Debian Nursery

Nursery for automatic deployment of Debian systems

Concept :

  • PXE Boot
  • Retrieving a minimal preseed file (debian installer)
  • Local application of a puppet manifest corresponding to the desired target

Targets available:

  • Install Debian Bullseye manual (amd64)
  • Install Debian Bullseye (amd64)
  • Install Debian Bullseye deployment (amd64)
  • Install Debian Bullseye development (amd64)
  • Install Debian Bullseye kvm server (amd64)
  • Install Debian Bullseye jitsi-meet server (amd64)

Requirements

Starting the Nursery server

  • Start the box to make the PXE server operational for the private subnet nursery.

    vagrant up

Stop the Nursery server

  • Stop the box

    vagrant halt

Deploying a target on a virtual machine

  • Start the server

  • Create a blank virtual machine with the desired characteristics.

  • On the virtual machine, connect the first network interface on the private subnet nursery.

  • Booting the virtual machine via PXE

  • Select the desired target in the PXE menu

Deploying a target on a real machine

  • On the server, disable the second network interface of the private subnet nursery.

  • On the server, add a new network interface via USB<->ETH adapter for example.

  • Start the server

  • On the real machine, connect the first network interface to the private subnet nursery via the USB adapter.

  • Booting the real machine via PXE

  • Select the desired target in the PXE menu

Miscellaneous

  • Destroy the box and associated resources

    vagrant destroy

  • Connect to the box via ssh

    vagrant ssh

  • To keep the /vagrant and /var/www/html directories synchronized for testing, run the following command in a shell host:

    vagrant rsync-auto

Converting a vdi disk to qcow2 for deployment on a kvm infrastructure

qemu-img convert -f vdi disk.vdi -O qcow2 disk.qcow2

Optional. For those who like to work with chains - Start server with NTLM corporate proxy

  • Add a .profile file in the user's directory to configure the web proxy

    Proxy Settings

    export ALL_PROXY=http://NtlmCorporateProxy:3128 export http_proxy=$ALL_PROXY export https_proxy=$ALL_PROXY

  • Install the Vagrant vagrant-proxyconf plugin

    vagrant plugin install vagrant-proxyconf

  • Modify the Vagranfile.ntlm file to position the web proxy. NtlmCorporateProxy

  • Replace the Vagrantfile with Vagrantfile.ntlm.pp

  • Replace the MyDomain account in the puppet recipe file deployment-server.ntlm.pp. cf. MyAccount to configure the web proxy

  • Replace deployment-server.pp with deployment-server.ntlm.pp

  • Start the box

    vagrant up

  • Connect to the box via ssh

    vagrant ssh

    • To keep the /vagrant and /var/www/html directories synchronized, run the following command in a shell host:

      vagrant rsync-auto

  • In the box run the command "sudo cntlm -H" in order to generate the hash for the web proxy cntlm

  • Copy the generated hashes into the puppet recipe file deployment-server.pp. cf. MyHash

  • Re-execute the puppet recipe to take into account these changes

    sudo puppet apply /vagrant/deployment-server.pp

  • Resume the web proxy for apt to use the same NtlmCorporateProxy (todo...)

    /etc/apt/apt.conf.d/01proxy Acquire::http::Proxy "http://localhost:3128/"; Acquire::https::Proxy "https://localhost:3128/";

  • Exit the box with the "logout" command

  • Stop the box

    vagrant halt

  • Disable the proxy in the Vagrantfile so as not to cascade web proxies

    if Vagrant.has_plugin?("vagrant-proxyconf") config.proxy.http = "http://NtlmCorporateProxy.MyDomain:3128/" config.proxy.https = "https://NtlmCorporateProxy.MyDomain:3128/" config.proxy.no_proxy = "localhost,127.0.0.1,.MyDomain" end

  • restart the box

    vagrant up

  • The PXE server should finally be operational on the private network nursery!!! If not, please contact the "Specialists" of your IS ;-)
