docker-compose deploy replicaSet in standalone MongoDB cluster and with auth

After two days of agonizing, finally achieved their desired effect, it is through the docker-compose deploy the latest mongodb replicaSet, mainly to test the latest 4.2 multi-document transactions, will share with you the entire steps below:

docker-compose.yml follows:

version: '3.4'

services:
    mongo:
        container_name: mongodb
        image: mongo:latest
        hostname: mongodb
        volumes:
          - /data/mongodb/mongod.conf:/etc/mongod.conf
          - /data/mongodb/data/db/:/data/db/
          - /data/mongodb/data/log/:/var/log/mongodb/
          - /data/mongodb/initdb.d/:/docker-entrypoint-initdb.d/
        environment:
          - MONGO_INITDB_ROOT_USERNAME=root
          - MONGO_INITDB_ROOT_PASSWORD=123456
        ports:
            - "27017:27017"
        healthcheck:
            test: test $$(echo "rs.initiate().ok || rs.status().ok" | mongo -u root -p '123456' --quiet) -eq 1
            interval: 10s
            start_period: 30s
        command: ["--replSet", "rs0", "--bind_ip_all"]

　　

Description:

1, /data/mongodb/mongod.conf files need built in advance, as follows, mainly to enable verification, if you do not mount the file, replicaset in the streaking

2, scripts in /data/mongodb/initdb.d This directory is used to initialize, provided that the former does not perform any data, I created in the directory create-app-user.sh  to initialize custom database [yourdb user name] and [password] [123456] yourAdmin, reads as follows:

#!/usr/bin/env bash
echo "Creating mongo users..."

mongo admin -u root -p 123456 << EOF
db.createUser({user: 'admin', pwd: '123456', roles: [{role: 'userAdminAnyDatabase', db: 'admin'}]});
db.grantRolesToUser(
   "admin",
   [ "clusterAdmin" ]
);
EOF

mongo admin -u admin -p 123456 << EOF
use yourdb
db.createUser({user: 'yourdbAdmin', pwd: '123456', roles:[{role:'readWrite',db:'yourdb'}]})
EOF
echo "Mongo users created for yourdb."

 

3, can be used to test monog client login:

   

mongo -u root -p 123456

　After a successful login, a drop like this:

Execution  show dbs;  you can see their databases built, built himself a test user and password, you can use:

mongo -u yourdbAdmin -p 123456 --authenticationDatabase yourdb
