Mongodb Manual

Backup the db

# run docker exec

docker exec -it mongo_server /bin/bash

# mongodump -h 127.0.0.1 --port 27017 -u [user] -p [pass] -d [dbname] -o /backup/dump --authenticationDatabase admin
# tar -zcvf testDB.tar.gz /backup/dump/testDB
# remove the dir
mongodump -u admin -p admin --authenticationDatabase admin -o /backup/dump  \
&& tar -C /backup/dump -zcvf /backup/all.tar.gz . \
&& rm -rf /backup/dump/*

Store the db

注：

1、mongorestore恢复数据默认是追加，如打算先删除后导入，可以加上--drop参数，不过添加--drop参数后，会将数据库数据清空后再导入，如果数据库备份后又新加入了数据，也会将新加的数据删除，它不像mysql有一个存在的判断。

# run docker exec

docker exec -it mongo_server /bin/bash

# unzip && restore all dbs
tar -C /backup/store -zxvf /backup/all.tar.gz \
&& mongorestore -u admin -p admin --authenticationDatabase admin --drop /backup/store/  \
&& rm -rf /backup/store/*
