Need higher version of Mongodb

[ChristopherMag]

We have an internal application that uses the mongodb addon and I recently was adding a feature that needed the $dateAdd function in mongodb and was happy to see that Cloudron 7.6 had mongo 5 so I upgraded and things have been working well.

I am now adding features again and need to use the $concatArray function which was added in version 5.2. Looking at their documentation it looks like MongoDB calls 5.X versions rapid releases and does not support those being run on premise.

I am guessing there is a non technical motivation behind MongoDB not supporting minor versions to be run on premise like pushing customers to their cloud offerings. I see that they don't offer docker containers for minor versions of the database and googling didn't turn up anyone else building it from source and packaging these minor version releases.

I have started exploring how difficult it will be to switch to using the postgresql addon with the same documents that were in mongo stored in a jsonb column but if there were plans to get to mongodb 6 or higher then I might not need to go down that path depending on how far out that is.

Is there a specific reason for using version 5 of mongo in the mongo addon instead of the latest stable release, which I believe is 6.0.7?

@ChristopherMag yes, my understanding was that one cannot jump from mongodb 4 to 6 directly . You have to go via 5. Next release of Cloudron will have mongodb 6.

For example, see https://www.mongodb.com/community/forums/t/mongodb-upgrade-from-4-2-and-4-4-to-6-0/205176

"To upgrade an existing MongoDB deployment to 6.0, you must be running a 5.0-series release.

To upgrade from a version earlier than the 5.0-series, you must successively upgrade major releases until you have upgraded to 5.0-series. For example, if you are running a 4.4-series, you must upgrade first to 5.0 before you can upgrade to 6.0."

Nice, ok so 5 was a transitionary step and the plan is to go to 6, great to hear!

When you say the next release of cloudron, are you referring to 7.7 or 8?

Cloudron 8 will have it.
