# Step by step instructions:

1. Copy the [.env.example](https://github.com/twentyhq/twenty/blob/main/packages/twenty-server/.env.example) into a `.env` in the same directory where your `docker-compose.yml` file will be
2. Run the command `openssl rand -base64 32` three times, make note of the string for each
3. In your .env file, replace the three "replace_me_with_a_random_string_access" with the three random strings you just generated.

```
ACCESS_TOKEN_SECRET=replace_me_with_a_random_string_access 
LOGIN_TOKEN_SECRET=replace_me_with_a_random_string_login 
REFRESH_TOKEN_SECRET=replace_me_with_a_random_string_refresh
```

4. Create a `docker-compose.yml` file from the example below.
5. Run the command `docker-compose up -d`
6. Go to http://localhost:3001 and see your docker instance.

## Troubleshooting 

### Not able to login 

If you encounter errors, (not able to log into the application after inputting an email) after the inital setup, try running `docker exec -it twenty-backend-1 yarn database:reset` and see if that solves your issue. 

### Cannot connect to server, running behind a reverse proxy

Complete step three and four with : 

3. Add `SERVER_URL=https://<your-api-url.com>` to your `.env`
4. Uncomment `SERVER_URL=${SERVER_URL}` in your `docker-compose.yml`

## Production docker containers

Prebuilt images for both Postgres, frontend, and back-end can be found on [docker hub](https://hub.docker.com/r/twentycrm/). Note that the Postgres container will not persist data if your server is not configured to be stateful (for example Heroku). You probably want to configure a special stateful resource for the database.

## Environment Variables

- Copy this `.env.example` file into a `.env` in the same directory as your `docker-compose.yml` file
- Find the `.env.example` [here](https://github.com/twentyhq/twenty/blob/main/packages/twenty-server/.env.example).

## Docker Compose file

We will soon update the documentation with an up-to-date docker compose file.
Here is one that was proposed on Discord by a community member:


```yaml
