Rocket.Chat is a fully customizable communications platform for organizations with high standards of data protection. It enables real-time conversations between colleagues, with other companies or with your customers, regardless of how they connect with you. In this step by step guide I will show you how to install Rocket.Chat on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest Rocket.Chat 7.8.1 release.

⚠️ WARNING: Rocket.Chat is evolving and MongoDB 4.0 will be deprecated. MongoDB 6 requires a CPU with AVX support.
Unsupported NAS Models (that don’t support MongoDB 6): DS218+ DS718+ DS220+ DS720+ DS920+ and older consumer models. You can always run Rocket.Chat with an older mongo version, but there is no guarantee that Rocket.Chat will continue to work with older Mongo versions. To install Rocket.Chat with MongoDB 4 in unsupported NAS models, read the “Warning” note at STEP 17. Remember, there is no guarantee that rocketchat will work with older NAS models. After running extensive tests it has resulted that only the 18+ series NAS works with the older MongoDB 4. The NAS models that DO NOT support Rocket.Chat at all due to hardware limitations are the 20+ series like the DS220+, DS720+, DS920+, DS1520+.
Supported NAS Models (that support MongoDB 6): All NAS models from the 21+, 22+, 23+ 24+ series.
Note: It’s a possibility that older NAS devices have AVX support. Check your NAS CPU to see if it supports AVX.
What is MongoDB? MongoDB is a database. Classified as a NoSQL database program, MongoDB uses JSON-like documents with optional schemas.

Warning: As I explained at the beginning of this article, if your NAS CPU does not have AVX support, in the code above type in mongodb:4.4 instead of mongodb:7.0.5-debian-11-r22 After running extensive tests it has resulted that only the 18+ series NAS works with the older MongoDB 4. The NAS models that DO NOT support Rocket.Chat at all due to hardware limitations are the 20+ series like the DS220+, DS720+, DS920+, DS1520+.

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.
