DigitalOcean added the ability to use CoreOS
DigitalOcean announced the possibility of using the pre-installed CoreOS image the day before yesterday.
According to DigitalOcean, their integration with the alpha version of CoreOS will provide mobile and web developers interested in using Docker with an easy and fast way to launch applications and experiment with containers. In CoreOS, docker containers can start in milliseconds, providing unprecedented flexibility in managing the load on a cluster of droplets. Additional features include automatic updates, automatic network configuration and integration with etcd .
At the same time, DigitaOcean has released a number of articles on launching and configuring CoreOS :

- An Introduction to CoreOS System Components
- How To Set Up A CoreOS Cluster on DigitalOcean
- How to Create and Run a CoreOS Cluster Service
For those unfamiliar with CoreOS, I’ll say that CoreOS is a Linux distribution that is specifically designed to provide Docker- based container infrastructure with the ability to cluster multiple machines and migrate between nodes. Etcd and fleetctl are used to make the cluster work.
For those who are interested in CoreOS, here are a few links:
I have already tried to deploy the image and encountered some problems.
After that, on the initiative of the support service, a ticket was formed.

Hello,
Due to the nature of CoreOS, it doesn’t work with root passwords. Therefore, the password reset function does not work. We have been canceled the event.
If you’re having an SSH key, you can’t get it.
We would like to review the three part guide on CoreOS, available here: www.digitalocean.com/community/tutorials/an-introduction-to-coreos-system-components
Let us know if you have any questions.

It turns out that CoreOS does not need to use root access and they will soon disable the ability to reset the root-password for CoreOS-based droplets. It is necessary to use access by key, and specify “core” as the user.
