realm-object-server | issues related to the Realm Object Server | Database library

I'm trying to build a Dockerfile based on the realm/realm-object-server image. To create a container with that image, I have to run the command:

$ docker run -p 9080:9080 -e ROS_TOS_EMAIL_ADDRESS="your-email-address" realm/realm-object-server

providing an email.

My Dockerfile starts:

FROM realm/realm-object-server:latest

how can I pass the ROS_TOS_EMAIL_ADDRESS environment variable to the FROM image? Otherwise it gives me an error later when executing the realm-object-server.

I am using Realm Object Server 1.8.3 manually installed from a .deb file (found on packagecloud.io) on my Ubuntu 16.10 and I would like to upgrade to a 2.x release (2.5.1 is the latest at the time of writing).

Unfortunately, packagecloud.io does not have 2.x packages (except some 2.0.0 release candidates and alpha versions) available and the installation instructions are using a different mechanism and do not integrate with systemd as far as I can tell.

Any hints on how to best do this or where to find a package?

Here I see what appear to be instructions for extending the ROS to be a web service. Server side access is called a pro feature in the pricing page https://realm.io/pricing#price-cards so are those functions only available in the pro edition?

I am trying to setup a Realm Object Server for my company's mobile application. I have to use a custom authentication to allow users to access the database.

I've recently tried to install Realm Object Server from NPM (I'm on macOS). I was used to the Realm Dashboard which was embedded in the "macOS Bundle" available for the 1.x version. It is unfortunately unavailable when attempting to reach http://localhost:9080.

There are now two things I think could be responsible for my issue:

1. This feature was only present in the 1.x version
2. This feature is not embedded in the NPM version

Please note that I'm using (or at least want to use) the Developer Edition.

I have been using ROS for a couple months now so I understand most of its functions but their subscription plans are very unclear because some features are supposed to be reserved to the Enterprise edition but on macOS you can temporarily have access to them for an unknown duration... Maybe what I'm looking for is no longer available ?

I would like to know more about how the temp folder on the Realm Object Server works so that I can delete files that aren't needed.

On my server, in var/lib/realm/object-server/tmp I have:

• 38 items (core.something) that are all 0 bytes from Monday August 21st.
• 272 items (core.something) that are 700mb - 3.5gb from Wednesday August 23rd.
• 1 file (core.something) that is 2.5gb from Sunday August 27th.
• 8 files (core.something) that are 1-3.5gb from Wednesday August 30th.
• 6 files (core.something) that are 1-3.4gb from Thursday August 31st.
• 9 files (core.something) that are 1-2.1gb from Friday September 1st.
• 2 files (core.something) that are 1-2.7gb from Monday September 4th.
• realm-object-server folder with folders from Aug 11th through September 4th.

My question is if I can delete anything off out of this folder. There are giant gaps in the days that these files dates say, and especially the ones from August 23rd are taking up 342gb of space on the server. If these are outdated, is there something that will automatically remove these files, or will it hurt anything if I remove them?

It is very confusing how there is so much data being stored on the server and so little data (comparatively) being transferred in/out from the server.

(side note: we were mistakenly storing images in the realms and have since switched to storing them on devices and storing the urls, but we haven't migrated the realms that were storing photos, so they still are, but all new realms will only store references. that's why there is so much bloat. but I don't see any documentation on manually clearing out the temp files or if that is something that is done automatically, when that should be done to make sure that it is working properly.)

I'm running the developers edition of Realm Object Server v1.8.3 as a mac app. I start it with the start-object-server.command. It has been running fine for a number of days and everything was working really well, but ROS is now crashing within seconds of starting it.

Clearly the issue is with the JavaScript element, but I am not sure what has led to this position, nor how best to recover from this error. I have not created any additional functions, so not adding any NODE.js issues: it's just ROS with half a dozen realms.

The stack dump I get from the terminal session is as below. Any thoughts on recovery steps and how to prevent it happening again would be appreciated.

I am using Realm Object Server running on Digital Ocean the lowest option ($5/month) on Ubuntu server. I keep getting connection refused errors; and I don't know if the error is from DO or ROS.

I am no expert on Ubuntu; therefore, I went in and cleared all the logs from /var/log and tried to reconnect. When there are large records to sync I keep getting the following error (on iOS, the client side):

I'm still learning how to implement realm.io in my next project. I'm really amazed in the Realm Mobile Platform (offline-sync).

I'm reading https://realm.io/docs/realm-object-server/#access-control but what I need is preventing user accessing certain data in a model. (let's say they only can access data only their own data).

Thank You
