#cloud-config variables

I’m not sure if I’m doing this the correct way.

I want to use cloud-init to configure my template’s…
my problem is that I can’t use variables in USER_DATA, I want to set hostname but the variable is empty.

CONTEXT=[HOSTNAME="$NAME",NETWORK=“YES”,USER_DATA="#cloud-config
bootcmd:

  • ifdown -a
    hostname: $HOSTNAME
    fqdn: $HOSTNAME.se-ix.delta.prod
    manage_etc_hosts: true
    packages:
  • a
  • b
  • c
    users:
  • name: foobar
    sudo: ALL=(ALL) NOPASSWD:ALL
    …
    …
    …

HOSTNAME has to be defined in the template at first level, you can use a
user input (template creation form) to let the user set it:

NAME="myfqdn"
...
CONTEXT = [ HOSTNAME="$NAME" ...

thanks, seems to work! !
another related issue I guess, is that I’m trying to create a default user…

and it dont like my passwd line, which is generated with ‘printf installer | mkpasswd --method=SHA-512 --rounds=4096’

eg:
[USER_DATA="#cloud-config
…
…
…
users:

  • name: installer
    sudo: ALL=(ALL) NOPASSWD:ALL
    passwd: $6$rounds=4096$JSIZNYut$nYB/3TXqSK8u7lSiEvmW7ate2Zbu5hIhT3tAKxS/3jqwylX2Olzl4uh2qDzaEdJ9.7z8EvB3cgBMicVE1Xn6y.

it works if I move the hash to a user input variable…

PW=“M|text|password hash” ]

and use
passwd: ‘$PW’
