fibonacci web server app

Messing around with Docker some more.

This project works with docker to test, build and start an unnecessarily complex app to work with multiple containers and integrating them.

Based on the Udemy course: Docker and Kubernetes: The Complete Guide by Stephen Grider starting at Section 8: "Building a Multi-Container Application"

quick start

Note: The terraform configs are specific to my environment. You'll have to change the "hard-coded" values (that's right - I didn't parameterize! :-p)

  1. clone the repo
  2. run terraform init & terraform apply in terraform directory
  3. run eb init & eb deploy in fibo-web directory

detailed setup/configuration/use

Note: These steps are not exact. Derived from a previous app (React App) from the same Udemy course.

local dev

  1. brew install node
  2. mkdir fibo-web fibo-web/{client,server,worker,nginx}
  3. extract files Section: 9 Lecture: 116
  4. create {client,server,worker,nginx}/Dockerfil.dev files
  5. create nginx/default.conf file
  6. create docker-compose.yml file
  7. docker-compose up [--build]

add CI/CD (Jenkins)

  1. AWS credentials in ~/.aws/config
  2. Docker Hub credentials as Jenkins environment vars in global config
  3. Create/Modify Jenkinsfile
  4. Jenkins
  • multibranch project
  • specify the correct Jenkinsfile
  • set up the GitHub creds (username/password) standard or Pers Access Token

AWS infra config

automated via Terraform

  1. Change working directory to terraform
  • cd terraform
  1. Apply the terraform configurations (may need to run terraform init first)
  • terraform apply

manually via AWS Console

  1. AWS Elastic Beanstalk (Application and Environment)
  • Create the app and env (web server / multi-container docker)
  • Set up environment variables (Dockerrun.aws.json with resources below)
  1. Amazon RDS (PostgreSQL)
  • Create an RDS DB (Dev/Test) (credentials/db name to match Dockerrun.aws.json)
    • small burstable instance, minimal memory and disk space
    • no extra anything, automatic backups, multi-az, enhanced monitoring
  • Create a AWS SG for PostgreSQL
  1. Amazon ElastiCache (Redis)
  • Create a Redis Cluster
    • zero replicas, no automatic backups
  • Create a AWS SG for Redis

AWS Elastic Beanstalk CLI (eb)

  1. install AWS ElasticBeanstalk CLI (eb)
  2. initialize the EB environment: eb init [--profile PROFILE]
  3. deploy to EB: eb deploy [--staged] (in the Jenkinsfile)
