Deis clusters can be provisioned anywhere CoreOS can, including on your own hardware.
Deis runs on CoreOS version 494.5.0 or later in the Stable channel.
Please refer to System Requirements for resource considerations when choosing a machine size to run Deis.
deisctl utility communicates with remote machines over an SSH tunnel.
If you don’t already have an SSH key, the following command will generate
a new keypair named “deis”:
$ ssh-keygen -q -t rsa -f ~/.ssh/deis -N '' -C deis
A discovery URL links etcd instances together by storing their peer
addresses and metadata under a unique identifier. Run this command from the root
of the repository to generate a
contrib/coreos/user-data file with a new
$ make discovery-url
Required scripts are supplied in this
user-data file, so do not provision a
Deis cluster without running
Add the public key part for the SSH key generated in the first step to the user-data file:
ssh_authorized_keys: - ssh-rsa AAAAB3... deis
CoreOS on bare metal doesn’t detect the
$private_ipv4 reliably. Replace all occurences in
the user-data with the (private) IP address of the node.
Due to changes introduced in Docker 1.3.1 related to insecure Docker registries, the hosts running
Deis must be able to communicate via a private network in one of the RFC 1918 or RFC 6598 private
Since CoreOS doesn’t detect private and public IP adresses,
/etc/environment file doesn’t
get written on boot. Add it to the write_files section of the user-data file:
- path: /etc/environment permissions: 0644 content: | COREOS_PUBLIC_IPV4=<your public ip> COREOS_PRIVATE_IPV4=<your private ip>
Assuming you have booted your bare metal server into CoreOS, you can now perform the installation to disk.
Save the user-data file to your bare metal machine. The example assumes you transferred the config
coreos-install -C stable -c /tmp/config -d /dev/sda
This will install the latest CoreOS stable release to disk. The Deis provision scripts for other
platforms typically specify a CoreOS version - currently,
647.2.0. To specify a CoreOS
version, append the
-V parameter to the install command, e.g.
After the installation has finished, reboot your server. Once your machine is back up, you should be able to log in as the core user using the deis ssh key.
See Configure DNS for more information on properly setting up your DNS records with Deis.
Now that you’ve finished provisioning a cluster, please refer to Install the Deis Platform to start installing the platform.
If your hostname after installation to disk is
localhost, set the hostname in user-data before
The hostname must not be the fully qualified domain name!
Certain DNS servers and firewalls have problems with glibc sending out requests for IPv4 and IPv6
addresses in parallel. The solution is to set the option
/etc/resolv.conf. This can best be accomplished in the user-data when installing CoreOS to
disk. Add the following block to the
- path: /etc/resolv.conf permissions: 0644 content: | nameserver 188.8.131.52 nameserver 184.108.40.206 domain your.domain.name options single-request
