使用身份验证重新启动 mongodb docker

Question

I have a mongoDB docker with name hi_mongo and id 123456789 I have some data already stored in the DB. I have stopped it sometime back and restarted with the command:
docker restart 123456789

But now I want to restart this docker with authorization enabled. How to do it without making a new mongoDB docker.

What I have tried so far is - enter this mongoDB container using:
docker exec -it 123456789 /bin/bash
and tried editing the /etc/mongo.conf.orig file and setting the authorization:'enabled' thinking that when I restart the docker from host mongod will restart with auth enabled but that is not the case.

Answer 1

Would be able to enable auth by modifying the entrypoint.sh in container. Try below steps:

1) docker exec -it yourcontainer bash

2) find out the mongo configs in your run. it is probably just exec mongod. but for safety, find it out first.

sed -i 's/exec "$@"/echo "new entrypoint $@" > \/tmp\/echo.txt/g' entrypoint.sh

stop and start container again. attach to container and check /tmp/echo.txt.

3) replace exec "$@" in entrypoint.sh with like exec mongod --auth .

4) restart the container, mongod should run with auth enabled.

You should really consider to store the data in a volume instead inside the container.

Answer 2

I am using MongoDB 3.4 and It looks fine. What I did is that

• Stop your running container. ( docker stop your_container_name )
• db.createUser({"user":"admin","pwd":"password","roles":[ {role:"root",db:"admin"}]});
• Edit your mongodb config. ( in my case /etc/mongod.conf )
• Restart your container. ( docker restart your_container_name)

When you tried to create new user after login then you will get folowing an error.

db.createUser({"user":"demo","pwd":"password","roles":[ {role:"read",db:"admin"}]}); 2016-12-24T14:17:43.949+0000 E QUERY

Hope this helps you.
