kubectl-eksporter

A simple Ruby-script to export k8s resources, and removes a pre-defined set of fields for later import

Usage

kubectl eksporter <resource> <name>

-n / --namespace and other arguments are supported by proxy.

The eksporter also supports piping.

Command arguments

--drop

You can easily remove more fields with the --drop argument. List the fields (also nested fields) to be removed.

--keep

If you need some of the pre-defined fields, you can list them with --keep and they will not be removed.

Example

$ kubectl eksporter ingress testapp
---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  labels:
    app: testapp
    environment: default
  name: testapp
spec:
  rules:
  - host: testapp.local
    http:
      paths:
      - backend:
          serviceName: testapp
          servicePort: 80
        path: "/"

The following command wil give the same result.

$ kubectl get ingress testapp -o yaml | kubectl eksporter

Install

First you need install Krew, by following the installation guide.

Then just run kubectl krew install eksporter

Why Ruby?

Python didn't have a built-in yaml-converter, and Go is a hassle to work with when you need generic data structures.

Release

1. Make changes to the code
2. Tag with git tag -a v1.3.0
3. New release is automated created and pushed to Krew
