from submit-queue (batch tested with PRs 48812, 48276) client-go support IPv6 addresses for PortForwarder getListener() Currently, client-go requires that an IPv6 address string for hostname has square brackets surrounding, so that it can be used with address:port in an API request. This change, removes that requirement, and has getListener() add the square brackets, if needed. If the hostname is a name, an IPv4 address string, or an IPv6 address already with square brackets, no change is made. Decided to change here, rather than everywhere client-go is used (thinking that there may be places where we DON'T want the square brackets applied). This issue was found in kubelet, which, at startup, creates a listener for services and nodes. If an IPv6 address is used, the URI was malformed. **What this PR does / why we need it**: Ensures that client-go will handle IPv6 addresses as hostnames, without any special encoding by caller. **Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #48225 **Special notes for your reviewer**: **Release note**: ```release-note NONE ```
This directory is the staging area for packages that have been split to their own repository. The content here will be periodically published to respective top-level k8s.io repositories.
Most code in the staging/ directory is authoritative, i.e. the only copy of
the code. You can directly modify such code. However the packages in
staging/src/k8s.io/client-go/pkg are copied from pkg/. If you modify the
original code in pkg/, you need to run hack/godep-restore.sh from the k8s
root directory, followed by hack/update-staging-client-go.sh. We are working
towards making all code in staging/ authoritative.
The vendor/k8s.io directory contains symlinks pointing to this staging area,
so to use a package in the staging area, you can import it as
k8s.io/<package-name>, as if the package were vendored. Packages will be
vendored from k8s.io/<package-name> for real after the test matrix is
converted to vendor k8s components.
