k3s on AWS ec2

Deploy an AWS ec2 instance with a k3s cluster installed.

Prerequisites

aws cli and terraform

Login to AWS

Create a SFU profile for your own sandboxed AWS environment and add it to ~/.aws/config eg:

[profile my-sfu-sandbox]
sso_start_url = https://sixfeetup.awsapps.com/start
sso_region = us-east-1
sso_account_id = 000000000000
sso_role_name = admin
region = us-east-1
output = json

Switch to your profile and log in:

export AWS_PROFILE=my-sfu-sandbox
aws sso login

Deploy k3s instance on AWS

make deploy

Add k3s cluster config

Once your ec2 instance is up and running, you can run make config to add the cluster to your local Kubernetes configuration. This will install k3s on the ec2instance and add the kubeconfig to ~/.kube/config.

Check that the new cluster is listed:

kubectl config get-contexts

Credentials

In order for Skaffold or Tilt to push images and Kubernetes to pull images, we need to authenticate against an image repository.

export ECR_REPO=xxxxxxxxx.dkr.ecr.us-east-1.amazonaws.com
aws sso login
make kubecreds
