docker，mongorestore-错误：根目录必须是单个数据库的转储

Question

i had to update a collection on my local machine and want to upload this to a docker instance, here is my procedure

$ #backup local database
$ mongodump --collection styles --db ccc-mongo
$ tar -zcvf dump.tar.gz dump

$ scp dump.tar.gz me@remote:/home/me
$ ssh me@remote
me@remote: ~ $ docker exec -i mongo-dev sh -c "cd /tmp && tar xzf - && mongorestore --collection styles --db ccc-mongo" < dump.tar.gz

this gives me an error

connected to: 127.0.0.1
Fri Dec 18 16:05:26.768 ERROR: ERROR: root directory must be a dump of a single database
Fri Dec 18 16:05:26.768 ERROR:        when specifying a db name with --db
Import BSON files into MongoDB.

i just need to restore one collection without removing the other data, any advice much appreciated

Answer 1

this worked for me

docker exec -i mongo-dev sh -c "cd /tmp && tar xzf - && mongorestore --db ccc-mongo --drop dump/ccc-mongo  && rm -Rf dump"  < dump.tar.gz

need to make sure in the dump to just include the collection i want to restore only

Answer 2

I figured out how to do it

NOTE: please explain your question briefly. Question is not clear, please specify where you want to mondodump and restore your data - into server database or your ubuntu running computer. If into server from your local database then follow following steps:-

Here are the instructions

Copy dump folder to server

scp -r /local_path/to/dump_folder root@111.222.33.4:/remote/path

SSH into server

ssh root@111.222.33.4

Copy from root of server to inside docker container

docker cp dump_folder mongodb:/dump_folder

Go into mongodb docker container

docker exec -it mongodb bash

check if copied folder exists ls (you should see dump_folder, if you named it the same folder as in this example)

use mongorestore

mongorestore --drop -d AppName dump_folder
