More #OpsEmpathy In Software Development

After years of doing DevOps now I’m in situation where there are several operation teams to work with.

System administrator job is hard. They have to make sure everything works smooth all the time. That includes the complex legacy system that nobody fully understands. Such work is often invisible and goes unappreciated.

Do The Dirty Work Yourself First

Such experience led me to the insight: have more empathy for people who maintain your software. It does not matter if you have separate operation team or doing DevOps. The person taking care of your app will be grateful. Also keep in mind that person could be future you. The future you who did not slept well and has got huge hangover (been there, done that).

The success of your software is on the shoulders of giants!

Try Docker To Make Yourself Uncomfortable

Using Docker you are able to simulate cluster on your laptop with all the warts and shortcomings of production environment: no easy access to files, limited way to peek how application is performing (trace, debug), network access restrictions from one container to another. The default Docker configuration is pretty restrictive — just how any reasonable system administrator would do it.

Put Yourself In The Shoes Of The Maintainer

Rise-up and leave the comfort of IDE and try to pin down the root cause of a bug using toolset available for admins. Instead of interactive debugger try to process application logs with grep and awk. That might be quite a challenge, which means logs need improvement. Bear in mind: setting log level to DEBUG is cheating!
