Deploy VM's with Terraform in 10min

OpenBSD

Managing VM’s on Hetzner Cloud with Terraform

you may want to manage some vm in the cloud. webgui is nice, but a real nerd needs cli ;)

some notes how to get terraform running with OpenBSD.

add Packages (3min)

$ time doas pkg_add git gmake go terraform

3m18.62s real     0m19.53s user     0m07.73s system

set GO PATH

echo "GOPATH=$HOME/go" >> ~/.profile
echo "export GOPATH" >> ~/.profile
. ./.profile
echo $GOPATH

build terraform provider for hcloud (2min)

As the hcloud is not available for OpenBSD, we have to build it on our own.
