Workflow for Tesla

workflow.md

To deploy a change to an app to stage, in the current workflow, you'd do the following:

1. Accept our previous github invitation for user l85m at https://github.com/gruntwork-io
2. git clone https://github.com/gruntwork-io/sample-app-tesla && cd sample-app-tesla
3. docker-compose up
4. Open http://localhost:3000 to see the app.
5. Make whatever changes you want and refresh your browser. A good file to change is app/index.html.
6. git commit -am "some commit message"
7. git push
8. Normally, this would kick off a build in Jenkins which would automatically push a new Docker image to ECR and then auto-deploy to stage or prod. But because we haven't configured Jenkins yet, you would manually deploy as follows:
   1. Login your local environment to ECR: aws ecr get-login --region us-east-1
   2. cd sample-app-tesla
   3. Build the new Docker image: docker build -t sample-app-tesla .
   4. Tag it: docker tag sample-app-tesla:latest 427672229586.dkr.ecr.us-east-1.amazonaws.com/sample-app-tesla:latest
   5. Push it to Amazon ECR: docker push 427672229586.dkr.ecr.us-east-1.amazonaws.com/sample-app-tesla:latest
   6. Change this value in terraform.tfvars to the new docker image tag value (e.g. latest).
   7. From this directory, run terraform apply.
   8. Amazon ECS will auto-deploy to http://stage.gruntwork-tesla.com/
