Why intro for sec and ops people
- I've worked as sysadmin, devops/security person since 2013
- I've been using Go (together with some Bash and Perl/Python) since 2018
- mostly small/medium sized one/two-person programs
Why sec and ops people should program
- to better understand how software works
- to better understand dev people
- to create tools, automation, PoCs
Why Go
- focus on simplicity, reliability (correctness) and speed
- lot of cloud is written in Go (e.g. Kubernetes, terraform)
- nice addition to Bash and/or Python since it's quite different
Go peculiarities
- packages, types, goroutines, channels:
cd fetch - cross-compilation to a single binary:
GOOS=linux GOARCH=arm64 go build fetch.go - methods and interfaces:
cd shop - small and secure images:
docker build -t shop . && docker run -p 8000:8000 shop
