AWS Elastic Kubernetes Service Kubernetes 1.28 Update #237

4141done · 2023-11-14T20:31:21Z

Updates for EKS 1.28

This change brings MARA up to date for execution in Amazon EKS running Kubernetes 1.28.
The additional changes in this PR are:

Changes to python versions (3.11.6 is suggested, 3.11 required) to support building our combination of dependencies
It is now required to install the aws tool yourself

The docker-based runs have not been updated and will be addressed in a future PR.

Run Instructions

Prerequisites

An AWS account (be aware that this stand up is big and requires t2.large instances with the accompanying costs)
A (free) Pulumi account
Python 3.11 (3.11.6 is tested) installed. Consider using a tool like pyenv or asdf
The aws cli tool installed and configured
(optional) The kubectl tool installed
(optional) The k9s tool installed

All of the other suggested tooling can be managed with asdf if you want.

NOTE FOR containerd USERS ON ARM64 ARCHITECTURE: this will not work using containerd for the moment due to how it handles manifests. If you are using Docker for Mac on an M1/M2 system you'll need to disable the containerd mode before continuing

Steps

git clone --recurse-submodules https://github.com/nginxinc/kic-reference-architectures to check out this repo and the demo app.
git checkout pulumi_2023 to get this branch
./bin/setup_venv.sh to set up python and install all the dependencies
In ./config/pulumi create a file like this with the name Pulumi.your_stack_name.yaml

Execute the standup script. The environment variable isn't strictly necessary if you are not on an linux/arm64 machine but it doesn't hurt to leave it there.

DOCKER_DEFAULT_PLATFORM=linux/amd64 pulumi/python/runner -d -p aws -s your_stack_name up

Exploring

Once the standup script is complete, you should see something that looks like this:

application_url     : "https://longstring-119454905.us-west-2.elb.amazonaws.com"

You can use that to visit the Bank of Sirius UI

To view other installed tooling, first make sure you have kubectl configured to have access to your cluster like this:

aws eks update-kubeconfig --region YOUR_REGION --name CLUSTER_NAME --profile PROFILE_NAME

The CLUSTER_NAME can be obtained either from the AWS UI or by looking at the output from this project in the "EKS" section at the beginning. It will look like this:

Outputs:
    cluster_name: "aws-eks-yourstackname-eksCluster-cf1f5e2"

Once that is done, run:

./bin/test-forward.sh

Which till create tunnels to the appropriate endpoints in the deployed MARA instance.

It is also recommended to install and deploy k9s (link) to explore the Kubernetes cluster. If you set up your kubeconfig in the earlier step then it should just work.
