无聊，自建轮子
创建mongo镜像,dockerfile如下
from centos:7 RUN yum install net-tools vim -y RUN mkdir -p /mongodb/bin && mkdir -p /mongodb/conf && mkdir -p /mongodb/log && touch /mongodb/log/mongodb.log && mkdir -p /mongodb/data && chmod 755 /mongodb -R ENV MONGOD_HOME /mongodb ENV PATH $MONGOD_HOME/bin:$PATH COPY ./mongodb/bin/ /mongodb/bin/ COPY mongod.conf /mongodb/conf/mongod.conf COPY run.sh /mongodb/bin/run.sh RUN chmod a+x /mongodb/bin/run.sh CMD ["/mongodb/bin/run.sh"]
run.sh如下
#!/bin/bash
echo "######启动程序##########"
mongod -f /mongodb/conf/mongod.conf
echo "######查看端口##########"
netstat -ntulp
echo "######查看进程##########"
ps -ef |grep -v grep |grep mongod
while true
do
sleep 1h
done
mongod.conf如下

mongodb为官网下载，版本为4.2
链接 https://www.mongodb.com/download-center/enterprise
具体配置参考配置文件。
创建复制集群
登陆数据库，配置mongodb复制
shell> mongo --port 27017
config = {_id: ‘my_repl‘, members: [
{_id: 0, host: ‘172.19.0.71:27017‘},
{_id: 1, host: ‘172.19.0.72:27017‘},
{_id: 2, host: ‘172.19.0.73:27017‘}]
}
初始化这个配置
> rs.initiate(config)
查看状态,数据库已变为 PRIMARY或者SECONDARY（下面标红部分）,rs.status可查看具体配置信息

Enable MongoDB‘s free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).
The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.
To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()
