I am running mongo docker image that I pulled from docker hub mongo image It works ok but when I start Robomongo I cannot connect to localhost. With following error message: Cannot connect to the MongoDB at localhost:27017. Error: Network is unreachable I appreciate any help, thanks. EDIT: I solved the issue by using the following command: docker run -p 27017:27017 --name mongo_instance_001 -d mongo Don't forget to map port to host port: docker run --name some-mongo -p 27017:27017 -d mongo Then docker-machine ip gives me 192.168.99.100 Type in terminal mongo 192.168.99.100 prints MongoDB shell

I'm in this scenario right now: I have a collection X: { _id:ObjectId('56edbb4d5f084a51131dd4c6'), userRef:ObjectId('56edbb4d5f084a51131dd4c6'), serialNumber:'A123123', ... } I need to aggregate all documents, grouping them by the userRef + serialNumber, so I'm trying to use concat like this: $group: { _id: { '$concat': ['$userRef','-','$serialNumber'] }, ... So basically in my aggregation in MongoDB, I need to group documents by the concatenation of a ObjectId and a string. However, It seems that $concat only accepts strings as parameters: uncaught exception: aggregate failed: { "errmsg" :

How do I fix this? I am using Robo 3T Version 1.1 I tried same with Robomongo 1.0, and still getting the same error Just change your bind_ip in /etc/mongod.conf from 127.0.0.1 to 0.0.0.0 then restart the service, and it works for me~ If you get the following error then

So I do not know much about MongoDB . I have RoboMongo using which I connect to a MongoDB. What I need to do is this - there is a collection in that MongoDB. I want to export the data from that collection so that I can save it into a file. I used the interface to open the data from the collection as text and did a CTRL + A and pasted into a text file. However I found that not all data is copied and also that there were many comments in the text data which naturally breaks the JSON. I am wondering if RoboMongo has a Export As JSON facility so that I can do a clean export. Any pointers are

I have created a MongoDB instance in OpenShift . I can connect to it via RockMongo , which is a service offered by OpenShift . I'm trying to connect to my instance using JAVA , but I just receive a Connection refuesed error. Moreover, I cannot connect it using RoboMongo .

In my JAVA app I'm trying the following: MongoCredential credential =
