Development

Install the dependencies:

This project uses Go mod, the official module manager, to handle Go modules in a portable way without having to worry about GOPATH.

go mod download
go mod vendor
go mod verify

Define environment variables for your development environment:

These are passed to the Docker container via docker-compose.yaml in development. When running in production, the environment variables must be passed to the container when it is run.

cp .env.example .env

Run locally:

This builds the Docker image and runs it automatically with the config defined in docker-compose.yaml. This saves you having to build the docker image and then run a manual docker run command with all the flags (for environment variables, ports, etc).

Local

task wire && air

Using Docker

docker compose up --build --remove-orphans app-dev

Production

Note: Environment variables are never baked into the image, or they wouldn't be environment variables. The production environment will start a Docker container based on this image, but it will have to pass the environment variables to the container when it runs it.

Example manually running a container with environment variables and ports defined: Using Docker

docker compose up --build --remove-orphans app
