## What A full revamp of the `/guides` section — taxonomy, structure, and UX. Preview: https://deploy-preview-25338--docsdocker.netlify.app/guides/ ### Taxonomy & structure - Replaces the sprawling 24-tag set with a focused 9-tag taxonomy aligned to use case / SDLC: **Languages & frameworks, AI, Testing, CI/CD, Security, Databases, Deployment, Admin, Hands-on labs**. - Removes the languages taxonomy entirely (`data/languages.yaml` and all `languages:` front matter). - Collapses all multi-page guide series into single pages, with aliases so old sub-page URLs continue to resolve. - Deletes redirect-only shim pages and flattens directory-wrapped single pages. ### Landing page (`/guides/`) - A clean index: hero, then category sections listing each guide as a plain **title / summary** row. - **Browse rail** (sticky, left): click a topic to filter the page to just that topic's guides; "All guides" resets. A count + Clear bar appears while filtering. - **Text filter**: instant client-side search over title, summary, and tags. Topic filter and text search are mutually exclusive and share the same flat-list view. - No more "Featured guides" section. ### Guide content pages - Removes the left sidebar for the guides section (mobile drawer kept). - Centered reading column (`92ch`) with the TOC taking the remaining width. - Summary rendered as a lead paragraph under the h1. - TOC scrollbar auto-hides until hover; breadcrumbs render at a consistent size inside and outside `prose`. ## Notes - Deep full-text search across guide bodies is still handled by the existing site-wide Pagefind (⌘K); the landing filter is the fast metadata-narrowing surface. - `series.html` is retained — it's still used by `get-started` pages. ## Validation - Site builds clean locally (Hugo dev server, no errors / broken refs). - All collapsed sub-page URLs redirect via aliases. ## Follow-ups - Prune guides that we no longer need/want - Tighten the guides that span too many concepts (e.g. language guides; remove cicd/deploy/sscs) 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>

| Lab: Docker Compose Quickstart | Lab: Docker Compose Quickstart | Build a multi-container Flask and Redis application from scratch using Docker Compose. Learn health checks, watch mode, named volumes, and multi-file configurations. | Hands-on lab: Define and run a multi-container app with Docker Compose. Progress from a bare compose.yaml through health checks, live development with watch mode, data persistence, and modular Compose file composition. | Docker, Compose, multi-container, Flask, Redis, watch mode, volumes, lab, labspace |
|
Build a Python Flask and Redis hit-counter app using Docker Compose, starting
from a bare compose.yaml and progressively adding production-quality
features at each step.
Launch the lab
{{< labspace-launch image="dockersamples/labspace-compose-quickstart" >}}
What you'll learn
By the end of this Labspace, you will have completed the following:
- Define a multi-service application in a
compose.yamlfile and manage it with Compose commands - Control service startup order using health checks and
depends_onconditions - Iterate on code without manual rebuilds using Compose watch mode
- Persist data across container restarts with named volumes
- Modularize a stack across multiple files using the
includedirective - Use
config,logs, andexecto inspect and debug a running stack
Modules
| # | Module | Description |
|---|---|---|
| 1 | Introduction | Tour the starter app and verify the environment |
| 2 | Defining Services | Write the first compose.yaml and bring up the Flask and Redis stack |
| 3 | Health Checks & Startup Order | Add a Redis healthcheck and depends_on to eliminate race conditions |
| 4 | Live Development with Watch Mode | Configure watch mode to sync code changes without manual rebuilds |
| 5 | Persistence & Debugging | Add a named volume so Redis data survives docker compose down |
| 6 | Using Multiple Compose Files | Extract Redis into infra.yaml and compose files with include |
| 7 | Additional Commands | Use config, logs -f, and exec to inspect the running stack |
| 8 | Recap | Review what was built and explore next steps |
