Google K8S managed entirely with Terraform.

Google Cloud K8S cluster using terraform.

This project aims at creating a Highly scalable K8S cluster by using terraform.
The idea is to follow Infrastructure as code such that it is easy to manage. In order to maintain cross compatablity between cloud providers terraform is used instead of google deployment manager/AWS cloud formation.

Requirements:

1. Google Cloud Account.
2. Terraform.
3. Google SDK.

GCP Resources used:

1. VPC.
2. Kubernetes cluster with custom node pool.
3. Memorystore.

Prerequisites:

1. Google service account with permissions to create K8S cluster.
2. Service account file.

Steps to run:

1. Run terraform init to download required libraries.
2. Run terraform plan which will show what will happen.
3. Run terraform apply and approve te changes by typing yes when prompted.

Notes:

1. All the variables have default value in order to over ride either use -var=variablename=value or export them as TF_VAR_variablename. As mentioned in the documentation.
2. Since mostly we will be given service account file with least privileges. Service account creation is not a part of the project. The same can be created with gcloud as per this google community tutorial.
