Kubernetes

Getting started steps for getting an overview of the Kubernets cluster.

System Requirements

• kubectl

• gcloud

• Lens IDE

Platform specific steps

Linux

Install basic system dependencies:

sudo apt install -y apt-transport-https ca-certificates curl

Add Kubernetes package repository:

sudo curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.30/deb/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-archive-keyring.gpg
echo 'deb [signed-by=/etc/apt/keyrings/kubernetes-archive-keyring.gpg] https://pkgs.k8s.io/core:/stable:/v1.30/deb/ /' | sudo tee /etc/apt/sources.list.d/kubernetes.list
sudo apt update

Install kubectl:

sudo apt-get install -y kubectl

Add Google package repository:

curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo gpg --dearmor -o /usr/share/keyrings/cloud.google.gpg
echo "deb [signed-by=/usr/share/keyrings/cloud.google.gpg] https://packages.cloud.google.com/apt cloud-sdk main" | sudo tee -a /etc/apt/sources.list.d/google-cloud-sdk.list
sudo apt update

Install gcloud:

sudo apt install -y google-cloud-cli google-cloud-sdk-gke-gcloud-auth-plugin

MacOS

Install kubectl:

brew install kubectl

Install gcloud:

brew install google-cloud-sdk
gcloud components install gke-gcloud-auth-plugin

Lens IDE

Install the relevant package for your operating system.

Configuration

Login to your account:

gcloud auth login

Connect to development cluster:

gcloud container clusters get-credentials p4-development --zone us-central1-a --project planet-4-151612

Connect to production cluster:

gcloud container clusters get-credentials planet4-production --zone us-central1-a --project planet4-production

Verify available clusters:

kubectl config get-contexts

Rename contents to a human readable alias. Example:

kubectl config rename-context [long-cluster-name] p4-development

Switch to that cluster if you have more than one:

kubectl config use-context p4-development

Verify the connection:

kubectl get nodes
kubectl get namespaces
kubectl get pods -n [namespace]
