As me & my wife are bootstrapping our own start-up, there are many things we have to do by our own. One of them is devops, which I’m currently still have many things to learn. A friend of mine introduced me to Docker half a year ago and I find the idea is quite interesting. I decided to give it a try and tried to setup a Dockerized OrientDB on Google Compute Engine (GCE).
I setup a GCE instance using an instruction from Google Documentation on Container. Then I use OrientDB image from Joao P Dubas. I managed to run the container but I didn’t know how to get the OrientDB root password 😕
When you run OrientDB for the first time, it will generate a root user with long & random password in its config file. I need to access the config file inside the container but I didn’t know how.
I started to Google around and found a Stack Overflow post on how to run shell or do SSH into a running container. I found a very interesting post about NOT to do SSH into container but use Docker volume instead. I decided to try to use volume.
So I checked the Dockerfile and it seems that OrientDB runs on folder
/opt/downloads/. I just need to make that folder accessible as a Docker volume. To make sure, I also check the log output by doing
sudo docker logs orientdb on my GCE instance. The OrientDB config file is located at
After removing the old OrientdDB container, I re-run the OrientDB container with command:
sudo docker run -d --name orientdb -p 2424:2424 -p 2480:2480 -v /opt/downloads joaodubas/orientdb:latest
That will make the folder
/opt/downloads a Docker volume. Now I just have to run another container which can access the same volume. I ran a simple container with shell:
sudo docker run --volumes-from orientdb -i -t busybox /bin/sh
BOOM! Now I could access
/opt/downloads/orientdb/config/, read the
server-config.xml file, and search for the users sections:
<users> <user resources="*" password="3C76542178HG987LIUWLKJJKKJSH983HYT" name="root"/> <user resources="connect,server.listDatabases,server.dblist" password="guest" name="guest"/> </users>
Now I can run OrientDB console on my local machine and access the remote server with user root and password 3C76542178HG987LIUWLKJJKKJSH983HYT.
