Creating Kubernetes Cluster on Google Cloud

Login and Select Kubernetes Engine on Google Cloud Platform

Create a cluster by running the following command on cloud shell

Retrieve credentials for kubectl

Grant cluster administrator (admin) permissions to the current user

To create the necessary RBAC rules for Istio, the current user requires admin permissions.

Configuring Istio

Downloading Istio

Go to the Istio release page to download the installation file for your OS, or download and extract the latest release automatically (Linux or macOS) as mentioned in https://istio.io/docs/setup/getting-started/

Run the following in the cloud shell

Adding istioctl client to your cloud system path

Configuring Istio Profile

For this installation, we use the demo configuration profile. It’s selected to have a good set of defaults for testing along with dashboards like kiali, prometheus etc.

Configuring Istio Namespace to allow injection

Add a namespace label to instruct Istio to automatically inject Envoy sidecar proxies when you deploy your application later

Configuration changes to Fiorano installer for cloud setup

In the Fiorano Latest installer, change the IP for Cassandra, Primary and Secondary URL as 10.35.240.20 (configured cluster IP for AMS) in config deployer in for server1 profile AGS.

Configuring the Docker image

1. Upload the tar files created for AMS and AGS compressed as zip to the google cloud console, after upload extract the same. 
2. Change directory and go to the directory containing the docker images using cloud shell 

3. Run the following code blocks to load docker images to the cloud docker
   

   Icon

   Change the FIORANO_DOCKER_IMAGE to the actual docker image file name for both AMS and AGS

4. Add Cred Helper
   Add the Docker credHelper entry to Docker's configuration file, or creates the file if it doesn't exist. This will register gcloud as the credential helper for all Google-supported Docker registries. ( refer to https://cloud.google.com/container-registry/docs/pushing-and-pulling)
   

   

5. Create tags with registry name

   Example

6. Push the tagged images to container registry
