1.) cAdvisor - https://github.com/jangaraj/serviced-app-cadvisor
I would like to use cAdvisor with serviced. I need to "reproduce" docker command:
docker run \
--volume=/:/rootfs:ro \
--volume=/var/run:/var/run:rw \
--volume=/sys:/sys:ro \
--volume=/var/lib/docker/:/var/lib/docker:ro \
--publish=8080:8080 \
--detach=true \
--name=cadvisor \
google/cadvisor:latest

But container is not starting:
[root@dev ~]# serviced service start cAdvisor
Service already started
[root@dev ~]# serviced service stop cAdvisor
Scheduled 1 service(s) to stop
[root@dev ~]# serviced service start cAdvisor
Scheduled 1 service(s) to start
[root@dev ~]# serviced service status cAdvisor

Logstash: no log for "cadvisor". Volumes exist on the host. Docker container is starting OK, but when I use serviced, then it's not starting.

Maybe config of serviced:
# Set the loglevel for serviced
# SERVICED_LOG_LEVEL=0 - I've tried also SERVICED_LOG_LEVEL=5, but no useful details in the log
# Set the port on which to listen for profiler connections (-1 to disable)
# SERVICED_DEBUG_PORT=6006

2.) skyline app - https://github.com/jangaraj/zenoss5-skyline
I would like to use linked containers with serviced:
docker run --name redis3 -d redis
docker run -d -p 1500:1500 -P --link redis3:redis klynch/skyline python ./skyline.py -r redis://redis:6379/ settings -i data/settings.json && python ./skyline.py -r redis://redis:6379/ horizon -u 2025 & && python ./skyline.py -r redis://redis:6379/ analyzer &

How can I expose (link) redis port 6379 from redis container to skyline container only I don't want to expose it to the host.
How can I achieve that redis container will be started before skyline container

Hi -

At this time, we don't currently support mounting arbitrary host filesystem locations into containers. This is a feature that is in the backlog for a later release.

The design of serviced utilizes an NFS-shared directory that is the context for any 'Volume' declarations in your service definitions. For example, if you define a volume as

{ "Owner": "root:root", "Permission": "", "ResourcePath": "the-rootfs-vol", "ContainerPath": "/rootfs", "Type": "" }

then that service will have a volume mounted at '/rootfs' that maps to /opt/serviced/volumes//the-rootfs-vol on the master host. This is, at a minimum, part of your problem.

For additional logging, you can do 'serviced service logs ' which will print out stdout/stderr of the process. If a container is starting and then immediately stopping, you can look in logstash in the Control Center UI for logs form the container.

OK, I can't run cadvisor with serviced at the moment.
