SRE best practices

don’t expect a tool to solve
cultural change and need “believers” in senior role to advocate within company

“Reliability is a journey”

it is a process that can span 6-9 months in orgs w/ 5000 engineers; nothing happens immediately
Step 1: “I want to be reliable when I grow up” (you must believe you have problem first)

Configuration

For this, I placed config files into etc/letsencrypt/configs, named after <domain>.conf. The files are simple:
