To publish a Helm chart on GitHub Pages and enable GitHub Pages on the gh-pages branch, follow these detailed steps:

1. Create the gh-pages Branch of your repository

2. Navigate to the directory containing your Helm chart (Chart.yaml) and run:

helm package job-queue/

This will create a .tgz file (e.g., your-app-0.1.0.tgz).

1. Generate index.yaml: Move the .tgz file to the root of your repository or create a directory structure you prefer. Generate an index.yaml file:

helm repo index .
git add .
git commit -m "Add Helm chart"
git push origin gh-pages

1. Enable GitHub Pages Go to your repository settings:

On GitHub, navigate to your repository page. Click on the Settings tab. Find the GitHub Pages section:

Scroll down to the GitHub Pages section in the settings. Configure the GitHub Pages settings:

In the Source section, select the gh-pages branch from the dropdown menu. Click Save.

Copy the GitHub Pages URL:

After saving, GitHub Pages will provide a URL where your pages are hosted. It will typically be https://your-username.github.io/your-helm-charts.

1. Add the Repository to Helm. Once GitHub Pages is set up, you need to add your repository to Helm on your local machine:

helm repo add job-queue https://puneet105.github.io/job-queue/

1. Update Helm Repositories. Update your local Helm repositories to pull in the latest charts:

helm repo update

1. Install the Helm Chart. You can now install your Helm chart from the repository:

helm install -n job-test job-queue job-queue --create-namespace=true

Testing the Application

Port forwarding

kubectl -n job-test port-forward svc/job-queue 8080:8080

Obtain a JWT Token

You need to log in to obtain a JWT token that will be used for subsequent authenticated requests.

1. Login to Get a JWT Token:Use curl to make a POST request to the /login endpoint:bashCopy codecurl -X POST -d "username=admin&password=password" http://localhost:8080/login
2. If the credentials are correct, you'll receive a JWT token as a response.Example response:jsonCopy code"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6ImFkbWluIiwiZXhwIjoxNjEyNTc1MjAwfQ.xvQyFtLdZDBJF6c4z1P1ZJL9A4VpdvTYPjzMfqV4ouY"
3. Save the JWT Token:Save this token for use in the subsequent steps.

Publish Jobs to the Queues (Redis and RabbitMQ)

Use the JWT token obtained from the login to publish jobs to RabbitMQ, Kafka, and Redis.

1. Publish a Job:Use curl to make a POST request to the /publish endpoint:bashCopy codecurl -X POST -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6ImFkbWluIiwiZXhwIjoxNzIzODk4NjM0fQ.V7C8reg3zfYH14rSF5FnT70jox-Lb-N4XMT2B6LxTsw" http://localhost:8080/publish
2. Replace <your_jwt_token> with the token you obtained earlier.
3. Check the Response:If successful, you should see a response:textCopy codePublished messages to all queues
