This project deployed an API service to AWS environment as ECS

## File List 
Golang API service
 - server.go (source file)
 - server_test.go (unit test file)
 - go.mod, go.sum (go module files which list all the dependencies)

 Terraform
 - main.tf (AWS infrastructure)

 Container
 - Dockerfile (Used to build the container)

 Jenkins
 - task_definition.json (defines the ECS task)
 - jenkins_build.sh (Shell command used in Jenkins freestyle pipeline)
 - jenkins.output (Sample jenkins build job output)

 Final test
 - curl_api_test.sh (A few curl command to test api service)

 ## Process
 1. Deploy AWS infra
    $ cd ./terraform/
    $ terraform init
    $ terraform plan
    $ terraform apply

2. Build Jenkins freestyle pipeline
    * Use github as source version control backend
    * Configure build trigger webhook
    * Add jenkins_build.sh content to new build job execute Shell

3. Update code to github repository
    * Everytime git push to master branch
    * Jenkins job is automatically triggered to build the docker image and update to AWS ECS
