Backing up MongoDBīacking up MongoDB requires a somewhat circuitous process. You can exit less by hitting "q" or CTRL-C. In which case, you can look at the log file to see what's gone wrong: Which will give you a result like this (your filenames will be different): Which will drop you at the command line in the container. ID=`docker ps | grep mongo | cut -characters=1-12` You can even log into the container and poke around the filesystem if you like, using the container's "id": You should be able to check it's running by typingĪnd looking for the reference to "mongodb" (that's the "name" we've assigned to this instance of the "mongo" container). v /home/mongo/data:/data/db -v /home/mongo/backups:/backups -d mongo -smallfiles We can create "data" and "backups" directories in which it should store its data and save its backups respectively:ĭocker run -name mongodb -restart unless-stopped \

This creates a directory /home/mongo and that's where we'll get the Mongo container to store the data we want to keep persistent. I recommend setting up a per-container user to help keep things well segmented. This will install the latest version of the MongoDB container from docker.io. Once you've got Docker working on your virtual machine, getting the MongoDB docker container (where it's preinstalled and ready to go) is simple: You simply re-launch the container making sure it points properly to the persistent stuff you want it to use.
DOCKER INSTALL MONGO EXAMPLE UPGRADE
You can do that to quickly upgrade it, or to change its properties. That means that you can blow it away at any time without losing any important data.

Note: the idea with Docker is that nothing important is stored in the container itself. Once you've got a working Docker container install going on your server, you can continue to the next step. It also covers installing on other versions of Ubuntu which might be helpful for some. Rather than trying to write a comprehensive guide to installing Docker, I'll instead recommend that you have a look at this one provided by the Docker community. The motivation for installing MongoDB is that it is the key-value based data container engine used by two compelling web technologies, Rocket.Chat and Wekan, that the OER Foundation has deployed for the OERu as and. (Update: we've just published an easier way to run MongoDB and Rocket.Chat and Wekan which depend on it) This post describes installing MongoDB (and backing it up and restoring from backup) in a Docker container on an Ubuntu Linux 14.04 virtual machine. Optionally, if you want to build your own version of the image, and for example additionally install mongo-hacker shell enhancement, in your docker-compose.yml file you can replace image: mongo:latest with build.

The default mongo image command to start mongod service is just mongod, which does not use the /etc/nf configuration file. Override the default command to start the service in the container.
