clientgofix rewrites calls to old k8s.io/client-go methods to use newer invocations

clientgofix is a tool for adjusting k8s.io/client-go invocations for k8s.io/client-go v0.18.0+ versions. It can be run on a codebase before or after updating the k8s.io/client-go dependency.

See https://git.k8s.io/enhancements/keps/sig-api-machinery/20200123-client-go-ctx.md for more context.

⚠️ This tool is under active development and rewrites source files in place by default. It is strongly recommended to run this on a version-controlled source tree with all unrelated work committed.

Automatic adjustments:

• Inserts a context.TODO() argument where required
• Inserts an empty options struct argument where required (like metav1.UpdateOptions{})
• Dereferences existing *metav1.DeleteOptions arguments
• Replaces existing nil *metav1.DeleteOptions arguments with metav1.DeleteOptions{}
• Adds context and metav1 imports where required (deconflicting with existing import and declaration names)

Manual adjustments required:

• Context parameters passed to rest.Request#Context must be manually moved to the request Do() invocation.

To install:

git clone https://github.com/kubernetes-sigs/clientgofix.git
cd clientgofix
make install

To use:

cd /path/to/project
clientgofix ./pkg/to/fix

Options:

• Multiple packages or a recursive package spec can be provided:

  • clientgofix ./pkg1 ./pkg2
  • clientgofix ./...

• Files are rewritten in place by default. Set -overwrite=false to write to peer tmp files.

• If errors are encountered processing a file, writing is skipped by default. Set -write-on-error=true to write the file even when errors are encountered.
