The name "ursa" is derived from a Latin word that means "bear".

Feature

• manage bare-metal server
  • save to sqlite
• headless boot server using iPXE
  • include a some servers (dhcpd, httpd, tftpd)
• provisioning cloud-init nocloud-net in bare-metal
  • create linux users
  • insert user authorized keys
  • bonding network interface by ursa-bonder

Getting Started

prepare a some binaries and put to ./cmd/ursa/static .

• initrd.img
• kernel
• filesystem.squashfs

Build

Please use Makefile.

$ make

Put binaries and files to Server

static directory is DocuemntRoot in HTTP Server.

$ tree .
.
├── static
│   ├── filesystem.squashfs
│   ├── initrd.img

Execute ursa!

$ sudo ./ursa -iface eth0 -dhcp-range "192.0.2.100:192.0.2.200" -service-nw "198.51.100.0/24" -service-gw "198.51.100.1" -service-range "198.51.100.100:198.51.100.200"
# Listen 67/udp (DHCP), 69/udp (TFTP), 80/tcp (HTTP), so need root permission.

Next, you boot bare-metal server in same Layer2 Network.

It becomes...

• boot OS from initrd.img using iPXE.
• set IP address to bonding interface from one of -service-range.
• set IP address to management interface from one of dhcp-range.
