Docker iscsi in container run cmd

docker-iscsi

# This will use the hosts iscsid 
docker run -it --net=host  --privileged -v /etc/localtime:/etc/localtime:ro \
    -v /lib/modules:/lib/modules:ro \
    -v /run:/run:shared -v /dev:/dev \
    -v /etc/iscsi:/etc/iscsi \
    -v /home/jgriffith/vol:/Mount:shared ubuntu bash
    
# shared declaration on Mount matters!

# You can also put iscsid in another container, share the socket
# BUT make sure you do NOT run the iscsid on the host node

Hey John,

Would this allow me to define unique iSCSI initiatornames per docker container or am I still tied to docker host's iqn?
Yes, it does. I wasn't doing my RTFM.

I made a wee change in the bind mappings from
-v /etc/iscsi:/etc/iscsi to -v /root/iscsi1:/etc/iscsi in an attempt to not touch the host iscsi config. I copied iscsid.conf from /etc/iscsi to /root/iscsi1
I could run iscsid in the container with my own iqn. Now, to see if I can run multiple!
Cheers.

Is it possible to run iscsid in a k8s' pod's container? What flags do I need to pass in that case (assuming that the container runs in privileged mode)?

@princerachit, I have success with that:

Nice, thanks for adding that @kvaps ! I'm afraid I never noticed the comments on this gist
