CloudBoot

CloudBoot is a simple and easy-to-use installation system provided by Yunqi Technology, which is similar to Cobbler, but it is more powerful and easier to use. (see the link in Resources for details.)

RancherOS

RancherOS is an open source container operating system of Rancher Labs. Similar to coreOS,RancherOS, it is a compact and dedicated container operating system designed by Rancher Labs. It can be installed on the local hard disk of the server, deployed to the public cloud, or used with DockerMachine. Unlike Ubuntu and CentOS, RancherOS uses cloud-config.yml configuration files to manage machine configuration information, including services at system startup, network-related configuration information, storage configuration, container configuration, and so on.

Install cloudboot

See CloudBoot one-click deployment:

Http://idcos.github.io/osinstall-doc/environment/%E4%B8%80%E9%94%AE%E9%83%A8%E7%BD%B2.html

Mount the RancherOS image

Wget-P / tmp/ http://releases.rancher.com/os/latest/rancheros.isomkdir-p $PWD/cloudboot/deploy/iso/rancheros/1.5.1/mount-o loop / tmp/rancheros.iso / mediarsync-a / media/ $PWD/cloudboot/deploy/iso/rancheros/1.5.1/umount / media

Create a soft connection

Docker exec-it cloudboot / bin/shln-s / data/iso/rancheros / home/www/rancheros

Note:

CloudBoot default username password is admin/admin

Dhcp needs to be configured after login ([system Management]-> [system Settings])

Need to configure IP address range ([Network Segment Management]-> [apply Network Segment])

This article is about VMware, so there is no need to configure OOB

Device location needs to be configured ([template Management]-> [location Management])

If both CloudBoot and RancherOS are installed in the VMware virtual machine, you need to remove the dhcp from the network settings of VMware, otherwise it will conflict.

Pxe install RancherOS

Refer to RancherOS#docs#iPXE and CloudBoot PXE template customization specifications

Replace the docker mirror with the actual accelerator, if you don't need it, delete it, and replace the ssh_authorized_keys with the real ssh key.
