   kubectl node-pod
   

How to release

See https://goreleaser.com/quick-start/

Set up a github token and run:

git push --tags

export GITHUB_TOKEN=...

goreleaser

In the plugin.yaml file:

• manually update the sha256's using the checksums file
  • TODO is there a better way to do this?
• manually update the versions using the checksums file
  • TODO is there a better way to do this?

How to test a local krew release

1. Choose one of the following:

   • easy way: kubectl krew install --manifest=./deploy/krew/node-pod.yaml

   • hard way:

     1. download a binary from the github project release page

     2. run a krew install against the downloaded binary

        kubectl krew install --manifest=./deploy/krew/node-pod.yaml --archive=/Users/mfenwick/Downloads/node-pod_darwin_amd64.tar.gz
        

2. test it

   kubectl node-pod
   

3. clean up

   kubectl krew uninstall node-pod
