Initial Steps (readying your app)

Note: I assume you already have a minikube running

1. check if you have any pods running with kubectl get pod and stop them if so

2. create external configurations

   • kubectl apply -f mongo-config.yaml
   • kubectl apply -f mongo-secret.yaml ★ the -f is for file

3. create connection for the database

   • kubectl apply -f mongo.yaml

4. deploy the web app

   • kubectl apply -f webapp.yaml

Kubectl

1. check your pods using kubectl get all
2. check your configmap using kubectl get configmap
3. check your secrets using kubectl get secret

• you can use kubectl get [component_name] to get some data for any component or run kubectl get --help for help with the get subcommand

• you can use kubectl describe service [service_name] to get a description of the service

• you can use kubectl logs [pod_name] to get the logs for that pod

Accessing the Application Externally

In our case from the browser

1. use kubectl get svc to get the service
2. get the nodPort's ip using minikube ip ★ you can access more data using kubectl get node -o wide
3. access the ip using the corresponding IP address : port
