Deploy with Snaps

As of December 15, 2023, Rocket.Chat has ceased support for connections from cloud services and official mobile/desktop apps to workspaces running legacy versions outside our support window. Users on unsupported legacy servers are advised to upgrade to the latest Rocket.Chat version to ensure continued access to cloud, mobile, and desktop applications. Each Rocket.Chat version is supported for six months post-release.

Snaps are a convenient way to rapidly deploy a Rocket.Chat instance for development or discovery purposes. We do not recommend snaps for managing production environment.

Installing software on Linux can be done easily with the use of Snaps. They are self-contained packages with all necessary files and dependencies, ensuring easy installation and updates. Deploying Rocket.Chat with Snaps offers seamless deployment on any Linux distribution, providing a secure and isolated workspace. It also auto-updates when a new version of Rocket.Chat is released.

In this guide, you'll learn how to:

• Deploy Rocket.Chat using Snap

• Backup and restore Rocket.Chat Snap data

• Auto SSL with Snaps

• Update Rocket.Chat Snap

Prerequisites

• A Linux-based system (Ubuntu, Debian, Fedora, etc.)

• AVX/AVX2 supported CPU to run Mongo 5.0 for Rocket.Chat workspaces on version 6.0 & above.

• Snap is pre-installed in most modern Linux distributions. If it's not, see the Snaps installation guide.

Deploy Rocket.Chat with Snaps

To install Rocket.Chat with snap on Ubuntu, run the following command:

sudo snap install rocketchat-server

This command installs the latest available version on Rocket.Chat. You can also specify the installation by track.

To access your Rocket.Chat workspace, open a web browser, and navigate to the specified ROOT URL (http://localhost:3000). Follow the configuration prompts to configure your workspace.

Move between major releases

With Snap tracks, you can smoothly transition between major releases of Rocket.Chat ( from 2.x to 3.x or from 3.x to 4.x). These tracks enable you to remain on a specific release while receiving updates exclusively for that particular track.

For instance, you can confidently switch to a new major release with the following command:

sudo snap switch rocketchat-server --channel=4.x/stable

Snap tracks allow you to keep your Rocket.Chat server up-to-date with the latest features while choosing your preferred release version.

Configure Rocket.Chat with Snaps

To see the list of snap variables to configure for your Rocket.Chat server, run the following command:

snap get rocketchat-server

It displays a list of values like this:

Key                Value
backup-on-refresh  disable
ignore-errors      false
mongo-oplog-url    mongodb://localhost:27017/local
mongo-url          mongodb://localhost:27017/parties
port               3000
siteurl            http://localhost:3000

To set any of the variables, run this command:

sudo snap set rocketchat-server <variable-name>=<value>

Configure MongoDB

From track 4.x, you can configure your MongoDB. The configuration file is located in /var/snap/rocketchat-server/current/mongod.conf. For all the configuration options, see MongoDB's official documentation.

Snap backup and restore

Snap backup and restore is a handy tool that allows you to create backups of your Rocket.Chat instance and restore them as needed.

Backup Rocket.Chat Snap data

Run the following command to enable automatic backup on each snap refresh:

sudo snap set rocketchat-server backup-on-refresh=enable

To backup the data on your snap installation, follow these steps:

1. Stop your rocketchat-server by running the command:

sudo service snap.rocketchat-server.rocketchat-server stop

While the rocketchat-server service should be stopped, the rocketchat-mongo service should be kept running. To verify this, run the following command:

sudo service snap.rocketchat-server.rocketchat-mongo status | grep Active
   Active: active (running) (...)

2. Execute the backup command:

sudo snap run rocketchat-server.backupdb

A successful backup will return this:

[+] A backup of your data can be found at /var/snap/rocketchat-server/common/backup/rocketchat_backup_<timestamp>.tar.gz

4. Start your rocketchat-server

sudo service snap.rocketchat-server.rocketchat-server start

5. Copy your backup to a different system for safekeeping.

Restore Rocket.Chat Snap data

To restore your backed-up snap data, follow these steps:

1. Stop your rocketchat-server by running this command:

sudo service snap.rocketchat-server.rocketchat-server stop

While the rocketchat-server service should be stopped, the rocketchat-mongo service should be kept running. To verify this, run the following command:

sudo service snap.rocketchat-server.rocketchat-mongo status | grep Active
   Active: active (running) (...)

2. Copy your backup file to the snap's common folder:

sudo cp rocketchat_backup.tgz /var/snap/rocketchat-server/common/

3. Run the restore command:

sudo snap run rocketchat-server.restoredb /var/snap/rocketchat-server/common/rocketchat_backup.tgz

If you are replacing an existing database, you get a warning message:

ATTENTION
Your current database WILL BE DROPPED prior to the restore!
Do you want to restore?
1) Yes
2) No

Choose your restore option. If it is successfully done, you will see an output similar to the following:

[*] Extracting backup file...
[*] Restoring data...
[*] Preparing database...
[+] Restore completed! Please restart the snap.rocketchat services to verify.

4. Start your rocketchat-server

sudo service snap.rocketchat-server.rocketchat-server start

Auto SSL with Snaps

Starting from release 0.73, the snap includes Caddy, which utilizes Let's Encrypt to enable TLS protection for your communications. Snap hooks ensure easy configuration of Caddy, including proper DNS setup, before starting Caddy with Let's Encrypt support.

To set up Auto SSL with Snaps for 4.x latest AMD64 snaps or 3 .x latest ARM64 snaps, follow these steps:

1. Set the SiteUrl to your domain using the following command, ensure it is prefixed with https:

sudo snap set rocketchat-server siteurl=https://<your domain>

2. Start Caddy and restart the snap services.

sudo systemctl enable --now snap.rocketchat-server.rocketchat-caddy 
sudo snap restart rocketchat-server

You can configure Caddy yourself or use another HTTP Proxy.

For 4.x latest AMD64 snaps or 3.x latest ARM64 snaps, follow these steps:

Both caddy v2 and caddy v1 (EOL) is delivered in the snap, v2 is prioritized over v1.

• To configure Caddy yourself, place the Caddyfile in the /var/snap/rocketchat-server/current/ directory and restart rocketchat-server.

sudo snap restart rocketchat-server

• To use another reverse proxy, disable Caddy by running this command:

sudo systemctl disable snap.rocketchat-server.rocketchat-caddy

For older snap versions

If you would like to use a different HTTPS proxy or prefer other options in your Caddy configuration, you can choose to disable Caddy by running this command:

sudo snap set rocketchat-server caddy=disable

1. Edit the Caddyfile found at /var/snap/rocketchat-server/current/Caddyfile and write your configuration.

2. Replace _caddy-url_ and _port_ with your site information. For example, suppose that you have example-domain.com directed toward your server.

   If your DNS is not working, you could be instantly throttled by Let's Encrypt for up to a week.

3. Be sure that your DNS has finished resolving before attempting to enable TLS. To test your DNS you can use http:

http://example-domain.com

reverse_proxy localhost:3000

4. Restart Caddy:

sudo systemctl reload snap.rocketchat-server.rocketchat-caddy

5. You can check that the Caddy service started correctly by running:

sudo systemctl status snap.rocketchat-server.rocketchat-caddy

6. Once that is tested and resolved, to get secured communications, you can remove the http://:

example-domain.com

reverse_proxy localhost:3000

Using an IP address will not work for automatically enabling TLS with a publicly-trusted certificate. You must use a valid hostname for a trusted certificate. See the official guide for more information.

If you use an IP address, Caddy will still serve your site over TLS, but using a self-signed certificate.

7. Restart the Caddy service by running:

sudo systemctl reload snap.rocketchat-server.rocketchat-caddy

8. You can check that the Caddy service started correctly by running:

sudo systemctl status snap.rocketchat-server.rocketchat-caddy

If the configuration is successful, the website should now be accessible at https://example-domain.com.

Update Rocket.Chat on Snap

Before you proceed, see the general guidelines for updating Rocket.Chat.

With the Rocket.Chat snap installation, you'll always be on the latest track at the setup time, ensuring access to the latest releases.

It is highly advised to back up your data before upgrading.

Before a major version update, check the forum's announcement section. Major releases are often delayed by a couple of weeks to gather feedback and apply minor patches before the final release.

To force an update, run this command:

sudo snap refresh rocketchat-server

To update to a major version, switch to a specific track by executing this command:

sudo snap switch rocketchat-server --channel=x.x/stable

You'll then receive updates related to that track.

Learn more about track changes in this discussion.

In addition to the latest track, Rocket.Chat offers three other channels: stable, candidate, and edge. For more information on these channels, refer to the official guide.

To update to a new version, execute this command:

sudo snap refresh rocketchat-server --channel=x.x/stable

The channel format is " x.x/stable," where the first "x" represents the major version, and the second "x" remains unchanged. For example, for major version 6, the channel is " 6.x/stable," and for major version 5, it's " 5.x/stable." In each " 6.x/stable" channel, you will receive all minor and patch release updates specifically for that major version (in this case, major version 6).
