容器1

宿主机

容器2

数据备份到【宿主机】

【宿主机】中备份数据再导入到【容器2】中

容器1

宿主机

容器2

导出数据（容器1）

# 1. 进入容器

docker exec -it 《容器1名称或ID》 /bin/bash

# 2. 进入数据查看需要导出的库(知道导出的数据库名可以跳过)

mongo localhost:27017

# 3. 导出数据库

# -h:主机地址 --port:端口号 -d:需要导出的数据库名称 -o:导出文件保存地址

mongodump -h 127.0.0.1 --port 27017 -d yapi -o /backup/mongodb

# 4.导出的数据库打包(tar -zcvf 《文件名》.tar.gz 《打包文件路径》)

tar -zcvf yapi.tar.gz /backup/mongdb

# 5.退出容器1

exit

数据移动【宿主机中操作】

# 1. 【容器1】中的数据库备份复制到【宿主机】/backup/mongodb

docker cp <容器1>:/backup/mongodb/yapi.tar.gz /backup/mongodb

# 2.【宿主机】/backup/mongodb 中数据库备份移到【容器2】/backup/mongodb

docker cp /backup/mongodb/yapi.tar.gz <容器2>:/backup/mongodb

导入数据（容器2）

# 1. 进入容器2

docker exec -it <容器2名称或ID> /bin/bash

# 2.解压到当前目录

tar -zxvf /backup/mongodb/yapi.tar.gz

# 3.导入到数据库

# 数据库账号【yapi】 & 密码【yapi】，避免导入失败

mongorestore -h 127.0.0.1 -u yapi -p=yapi -d 《导入的数据库名》 《导入的数据库位置》/yapi
