MongoDB Replica set version-docker

1. Host and container planning

Docker host	Container name	Port	Replica set
192.168.0.40	M40	27017	Rs0
192.168.0.41	M41	27017	Rs0
192.168.0.42	M42	27017	Rs0

2. Create container 2.1 to create a container on host 40 M40

docker run     --name m40                                 -d                                         -p 27017:27017                             -v /etc/localtime:/etc/localtime:ro        -v /data/db:/data/db                       -v /data/configdb:/data/configdb           reg.citms.cn/public/mongo:3.2.19           mongod --replSet rs0

2.2. Create a container on host 41 M41

docker run     --name m41                                -d                                        -p 27017:27017                            -v /etc/localtime:/etc/localtime:ro       -v /data/db:/data/db                      -v /data/configdb:/data/configdb          reg.citms.cn/public/mongo:3.2.19          mongod --replSet rs0

2.3. Create a container on host 42 M42

docker run     --name m42                                -d                                        -p 27017:27017                            -v /etc/localtime:/etc/localtime:ro       -v /data/db:/data/db                      -v /data/configdb:/data/configdb          reg.citms.cn/public/mongo:3.2.19          mongod --replSet rs0

3. Build a replica set

# # #3.1. Connect one of the containers and run the MONGO shell

docker exec -it m40 mongo

# # #3.2. Initialize replica set

rs.initiate( {   _id : "rs0",   members: [      { _id: 0, host: "192.168.0.40:27017" },      { _id: 1, host: "192.168.0.41:27017" },      { _id: 2, host: "192.168.0.42:27017" }   ]})

# # #3.3. View replica set configuration, output slightly

rs.conf()

# # #3.5. Identify the primary node of the replica set, the output is slightly

rs.status()
