Deploynment

• How to use Docker to deploy and run application.
• How to use .env files.
• How to create base CI\CD configuration for TravisCI.
• How to run tests with TravisCI.
• How to deploy application on AWS cloud services using TravisCI.
• How to use RDS, ECR, ECS, EC2, Elasitcashe from AWS.

Technologies:

• TypeScript
• Nest.js

Installation

$ npm install

Running the app

# development
$ npm run start

# watch mode
$ npm run start:dev

# production mode
$ npm run start:prod

Test

# unit tests
$ npm run test

# e2e tests
$ npm run test:e2e

# test coverage
$ npm run test:cov

SSL

To run application with TLS certificate perform next steps:

1. Generate TLS certificate using next command:

openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout key.pem -out cert.pem

2. Move generated certificates to ssl folder.
3. Run application.

Docker

docker build . -t ts-nest
docker run -i -t -p 3000:3000 ts-nest

Or if you can run bash then just,

sh run.sh

TraviCI

1. Create TravisCI account and connect it to your GitHub account.
2. In repositories list choose this repository and create build configuration.
3. Travis will run tests and deploy on every push to the repository master branch.

AWS

1. Create AWS Account
2. Add PostgreSQL DB in RDS
3. Add Redis in ElastiCache
4. Add repository in ECR
5. Add Task definition and Cluster in ECS
6. Add these invironment varialbles to Travis CI variables:

   AWS_ACCESS_KEY_ID
   AWS_DEFAULT_REGION
   AWS_SECRET_ACCESS_KEY
   CLUSTER_NAME             ## ECS
   IMAGE_REPO_URL           ## ECR
   SERVICE_NAME             ## ECS
   

7. Push to GitHub and run Travis CI pipeline
