Today we had to work on switching between two kubernetes clusters. The commands of the day are:
kubectl config get-contexts
kubectl config use-context <context>
It's surprisingly not so simple. Perhaps there are tools out there that people know of to make it easier? What I've been doing is taking to ~/.kube/config files and concatenating them together. As an example, my config file looks as follows:
apiVersion: v1
clusters:
- cluster:
certificate-authority-data: blahblah...
server: https://172.28.225.133:6443
name: bm
- cluster:
certificate-authority-data: blahblah...
server: https://10.93.140.127:6443
name: ccp
contexts:
- context:
cluster: bm
user: kubernetes-admin
name: bm
- context:
cluster: ccp
user: kubernetes-admin1
name: ccp
current-context: ccp
kind: Config
preferences: {}
users:
- name: kubernetes-admin
user:
client-certificate-data: blahblah...
client-key-data: blahblah...
token: blahblah...
- name: kubernetes-admin1
user:
client-certificate-data: blahblah...
client-key-data: blahblah...
token: blahblah...
Notice how we combine them together. Then I can switch contexts using the commands above. I'll have ccp or bm.
