**Note**: You might want to jump ahead to the section about Continuous Deployment with GitHub Actions.
## Copy the Code
```bash
rsync -av --filter=":- .gitignore" ./ root@your-server.example.com:/root/code/app/
```
Note: `--filter=":- .gitignore"` tells `rsync` to use the same rules as git, ignore files ignored by git, like the Python virtual environment.
## Environment Variables
You need to set some environment variables first.
Set the `ENVIRONMENT`, by default `local` (for development), but when deploying to a server you would put something like `staging` or `production`:
```bash
export ENVIRONMENT=production
```
Set the `DOMAIN`, by default `localhost` (for development), but when deploying you would use your own domain, for example:
```bash
export DOMAIN=fastapi-project.example.com
```
You can set several variables, like:
* `PROJECT_NAME`: The name of the project, used in the API for the docs and emails.
* `STACK_NAME`: The name of the stack used for Docker Compose labels and project name, this should be different for `staging`, `production`, etc. You could use the same domain replacing dots with dashes, e.g. `fastapi-project-example-com` and `staging-fastapi-project-example-com`.
* `BACKEND_CORS_ORIGINS`: A list of allowed CORS origins separated by commas.
* `SECRET_KEY`: The secret key for the FastAPI project, used to sign tokens.
* `FIRST_SUPERUSER`: The email of the first superuser, this superuser will be the one that can create new users.
* `FIRST_SUPERUSER_PASSWORD`: The password of the first superuser.
* `SMTP_HOST`: The SMTP server host to send emails, this would come from your email provider (E.g. Mailgun, Sparkpost, Sendgrid, etc).
* `SMTP_USER`: The SMTP server user to send emails.
* `SMTP_PASSWORD`: The SMTP server password to send emails.
* `EMAILS_FROM_EMAIL`: The email account to send emails from.
* `POSTGRES_SERVER`: The hostname of the PostgreSQL server. You can leave the default of `db`, provided by the same Docker Compose. You normally wouldn't need to change this unless you are using a third-party provider.
* `POSTGRES_PORT`: The port of the PostgreSQL server. You can leave the default. You normally wouldn't need to change this unless you are using a third-party provider.
* `POSTGRES_PASSWORD`: The Postgres password.
* `POSTGRES_USER`: The Postgres user, you can leave the default.
* `POSTGRES_DB`: The database name to use for this application. You can leave the default of `app`.
* `SENTRY_DSN`: The DSN for Sentry, if you are using it.
## GitHub Actions Environment Variables
There are some environment variables only used by GitHub Actions that you can configure:
* `LATEST_CHANGES`: Used by the GitHub Action [latest-changes](https://github.com/tiangolo/latest-changes) to automatically add release notes based on the PRs merged. It's a personal access token, read the docs for details.
* `SMOKESHOW_AUTH_KEY`: Used to handle and publish the code coverage using [Smokeshow](https://github.com/samuelcolvin/smokeshow), follow their instructions to create a (free) Smokeshow key.
### Generate secret keys
Some environment variables in the `.env` file have a default value of `changethis`.

Copy the content and use that as password / secret key. And run that again to generate another secure key.
### Required Environment Variables
Set the `ENVIRONMENT`, by default `local` (for development), but when deploying to a server you would put something like `staging` or `production`:
```bash
export ENVIRONMENT=production
```
Set the `DOMAIN`, by default `localhost` (for development), but when deploying you would use your own domain, for example:
```bash
export DOMAIN=fastapi-project.example.com

Set the `POSTGRES_PASSWORD` to something different than `changethis`:
```bash
export POSTGRES_PASSWORD="changethis"
```
Set the `SECRET_KEY`, used to sign tokens:
```bash
export SECRET_KEY="changethis"
```
Note: you can use the Python command above to generate a secure secret key.
Set the `FIRST_SUPER_USER_PASSWORD` to something different than `changethis`:
```bash
export FIRST_SUPERUSER_PASSWORD="changethis"
```
Set the `BACKEND_CORS_ORIGINS` to include your domain:
```bash
export BACKEND_CORS_ORIGINS="https://dashboard.${DOMAIN?Variable not set},https://api.${DOMAIN?Variable not set}"

```bash
cd /root/code/app/
docker compose -f compose.yml build
docker compose -f compose.yml up -d
