Docker

You can use Docker to create an image of your Alchemy app that will be deployable anywhere Docker is installed.

​

Create a Dockerfile

You’ll need a Dockerfile to deploy with Docker. This is a file that tells Docker how to build & run an image with your server.

If you created an Alchemy app with the installer script, a Dockerfile is already included in your project.

If you didn’t, here’s one that you can use.

​

Build an Image

Once that’s done, build an image of your app. This may take a moment.

docker build -t my-app:latest .

​

Run a Container

Finally, run the built image in a container. The -d flag tells Docker to run your container in the background and -p 3000:3000 tells it to bind it to localhost:3000.

docker run -d -p 3000:3000 my-app:latest

Visit http://localhost:3000 in the browser and you’ll see your app running. Nicely done!

​

Docker Compose

Docker Compose helps you start multiple containers at once defined in a docker-compose.yml file.

Again, if you created an Alchemy app with the installer script a docker-compose.yml are already included in your project.

If you didn’t, here’s a simple one that you can use. It runs three services based on your project - an app that serves to localhost:3000, a scheduler, and a queue worker.

Once you’ve created a docker-compose.yml file, you can easily start all three of these services in separate docker containers. Like before, the -d flag runs it in the background.

docker compose up -d

Shutting all three of them down is just as simple.
