Vagrant
"Vagrant" is a system for managing virtual machines.
You set up a config file that sets up the vm, including installing packages and configuration settings.
Normally I run Parallels to use virtual machines on my Mac, but as of version 11, I have to pony up another $20 to get the pro version for Vagrant, and there is no current Debian provider. So I am going back to using VirtualBox for now.
Running a squid proxy
I put a proxy on Bellman so that I don't have to pull every DEB package over the Internet every time I create a new Vagrant machine.
apt-get install squid-deb-proxy squid-deb-proxy-client
On each client you can install the avahi client software and it will automatically find the server.
apt-get install squid-deb-proxy-client
The debian proxy runs on port 8000, the standard squid proxy runs on 3128 If you want to use squid as well as the dpkg cache then you need to edit /etc/squid3/squid.conf to add an acl -- acl localnet 192.168.1.0/24 for example
Using a generic Debian box
mkdir generic cd generic vagrant init debian/stretch64 vagrant up
Keeping guest additions up to date

Building a custom box

Refinement: Make the virtual hard drive smaller, there is no earthly reason for it to be 40GB. The default 8GB is big enough.
Quick version
Build a virtualbox. Use 8GB VMDK drive. Turn off audio and USB, put the network interface in bridged mode so it gets a real IP.
Install Debian into it. Name the machine 'vastra', create 2 accounts, root and vagrant. Use this as a proxy: http://192.168.1.2:8000/ Install only the ssh server and the system utilities here.
Boot the machine and set it up.
- When I need guest additions (on a development machine) I install them later. That way they are always up to date.
In Debian preseed I set up the user accounts and packages so that's done on first boot of the virtual machine. I includef openssh and sudo in the preseed file, and I set up a proxy so repeated slow Internet downloads are eliminated.
That leaves only a few things to do on first boot.
Set up keys. Log out ssh as user vagrant so you can paste this:
mkdir .ssh chmod 0700 .ssh cd .ssh wget http://bellman/vagrant.pub -O authorized_keys chmod 0600 authorized_keys chown -R vagrant ~/.ssh
su
# Allow "vagrant" to use "sudo" echo "vagrant ALL=(ALL) NOPASSWD:ALL" > /etc/sudoers.d/vagrant # Edit ssh config to allow keys. echo "AuthorizedKeysFile %h/.ssh/authorized_keys" >> /etc/ssh/sshd_config # Zero out the box dd if=/dev/zero of=/EMPTY bs=1M rm -f /EMPTY
poweroff
Package it. This turns the VM into a Vagrant Box.
cd ~/Projects/vastra-box vagrant package --base vastra-8gb mv package.box vastra-8gb.box
Add it to your inventory
vagrant box add vastra-8gb vastra-8gb.box
Test it!
vagrant init vastra-8gb cp ../vastra-ansible/Vagrantfile . # Adjust settings as needed, will this be a pbx or dev machine? emacs Vagrantfile # Deployment machines don't need this # but development machines do-- allows shared folders to work vagrant plugin install vagrant-vbguest vagrant up
This should bring the machine up and provision it to be a Vastra box all in one go.
Make a note to look at Packer to further automate this...
Vastra development machine
I need to be able to run a test machine on the Mac so that I can go offline in Gold Beach. And maybe so that I don't mess up our phones every time I get crazy testing.
cd ~/Projects mkdir vastra-debian cd vastra-debian vagrant init vastra-4gb cp ../vastra-ansible/Vagrantfile . # Select dev options emacs Vagrantfile # Allow shared src folder vagrant plugin install vagrant-vbguest vagrant up vagrant ssh
You can log into the Squid cache machine and tail its log to see that it is indeed caching package requests from the vm.
ssh bellman sudo tail -f /var/log/squid-deb-proxy/access.log
I also need to be able to simulate a target machine, one stripped down to the minimal requirements to run Vastra.
cd ~/Projects mkdir pbx cd pbx vagrant init vastra-4gb cp ../vastra-ansible/Vagrantfile . vagrant up vagrant ssh
