**Set up Discourse on a cloud server in under 30 minutes** with zero knowledge of Ruby, Rails or Linux shell using our [Discourse Docker image][dd]. We prefer [Digital Ocean][do], although these steps may work on other cloud providers that also support Docker. Let's begin!

# Create New Digital Ocean Droplet

[Sign up for Digital Ocean][do], update billing info, then begin creating your new cloud server (Droplet).

Use the URL of your new site as the Droplet hostname, e.g. `discourse.example.com`. Discourse requires a minimum of **1 GB RAM** for small communities; we recommend 2 GB RAM for medium communities.

<img src="http://www.discourse.org/images/install/droplet-step-1.png" width="670" height="489">

Install Discourse on Ubuntu 14.04 LTS x64. Always select [the latest LTS distribution][lts].

<img src="http://www.discourse.org/images/install/droplet-step-2.png" width="540" height="478">

You will receive a mail from Digital Ocean 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.)

# Access Your Droplet

Connect to your Droplet via SSH, or use [Putty][put] on Windows:

    ssh root@192.168.1.1

Replace `192.168.1.1` with the IP address of your Droplet.

<img src="http://www.discourse.org/images/install/ssh-login-start.png" width="586" height="128">

You will be asked for permission to connect, type `yes`, then enter the root password from the email Digital Ocean sent you when the Droplet was set up. You may be prompted to change the root password, too.

# Set up Swap (if needed)

- 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.

# Install Git

    apt-get install git

<img src="http://www.discourse.org/images/install/install-git.png" width="586" height="293">

# Install Docker

    wget -qO- https://get.docker.io/ | sh

<img src="http://www.discourse.org/images/install/wget-docker.png" width="586" height="452">

# Install Discourse

Create a `/var/docker` folder, clone the [Official Discourse Docker Image][dd] into it, and make a copy of the config file as `app.yml`:

    mkdir /var/docker
    git clone https://github.com/discourse/discourse_docker.git /var/docker
    cd /var/docker
    cp samples/standalone.yml containers/app.yml

<img src="http://www.discourse.org/images/install/mkdir-var-docker.png" width="586" height="246">

# Edit Discourse Configuration

Edit the Discourse configuration at `app.yml`:

    nano containers/app.yml

We recommend Nano because it works like a typical GUI text editor, just use your arrow keys.

- 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 mail credentials 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.

- If you are using a 1 GB instance, set `UNICORN_WORKERS` to 2 so you have more memory room.

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 Important

**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.

- No existing mail server, or you don't know what it is? No problem, create a free account on [**Mandrill**][man] (or [Mailgun][gun], or [Mailjet][jet]), and use the credentials provided in the dashboard.

- For proper email deliverability, you must set the [SPF and DKIM records](http://help.mandrill.com/entries/21751322-What-are-SPF-and-DKIM-and-do-I-need-to-set-them-up-) in your DNS. In Mandrill, that's under Sending Domains, View DKIM/SPF setup instructions.

# Bootstrap Discourse

Save the `app.yml` file, and begin bootstrapping Discourse:

    ./launcher bootstrap app

This command takes about 8 minutes. It is automagically configuring your Discourse environment.

<img src="http://www.discourse.org/images/install/launcher-start-app.png" width="593" height="229">

After that completes, start Discourse:

    ./launcher start app

Congratulations! You now have your own instance of Discourse!

It should be accessible via the domain name `discourse.example.com` you entered earlier, provided you configured DNS. If not, you can also visit the server IP directly, e.g. `http://192.168.1.1`.

# Register New Account and Become Admin

There is a reminder at the top about `DISCOURSE_DEVELOPER_EMAILS`; register a new account via 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 see our [Email Troubleshooting checklist](https://meta.discourse.org/t/troubleshooting-email-on-a-new-discourse-install/16326).)

<img src="http://www.discourse.org/images/install/discourse-installed.png" width="690" height="350">

You should see Staff topics and the [Admin Quick Start Guide](https://github.com/discourse/discourse/blob/master/docs/ADMIN-QUICK-START-GUIDE.md). It contains the next steps for further configuring and customizing your Discourse install.

(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.)


# Post-Install Maintenance

To **upgrade Discourse to the latest version**, visit `/admin/docker` and follow the instructions.

The `launcher` command in the `/var/docker` folder can be used for various kinds of maintenance:

```
Usage: launcher COMMAND CONFIG [--skip-prereqs]
Commands:
    start:      Start/initialize a container
    stop:       Stop a running container
    restart:    Restart a container
    destroy:    Stop and remove a container
    enter:      Use nsenter to enter a container
    ssh:        Start a bash shell in a running container
    logs:       Docker logs for container
    mailtest:   Test the mail settings in a container
    bootstrap:  Bootstrap a container for the config based on a template
    rebuild:    Rebuild a container (destroy old, bootstrap, start new)
```
