OS Setup a VM from scratch (VirtualBox, with packer and vagrant)

Creation of virtualbox images is done via packer.

This setup relies on packer being able to accept incoming connections, so review firewall on the host if it's not working. It also requires the variables["mirror"] setting in the packer json file correspond to the HTTP server in the http/install.conf.

As this setup uses OpenBSD autoinstall, it's necessary to set DHCP variables:

option tftp-server-name "openbsd-mirror.soyuz.local:8080";
option bootfile-name "auto_install";

(the type-server-name corresponds, again, to the variables["mirror"] setting in the packer json file. The dhcp options (for VMWare Fusion) are set in /Library/Preferences/VMware Fusion/vmnet8/dhcpd.conf (then restart the process to apply changes. Probably /Applications/VMware Fusion.app/Contents/Library/vmnet-dhcpd -s 6 -cf /Library/Preferences/VMware Fusion/vmnet8/dhcpd.conf -lf /var/db/vmware/vmnet-dhcpd-vmnet8.leases -pf /var/run/vmnet-dhcpd-vmnet8.pid vmnet8)

Setup or review the file (the varfile) containing the private packer variables (ssh_private_key_file, ssh_public_key_str, root_bcrypt_hash)
cd ~/Code/setup-scripts/packer
packer build -var-file=<path-to-varfile> openbsd.json
The ovf and vmdk files will be found in the output_directory specified in the openbsd.json file. Take note of the path to the ovf file that's been created, as it is necessary below.
vagrant box add --name openbsd64 build/openbsd64-amd64-vmware.box
cd into a directory under vagrant, that defines the type of machine that you want, and look at the config.vm.box. Vagrant won't pull in the machine that you've just built if it's already been important. If vagrant box list shows a box with the same name as the config.box.vm directive in the Vagrantfile then run vagrant box delete <name-of-box>
run vagrant up
If you haven't done a DHCP mapping, find the new IP address on the DHCP server (look for recent DHCPACK log line in /var/log/daemon if it's OpenBSD)
Login as root, using the private key associated with the ssh_private_key_file that was used in the packer setup phase

OS Setup a Vultr cloud host from scratch

OpenBSD requires hand-installation on Vultr, even though they offer pre-build images because their partitioning scheme only has a single partition.

boot from ISO that has installation packages e.g. install70.iso
do an auto-install, using an auto-install conf. Note that noVNC (used by Vultr) has a paste option in the client's pop-out, so you don't need to type in the autoinstall URL - https://raw.githubusercontent.com/edwinsteele/setup-scripts/master/autoinstall/gemini-install.conf
detach the ISO (which triggers a reboot on Vultr - manual reboot may be necessary)

Provisioning using ansible once the OS setup is complete

Once the base OS has been setup, we do further setup using ansible. Assumes that your default ssh public key is installed on the server under the account that you'll be using for provisioning (root), or that you provide a different key to ansible with --private-key=PRIVATE_KEY_FILE

General pre-work

workon ansible (the virtualenv should already exist from previous work)
cd ~/Code/setup-scripts/ansible
Replace the host in hosts with the IP address of the newly provisioned host, placing it in the group section that corresponds to the --limit argument used in the ansible-playbook commands for the appropriate type of VM install e.g. ansible-playbook -u root -i inventory site.yml --limit=192.168.20.254

Performing non-OS setup

Note that it's not possible to test ansible connectivity on OpenBSD hosts until they have a python interpreter, which is the first step in the common playbook.

In the ansible directory at the same level as this README.md file run:

ansible-playbook -u root -i hosts --limit <limit-criteria> site.yml

Where the limit criteria is something like:

192.168.56.101 (an IP address)
webservers (a single group name)
'webservers:&192.168.56.101' (the union of a group and an IP address)

Additional steps

On the newly provisioned VM as root (in an ssh session with agent forwarding enabled):
openrsync -av www.wordspeak.org:/etc/ssl/wordspeak.org/ /etc/ssl/wordspeak.org/
openrsync -av www.wordspeak.org:/etc/ssl/private/wordspeak.org/ /etc/ssl/private/wordspeak.org/
rcctl restart nginx
On the newly provisioned VM as esteele (in an ssh session with agent forwarding enabled):
for d in images.wordspeak.org language-explorer.wordspeak.org staging.wordspeak.org www.wordspeak.org; do openrsync -av www.wordspeak.org:/home/esteele/Sites/$d/ /home/esteele/Sites/$d/; done
cd ~/Code/dotfiles && ./make.sh flip the DNS to point to the new host
doas acme-client -v wordspeak.org && rcctl restart nginx

For Webserver

Update DNS record for staging.wordspeak.org (to simplify final setup, knowing that nobody is looking at staging)
rsync -av --rsync-path=/usr/bin/openrsync /usr/local/var/www/lex-mirror/ staging.wordspeak.org:/var/www/htdocs/language-explorer.wordspeak.org/
in images.wordspeak.org checkout, run ./images_tool.py sync
