Docker-Zero-to-Hero
Repo to learn Docker with examples
Docker-Zero-to-Hero is a teaching repository focused on learning Docker via explanations and concrete examples rather than just a dry reference. It starts by explaining what containers are in plain language, then compares containers vs virtual machines in terms of resource utilization, portability, security, and management. The README and supporting markdown files (commands.md, networking.md, volumes.md) walk through core Docker concepts like images, containers, networking, and persistent storage. Examples in the examples folder give you hands-on workloads to run so you can see how Docker behaves in real scenarios.

SRE Checklist
A checklist of anyone practicing Site Reliability Engineering
SRE Checklist is a practical, operations-focused checklist for running reliable services the way Site Reliability Engineering recommends. It breaks SRE good practices into concrete items: SLIs/SLOs, alerting, runbooks, on-call processes, capacity planning, backups, security, and incident response.

This makes it especially helpful for organizations that are new to SRE and want to operationalize reliability without inventing everything from scratch. The checklist format also makes audits and maturity assessments straightforward: you can see at a glance what’s in place and what’s missing. ... -
