Where Can I Deploy Discourse?

10 minutes read

Discourse can be deployed on various platforms and environments based on your requirements. Here are some common options:

  1. Self-hosted: You can deploy Discourse on your own servers or virtual machines. This gives you complete control over the installation, customization, and maintenance of Discourse. It requires technical expertise but offers extensive flexibility.
  2. Cloud platforms: Discourse can be deployed on popular cloud platforms such as Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure. These platforms provide scalable infrastructure and managed services, making it easier to deploy and maintain Discourse.
  3. Docker: Discourse provides an official Docker image that allows you to deploy it using containerization technology. Docker simplifies the installation process and provides isolation between Discourse and other applications on the server.
  4. specialized hosting providers: Some hosting providers specialize in hosting Discourse. They offer optimized environments, automatic updates, and dedicated support for Discourse installations. Examples include DiscourseHosting and Civilized Discourse Construction Kit.

Before choosing a deployment method, consider factors such as your technical expertise, scalability requirements, available resources, and desired level of customization and control.

How to deploy Discourse on a shared hosting provider?

Deploying Discourse on a shared hosting provider can be a bit challenging as it was designed to run on dedicated servers or cloud-based VPS. However, it is still possible to install Discourse on a shared hosting provider by utilizing Docker and following these steps:

  1. Ensure that your shared hosting provider supports Docker and has it installed. If Docker is not available, you may need to switch to a different hosting provider.
  2. Set up a Docker container for Discourse. Connect to your shared hosting server via SSH and run the following command to create a Docker container for Discourse: docker run --detach --name discourse --hostname example.com \ --publish 80:80 --publish 443:443 \ --restart always \ --volume /var/discourse/shared/standalone:/shared \ discourse/discourse:latest
  3. Replace example.com with your actual domain name or IP address. This command will create a container named discourse and bind it to ports 80 and 443 for HTTP and HTTPS traffic.
  4. Configure your DNS settings to point your domain or subdomain to your shared hosting server's IP address.
  5. Wait for a few minutes to allow the container to initialize and set up Discourse properly.
  6. Access your Discourse forum by visiting http://example.com in your web browser, replacing example.com with your actual domain or subdomain.

Note: Keep in mind that shared hosting providers often have resource limitations, and hosting Discourse on such platforms may result in limited performance or functionality. It's recommended to use a VPS or dedicated server for optimal Discourse performance.

Shared hosting plans typically range from around $2 to $20 per month, although some providers may offer higher-priced plans with more resources. It's important to note that Discourse is a resource-intensive application, so it may not be suitable for all shared hosting environments. Additionally, some hosting providers may not support hosting Discourse due to its specific requirements. It's recommended to check with different hosting providers for their pricing and compatibility with hosting Discourse.

What is the deployment process for Discourse on DigitalOcean?

The deployment process for Discourse on DigitalOcean can be divided into several steps as follows:

  1. Create a DigitalOcean Droplet: Sign in to your DigitalOcean account, create a new Droplet, and select the desired server size, region, and other specifications.
  2. Set up DNS: Once the Droplet is created, associate a domain name with it by adding an "A" record pointing to the Droplet's IP address. This can be done through your domain registrar or DNS provider.
  3. Configure DNS on DigitalOcean: In the DigitalOcean control panel, navigate to the Networking section and add your domain name. Then, create two DNS records: an "A" record with "@" as the hostname and your Droplet's IP address, and a "CNAME" record with "www" as the hostname and "@" as the value.
  4. Access the Droplet: Open a terminal or SSH client and connect to your Droplet using the IP address and the root credentials provided by DigitalOcean.
  5. Install Docker and Git: In the Droplet, run the following commands to install Docker and Git:
$ wget -qO- https://get.docker.com/ | sh
$ apt-get install -y git

  1. Clone the Discourse repository: Use Git to clone the Discourse repository onto the Droplet:
$ git clone https://github.com/discourse/discourse.git /var/discourse

  1. Configure Discourse: Move to the Discourse directory and copy the sample configuration file:
$ cd /var/discourse
$ cp samples/standalone.yml containers/app.yml

Edit the app.yml file with your preferred settings, such as domain name, email address, and other options.

  1. Bootstrap Discourse: Run the following command to install all the required dependencies and bootstrap Discourse:
$ ./launcher bootstrap app

  1. Start Discourse: Once the bootstrap process completes, start Discourse with the following command:
$ ./launcher start app
