I’ve had entirely too much fun with Ansible this weekend. Looking forward to drastically improving how I manage my servers!
After a few successful months of testing Packet.net, I've once again moved
git.ethitter.com. The decision was purely financial–my GitLab instance doesn't receive enough traffic to warrant Packet.net's pricing. As far as reliability and value were concerned, Packet.net was excellent. I would've appreciated built-in backups, but otherwise, I have no complaints about the service.
It will likely come as little surprise that git.ethitter.com is back on Linode. Compared to Digital Ocean, Linode is slightly more-generous with its resources, and GitLab wants all the resources it can get.
The migration itself was quite easy, with most of the time was spent preparing the server; GitLab's backup/restore process did most of the hard work. Now I just have to finish the ancillary setup, like monitoring.
Almost exactly four years after I first installed GitLab, I’ve migrated my instance to a new host, and in the process, finally switched to their “omnibus” install.
With 40 domains–plus a half dozen certificates–to track, I added the DomainMOD tool to my repertoire. Its API integrations, in particular, made it an appealing choice, as I had little desire to manually enter so many details. After three months, I’m quite pleased with my decision.
Installation was as straightforward as a git checkout, creation of a MySQL table, and the addition of a server block to my nginx configuration. With DomainMOD successfully running, I configured it to use my mailserver, then got to importing my domains.
After Mozilla’s devastating report, and both Chrome and Firefox’s decision to stop trusting StartSSL certificates issued after October 28, I had no choice but to replace the certificates I’d obtained through StartSSL.
The process took a few months, mainly due to the associated costs. While most of my StartSSL certificates were replaced with ones issued by Let’s Encrypt, there were a few cases where LE wasn’t appropriate. This primarily impacted domains that have many, many subdomains, however there were also a few cases where Let’s Encrypt’s three-month duration would’ve been burdensome. Ultimately I had to purchase three wildcard certificates, plus three single-domain certificates. With those installed, I’m now free of StartSSL/Wosign. After sixty days, I can rotate the pinned keys, impeding any further use of my legacy StartSSL certificates.
To anyone who follows my posts here, my love of open-source software is well-known. Open-source alternatives allow me to host my own nameservers, email, website, and GitHub alternative, and I’ve now supplanted Slack and automation tools like IFTTT and Zapier.
I’ve been using PHP 7.0 for just over a year, and the 7.1 branch reached its first stable release last month, so I’ve begun thinking about what the switch will entail. Fortunately, my needs are fairly simple, so I only require two additional modules: Redis and GeoIP. I’ve made one hasty attempt to build 7.1 with support for these features, which failed spectacularly; fortunately, the chance that it was an error on my part is quite good, so things may just work when I try it again.
Sadly, I’m not yet able to drop PHP 5.6 support from my VPS as a few necessary applications still don’t work as expected under newer releases.
KeyCDN is rather spectacular. I’ve used them for more than two years now, and their features-for-price are unmatched. Of greatest importance to me, they support custom SSL certificates as part of their basic offering. Given my obsession with HSTS and HPKP (see also), this was essential.
In the last six months, they’ve spared my VPS appreciable traffic:
I can’t recommend KeyCDN enough. I’m told that Brotli and IPv6 support are coming in the first quarter of 2017. 🎉
Last year, Google released a successor to the
deflate compression algorithm, Brotli. Chrome adopted it in version 51, and Firefox in version 44 (see Can I use…). That said, from the webserver side, nginx doesn’t support it natively, so Google provides the
ngx_brotli module, making it just a matter of compiling nginx.
