Change Hostname and IP Address on Hypriot

hypriot.md

Change hostname on hypriot

Option 1: Do it after the SD card has been imaged and loaded on first boot

Change hostname by editing each of these files:

/etc/hosts
/etc/hostname
/etc/cloud/cloud.cfg 

Change IP Address:

vi /etc/network.d/50-cloud-init.cfg

Change IP by editing that file. Still to work out how to change username and password. raspi-config does not work.

Example of 50-cloud-init.cfg:

auto eth0
iface eth0 inet static
address <>/<>
gateway <>
domain_name_servers=1.1.1.1, 9.9.9.9

Option 2: Flash the drive with the appropriate userdata parameters

Flash drive using the flash utility with the following parameters:

flash --userdata /home/ricdeez/tmp/user-data hypriotos-rpi-v1.12.3.img

Copy of user-data file:

#cloud-config
# vim: syntax=yaml
#

# Set your hostname here, the manage_etc_hosts will update the hosts file entries as well
hostname: slave-XX
manage_etc_hosts: true

resize_rootfs: true
growpart:
  mode: auto
  devices: ["/"]
  ignore_growroot_disabled: false
# You could modify this for your own user information
users:
  - name: pirate
    gecos: "Hypriot Pirate"
    sudo: ALL=(ALL) NOPASSWD:ALL
    shell: /bin/bash
    groups: users,docker,video,input
    plain_text_passwd: xxxxxx
    ssh-authorized-keys:
      - ssh-rsa key 1
    lock_passwd: false
    ssh_pwauth: true
    chpasswd: { expire: false }
