1. Trim images: Multi-stage builds, alpine/minimal bases, fewer layers.
2. Tag with intent: Semantic tags and immutable digests; avoid latest in prod.
3. Harden defaults: Least-privilege containers, read-only filesystems, no root when possible.
4. Use compose: Model multi-service installs with docker-compose and env files.
5. Integrate with package managers: Automate installs/updates via apt, dnf, or brew where appropriate.
6. Improve diagnostics: Log drivers, healthchecks, and clear error output during setup.
7. Automate post-install: Seed configs, networks, volumes with idempotent scripts.

Smaller, safer, faster. That trio never steers you wrong.

6. Kubernetes

Kubernetes orchestrates containers across clusters—deploys, scales, heals, and rolls them forward (or back) when needed.

Why It's Important

Complex apps become manageable. Installers can encode desired state, ship Helm charts, and deliver consistent outcomes across environments.

How to Improve Kubernetes Skills

1. Start simple: Spin up clusters with kubeadm or a managed service, then tear down and repeat.
2. Automate provisioning: Use Terraform or Ansible to stamp out reproducible clusters.
3. Package apps: Learn Helm; template values, secrets, and lifecycle hooks.
4. Secure by default: RBAC, namespaces, network policies, image scanning.
5. Observe everything: Metrics with Prometheus, logs with Fluentd/Fluent Bit, and dashboards for quick triage.

Treat clusters as cattle, not pets. Recreate confidently.
