Introduction

Dockerfile to create a Docker container image for MongoDB.

MongoDB is a cross-platform document-oriented database. Classified as a NoSQL database, MongoDB eschews the traditional table-based relational database structure in favor of JSON-like documents with dynamic schemas, making the integration of data in certain types of applications easier and faster

Contributing

If you find this image useful here's how you can help:

• Send a pull request with your awesome features and bug fixes
• Help users resolve their issues.
• Support the development of this image with a donation

Issues

Before reporting your issue please try updating Docker to the latest version and check if it resolves the issue. Refer to the Docker installation guide for instructions.

SELinux users should try disabling SELinux using the command setenforce 0 to see if it resolves the issue.

If the above recommendations do not help then report your issue along with the following information:

• Output of the docker version and docker info commands
• The docker run command or docker-compose.yml used to start the image. Mask out the sensitive bits.
• Please state if you are using Boot2Docker, VirtualBox, etc.

Getting started

Installation

This image is available as a trusted build on the Docker hub and is the recommended method of installation.

docker pull sameersbn/mongodb:latest

Alternatively you can build the image yourself.

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

Quickstart

Start MongoDB using:

docker run --name mongodb -d --restart=always \
  --publish 27017:27017 \
  --volume /srv/docker/mongodb:/var/lib/mongodb \
  sameersbn/mongodb:latest

Alternatively, you can use the sample docker-compose.yml file to start the container using Docker Compose

Command-line arguments

You can customize the launch command of the MongoDB server by specifying arguments to mongod on the docker run command. For example the following command prints the help menu of mongod command:

docker run --name mongodb -it --rm \
  --publish 27017:27017 \
  --volume /srv/docker/mongodb:/var/lib/mongodb \
  sameersbn/mongodb:latest --help

Persistence

For MongoDB to preserve its state across container shutdown and startup you should mount a volume at /var/lib/mongodb.

The Quickstart command already mounts a volume for persistence.

SELinux users should update the security context of the host mountpoint so that it plays nicely with Docker:

mkdir -p /srv/docker/mongodb
chcon -Rt svirt_sandbox_file_t /srv/docker/mongodb

Logs

To access the MongoDB logs, located at /var/log/mongodb, you can use docker exec. For example, if you want to tail the logs:

docker exec -it mongodb tail -f /var/log/mongodb/mongod.log

Maintenance

Upgrading

To upgrade to newer releases:

1. Download the updated Docker image:

docker pull sameersbn/mongodb:latest

2. Stop the currently running image:

docker stop mongodb

3. Remove the stopped container

docker rm -v mongodb

4. Start the updated image

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

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 by starting bash using docker exec:

docker exec -it mongodb bash
