Deployement Service to Google Kubernetes Engine Cloud (GKE)

This time we will try to deploy our service to the Google Cloud Platform Server. Google Cloud has been specifically provided for deployment in the form of Kubernetes, namely in the form of Google Kubernetes Engine so that when we want to deploy our services it becomes easier.

You also need to know that if we haven’t subscribed to Google Cloud, we first need to subscribe or register for free for the first year to be able to use Google Cloud with our respective Gmail accounts.

So, let’s try accessing the Google Cloud website on this site Google Cloud and choose the console or register if you have not access to the Google Cloud.

Create a Kubernetes Cluster

Preparations if we want to deploy our services on GKE, we need to carry out the following stages.

Create a Kubernetes Cluster on Google Cloud, if you want to understand more, read several steps there and we can also do customization starting from virtual cloud specifications such as memory requirements, CPU and others.
Select the create button after all the configurations have been set, or if you want the default then just press the create button until you wait for the cluster to be successfully created as below.
When finished, we continue by selecting Connect to the cluster that we have created.
A pop up will appear and then copy the terminal and select Run in Cloud Shell

A terminal will appear at the bottom of the display, then enter and wait until everything is finished.

If it appears on the terminal as below, it means the process is complete

bash

1ihsan_android@cloudshell:~ (genial-upgrade-162704)$ gcloud container clusters get-credentials voting-app --region asia-southeast1 --project genial-upgrade-162704
2Fetching cluster endpoint and auth data.
3kubeconfig entry generated for voting-app.

Clone YAML Files

Prepare the YAML file template that we have previously created or can clone on [this] github (https://github.com/santekno/kubernetes-for-beginners )

bash

1git clone https://github.com/santekno/kubernetes-for-beginners
2cd kubernetes-for-beginners/
3ls -l
4total 20
5drwxr-xr-x 7 ihsan_android ihsan_android 4096 Mar 25 07:03 demo
6drwxr-xr-x 2 ihsan_android ihsan_android 4096 Mar 25 07:03 deployments
7drwxr-xr-x 2 ihsan_android ihsan_android 4096 Mar 25 07:03 pod
8drwxr-xr-x 2 ihsan_android ihsan_android 4096 Mar 25 07:03 replicasets
9drwxr-xr-x 2 ihsan_android ihsan_android 4096 Mar 25 07:03 services

Let’s see all file that already to clone on this repository, then create the command bellow to deploy all services

bash

1kubectl create -f demo/voting-app/voting-app-deployment.yaml
2kubectl create -f demo/voting-app/voting-app-service.yaml
3kubectl create -f demo/result-app/result-app-deployment.yaml
4kubectl create -f demo/result-app/result-app-service.yaml
5kubectl create -f demo/redis/redis-deployment.yaml
6kubectl create -f demo/redis/redis-service.yaml
7kubectl create -f demo/postgres/postgres-deployment.yaml
8kubectl create -f demo/postgres/postgres-service.yaml
9kubectl create -f demo/worker-app/worker-app-deployment.yaml

waiting for a minutes or we can see to make sure the status the services will be running or not with the command below.

bash

1kubectl get svc,deployment,pods

The result will be show below.
