EvoBSD 1.0

EvoBSD is an ansible project used for customising OpenBSD hosts used by Evolix.

How to install an OpenBSD machine

Note : The system must be installed with a root account only. Put your public key in the remote root's autorized_keys (/root/.ssh/authorized_keys)

1 - Install ansible's prerequisites

ansible-playbook prerequisite.yml -CDi hosts -l HOSTNAME

2 - Run it

ansible-playbook evolixisation.yml --ask-vault-pass -CDKi hosts -l HOSTNAME

Testing

Changes can be tested by using Packer and vmm(4) :

• This process depends on the Go programming language.

# pkg_add go packer

• We use the packer-builder-vmm project to bridge Packer and vmm(4)

$ go get -u github.com/prep/packer-builder-vmm/cmd/packer-builder-vmm

• Here is an example build file

$ vim openbsd.json

{
  "description": "OpenBSD installation on vmm(4)",

    "hostname":    "evobsd",
    "domain":      "example.com",

        "install -af install.conf<enter>",
        "<wait2m>",

        "/sbin/halt -p<enter><wait15>"
      ]
    }
  ]
}

• You need your unprivileged user to be able to run vmctl(8) through doas(1)

# echo "permit nopass myunprivilegeduser as root cmd /usr/sbin/vmctl" >> /etc/doas.conf

• Build the virtual machine

$ packer build openbsd.json

• Start it

doas vmctl start evobsd -cL -d output-vmm/evobsd.qcow2

• Enable NAT on your host machine

pass out on em0 inet from tap0:network to any nat-to (em0)

assuming em0 is your egress interface
