Infra as code to build/deploy django-wise projects into AWS using:

• VPC
• RDS (Postgres)
• Elasticache (Redis)
• ECS Fargate
• S3 Bucket for statics
• Datadog for Tracing
• CloudWatch for Logging
• CodeBuild/CodePipeline for Deployments

This project is focused in deployment only. all testing/linting and pre deploy tasks should be managed in another engines, I recommend you Github Actions.

1. A S3 bucket for the pipeline artifacts, necesary to keep the AWS pipeline artifacs

2. A SSL certificate for requiered domains, you'll need move NS domain records to Route53

3. Create user with enough permissions to run CDK tasks, and get his aws_client_id and aws_client_secret The user should be able to execute RDS, Elasticache, S3, VPC, ECS tasks

4. Create an s3 bucket for pipeline artifacts and use its name in cdk.stacks.json file in the artifact_bucket key.

5. Create the following configuration files and place them in the root of the project.

   .env

   AWS_DEFAULT_REGION=...
   AWS_REGION=...
   AWS_ACCESS_KEY_ID=...
   AWS_SECRET_ACCESS_KEY=...
   AWS_ACCOUNT_ID=...
   

   cdk.stacks.json

   [
       {
           "stack_name": "<stack-name>",
           "kms_key_uuid": "KMS item UUID",
           "cache_node_type": "AWS Redis node types",
           "num_cache_nodes": 1,
           "database_size": "AWS RDS size",
           "database_name": "anything",
           "database_username": "something",
           "database_allocated_storage": 25,
           "database_encrypted": false,
           "artifact_bucket": "s3 Bucket name for artifacts",
           "certificate_key_id": "Certificate manager Item UUID",
           "repo_owner": "name or organization",
           "repo_name": "repository",
           "repo_branch": "something",
           "dns_name": "main domain",
           "dns_zone_id": "main domain id in route53",
           "dns_stack_subdomain": "stack subdomain just the left side",
           "github_access_token": "Personal access token generate in GitHub",
           "enable_deploy_approval": false
       },
       {...}
   ]
   

This step is different acording your SO. One you have all of this, exec the build command.

make build

1. Check changes

   $ make diff STACK=<stack-name>
   

2. Deploy VPC

   $ make deploy STACK=<stack-name>-vpc
   

3. Deploy Main Stack

   $ make deploy STACK=<stack-name>
   

django-wise template manages environment variables dynamically using chamber for this. To configure chamber you need to do the following:

1. Create a KMS Key (Region could be different) https://console.aws.amazon.com/kms/home?region=us-east-1#/kms/keys/create
2. Setup its alias as parameter_store_key
3. Copy its Key ID and use it in the cdk.stacks.json config file for kms_key_uuid key.

S3 may need a cors configuration:

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<CORSRule>
    <AllowedOrigin>*</AllowedOrigin>
    <AllowedMethod>GET</AllowedMethod>
    <AllowedMethod>HEAD</AllowedMethod>
    <MaxAgeSeconds>3000</MaxAgeSeconds>
    <AllowedHeader>Authorization</AllowedHeader>
</CORSRule>
</CORSConfiguration>
