This change creates a contrib directory in the Cinder tree and adds a project called block-box. This addition provides a method to easily create Docker images for a standalone Cinder deployment and employs a docker-compose file to enable rapid build and deployment of Cinder as a standlone service.

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`
