Microservices with Node JS and React Exercise

Development

• Run Kubernetes cluster inside Google Cloud or on Docker Desktop
• Use Ingress Inginx Controller to access the cluster
• Streamline development code updates using Skaffold

Switch between local K8s and GKE

For running the cluster n Docker Desktop:

1. Images in services must point to docker hub
2. Skaffold images must be set to docker hub
3. Set build.local to push: false in skaffold.yaml
4. Ingress service host must be set a domain pointing to 127.0.0.1 by tweaked hosts config

For running on GKE

1. Images must be set to us.gcr.io/ticketings/
2. Skaffold setting googleCloudBuild should be set to projectId: ticketings
3. Ingress service host should be set to ticketings.gc

Setup k8s cluster

1. Setup Ingress controller
2. Add JWT secret in the cluster kubectl create secret generic jwt-secret --from-literal JWT_KEY=asdf

Connect kubectl to GKE from local machine

1. Go to Kubernetes Engine page and select the cluster.
2. Press on >_Connect to open a cloud console.
3. Copy gcloud authorization command to local terminal. It will swtich local kubectl context to gcloud, e.g. gcloud container clusters get-credentials ticketing-dev --zone europe-west3-a --project ticketings.
4. Troubleshoot: Make sure gcloud is logged in.

Setup a new service

1. Create a source folder
2. Build an image
3. Create a k8s deployment and service
4. Setup routing in the ingress service
5. Update skaffold config
