You can validate this against localhost:8080

Hello Docker World

Pushing the docker image

Now we need a repository to push this into. We can use Pivotal/AWS/Google containers.

Let's use google container.

Google Cloud

Create a project in Google cloud through console or command line. I just chose google Console

Install Google SDK (onetime)

This is to get command line access to gcloud

Enable APIs

Enable 2 APIs

Container Registry API
Kubernetes Engine API

##Push the docker Image to Google Cloud Container Registry First Create a tag

docker tag <user-name>/<sample-image-name> gcr.io/<project-id>/<sample-image-name>:<tag>

docker tag vis.com/springboot-docker gcr.io/springboot-docker/springboot

(One time)Enable Gcloud Docker

https://cloud.google.com/container-registry/docs/advanced-authentication

gcloud components install docker-credential-gcr

docker-credential-gcr configure-docker

Push the image

docker — push gcr.io/your-project-id/<project-id>/<sample-image-name>:<tag>

docker  push gcr.io/springboot-docker/springboot

Create Cluster

https://cloud.google.com/kubernetes-engine/docs/quickstart onetime. gcloud components install kubectl

1.Set project ID gcloud config set project PROJECT_ID The project ID is available in the console 2.Set Compute Zone gcloud config set compute/zone COMPUTE_ZONE
ex; us-west1-a 3.Create Clusters

cloud container clusters create springboot-cluster --num-nodes=3

4. Expose Port

kubectl run spring-server --image gcr.io/springboot-docker/springboot --port 8080
kubectl expose deployment spring-server --type LoadBalancer --port 80 --target-port 8080

5. Get IP Address

kubectl get service spring-server
