Installation

Pull the latest version of the image from the docker index. This is the recommended method of installation as it is easier to update image in the future. These builds are performed by the Docker Trusted Build service.

docker pull sameersbn/mongodb:latest

Alternately you can build the image yourself.

git clone https://github.com/sameersbn/docker-mongodb.git
cd docker-mongodb
docker build -t="$USER/mongodb" .

Quick Start

Run the mongodb image

docker run -name mongodb -d sameersbn/mongodb:latest

To test if the mongodb server is configured properly, try connecting to the server.

mongo $(docker inspect --format {{.NetworkSettings.IPAddress}} mongodb)

Data Store

You should mount a volume at /var/lib/mongodb.

mkdir -p /opt/mongodb
docker run -name mongodb -d \
  -v /opt/mongodb:/var/lib/mongodb sameersbn/mongodb:latest

This will make sure that the data stored in the database is not lost when the image is stopped and started again.

Shell Access

For debugging and maintenance purposes you may want access the containers shell. If you are using docker version 1.3.0 or higher you can access a running containers shell using docker exec command.

docker exec -it mongodb bash

If you are using an older version of docker, you can use the nsenter linux tool (part of the util-linux package) to access the container shell.

Some linux distros (e.g. ubuntu) use older versions of the util-linux which do not include the nsenter tool. To get around this @jpetazzo has created a nice docker image that allows you to install the nsenter utility and a helper script named docker-enter on these distros.

To install nsenter execute the following command on your host,

docker run --rm -v /usr/local/bin:/target jpetazzo/nsenter

Now you can access the container shell using the command

sudo docker-enter mongodb

For more information refer https://github.com/jpetazzo/nsenter

Upgrading

To upgrade to newer releases, simply follow this 3 step upgrade procedure.

• Step 1: Stop the currently running image

docker stop mongodb

• Step 2: Update the docker image.

docker pull sameersbn/mongodb:latest

• Step 3: Start the image

docker run -name mongodb -d [OPTIONS] sameersbn/mongodb:latest
