This repository is used in conjunction with the Contino Infra Engineer to Cloud Engineer Pathway course delivered in Contini-U.
The original repo included and supports the following functionality:
- Dockerfile and docker-compose configuration for 3M based deployments
- Makefile providing basic Terraform deployment functionality using the 3 Musketeers deployment method
- GitHub workflows for supporting basic Terraform deploy and destroy functionality
- Terraform IaC for the test deployment of an s3 bucket
- Node Weather App - https://github.com/phattp/nodejs-weather-app
The solution has been updated with the following functionality:
- Github workflows to build and push the Node Weather App to Amazon ECR
- Deployment of VPC and network constructs, and the required components to run the container on ECS
- Configuration of Go Daddy DNS to configure a CNAME for beardedsamwise.co
- Slack notifications at the end of Github Actions workflows
The application is now fully deployed and available at: www.beardedsamwise.co
Operational metrics are available on Datadog here.
The high level architecture of the solution is as follows. The ALB and ECS instances each have a different security group attached allowing HTTP inbound to the ALB from anywhere, and TCP 3000 from the ALB. The application port is a configurable TF variable.
For more information refer to sg.tf.
The provided makefile, dockerfile , and docker-compose.yml files in the Infrastructure directory work together to create a docker container which is used to run Terraform deployments and other supported commands. It expects AWS account credentials and Go Daddy API credentials (GODADDY_KEY and GODADDY_SECRET) to be passed as environment variables.
To run a simple aws command, ensure you have set your aws temporary credentials in your local environment and run the following.
make list_bucket
Deploying Terraform environment locally - creates tfplan file during plan as input to apply. Apply is auto-approved.
make run_plan
make run_apply
Destroying Terraform environment locally. Destroy plan is speculative. Destroy apply is auto-approved.
make run_destroy_plan
make run_destroy_apply
Terraform init, validate and fmt are run for each of the make commands above.
A similar approach is used as with Terraform.
The provided makefile in the Application directory is used to login in to EKS, as well as build and push Docker images. The makefile expects three environment variables are configured locally.
ACCOUNTID - Your AWS account ID
AWSREGION - The region the Elastic Container Registry (ECR) is deployed to
REPONAME - The name of the Elastic Container Registry (ECR) repo
To log in to EKS execute make login.
To build the supplied Dockerfile execute make build.
To push the built image to ECR execute make push.
To test the image locally before pushing to ECR you can run the Docker image using docker run -p 127.0.0.1:3000:3000/tcp weatherapp:1 where weatherapp:1 is the name:tag of your Docker image.
