Deploying to prod

Things to note:

The containerPort and targetPort need to be the port that is in your CMD within your Docker file so for example:

CMD ["uvicorn", "main:app", "--proxy-headers", "--host", "0.0.0.0", "--port", "80"]

The port here is 80. Therefore you would need to change containerPort and targetPort to 80

Deployment

tam/deployments/<app name>_deployment.yaml

The below config file is what's needed to deploy the application. If the CMD in the Docker file is what you want, you can skip the command and args overrides.

To amend swap out <app name> for the name of your application. Replace the image with the applications image.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: <app name>
  namespace: tam
  annotations:
    fluxcd.io/automated: 'true'
  labels:
    app: <app name>
spec:
  selector:
    matchLabels:
      app: <app name>
  template:
    metadata:
      labels:
        app: <app name>
    spec:
      containers:
      - name: <app name>
        image: registry.pulsepoint.com/tam/exchange-debug-ui:0.0.4

        # the command & args are not needed if CMD in Docker is what you need
        command:
        - "vite"
        args:
        - "preview"
        - "--port"
        - "3000"
        - "--host"
        - "0.0.0.0"
        ports:
        - containerPort: 3000

Services

tam/services/<app name>_svc.yaml

Now to add some services so we can expose our app, below is the template and we would need to adjust app with the correct naming for your app

apiVersion: v1
kind: Service
metadata:
  labels:
    name: <app name>
  name: <app name>
  namespace: tam
spec:
  type: ClusterIP
  selector:
    app: <app name> # this is the label on the pod
  ports:
    - name: http
      port: 80
      protocol: TCP
      targetPort: 3000

Routing traffic

tam/ingresses/<app name>_ingress.yaml

Now to route traffic via ingress controller to pods in the applications service. For this we need to change the hosts this can be anything but should come with a prefix of lga

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    kubernetes.io/ingress.class: nginx
  name: <app name>
  namespace: tam
spec:
  rules:
      http:
        paths:
          - backend:
              serviceName: <app name>
              servicePort: 80
    - host: lga-<appname>.pulsepoint.com # eg: lga-sometool.pulsepoint.com
      http:
        paths:
          - backend:
              serviceName: <app name>
              servicePort: 80
  tls:
    - hosts:
        - lga-<appname>.pulsepoint.com # eg: lga-sometool.pulsepoint.com

If you're adding a host an alias will need to be created for said host.
