Linode CLI

At the time of this video there is not docker image for Linode CLI, so lets make our own :)
Take a look at the dockerfile in this folder.

# Linode CLI

# Run this from the root of the repo!

docker run -it --rm -v ${PWD}:/work -w /work --entrypoint /bin/bash aimvector/linode:2.15.0
cd ./kubernetes/cloud/linode

Login to Linode

#login and follow prompts
linode-cli

Gather our options

https://www.linode.com/docs/platform/api/linode-cli/

linode-cli lke --help

linode-cli regions list --text
linode-cli lke versions-list 
linode-cli linodes list --region ap-south

Create our cluster

# full list of options
linode-cli lke cluster-create --help

Get a kubeconfig for our cluster

linode-cli lke clusters-list

linode-cli lke kubeconfig-view <id>

Download a kubeconfig from the dashboard
Rename and drop it into ./kubernetes/cloud/linode/config.yaml

Get kubectl

curl -LO https://storage.googleapis.com/kubernetes-release/release/`curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt`/bin/linux/amd64/kubectl
chmod +x ./kubectl
mv ./kubectl /usr/local/bin/kubectl

export KUBECONFIG=/work/kubernetes/cloud/linode/config.yaml

kubectl create ns example-app

# lets create some resources.
kubectl apply -n example-app -f /work/kubernetes/secrets/secret.yaml
kubectl apply -n example-app -f /work/kubernetes/configmaps/configmap.yaml
kubectl apply -n example-app -f /work/kubernetes/deployments/deployment.yaml

# remember to change the `type: LoadBalancer`
kubectl apply -n example-app -f /work/kubernetes/services/service.yaml

Clean up

linode-cli lke clusters-list
linode-cli lke cluster-delete <id>

# remember to delete the load balancer manually!
