Simple API Deployment to GKE

This project demonstrates how to deploy a simple python project (in this case a FAST API project) to GKE using Cloud Build and using Ansible to Provision a GKE cluster.

Cloud build is configured with a trigger to auto deploy the project when a commit is pushed to the main branch.

Provisoon GKE CLuster

Provision a cluster, specified as prod-cluster

Reguirements

• Ansible
• GCP Ansible Collection

Prerequisites

1. Obtain a GCP default Compute Engine service account file(usually .json) and place it at the root folder of the project
2. Obtain the Google Project ID

Steps

1. Ensure all the requirents are isntalled in the virtual environment

   $ pip install -r requirements.txt"
   

2. Run the playbook with the following option to provide for the google project id

   $ ansible-playbook -e project_name=<GCP_PROJECT_ID> ansible/playbook.yml
   

Run FASTAPI

Local Setup Steps

1. Ensure all requirements are in the local environemt

   $ pip install -r requirements.txt"
   

2. Run the API in dev mode

   $ uvicorn main:app --reload
   

3. Navigate to http://127.0.0.1:8000/docs to read the API docs
4. A simple TODO list can be found in http://127.0.0.1:8000/todo/fe

To Trigger a deploy by cloudbuild run

```
$ gcloud builds submit --substitutions=SHORT_SHA=<GIT_COMMIT_SHORT_SHA>,_CLOUDSDK_CONTAINER_CLUSTER=<GCP_CLUSTER_NAME>,_CLOUDSDK_COMPUTE_ZONE="CLUSTER_LOCATION"
```
