Mongrel is a MongoDB docker image created for building containers running internal mysql servers with docker using the Alpine image as the base. The dockerfile is written in a format to be base dockerfile for another project. It does not execute mysql on start but lays the foundation for you to have a quick start for one.

The dockerfile creates a binary file bootmgo in /bin/ which starts mysql with relation to provided parameters.

Included with the docker file is a db.js in Conf, which will be added into the image built in data/db/mongodb/, this can be used after running the mongodb within the image to setup basic user rights and permissions.

To build just run the following:

make build

To push just run the following after ensuring docker credentials for docker repository is set:

make push

To run the docker image built using the docker file:

• To run as a non-deamon:

docker run -it ${image_name} bootmgo

• To run as a deamon:

docker run -it ${image_name} bootmgo --fork

See configuration file for customization in Conf

The parameters below help define and indicate areas which can be set at lunch of mysql binary to provide user wanted values for the server.

• MongoDB Port (Default: 27017)

  • Environment Variable: MONGODB_PORT

• AUTH Flag

  • Environment Variable: $AUTH This flag when giving any value will cause the bootmgo command after running mongod to execute the /data/db/mongodb/db.js file using mongo

The database when started would attempt to store all data files within /mnt/db/mongodb, which allows you to customly mount the underline filesystem of the server where the container of this image would be executed to ensure files are stored within the host and not the container.
