# 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](https://www.packer.io/) and
|
||
[vmm(4)](https://man.openbsd.org/vmm.4) :
|
||
|
||
* This process depends on the [Go](https://golang.org/) programming language.
|
||
|
||
```
|
||
# pkg_add go packer
|
||
```
|
||
|
||
* We use the [packer-builder-vmm](https://github.com/prep/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
|
||
```

* 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*
