Cloud-Init compatible cidata iso creator

Purpose: to configure a cloud-init compatible virtual machine on a "no-cloud" setup by using a "cidata" cdrom iso file.

• Use one of the prebuilt vagrant-*.iso files to configure a instance to create a vagrant user with optional "vagrant" password.

  • This is also useful outside vagrant for any testing, because it enables a user to login the machine using a standard key/password
  • the insecure default secret key of vagrant is available under vagrant.id_rsa
  • the insecure default password of vagrant is "vagrant"

• Use your ssh publickey to create a cidata iso that configures the root user with your key.

  • Requisites for creating new iso files: bash, mkisoimage, openssl

Examples

• Create a seed iso with vagrant user and password:

  • ./create-seed-iso.sh --vagrant-password vagrant-seed.iso
  • user can login as vagrant with password vagrant or the vagrant secret key

• Create a seed iso with your id_rsa public key installed as root user and grow the root file system to the maximum available space at startup:

  • ./create-seed-iso.sh --key ~/.ssh/id_rsa.pub --growroot mykey-seed.iso
  • user can login as root with the matching ssh secret key.

• Custom Static IP Config (with vagrant user and password):

  • Warning: Static IP configurations are usually bad and break easy. (eg. change of virtual ethernet adapter will change interface name).
