Kubernetes Secrets in plain-text

I’ve seen some elaborate solutions to easily retrieve Kubernetes secrets in plain-text. This is what I came up with to make my life easier.

Prerequisites#

$ brew install jq

Installation#

Create a file (e.g. ~/.shellfn) containing the following shell function:

function ksecret () {
  kubectl get secrets $@ -ojson | jq '{name: .metadata.name, data: .data | map_values(@base64d)}'
}

Include the file in your .zshrc, .bashrc, etc. or just via your CLI source ~/.shellfn.

Usage#

$ ksecret -n my-namespace the-secret

Output:

{
  "name": "the-secret",
  "data": {
    "foo": "something in plain-text",
    "bar": "more something in plain-text"
  }
}

Use with with pbcopy or jq for additional convenience, e.g.

$ ksecret -n my-namespace the-secret | pbcopy
