Guides - Deploying Rocket.Chat through the Linode Marketplace

Rocket.Chat is a self-hosted open source chat application that can be used as an alternative to Slack. Rocket.Chat has many key features that you or your business can utilize to improve productivity in the workplace such as video conferencing, group chats, and platform integrations with some of the most popular applications.

Deploying a Marketplace App

The Linode Marketplace allows you to easily deploy software on a Compute Instance using the Cloud Manager. See Get Started with Marketplace Apps for complete steps.

1. Log in to the Cloud Manager and select the Marketplace link from the left navigation menu. This displays the Linode Create page with the Marketplace tab pre-selected.

2. Under the Select App section, select the app you would like to deploy.

3. Complete the form by following the steps and advice within the Creating a Compute Instance guide. Depending on the Marketplace App you selected, there may be additional configuration options available. See the Configuration Options section below for compatible distributions, recommended plans, and any additional configuration options available for this Marketplace App.

4. Click the Create Linode button. Once the Compute Instance has been provisioned and has fully powered on, wait for the software installation to complete. If the instance is powered off or restarted before this time, the software installation will likely fail.

To verify that the app has been fully installed, see Get Started with Marketplace Apps > Verify Installation. Once installed, follow the instructions within the Getting Started After Deployment section to access the application and start using it.

Note

Estimated deployment time: Rocket.Chat should be fully installed within 2-5 minutes after the Compute Instance has finished provisioning.

Configuration Options

• Supported distributions: Ubuntu 20.04 LTS
• Recommended plan: All plan types and sizes can be used.

Rocket.Chat Options

Limited User (Optional)

You can optionally fill out the following fields to automatically create a limited user for your new Compute Instance. This is recommended for most deployments as an additional security measure. This account will be assigned to the sudo group, which provides elevated permission when running commands with the sudo prefix.

• Limited sudo user: Enter your preferred username for the limited user.
• Password for the limited user: Enter a strong password for the new user.
• SSH public key for the limited user: If you wish to login as the limited user through public key authentication (without entering a password), enter your public key here. See Creating an SSH Key Pair and Configuring Public Key Authentication on a Server for instructions on generating a key pair.
• Disable root access over SSH: To block the root user from logging in over SSH, select Yes (recommended). You can still switch to the root user once logged in and you can also log in as root through Lish.

Custom Domain (Optional)

If you wish to access your application using a custom domain, fill out the following fields.

• Linode API Token: If you wish to use the Linode’s DNS Manager to manage DNS records for your custom domain, create a Linode API Personal Access Token on your account with Read/Write access to Domains. If this is provided along with the subdomain and domain fields (outlined below), the installation attempts to create DNS records via the Linode API. See Get an API Access Token. If you do not provide this field, you need to manually configure your DNS records through your DNS provider and point them to the IP address of the new instance.
• Subdomain: The subdomain you wish to use, such as www for www.example.com.
• Domain: The domain name you wish to use, such as example.com.

• Email address for the SOA record: The start of authority (SOA) email address for this server. This is a required field if you want the installer to create DNS records.

Getting Started after Deployment

Accessing the Rocket.Chat App

1. Open a browser and navigate to the domain you created in the beginning of your deployment. You can also use your Compute Instance’s rDNS, which will appear like 203-0-113-0.ip.linodeusercontent.com. See the Managing IP Addresses guide for information on viewing and setting the rDNS value.

2. From there, Rocket.Chat prompts you to fill out multiple forms to get your instance created and ready to use:

Now that you’ve gone through the setup and accessed your Rocket.Chat instance, check out the official Rocket.Chat documentation to learn how to further utilize your Rocket.Chat instance.

Note

Currently, Linode does not manage software and systems updates for Marketplace Apps. It is up to the user to perform routine maintenance on software deployed in this fashion.
