I hope these are quick answers.
I am installing Zenoss Core 5 on CentOS7 and I am new to how Zenoss works with Docker.
- The Zenoss Control Center is nice from an administrative perspective. Is there documentation that indicates how non-admin users should access the Zenoss Core 5 dashboard How should Zenoss and the hosts files be configured if DNS is not configured for the master host.
- Can we ssh login to the Zenoss docker container
- As updates to the zenoss container are modified, what is the process of saving the container image.
Documentation and any insight will help.
Thank you,
Ken

I figured out the how to access Zenoss console via the web.. DNS or the local hosts file needs to be updated to allow web forwarding to the appropriate zenoss docker service.
I still need help with ssh login access into the container and docker container image saves.

Do you really need ssh :-)
You can use attach serviced feature, e.g.:
serviced service attach rabbitmq

I had been reading through the documentation official documentation. Trying to move from a Linux based install mindset to a docker solution with Zenoss just takes some getting use to the new architecture which by the way I like.
I found reference to using serviced in the documentation but it would be good to provide a few more examples. Your example may work for what I need.
The documentation also makes reference to creating backups / snapshots which will be quite useful for my needs.
Thanks for the assist.

Docker is such a huge shift, but what it does is awesomeness. I acquired an awesome slide deck from SCaLE 13x, and uploaded it for a community member, you may also find it to be of use. http://wiki.zenoss.org/download/core/drich_slides/DockerSlides.pdf

Cron and Custom Scripts
With Core 4, I set up cron jobs to run which would run discoveries and utilize API (REST) or ZenDMD python scripts to gather data or enrich devices. What is the recommended way to manage this with Core 5
Remote Collector
I have a new VM built. I updated the /etc/default/serviced configuration files to point to the Master Zenoss server. The /etc/hosts file was updated. I was not sure what needed to be done in the Control Console to deploy Zenoss to the remote collector. In addition, I created a new resource pool with a host and now I encounter a failure when I try to remove the new host and the resource pool.
Advice is appreciated.
Thank you,
Ken

Remote collectors have always been community supported. As of 3/12/15 the Remote Collector ZenPack has not been updated for 5.0. It's possible that someone will need to take over this effort.

| Subject: | Zenoss Core 5 Deployment Resource Pool Considerations |
| Author: | Ken Jenkins |

Per the install documentation, I believe this is what I need to build an additional Zenoss collector on our network. Can someone provide me with the what Zenoss Core 5 collector services and "how to" that needs to be deployed for a new collections resource pool I have not found any documentation on regarding which lists the Zenoss services to deploy for a resource pool colllector thus far. I also need to confirm where metrics are stored (I assume on the master host and not on the resource host). Please provide any info you have.
... From the documentation ...
Resource pools other than the default pool are known as distributed resource pools. You may create any number of distributed resource pools, and assign specific services to them. A common choice is to create distributed resource pools in different subnets or security zones, in order to deploy Zenoss Core collector instances closer to the monitored devices on the subnets. Currently, the procedures for creating distributed resource pools are identical to the procedures for creating any other resource pool.
To assign a service to a specific host, create a separate resource pool, add only the desired host to the pool, and then assign the service to the separate pool.
Zenoss Core collector services are stateless, so their storage requirements are very lightweight, compared to stateful services like MariaDB.
Thank you,
Ken
