Findings on CoreOS
Hi All,
Here are my findings on CoreOS, past couple of days.
- No package manager: CoreOS doesn't have a package manager, and expect
users to use containers (such as Docker) in order to do any real work.
- It's consisted of Kernel + Containers
- It inherently supports HA clusters based on a VM discovery mechanism.
- CoreOS updates get applied automatically.
- Supports both Docker and nspawn (even light weight than Docker)
containers.
- Uses Systemd
- System management daemon
- Services, timers and one-off jobs
- Logging support through Journal.
- Uses etcd
- A key-value database
- provides service discovery for cluster
- similar to consul & zookeeper
- Uses Fleet (similar to Mesos)
- For cluster level service management
- Schedules jobs across nodes in a cluster
- Reschedules units of failure
- Can initialize from a cloud-config file
- Uses a discovery endpoint to find out the members of a cluster (we can
plug our own discovery service).
Also, I was successfully able to spin up a CoreOS cluster in EC2. Further,
I will work on CoreOS-Stratos integration.

Yes, sure Lakmal. I'll post what ever the questions we have to Core OS
mailing list.
Thanks Chris for coordinating with Polvi!

Re: Findings on CoreOS
Posted by chris snow <ch...@gmail.com>.
Hi guys,
I've been in contact with CoreOS and have had a really positive response
from Alex Polvi. He has suggested to use the CoreOS user mailing list, but
we can reach them directly if required.
Should we nominate one person to coordinate sending our stratos-coreos
integration questions to the CoreOS user list so they don't get hit by
multiple independent questions?
Many thanks,
Chris

Further, I feel even Fleet and Stratos has some common interests such as ;
* starting docker containers
* service grouping.
* providing HA etc.

Hi Nirmal, it sounds like we should be collaborating with the coreos team?
I expect they will have strong views on the direction we go?

I think that'll be the case. But need to experiment and see.

Will stratos just manage coreos and not have to care which container
manager, fleet or kubernetes is used by coreos?
