Initial host setup

Get initial playbook files to the VM, two options are below

Get initial playbook from local source

# clone https://github.com/aragozin/loadlab_vm.git to your desktop machine

mkdir -p /opt/loadlab/setup

# copy content of repo to /opt/loadlab/setup via sftp

cd /opt/loadlab/setup/ansible/provision.alpine
apk add ansible
ansible-playbook ansible/provision.alpine/host-setup.yml

Get initial playbook from github repo

apk add git
mkdir -p /opt/loadlab
git clone github https://github.com/aragozin/loadlab_vm.git setup

Install LXD and apply host configuration

cd /opt/loadlab/setup/
apk add ansible
ansible-playbook ansible/provision.alpine/host-setup.yml
