You'll need to modify how you're doing things to get to the iscsi Target. Specifically, using a Docker network hoses everything because the IP of the target is the internal containers IP NOT the IP of the host.
Setting network_mode: host solves this.. but that creates a new problem.
Can't use link when using network_mode: host.
Sigh... so; docker run has "add-host=host:IP" that we should be able to find equivalent in compose. We just need to define a network and assign IP's to the other containers, then this should work.
Compose looks like this: extra_hosts: - "hostname:1.1.1.1" - "anotherhost:2.2.2.2"
This just adds entries to /etc/hosts for you. Kinda handy
So, if we create a network and assign IP's to the supporting cast (rabbit,
mariadb api etc etc) we can then just use this to make them accessible instead
of using link
OHHHH! Add ipc_mode: host, shared memory; may speed things up a bit?
Finally... for reference; The docker run command for this looks something
like:
docker run -it \ -v /dev/:/dev/ \ -v /run/:/run/:shared -v /etc/localtime:/etc/localtime:ro \ --net host \ --privileged cinder_debian \ bash
vim /etc/lvm/lvm.conf # disable udev_ stuff /usr/sbin/tgtd tgtadm --lld iscsi --op show --mode target tgtadm --lld iscsi --op new --mode target --tid 1 -T iqn.2001-04.com.example:storage.disk2.amiens.sys1.xyz tgtadm --lld iscsi --mode logicalunit --op new --tid 1 --lun 1 -b /dev/vg-group/lv tgtadm --lld iscsi --op bind --mode target --tid 1 -I ALL
