Initialize data on dockerized mongo

Question

I\'m running a dockerized mongo container.

I\'d like to create a mongo image with some initialized data.

Any ideas?

I've found a way that is somehow easier for me.

Say you have a database in a docker container on your server, and you want to back it up, here’s what you could do.

What might differ from your setup to mine is the name of your mongo docker container [mongodb] (default when using elastic_spence). So make sure you start your container first with --name mongodb to match the following steps:

$ docker run \
 --rm \
 --link mongodb:mongo \
 -v /root:/backup \
 mongo \
 bash -c ‘mongodump --out /backup --host $MONGO_PORT_27017_TCP_ADDR’

And to restore the database from a dump.

$ docker run \
 --rm \
 --link mongodb:mongo \
 -v /root:/backup \
 mongo \
 bash -c ‘mongorestore /backup --host $MONGO_PORT_27017_TCP_ADDR’

If you need to download the dump from to your server you can use scp:

$ scp -r root@IP:/root/backup ./backup

Or upload it:

$ scp -r ./backup root@IP:/root/backup
