**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.
Install Discourse on Ubuntu 14.04 LTS x64. Always select [the latest LTS distribution][lts].
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.
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
# Install Docker
wget -qO- https://get.docker.io/ | sh
# Install Discourse
Create a `/var/docker` folder:
mkdir /var/docker
Clone the [Official Discourse Docker Image][dd] into this `/var/docker` folder:
git clone https://github.com/discourse/discourse_docker.git /var/docker
Switch to your Docker folder:
cd /var/docker
Copy the `samples/standalone.yml` file into the `containers` folder as `app.yml`:
cp samples/standalone.yml containers/app.yml
# 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 CtrlO then Enter to save and CtrlX 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
Be sure to save the `app.yml` file, and begin bootstrapping Discourse:
./launcher bootstrap app
This command can take up to 8 minutes. It is automagically configuring your Discourse environment.
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`; be sure you register a new account via one of those email addresses, and your account will automatically be made an Admin.
You should see Staff topics and the Admin Quick Start Guide. Please read it!
# 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
Commands:
start: Start/initialize a container
stop: Stop a running container
restart: Restart a container
destroy: Stop and remove a container
ssh: Start a bash shell in a running container
logs: Docker logs for container
bootstrap: Bootstrap a container for the config based on a template
rebuild: Rebuild a container (destroy old, bootstrap, start new)
```
