# FastAPI Project - Deployment
You can deploy the project using Docker Compose in a remote server.
It expects you to have a Traefik proxy handling communication to the outside world and HTTPS certificates.
And you can use CI (continuous integration) systems to deploy automatically.
But you have to configure a couple things first.
## Preparation
* Have a remote server ready and available.
* Configure the DNS records of your domain to point to the IP of the server you just created.
* Install and configure [Docker](https://docs.docker.com/engine/install/).
* Create a remote directory to store your code, for example:
```bash
mkdir -p /root/code/fastapi-project/
```
## Public Traefik
We need a Traefik proxy to handle incoming connections and HTTPS certificates.
### Traefik Docker Compose
Copy the Traefik Docker Compose file to your server, to your code directory. You could do it with `rsync`:
```bash
rsync -a docker-compose.traefik.yml root@your-server.example.com:/root/code/fastapi-project/
```
### Traefik Public Network
This Traefik will expect a Docker "public network" named `traefik-public` to communicate with your stack(s).
This way, there will be a single public Traefik proxy that handles the communication (HTTP and HTTPS) with the outside world, and then behind that, you could have one or more stacks.
To create a Docker "public network" named `traefik-public` run:
```bash
docker network create traefik-public
```
### Traefik Environment Variables
The Traefik Docker Compose file expects some environment variables to be set.
Create the environment variables for HTTP Basic Auth.
* Create the username, e.g.:
```bash
export USERNAME=admin
```
* Create an environment variable with the password, e.g.:
```bash
export PASSWORD=changethis
```
* Use openssl to generate the "hashed" version of the password and store it in an environment variable:
```bash
export HASHED_PASSWORD=$(openssl passwd -apr1 $PASSWORD)
```
* Create an environment variable with the domain name, e.g.:
```bash
export DOMAIN=fastapi-project.example.com
```
* Create an environment variable with the email for Let's Encrypt, e.g.:
```bash
export EMAIL=admin@example.com
```
### Start the Traefik Docker Compose
Now with the environment variables set and the `docker-compose.traefik.yml` in place, you can start the Traefik Docker Compose:
```bash
docker compose -f docker-compose.traefik.yml up -d
```
## Deploy the FastAPI Project
Now that you have Traefik in place you can deploy your FastAPI project with Docker Compose.
You could configure the variables in the `.env` file to match your domain, or you could override them before running the `docker compose` command.
For example:
```bash
export DOMAIN=fastapi-project.example.com
```
And then deploy with Docker Compose:
```bash
docker compose -f docker-compose.yml up -d
```
For production you wouldn't want to have the overrides in `docker-compose.override.yml`, so you would need to explicitly specify the file to use, `docker-compose.yml`.
