Once you have it, you can install and compile all dependencies by running:
mix do deps.get, deps.compile
Finally, you are able to build the project itself like:
mix compile
Ensure you have PostgreSQL available on your machine. You can use either a local installation or a Docker distribution.
The application requires to have a user (role) postgres created with the same password on your localhost under 5432 port.
Later on, create and migrate your database with
mix ecto.setup
To start the application Phoenix server, run:
mix phx.server
Now you can visit localhost:4000 from your browser.
To prepare you application for production, you can use Dockerfile for that. It will require you have Docker installed locally.
To build a Docker image, execute the following command:
docker build . -t chatex:latest
Once built, you are able to push it to a remote repository as:
docker push chatex:latest
It assumes you are authorized and logged in to a Docker registry.
From the deployment options, you can choose for example:
Depending on your needs and complexity of your application.
