Saw someone say Docker is dying โ€” not sure I agree. Truth is, Docker still plays a major role in how businesses containerize workloads. Whether you're using Podman, Kubernetes, or Docker Swarm, the right tool depends on your specific needs and context. ๐Ÿคท๐Ÿฟโ€โ™‚๏ธ Yes, Kubernetes

The moment I realized I finally "got" DevOps? When I stopped thinking in tools and started thinking in systems. It wasnโ€™t about Terraform, Ansible, or Jenkins. It was about: โ€“ Reducing manual toil โ€“ Building reliable infra โ€“ Empowering Devs โ€“ Automating trust Thatโ€™s when it
