Enable Mongodb auth with Docker

README.md

• Run mongodb without auth

  docker run --name mongo_db --cpus="1" -m 2G -e MONGODB_EXTRA_FLAGS='--wiredTigerCacheSizeGB=1' --restart always -v /home/$USER/.mongodata:/data/db -d mongo:3.6

• Connect to mongodb without auth and create root user

  use admin
  db.createUser({ user: "root", pwd: "root_password", roles: [ "root" ] });

• Create other user (for app database)

  use my_db_name
  db.createUser({ user: "my_db_user", pwd: "my_db_password", roles:[ { role: "readWrite", db: "my_db_name" } ] });

• Create read only user (for app database)

  use my_db_name
  db.createUser({ user: "my_db_readonly_user", pwd: "my_db_readonly_password", roles:[ { role: "read", db: "my_db_name" } ] });

• Run mongodb with auth (enable auth in mongodb with --auth flag)

  docker run --name mongo_db --cpus="1" -m 2G -e MONGODB_EXTRA_FLAGS='--wiredTigerCacheSizeGB=1' --restart always -v /home/$USER/.mongodata:/data/db -d mongo:3.6 --auth

• Connect to mongodb with auth (root admin user)

  docker exec -it mongo_db mongo -u root -p root_password

• Connect to mongodb with auth (database user)

  docker exec -it mongo_db mongo -u my_db_user -p my_db_password --authenticationDatabase my_db_name
