Ansible includes a module to manage FreeBSD packages, if you’re using the forthcoming pkgng packaging system. The Ansible module isn’t complete yet, but as Ansible is moving really quickly, I’m pretty confident their FreeBSD support will grow additional knobs. As pkgng is increasingly close to production, and the PC-BSD folks have generously offered their 64-bit pkgng repository available to the public, this seems like a good time to make the move.
But I’m not about to make this change manually. Bootstrapping pkgng isn’t difficult, but I have a great big heap of FreeBSD VMs and I have other things I’d like to accomplish this month. Therefore, I’m bootstrapping my ability to manage FreeBSD packages via Ansible, with Ansible.
Before starting, you need an Ansible server and a pkgng repo.
All of my FreeBSD servers run 9.1, updated via freebsd-update. If you come across this article years later, adjust accordingly.
You also need a pkgng repository. The official repository is in closed testing, but many FreeBSD developers are using it successfully. PC-BSD has made their 64-bit repository available to all FreeBSD users. And many people have built their own repository. Thanks to my awesome Twitter
stalkers minions followers, I have access to more than one private repository. This example assumes you’re using the 64-bit-only PC-BSD repository.
Configure the pkgng repo in pkg.site. I keep my FreeBSD configuration files in /home/ansible/freebsd/etc/, so I make a /home/ansible/freebsd/etc/pkg.site that contains only:
I also need the current PC-BSD public key, saved as pkg-pubkey.cert
With these two files and an Ansible install, we’re ready to deploy on the Ansible group freebsd-test. Here’s the runbook.
--- - hosts: freebsd-test user: ansible sudo: yes tasks: - name: install pkg tools action: command pkg_add -r pkg #do you need a proxy? Put it here # environment: # ftp_proxy: http://proxy.michaelwlucas.com:8080 - name: edit /etc/make.conf action: shell echo "WITH_PKGNG=YES" >> /etc/make.conf - name: convert package database action: shell pkg2ng #I have typed pkg_add for 18 years, and my fingers no longer listen to #my brain. Disable pkg_* commands for safety - name: disable pkg_ commands action: shell chmod -x /usr/sbin/pkg_* - name: install pkg.conf action: copy src=/home/ansible/freebsd/etc/pkg.conf dest=/usr/local/etc/pkg.conf owner=root group=wheel mode=0644 #skip this if you're using a non-PCBSD repo - name: install pc-bsd pgp key action: copy src=/home/ansible/freebsd/etc/pkg-pubkey.cert dest=/usr/local/etc/pkg-pubkey.cert owner=root group=wheel mode=0644 #ansible pkg does not have upgrade command yet #use shell to trigger upgrade #pkgng package in pkg-old is always out of date, upgrade it - name: upgrade pkg pkg action: command pkg upgrade -qy #do you need a proxy? Put it here # environment: # ftp_proxy: http://proxy.michaelwlucas.com:8080
This takes a while to run.
Before deploying, test. Test again. And run your conversion in batches, so that you don’t scramble several hundred virtual machines simultaneously. Because that would really suck. Fortunately, by changing the group at the top of the playbook or specifying a new inventory file, you can batch these changes easily.Stalk me on social media
