This repository is intended as a companion piece for the following blog: https://doordash.engineering/2023/03/07/how-to-speed-up-local-development-of-a-docker-application-running-on-aws/
To run the example backend microservice in this repository you will need the following:
- Node version >= 16.13 but <17 installed.
- Docker Desktop installed and running.
- postgresql installed.
brew install postgresql
- awslocal installed.
First run the following commands:
npm install
Then to start the local development environment run:
docker-compose up
To spin down the local development environment you can just quit the docker-compose process by using ctrl-c.
While the docker-compose environment is up the Node service will hotswap every time there is a change in the src directory. If you make changes outside of this directory that would affect the microservice application, such as installing a new npm package, etc. you will need to rebuild the backend microservice application for this change to reflect.
docker-compose build api
If you modify anything related to the database or the Terraform for the Localstack configuration, you will need to restart the docker-compose environment for these changes to take effect (aka there is no hotswapping for anything outside of the Node application). This can be down by quitting the docker-compose process (if its running) via ctrl-c and then starting it back up with docker-compose up.
