run in AWS

Deploy app's infrastructure in AWS ECS

Push docker image to a registry

You can use Docker Hub public repo for it:

docker tag node_app:<version> <user-name>/pageview_counter:<version>
docker push <user-name>/pageview_counter:<version>

And change image name in terraform, in file ./tf/modules/ecs/variables.tf, variable "image".

Also you can tag and push image when staring app local using scrip /run_local.sh. You'll need to uncomment this part.

For example if you want to deploy in prod environment run following commands:

cd ./tf/prod
terraform init
terraform plan
terraform apply

It will deploy 4 containers with version 1.0 (these values are set in terraform's config for dev envioronment).

Deployment script for dev environment: ./deploy_dev.sh
