Replace rules are not inherited by consumers of buildx as a module, and as such would default to use the v0.26.2 version. Removing the replace rules also removes various (indirect) dependencies (although brings in some new packages from k8s itself). The "azure" and "gcp" authentication packages in k8s.io/go-client are now no longer functional, so removing those imports. Signed-off-by: Sebastiaan van Stijn <github@gone.nl>

Package auth defines a file format for holding authentication
|
|
information needed by clients of Kubernetes. Typically,
|
|
a Kubernetes cluster will put auth info for the admin in a known
|
|
location when it is created, and will (soon) put it in a known
|
|
location within a Container's file tree for Containers that
|
|
need access to the Kubernetes API.
|
|
|
|
Having a defined format allows:
|
|
- clients to be implemented in multiple languages
|
|
- applications which link clients to be portable across
|
|
clusters with different authentication styles (e.g.
|
|
some may use SSL Client certs, others may not, etc)
|
|
- when the format changes, applications only
|
|
need to update this code.
|
|
|
|
The file format is json, marshalled from a struct authcfg.Info.
|
|
|
|
Client libraries in other languages should use the same format.
|
|
|
|
It is not intended to store general preferences, such as default
|
|
namespace, output options, etc. CLIs (such as kubectl) and UIs should
|
|
develop their own format and may wish to inline the authcfg.Info type.
|
|
|
|
The authcfg.Info is just a file format. It is distinct from
|
|
client.Config which holds options for creating a client.Client.
|
|
Helper functions are provided in this package to fill in a
|
|
client.Client from an authcfg.Info.
|
|
|
|
Example:
|
|
|
|
import (
|
|
"pkg/client"
|
|
"pkg/client/auth"
|
|
)
|
|
|
|
info, err := auth.LoadFromFile(filename)
|
|
if err != nil {
|
|
// handle error
|
|
}
|
|
clientConfig = client.Config{}
|
|
clientConfig.Host = "example.com:4901"
|
|
clientConfig = info.MergeWithConfig()
|
|
client := client.New(clientConfig)
|
|
client.Pods(ns).List()
|
