Docked MongoDB helpers

README.md

Some scripts for working with Boot2Docker and the Docker mongodb image (https://registry.hub.docker.com/u/dockerfile/mongodb/)

The scripts

mongo-cli.sh opens an interactive mongo shell

mongo-restore.sh will fetch a zip, unpack it and mongorestore a contained dump

prompt.sh will open an interactive shell in the running docker instance

start-mongod.sh will start a docker instance. When running for the first time, the image will be pulled, unless you already have it.

stop-mongod.sh will stop a running docker instance and clean up

remove-mongod.sh will remove the mongodb docker image completely

env.sh does some environment checks and setup

env.sh

# Make sure boot2docker is installed
if [ "x$(which boot2docker)" = "x" ];
then
    echo "Can't find boot2docker"
    exit 1
fi

# Make sure boot2docker is running
if [ "$(boot2docker status)" != "running" ];
then
    echo "Looks like boot2docker isn't running"
    exit 1
fi

# Check and set the DOCKER_HOST environment variable
if [ "x$DOCKER_HOST" = "x" ];
then
    $(boot2docker shellinit)
fi

# Paranoia check
if [ "x$DOCKER_HOST" = "x" ];
then
    echo "Unable to find or set DOCKER_HOST enviroment variable. Set manually and rerun"
    exit 1
fi

require_mongodb () {
    ID=$(docker ps -a | grep mongodb | grep -v "Exit" | awk '{print $1}')

    if [ "x$ID" = "x" ];
    then
        echo "Looks like mongodb isn't running"
        exit 1
    fi
}
