Description

For automation deploy you need:

• manual create all steps in "part #1"
• setup variables in /terraform/variables.tf

Part #1: Manual Setup

Step 1.1: Create AWS Account

• Sign up for an AWS account if you don't have one.

Step 1.2: Create S3 Bucket for Terraform State

• Create an S3 bucket to store your Terraform state.
• Consider using DynamoDB for state locking to prevent concurrent Terraform executions (this will be addressed later).

Step 1.3: Setup Secrets in GitHub

• Add AWS credentials to GitHub Secrets for secure access.

Step 1.4: Configure AWS Credentials

• Use the AWS Console to set up credentials for:
  • Docker Hub
  • Database and wp-admin (remember to configure usernames for the database and WordPress later).

Step 1.5: Create SSH Key for EC2 Instance

• Generate an SSH key for your EC2 instance.

• (Note: It’s recommended to use Terraform for this, but you can skip regeneration if you already have a key.)

• By the whay: you will need this key for create DB on RDS-MySQL server...

Part #2: Terraform

1. Run the following commands:

   cd terraform
   terraform init
   terraform apply
   

after this moment you will created:

• vpc..
• subnets..
• rds mysql
• elastice cache REDIS
• bastion host for create database and users for wordpress.. )
• other .... P.S. don't forgot to setup variables ))

Part #3: CI/CD

Step 3.1: Create Docker Container

• Objective: Build a Docker container with the WordPress source code.
• Action:
  • Push the Docker container to Docker Hub.
• Benefits of using container:
  • Isolation of the site.
  • Facilitates future migrations.

Step 3.2: Create AMI Image

• Source: Utilize blank-wordpress-code from a GitHub repository (unzip the archive from WordPress.org).
• Note: WordPress requires database connections (MySQL and Redis) to function properly when deployed within AWS.

Use the Installation Script

• Script Path: /packer/scripts/install_wordpress.md
• Installation Tasks:
  • Set up the database.
  • Set up Redis.
  • Set up HTTPS plugin (currently not functional; ongoing work).
  • Set up S3 (to be addressed within 1-2 days).

Note: We can use the source code with installed plugins, but the functionality without prior setup is uncertain.

Step 3.3: Deployment

• Objective: Implement green/blue deployment strategy.
• Action: Switch running instances in the Auto Scaling Group (ASG) to ensure zero downtime during updates.
