Step 2Choose an app template
Click New App and choose the template deployment path so Server Compass can load the built-in catalog.
3
Step 3Search for Roundcube
Use the template picker search to find Roundcube in the Server Compass template catalog.
4
Step 4Select the Roundcube template
Choose the Roundcube template. Server Compass fills in the webmail service, IMAP host, SMTP host, MySQL database password, and root password.
5
Step 5Review the Roundcube settings
Confirm the app name and compose services. In this run, the app was named roundcube-demo and used host port 4201.
6
Step 6Deploy Roundcube
Review the generated environment values, confirm the port is available, and click Deploy Now.
7
Step 7Watch the deployment progress
Keep the deployment modal open while Server Compass uploads the compose file, pulls the Roundcube image, starts MySQL, initializes the webmail files, and verifies the stack.
8
Step 8Confirm Roundcube is running
After deployment finishes, return to the Apps tab and confirm the Roundcube app is marked Running with its application URL available.
9
Step 9Open Roundcube in the browser
Open the application URL in a browser. The Roundcube login UI confirms the webmail client is reachable.
After Roundcube Opens
- Replace the placeholder IMAP_HOST and SMTP_HOST values with your real mail server settings.
- Use ssl://host:993 or tls://host:587 style host strings when your mail server requires encrypted connections.
- Configure HTTPS before exposing Roundcube publicly.
- Back up the MySQL and Roundcube web data volumes because they store preferences, contacts, and drafts.
Verified Result
The Roundcube webmail login page loaded successfully in a browser.
Roundcube deployment questions
What does the Roundcube template deploy?
It deploys Roundcube with MySQL as a browser webmail front end for an existing IMAP and SMTP mail server.
Which port did the tutorial use?
The tutorial used host port 4201, which maps to the Roundcube web service on container port 80.
Why does the guide stop at the login page?
Roundcube is a mail client. The tutorial verifies that the login page loads; real mailbox login depends on the IMAP and SMTP server you configure.
Should this become a blog post?
No. The deployment guide should live on the Roundcube template detail page and be linked from the reusable template deployment docs page.
After Deployment
After deploying Roundcube with Server Compass, complete these steps to finish setup
1
Visit http://YOUR_SERVER_IP:{{PORT}} and log in with an email account hosted on {{IMAP_HOST}}
2
If login fails, double-check `ROUNDCUBEMAIL_DEFAULT_HOST` and `ROUNDCUBEMAIL_SMTP_SERVER` in the compose file - use `ssl://host:993` or `tls://host:587` syntax for encrypted connections
3
Customize the appearance and plugins by editing `/var/www/html/config/config.inc.php` (or mounting a custom config file)
4
Configure HTTPS in front of Roundcube before exposing it publicly
