Setup - AWS

Setting up a Kubernetes Cluster with AWS

Deploy a Kubernetes cluster in AWS using EKS service.

Requirements

  1. 1.
    AWS account
  2. 2.
    CLI and AWS credentials configured
  3. 3.
    AWS IAM Authenticator
  4. 4.
    kubectl
  5. 5.
    wget (required for EKS module)
LINUX/MAC is the preferred method of setup.
Windows should choose either:
  1. 1.
    Deploy a THORNode from a Linux VPS.
  2. 2.
    Use Windows Subsystem for Linux - https://docs.microsoft.com/en-us/windows/wsl/about****

Steps

Firstly, clone and enter the cluster-launcher repository. All commands in this section are to be run inside this repo.
git clone https://gitlab.com/thorchain/devops/cluster-launcher
cd cluster-launcher
Then install the terraform CLI:
LINUX/MAC
Install Terraform:
brew install terraform

AWS CLI

In order for Terraform to run operations on your behalf, you must install and configure the AWS CLI tool. ****To install the AWS CLI, follow these instructions, or choose a package manager based on your operating system.
LINUX/MAC
Use the package manager homebrew to install the AWS CLI.
brew install awscli
aws configure
You will be asked for you AWS access credentials (retrieve from AWS IAM from the AWS web console.)
IAM -> User -> Security Credentials -> Create Access Key.
Make sure you handle your secrets securely!

AWS IAM Authenticator

You also must install and configure the AWS IAM Authenticator tool. ****To install, follow these instructions, or choose a package manager based on your operating system.
LINUX/MAC
Use the package manager homebrew to install the AWS IAM Authenticator.
brew install aws-iam-authenticator

Kubernetes Control Tool

You must install and configure the Kubernetes CLI tool (kubectl). ****To install kubectl , follow these instructions, or choose a package manager based on your operating system.
LINUX/MAC
Use the package manager homebrew to install kubectl.
brew install kubernetes-cli

wget && jq

You also need wget and jq, follow these instructions, or choose a package manager based on your operating system.
LINUX/MAC
Use the package manager homebrew to install wget and jq Note: You most likely have these installed already.
brew install wget
brew install jq

Deploy Kubernetes Cluster

Use the commands below to deploy an AWS EKS cluster. You can run the make command that automates those command for you like this:
make aws
During the deploy, you will be asked to enter information about your cluster:
Regions
Note: AWS EKS is not available in some regions
Or manually:
cd aws/
terraform init
terraform plan # to see the plan
terraform apply
Final success message: Apply complete! Resources: 30 added, 0 changed, 0 destroyed.
If you are a returning node operator and you wish to use the same node name, the Cloudwatch log files from your previous session will block this step. You need to manually delete the logs from your console:
Cloudwatch / Cloudwatch Logs / Log Groups -> "delete"
Deploying a cluster takes ~10 minutes

CONFIGURE kubectl

This is done automatically during provisioning. To configure authentication from the command line, use the following command. It will get the access credentials for your cluster and automatically configure kubectl in case you need to to manually reconfigure kubectl.
make kubeconfig-aws
Or get your kubeconfig file manually:
(cd aws && aws eks --region $(terraform output -raw region) update-kubeconfig --name $(terraform output -raw cluster_name))
To verify, run this, and check the status is "Ready":
kubectl version
kubectl cluster-info
kubectl get nodes
You are now ready to deploy a THORNode.

BACKUPS (OPTIONAL)

Once your node is running, use the following command to automatically backup the Persistent Volumes for your Kubernetes cluster. This may help in recovering your node in the event of a disaster.
Enable backups:
make aws-backups
Disable backups:
make aws-destroy-backups
