Etcd helper

A helper tool for getting OpenShift/Kubernetes data directly from Etcd.

This is a copy of https://github.com/openshift/origin/tree/master/tools/etcdhelper with following changes:

• get - will output the resource as yaml
• dump - will save the entire contents of etcd to individual yaml files

How to build

$ go build .

Basic Usage

This requires setting the following flags:

• -key - points to master.etcd-client.key
• -cert - points to master.etcd-client.crt
• -cacert - points to ca.crt

Once these are set properly, one can invoke the following actions:

• ls - list all keys starting with prefix
• get - get the specific value of a key
• dump - save the entire contents of etcd to individual files

Sample Usage

List all keys starting with /openshift.io:

etcdhelper -key master.etcd-client.key -cert master.etcd-client.crt -cacert ca.crt ls /openshift.io

Get YAML-representation of imagestream/python from openshift namespace:

etcdhelper -key master.etcd-client.key -cert master.etcd-client.crt -cacert ca.crt get /openshift.io/imagestreams/openshift/python

Dump the contents of etcd to yaml files:

etcdhelper -key master.etcd-client.key -cert master.etcd-client.crt -cacert ca.crt dump
