Google Kubernetes Engine

$ gcloud config set compute/zone us-central1-f

$ gcloud container clusters create io

$ gcloud container clusters create hello-world \ --num-nodes 3 \ --machine-type f1-micro \ --zone us-central1-f

Get the sample code

$ git clone https://github.com/googlecodelabs/orchestrate-with-kubernetes.git

$ cd orchestrate-with-kubernetes/kubernetes

$ ls -al

Quick Kubernetes Demo

$ kubectl run nginx --image=nginx:1.10.0

$ kubectl get pods

$ kubectl expose deployment nginx --port 80 --type LoadBalancer

$ kubectl get services

$ curl http://<External IP>:80

Creating Pods

$ cat pods/monolith.yaml

$ kubectl create -f pods/monolith.yaml

$ kubectl get pods

$ kubectl describe pods monolith

Interacting with Pods

$ kubectl port-forward monolith 10080:80

$ curl http://127.0.0.1:10080

$ curl http://127.0.0.1:10080/secure

$ curl -u user http://127.0.0.1:10080/login

$ TOKEN=$(curl http://127.0.0.1:10080/login -u user|jq -r '.token')

$ curl -H "Authorization: Bearer $TOKEN" http://127.0.0.1:10080/secure

$ kubectl logs monolith

$ kubectl logs -f monolith

$ curl http://127.0.0.1:10080

$ kubectl exec monolith --stdin --tty -c monolith /bin/sh

# ping -c 3 google.com

# exit

Services

Creating a Service

$ cd ~/orchestrate-with-kubernetes/kubernetes

$ cat pods/secure-monolith.yaml

$ kubectl create secret generic tls-certs --from-file tls/

$ kubectl create configmap nginx-proxy-conf --from-file nginx/proxy.conf

$ kubectl create -f pods/secure-monolith.yaml

$ cat services/monolith.yaml

$ kubectl create -f services/monolith.yaml

$ gcloud compute firewall-rules create allow-monolith-nodeport --allow=tcp:31000

$ gcloud compute instances list

$ curl -k https://<EXTERNAL_IP>:31000

$ kubectl get services monolith

$ kubectl describe services monolith

Adding Labels to Pods

$ kubectl get pods -l "app=monolith"

$ kubectl get pods -l "app=monolith,secure=enabled"

$ kubectl label pods secure-monolith 'secure=enabled'

$ kubectl get pods secure-monolith --show-labels

$ kubectl describe services monolith | grep Endpoints

$ gcloud compute instances list

$ curl -k https://<EXTERNAL_IP>:31000

Deploying Applications with Kubernetes

Creating Deployments

$ cat deployments/auth.yaml

$ kubectl create -f deployments/auth.yaml

$ kubectl create -f services/auth.yaml

$ kubectl create -f deployments/hello.yaml

$ kubectl create -f services/hello.yaml

$ kubectl create configmap nginx-frontend-conf --from-file=nginx/frontend.conf

$ kubectl create -f deployments/frontend.yaml

$ kubectl create -f services/frontend.yaml

$ kubectl get services frontend

$ curl -k https://<EXTERNAL-IP>

Clean up

$ cat cleanup.sh

$ chmod +x cleanup.sh

$ ./cleanup.sh

$ gcloud container clusters delete io --zone
