How to deploy application to Google Cloud.

First add the app engine plugin into maven.
Open console - Select Create a project - Give a project name. Note the project Id.
Enable billing for the project.
In App Engine - Select the language - Then set the region.
Install the Google Cloud SDK. Open sdk in terminal - Set the project gcloud config set project projectId
See the project is in same cloud configure - gcloud config list

In gcloud we need to set the environment we are using and the jdk version.
There should be one yml file in the appEngine folder. Inside the app.yml file.

runtime: java
env: flex
runtime_congif:
    jdk: openjdk8
handlers:
    url: /.*
    script: this field is required, but ignored

Maven mvn clean package appengine:deploy in the application.

Spring Boot Application in MYSQL and GCLOUD - Cloud SQL.

In console - Hamburger - SQL - In Cloud SQL we need to make the instance. Create the instance and version.

There will be a option called open cloud shell. In the cloud shell we need to create the db connect - gcloud sql connect INSTANCE_NAME --user=PWD --quiet

Now there will be a SQL query like Create Database Products and Use Products
In the sidebar under the SQL there is Database there we can see the database product.

In the application.yml file we need to set the url. In the url there is connection name and it is cloud sql instance and there is socketFactory.

In Pom we need the mysql connector dependent and the mysql socket factory dependency.

Now we build the project and the jar file is created and in the project directory we get the jar file and connect to the SDK login with user and select the project where to deploy the application. In the same directory open cmd and gcloud app deploy JAR_FILE_NAME.jar. When deployment is done there is a url like sonic-passkey copy the url and the link in the url and there will be response.

Spring Boot Application and GCLOUD and Cloud Spanner.

Create the instance and db in Spanner.

Configure the service account in GCloud.
In IAM and Admin - Create a new Service Account to access the spanner.

Then there is an option to create a key and get the key and put in the resource folder of the application.
