Using Contexts

Merge Multi Config

./k8c merge [new-config] [config-1] [config-2] ... [config-n]
---
eg: (merge into single file $HOME/.kube/config)

./k8c merge $HOME/.kube/config  $HOME/.kube/config-staging-dev $HOME/.kube/config-staging-uat $HOME/.kube/config-staging-qa

Discovery All KUBECONFIG Files Inside ~/.kube Folder --- Interactive Mode

./k8c load
---
Select a kubeconfig file:  [Use arrows to move, type to filter]
> /home/devopscorner/.kube/.switch_tmp/config.1072356766.tmp
/home/devopscorner/.kube/.switch_tmp/config.3841581520.tmp

Available Kubernetes contexts:
arn:aws:eks:ap-southeast-1:YOUR_AWS_ACCOUNT:cluster/devopscorner-lab
arn:aws:eks:ap-southeast-1:YOUR_AWS_ACCOUNT:cluster/devopscorner-dev-staging
arn:aws:eks:ap-southeast-1:YOUR_AWS_ACCOUNT:cluster/devopscorner-uat-staging
arn:aws:eks:ap-southeast-1:YOUR_AWS_ACCOUNT:cluster/devopscorner-production

List Context(s)

KUBECONFIG=$HOME/.kube/config
kubectl config get-contexts

-- or --

## Default KUBECONFIG path (`/.kube/config`) ##
./k8c list
---
arn:aws:eks:ap-southeast-1:YOUR_AWS_ACCOUNT:cluster/devopscorner-lab

## Spesific Kubeconfig ##
./k8c list -f $HOME/.kube/config-cluster
---
Available Kubernetes contexts:
arn:aws:eks:ap-southeast-1:YOUR_AWS_ACCOUNT:cluster/devopscorner-dev-staging
arn:aws:eks:ap-southeast-1:YOUR_AWS_ACCOUNT:cluster/devopscorner-uat-staging

Switch (select) Context(s) --- Interactive Mode

## Default KUBECONFIG path (`/.kube/config`) ##
./k8c switch
---
? Select a context  [Use arrows to move, type to filter]
> arn:aws:eks:ap-southeast-1:YOUR_AWS_ACCOUNT:cluster/devopscorner-lab

> Changed context to: arn:aws:eks:ap-southeast-1:YOUR_AWS_ACCOUNT:cluster/devopscorner-dev-staging

## Spesific Kubeconfig ##
./k8c switch - $HOME/.kube/config-cluster
---
? Select a context  [Use arrows to move, type to filter]
> arn:aws:eks:ap-southeast-1:YOUR_AWS_ACCOUNT:cluster/devopscorner-dev-staging
arn:aws:eks:ap-southeast-1:YOUR_AWS_ACCOUNT:cluster/devopscorfner-uat-staging

> Changed context to: arn:aws:eks:ap-southeast-1:YOUR_AWS_ACCOUNT:cluster/devopscorner-dev-staging

Run Spesific KUBECONFIG

KUBECONFIG=$HOME/.kube/config-new-cluster
kubectl config use [cluster_name]

-- or --

./k8c switch -f $HOME/.kube/config-new-cluster
