Star Wars knowledge base

Based on https://swapi.dev

This is my diploma app, that could be used as a sample.

This repository contains:

1. SWKB App code
2. IaaC scripts to build infrastructure on Yandex Cloud
3. Kubespray to set up Kubernetes on Yandex Cloud

Steps to build and deploy SWKB App

Step 1. Prepare credentials

To set up infrastructure on Yandex Cloud you need:

• Create account on Yandex cloud
• Get OAuth token, cloud id, folder id, zone (AZ). To get OAuth visit Yandex docs https://cloud.yandex.ru/docs/iam/concepts/authorization/oauth-token
• Create environment variables:
  • YC_TOKEN=your_oauth_token
  • YC_CLOUD_ID=your_cloud_id
  • YC_FOLDER_ID=your_folder_id
  • YC_ZONE=ru-central1-a (all Yandex Cloud AZs here)
• Create ssh-key (by default username is ubuntu) and save it to ~\.ssh\id_rsa. You can change user/key parameters on variable.tf file
  • ssh-keygen -t rsa -b 2048 -C [email protected]
• Create two git-hub secrets (repository secrets) username: DOCKERHUB_USERNAME, DOCKERHUB_TOKEN

Step 2. Create cloud infrastructure by terraform

Run terraform apply from StarWarsKb.Infrastructure/Terraform directory. If you want to set your db password then run terraform apply -var="db_password=your_pass"

By default terraform creates bastion host, 1 master node and 2 worker nodes. You can change these parameters, more info about count and size of nodes is here: StarWarsKb.Infrastructure/Terraform/README.md

Output would contain IP of bastion-host.

Step 3. Create Kubernetes cluster and deploy services

Connect to bastion host by ssh:

ssh ubuntu@bastion_public_ip

After that run installation script (I don't know what was wrong with userdata):

sudo cp /var/lib/cloud/instance/user-data.txt ~/magic.sh && sudo chmod 755 magic.sh && sudo ./magic.sh

kubectlwould be installed on master-host.
