##Mongo DB To run mongo as a single db that can be linked to the container running the server, use this command:
$ docker run -d --name db0 -p 27017:27017 mongo:latest --smallfiles --noprealloc
Make sure that you start out by creating the folders on the host that we want the mongo db to map to. You can create them by running the following commands in your home dir
$ mkdir mongodata
$ cd mongodata
$ mkdir -p rs0-0 rs0-1 rs0-2
Start a docker container with mongo and connect to it interactivily so it won't start the mongod service by default
$ docker run --name rs -ti -v ~/mongodata:/data/db mongo bash
Run 3 mongo instances on different ports (eg. 27017, ..18, ..19) by execuring the following commands:
$ mongod --port 27017 --fork --logpath=/root/rs0.log --dbpath /data/db/rs0-0 --replSet rs0 --smallfiles --oplogSize 128
$ mongod --port 27018 --fork --logpath=/root/rs1.log --dbpath /data/db/rs0-1 --replSet rs0 --smallfiles --oplogSize 128
$ mongod --port 27019 --fork --logpath=/root/rs2.log --dbpath /data/db/rs0-2 --replSet rs0 --smallfiles --oplogSize 128
All mongod instances is now running in a service on the same machine but on different ports. Now, log into the first machine to configure it
$ mongo --port 27017
Save the following command as a variable rsconf in the mongo shell.
> rsconf = { _id: "rs0", members: [ { _id: 0, host: "localhost:27017" }, { _id: 1, host: "localhost:27018" }, { _id: 2, host: "localhost:27019" } ] }
OBS: Be sure to replace localhost with the correct ip of you container.
Next up, run the following command in the mongo shell to initiate to replica set
> rs.initiate( rsconf )
> rs.conf()
The first command initiates the replica set with your configuration variable (containing the configuration BSON object).
Now run a new docker container and link it to the mongo container created earlier.
$ docker run -d --name daemon --link rs:rs -p 37123:37123 lundtoft/skycave:latest bash /root/cave/start-mongo.sh
You should now have a SkyCave server connected to a mongo replica set.
