**Set up Discourse in the cloud in under 30 minutes** with zero knowledge of Rails or Linux shell using our [Discourse Docker image][dd]. We recommend [DigitalOcean][do], but these steps will work on any Docker-compatible cloud provider or local server.
Create your new Droplet. You will receive an email with the root password to your Droplet. (However, if you know [how to use SSH keys](https://www.google.com/search?q=digitalocean+ssh+keys), you may not need a password to log in.)
You will be asked for permission to connect, type `yes`, then enter the root password from the email DigitalOcean sent you when the server was set up. You may be prompted to change the root password, too.
- If you're using the minimum 1 GB install, you *must* [set up a swap file](https://meta.discourse.org/t/create-a-swapfile-for-your-linux-server/13880).
- If you're using 2 GB+ memory, you can probably get by without a swap file.
This command installs the latest versions of Docker and Git on your server. Alternately, you can manually install Git and the [Docker package for your OS](https://docs.docker.com/installation/).
- Set `DISCOURSE_DEVELOPER_EMAILS` to your email address.
- Set `DISCOURSE_HOSTNAME` to `discourse.example.com`, this means you want your Discourse available at `http://discourse.example.com/`. You'll need to update the DNS A record for this domain with the IP address of your server.
- Place your [Email Server credentials][mailconfig] in `DISCOURSE_SMTP_ADDRESS`, `DISCOURSE_SMTP_PORT`, `DISCOURSE_SMTP_USER_NAME`, `DISCOURSE_SMTP_PASSWORD`. Be sure you remove the comment `#` character and space from the front of these lines as necessary.
Please be careful while editing and double check your work; YAML is _very_ sensitive to incorrect spacing and misplaced characters. After completing your edits, press <kbd>Ctrl</kbd><kbd>O</kbd> then <kbd>Enter</kbd> to save and <kbd>Ctrl</kbd><kbd>X</kbd> to exit.
**Email is CRITICAL for account creation and notifications in Discourse. If you do not properly configure email before bootstrapping YOU WILL HAVE A BROKEN SITE!**
- Already have a mail server? Great. Use your existing mail server credentials.
If you need to change or fix your email settings after bootstrapping, you must edit the `app.yml` file again and `./launcher rebuild app`, otherwise your changes will not take effect. If you didn't receive an email from your install, read [Register New Account and Become Admin](#register-new-account-and-become-admin) for troubleshooting.
Your Discourse should be accessible in your web browser via the domain name `discourse.example.com` you entered earlier, provided you configured DNS. If not, you can visit the server IP directly, e.g. `http://192.168.1.1`.
There is a reminder at the top about the `DISCOURSE_DEVELOPER_EMAILS` you entered previously in `app.yml`; register a new account using one of those email addresses, and your account will automatically be made an Admin.
(If you *don't* get any email from your install, and are unable to register a new admin account, please check the logs at `/var/discourse/shared/standalone/log/rails/production.log` and see our [Email Troubleshooting checklist](https://meta.discourse.org/t/troubleshooting-email-on-a-new-discourse-install/16326).)
You should see Staff topics and **READ ME FIRST: Admin Quick Start Guide**. This guide contains the next steps for further configuring and customizing your Discourse install as an administrator. Read it closely!
(If you are still unable to register a new admin account via email, see [Create Admin Account from Console](https://meta.discourse.org/t/create-admin-account-from-console/17274), but please note that *you will have a broken site* unless you get email working on your instance.)
- Turn on automatic security updates for your OS. In Ubuntu use the `dpkg-reconfigure -plow unattended-upgrades` command.
- If you are using a password and not a SSH key, be sure to enforce a strong root password. In Ubuntu use the `apt-get install libpam-cracklib` package.
You will get email reminders as new versions of Discourse are released. Please stay current to get the latest features and security fixes. To **upgrade Discourse to the latest version**, visit `/admin/upgrade` in your browser and click the Upgrade button.
