We will create a simple Hello World static HTTP Service using Helm, package it and release it to an AWS EKS Cluster.
This tutorial expects you to have
kubectl as well as
helm installed on your computer.
Build our Docker image
Create a file called
Dockerfile and place the below into it:
Now we need to create our
Create a new file called
index.html and add the following code into it:
Now you can run Docker, and push all your files!
Confirm you can reach
http://localhost in your web browser, if you see your
Hello World HTML file, then let’s push this Docker image to Docker Hub.
Note to replace
aogl in the above commands with your own username!
Package and install with Helm
Let’s create a skeleton Helm application, use the CLI to do this:
Now you should have a new directory called
helloworld-chart, which is the same as what you asked Helm to create for you in the previous step.
You can run a
helm lint within this directory, if you want Helm to run some config checks against the files. This is not required though, so only do it when you’ve made changes to the files later on.
Now you want to update the
values.yaml file and replace a couple of things in the
So minus all the comments, your
values.yaml should now look something like this:
Now we are ready to package our Helm application, run the following from the CLI:
You will now have a file called
helloworld-chart-0.1.0.tgz which we will now install to our Kubernetes cluster.
--watch command above will sit and wait to receive an IP address for you.
Now using your web browser, you should be able to navigate to your IP or Load Balancer public IP that
kubectl gave in response to the last step
kubectl get svc.
