This playbook makes digital rebar provision servers

Pre work

• Put a ssh public key in secrets/pubkey.for.drpuser
• This should be a key your ansible user is configured to try

Requirements on your drp servers

• Not much: a bare-bones install and the root password
• preferrably a machine nobody has logged into
• Tested against 'minimal' install of RHEL7.

Adding your first drp server(s)

0. ssh to nosuchuser@ to save the host key, then ctrl-c
1. add the hostname to the drpservers section in hosts
2. for each host added, run the 'firstrun' tag (use the root password)

 $ ansible-playbook t firstrun -e "ansible_ssh_user=root" -k site.yml -l <hostname>

3. run the whole playbook on everybody

 $ ansible-playbook site.yml

What do I need to change?

1. Your network definitions. And decide how you are going to run this ...

• once they're built, depend on this to be running and have the uuid in complete state so it doesn't boot to sledgehammer?
• create a task in the complete stage to turn off pxeboot ... or at least have pxe after disk (only if disk is not bootable)
• build subnets out completely and remove dhcp helper that points here?
• something else? or combination of above?

2. Your own OS images, integrated with kickstarts and pushing into your post-buildout workflows ...

3. more fancy ipmi tasks and stages

4. why not do something useful instead of sledgehammer-wait if you've got the machines powered on?

Sorta faq

adding more drpservers, now or later

GOTO step 0

updating drpservers, checking configuration

Do step 3

I need something to do often, like daily or hourly

Step 3 sounds good

Why can't I log in to the drpserver anymore? I have the root password!

No, seriously ... let me back in! I need to do my job now that the automation ran!

start making roles in a new branch, and do step #3 ...

what about testing stuff

1. Make some vms (on your kvm host)

$ for i in $(seq 1 9); do ./testarmy.sh ; done

2. Wait a bit until they boot and register - then start building (on your drp server)

$ sleep 180 && dodrp list
$ dodrp buildall

3. There is no step three. But if you want to clean stuff up:

On your host:

$ for i in $(seq 1 10); do sudo virsh destroy bootmonkey${i} ; done
$ for i in $(seq 1 10); do sudo virsh undefine bootmonkey${i} ; done
$ for i in $(seq 1 10); do sudo rm -f /storage/bootmonkey${i}.qcow2 ; done

And on your drp server:

$ dodrp deleteall
