Just 22 lessons across 6 courses covering:</p> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code>Docker Basics (images, containers, volumes, networks) Docker Compose (multi-service setups, healthchecks, hot reload) SSH Tunnels &amp; Docker (remote containers, Docker context) Production Tips (multi-stage builds, security, cleanup) Docker Swarm (services, stacks, secrets) Monitoring &amp; Logging (logging drivers, cAdvisor, Prometheus) </code></pre> </div> <p>The idea was: can you learn enough Docker in a weekend to be productive? Turns out yes — if you cut the filler.</p> <p>It's built with SvelteKit + Postgres, dark mode by default (obviously), self-hosted Plausible for analytics (no GA), and fully bilingual (EN/DE).</p> <p>Would love feedback from anyone who gives it a spin. What's missing? What's over-explained? What's under-explained?</p> <p>→ <a href="https://dockhand.lol" rel="noopener noreferrer">https://dockhand.lol</a></p> docker devops beginners webdev
