Pagerduty provides a built-in way to export your incident data but only a limited number of data fields are available on the basic plan. Rather than upgrade you can use the API to export the data to a CSV. I found this gist listed here. The python script works great but some of my incident messages contained JSON data that threw off Excel when opening the CSV. I slightly modified the script with character escaping to work around this (lines 98- 107). ...
I spent way too long troubleshooting a script step in a Jenkins declarative pipeline this week. After lots of frustration I stumbled upon this gist that was a life saver. Long story short you need \\ to escape literal quotes.
I’ve often found myself with an instance id that I want to login to look at something. It sucks looking up the IP when you don’t know the DNS name. I’m sure there are other ways to do this but here is what I came up with. getec2ip() { aws ec2 describe-instances --instance-ids $1 | jq [.Reservations[0].Instances[0].PrivateIpAddress] | jq --raw-output .[] } assh() { host=$(getec2ip ${1}) ssh user@${host} } This relies on the aws cli and jq to parse out the ip and has made it much easier for me to quickly hop on an instance. ...
There is a nice plugin for Jenkins that lets you dynamically add capacity by spinning up EC2 instances on demand and then terminating them when the job queue expires. This is a great way to save money on an AWS based build infrastructure. Unfortunately, the plugin documentation is really light and there are a few gotchas to look out for. Security Groups This field only accepts comma separated security group IDs, not names. This is frustrating because other fields in the plugin take a space separated list (e.g. labels) ...
Now that roles and profiles are in my control repo my RSpec tests are taking longer then ever. As of this writing the control repo contains 938 tests and I’m still a long way from 100% coverage. This really slows down the feedback loop when running tests. When running locally I often just run RSpec against a specific spec file rather then run the whole test suite, but I still wanted a way to speed things up in Bamboo. ...
I spent some time tackling technical debt in our Puppet code this week. The biggest outstanding item was implementing eyaml for protecting secrets in Hiera. I’d also been encouraging developers to contribute to the Puppet code base for some time, but they were restricted from the control repo due to some secrets kept in Hiera. This put a big damper on collaboration as Hiera is the data engine for our roles and profiles. Separate git repos were also used for the profile and role modules due to this workflow. ...
I updated our Active Directory lita plugin today with support for querying the members of a given group. See https://github.com/knuedge/lita-activedirectory. It still needs some work to properly present errors when a user or group doesn’t actually exist in the directory. Right now it returns nothing rather then a helpful error. It works splendidly with legit users and groups however. ChatOps ftw!
rnelson0 is walking through automated Puppet testing with Jenkins on his blog. I thought I’d highlight how you can use a similar workflow in Atlassian’s Bamboo application. This assumes you already have a working Bamboo setup and are familiar with the general process for testing Puppet modules with rspec. Create a new plan The first step is to set up a new plan to use for the testing. Click “Create” and then “Create a new plan” in the top menu bar. ...
Two days ago I finished our migration to Puppet 4. Overall I’d say the process was pretty painless. The gist of what I did start running rspec tests against Puppet 4 fix issues found in tests run the catalog preview tool and fix any issues found turn on the future parser on the existing master turn off stringify facts create new master and PuppeDB server migrate agents to new master Thankfully our code wasn’t too difficult to update and most of the forge modules we use had also been updated. ...
My favorite keyboard is up on Massdrop again. I highly recommend it. For the nerds keeping score I waffle between brown and blue switches(the clears made my fingers tired). https://www.massdrop.com/buy/code-keyboard-tenkeyless?referer=FNWB57
