### Building and running your application
2+
3+
When you're ready, start your application by running:
4+
`docker compose up --build`.
5+
6+
Your application will be available at http://localhost:8080.
7+
8+
### Deploying your application to the cloud
9+
10+
First, build your image, e.g.: `docker build -t myapp .`.
11+
If your cloud uses a different CPU architecture than your development
12+
machine (e.g., you are on a Mac M1 and your cloud provider is amd64),
13+
you'll want to build the image for that platform, e.g.:
14+
`docker build --platform=linux/amd64 -t myapp .`.
15+
16+
Then, push it to your registry, e.g. `docker push myregistry.com/myapp`.
17+
18+
Consult Docker's [getting started](https://docs.docker.com/go/get-started-sharing/)
19+
docs for more detail on building and pushing.
