Mongodump and mongorestore with Docker

Story

If you want to backup, export and migrate the MongoDB schema, you can use MongoDB Tools or command-line

And today i will presentation about command-line utilities mongorestore and mongodump with Docker.

A. Export data with mongodump

1. Create mongodb container with Docker

- (create without authentication)
docker run -d --name mongodb -p 27017:27017 mongo:latest

- (create secure with username/password)
docker run -d --name mongodb -p 27017:27017 -u username -p password mongo:latest

- (create with existing data)
docker run -d --name mongodb -p 27017:27017 -v $PATH_OF_MONGODB_VOLUME/data:/data/db mongo:latest

You can find PATH_OF_MONGODB_VOLUME with command "docker inspect" and you will see the "Mounts" section in the output.

2. Exec to the mongodb container (bash)

docker exec -it mongodb bash

3. To export the data, use command "mongodump" and the output path name "dump_backup"

mongodump -o dump_backup

- (secure with username/password)
mongodump -u username -p password -o dump_backup

So, the dump_backup file have been created. But the output file (dump_backup) is created inside the container's filesystem. So you need need to copy it from the container to your host (local).

4. Copy dump_backup file from container to local.

docker cp $CONTAINER_NAME:/$BACKUP_FILE_NAME/$DATABASE_NAME PATH_TO_LOCAL

docker cp mongodb:/dump_backup/blogs /Desktop/backup/dump_backup_local

Now. In the local, access to path ../Desktop/backup/dump_backup, you will see the binary files of a database

B. Import data with mongorestore

1. Copy file from local to the docker container

docker cp /Desktop/backup/dump_backup_local mongodb:/dump_backup

2. Exec to container and import the dump_backup file to the mongodb

mongorestore -u $USERNAME -p $PASSWORD --authenticationDatabase=admin -d $DATABASE_NAME $BACKUP_FILE_NAME

mongorestore -u username -p password --authenticationDatabase=admin -d blogs /dump_backup (if with secure username/password)

mongorestore -d blogs /dump_backup (if without secure username/password)

Finally

If the database just deploy production. You only ssh to the host and do the same. I hope you find the information here useful
