Demo's for Docker

mongodb

This will build a shareded cluster, backed with two replica sets with three memebrs each

Instructions

See prov.sh

Create a machine in order to do the work from

docker-machine create -d virtualbox --virtualbox-boot2docker-url https://github.com/tianon/boot2docker/releases/download/v1.7.0-rc1/boot2docker.iso dev2
eval "$(docker-machine env dev2)"

Generate the Swarm token

docker run --rm swarm create 
483461990bff729ff6d7e57316a5ad10

sid=483461990bff729ff6d7e57316a5ad10

Start the Swarm master

docker-machine create -d virtualbox --virtualbox-boot2docker-url https://github.com/tianon/boot2docker/releases/download/v1.7.0-rc4/boot2docker.iso --swarm-image "swarm:0.3.0-rc2" --swarm --swarm-master --swarm-discovery token://$sid mongodb-swarm

Start the other docker hosts that represent the cluster

eval "$(docker-machine env --swarm mongodb-swarm)"

docker-machine create -d virtualbox --virtualbox-boot2docker-url https://github.com/tianon/boot2docker/releases/download/v1.7.0-rc4/boot2docker.iso --swarm-image "swarm:0.3.0-rc2" --swarm --swarm-discovery token://$sid mongodb-server1

docker-machine create -d virtualbox --virtualbox-boot2docker-url https://github.com/tianon/boot2docker/releases/download/v1.7.0-rc4/boot2docker.iso --swarm-image "swarm:0.3.0-rc2" --swarm --swarm-discovery token://$sid mongodb-server2 

docker-machine create -d virtualbox --virtualbox-boot2docker-url https://github.com/tianon/boot2docker/releases/download/v1.7.0-rc4/boot2docker.iso --swarm-image "swarm:0.3.0-rc2" --swarm --swarm-discovery token://$sid mongodb-server3

Start all the containers that represent the memebrs of the relica sets and the config servers

• rs1 - memebers s1rs1a, s1rs1b, s1rs1c
• rs2 - memebers s2rs2a, s2rs2a, s2rs2a
• confi1, config2, config3

docker-compose -f mdb.yaml up

See the containers

docker ps

Run the pythion script to build the ReplicaSet config and initaite the sets

python mdb.py

Run the generated yaml file to start the mongos (switch process)

docker-compose -f switch.yaml up

Copy the script that will build the sharded system and insert some data

docker-machine scp app.js mongodb-swarm:/home/docker/

Finally run the mongo shell with the script

docker run -t -i -v /home/docker:/data/scripts -e "affinity:com.docker.examples.mongodb.mongos==true" --name app alvinr/mongo 192.168.99.111:32017 /data/scripts/app.js
