Kubernetes

Prerequisites

This document assumes that you have docker, minikube and kubectl installed.

Note: You can use something other than minikube to run the cluster.

Deployment

Deploy all services

To deploy the whole app to the cluster, run the following commands. If you want to deploy the app to a specific namespace, you can provide it as an argument.

kubectl apply -R -f deploy/k8s -n <namespace>

To see the status of the deployment, run the following command:

kubectl get deployments -n <namespace>

Deploy specific services

You can deploy specific services by running the following commands:

kubectl apply -f deploy/k8s/global-configmap.yml -n <namespace>

Remove services

After deploying the app to the cluster, you can remove the services by running the following commands:

# Remove single service
kubectl delete -f deploy/k8s/global-configmap.yml -n <namespace>

# Remove all services
kubectl delete -R -f deploy/k8s -n <namespace>

Ingress configuration

To be able to access the API from outside the cluster, you need to configure the ingress by modifying the /etc/hosts file.

First, you need to get the IP address of the ingress controller.

kubectl get ingress -n <namespace>

Note: It can take a while for the ingress to be ready.

Then, you need to add the IP address of the ingress controller to the /etc/hosts file. The format for the file is:

# <ip>          <domain> [<domain> ...]
192.168.46.36   api.local
