(including after daemon restart). + `unless-stopped` does the same **unless** the container was manually stopped; in that case it stays stopped across daemon restarts. + +2. **Docker Compose networks vs Docker bridge networks** + Compose creates and manages **project-scoped networks** (by default) and connects services by name with built-in DNS. + A plain Docker bridge network can be manually created/managed and attached to containers; Compose typically abstracts this and namespaces resources per project. + +3. **Referencing Ansible Vault variables in templates** + Yes — Vault-encrypted variables decrypt at runtime (given the vault password) and can be used like normal variables inside Jinja2 templates (be careful not to leak secrets into logs/artifacts). + +4. **`community.docker.docker_compose_v2` basics** + - `state: present` ensures the project is up (roughly “compose up”) + - `state: absent` brings it down (roughly “compose down”) + - `recreate` controls whether containers are recreated (`auto`, `always`, `never` depending on module support/version) + +--- + +## Task 3: Wipe Logic (1 pt) + +### Implementation + +- **Defaults:** `ansible/roles/web_app/defaults/main.yml` + - `web_app_wipe: false` +- **Wipe tasks:** `ansible/roles/web_app/tasks/wipe.yml` + - Tagged `web_app_wipe` + - Gated by `when: web_app_wipe | bool` +-

The tag enables a “wipe-only” mode without running deployment tasks. + +2. **Difference between `never` tag and this approach** + The `never` tag prevents execution unless explicitly tagged, but it’s easy to misread and can be overridden by tag selection. The variable+tag approach makes the wipe intent explicit in runtime configuration and supports both wipe-only and clean reinstall flows. + +3. **Why must wipe logic come BEFORE deployment?** + For clean reinstall, you need a deterministic ordering: remove old deployment first, then deploy fresh. Putting wipe first guarantees that if enabled, it runs before compose up. + +4. **Clean reinstall vs rolling update** + - Clean reinstall: when state/config drift is suspected, major configuration changes, corrupted volumes, or when you want a known-clean slate. + - Rolling update: when you want minimal downtime and preserve state/volumes while updating an image/version. + +5. **Extending to wipe images/volumes** + Add optional flags/vars that (when enabled) call `docker image rm ...` and remove named volumes/networks; keep those as additional gated steps because they’re more destructive and may impact other apps. + +--- + +## Task 4: CI/CD (3 pts) + +### Workflow added + +- **File:** `.github/workflows/ansible-deploy.yml` +- **Triggers:** Push/PR on changes under `ansible/**` +- **Jobs:** + - `lint`: installs `ansible` + `ansible-lint`, runs `ansible-lint` + - `deploy`: sets up SSH, writes vault password file, runs deployment, verifies with `curl` + +### Required GitHub Secrets + +Set these in GitHub repo Settings → Secrets and variables → Actions: + +- `ANSIBLE_VAULT_PASSWORD` +- `SSH_PRIVATE_KEY` +- `VM_HOST` +- `VM_USER` +- Optional: + - `APP_PORT` (defaults to `8000`) + - `HEALTHCHECK_PATH` (defaults to `/health`) + +### Evidence + +- Screenshot of a successful run (lint + deploy + verify) +- Logs showing `ansible-lint` passing +- Logs showing `ansible-playbook` execution +- Verify step output showing `curl` succeeds + +### Research answers (Task 4) + +1. **Security implications of storing SSH keys in GitHub Secrets** + Secrets reduce accidental exposure, but compromise of repo admin permissions or CI runner environment could leak keys. Mitigations: least-privilege keys, short-lived keys/certs, IP allowlists, rotate regularly, and restrict who can trigger deployments. + +2. **Staging → production pipeline** + Use separate environments (e.g., `staging` and `production`) with approvals for production, different inventories/vars, and gated promotion (deploy staging on push, deploy production on release/tag or manual approval). + +3. **Adding rollbacks** + Pin versions (image tags), keep previous known-good tag, and add an explicit “rollback” workflow input that redeploys the last good version. Also store release metadata and validate health before promotion. + +4. **How self-hosted runner improves security vs GitHub-hosted** + It avoids sending SSH keys to a shared runner environment and can run inside your trusted network perimeter. You can limit network egress/ingress and reduce exposure of long-lived credentials. + +--- + +## Task 5: Documentation (1 pt) + +This file (`ansible/docs/LAB06.md`) is the documentation and evidence record for Lab 6. + +--- + +## Testing Results (fill in) + +- Tag runs (`--tags`, `--skip-tags`) +- Docker Compose idempotency (2nd/3rd run mostly `ok`) +- Wipe scenarios 1–4 +- GitHub Actions workflow run +- Application reachable via `curl` + +--- + +## Challenges & Solutions (fill in) + +- What broke? +- How it was diagnosed? +- What was changed to fix it? + +--- + +## Summary + +- **Key learnings:** blocks/rescue/always, tag-driven runs, Compose templating, dependency ordering, safe wipe patterns, CD via GitHub Actions. +- **Time spent:** 6 hours diff --git a/ansible/docs/image.png b/ansible/docs/image.png new file mode 100644 index 0000000000..31a032be57 Binary files /dev/null and b/ansible/docs/image.png differ diff --git a/ansible/group_vars/all.yml b/ansible/group_vars/all.yml new file mode 100644 index 0000000000..2f7bf200c7 --- /dev/null +++ b/ansible/group_vars/all.yml @@ -0,0 +1,18 @@ +$ANSIBLE_VAULT;1.1;AES256 +32626135353732643334383863613364343133653332343963663130383661613264303035633539 +6338383862316664333831646339626661333262366564310a613830303165373238393035323531 +61303734633766316666343231313765373564313132613862316334303333636366383835326236 +3335623233616139310a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diff --git a/ansible/inventory/hosts.ini b/ansible/inventory/hosts.ini new file mode 100644 index 0000000000..35490a2bc6 --- /dev/null +++ b/ansible/inventory/hosts.ini @@ -0,0 +1,2 @@ +[webservers] +woolfer-vm ansible_host=158.160.56.244 ansible_user=ubuntu \ No newline at end of file diff --git a/ansible/playbooks/deploy.yml b/ansible/playbooks/deploy.yml new file mode 100644 index 0000000000..d7314ed404 --- /dev/null +++ b/ansible/playbooks/deploy.yml @@ -0,0 +1,10 @@ +--- +- name: Deploy application + hosts: webservers + become: true + vars_files: + -

Technical Analysis + +- **Why it works:** Uvicorn runs as `appuser`, binds to `0.0.0.0:5000` so the host can reach it when you use `-p`. Dependencies are installed in an earlier layer, so the app has FastAPI/uvicorn available. +- **Layer order:** If we copied everything first and then ran `pip install`, any change to `app.py` would invalidate the cache and re-run `pip install` every time. Putting dependencies first keeps installs cached. +- **Security:** Non-root user, minimal files in the image, no dev/test tooling. `.dockerignore` keeps `.git` and secrets out of the build context. +- **`.dockerignore`:** Reduces context sent to the daemon (faster `docker build`) and prevents `docs/`, `tests/`, `venv/`, `.git` from being considered for `COPY`, so they never end up in the image. + +## 5.

Terraform vs Pulumi Comparison + +**Ease of Learning:** Terraform's HCL is simpler for basic infra — fewer concepts and a clear declarative model. Pulumi requires knowing both the IaC concepts and a programming language, but if you already know Python it feels natural. + +**Code Readability:** Terraform is more concise for simple resources. Pulumi's Python code is more verbose due to `*Args` classes, but offers better IDE support with autocomplete and type hints. + +**Debugging:** Pulumi errors include Python stack traces which are familiar. Terraform errors reference HCL line numbers and can be cryptic for complex expressions. + +**Documentation:** Terraform has a larger community and more examples online. Pulumi docs are good but fewer community examples exist, especially for Yandex Cloud. + +**Use Case:** Terraform for straightforward infra with broad team adoption. Pulumi when you need complex logic, reuse via functions/classes, or your team already uses Python/TypeScript heavily. + +## 5.

Terraform vs Pulumi Comparison + +**Ease of Learning:** Terraform's HCL is simpler for basic infra — fewer concepts and a clear declarative model. Pulumi requires knowing both the IaC concepts and a programming language, but if you already know Python it feels natural. + +**Code Readability:** Terraform is more concise for simple resources. Pulumi's Python code is more verbose due to `*Args` classes, but offers better IDE support with autocomplete and type hints. + +**Debugging:** Pulumi errors include Python stack traces which are familiar. Terraform errors reference HCL line numbers and can be cryptic for complex expressions. + +**Documentation:** Terraform has a larger community and more examples online. Pulumi docs are good but fewer community examples exist, especially for Yandex Cloud. + +**Use Case:** Terraform for straightforward infra with broad team adoption. Pulumi when you need complex logic, reuse via functions/classes, or your team already uses Python/TypeScript heavily. + +## 5.

**Workers:** Latency-sensitive HTTP/HTTPS logic, global APIs, JWT validation, A/B at edge, small JSON services. + +**Recommendation:** Use Workers for this lab’s style of edge API; use Kubernetes when you need container-native workloads and full control over orchestration. + +### Reflection + +- **Easier than Kubernetes:** No nodes, images, or ingress to operate; deploy and URL in one command. +- **More constrained:** No arbitrary TCP servers, no traditional file system, CPU/memory/time limits per invocation. +- **Not Docker:** You ship a **Worker bundle**, not an OCI image; the platform

Hook Implementation + +Implemented hooks: +- `pre-install` Job (`templates/hooks/pre-install-job.yaml`) with weight `-5`. +- `post-install` Job (`templates/hooks/post-install-job.yaml`) with weight `5`. + +Execution order: +- Lower weight runs first, so pre-install executes before release resources. +- Post-install executes after resources are created. + +Deletion policy: +- Both hooks use `helm.sh/hook-delete-policy: hook-succeeded`. +- Successful hook Jobs are removed automatically after completion. + +## 4.

containers; readiness removes unready pods from service load balancing. `/health` returns uptime + status — sufficient to detect unhealthy state. + +**Resource limits:** Prevent a single pod from starving the node.

Security Analysis + +Kubernetes Secrets: +- Simple and native. +- Good for small setups with strong RBAC + etcd encryption. +- Weak for centralized secret governance and dynamic credentials. + +Vault: +- Centralized policies, auditing, rotation, dynamic and leased secrets. +- Better for production and multi-environment security controls. + +Recommendation: +- Use K8s Secrets only for low-risk/simple cases. +- Use Vault for production-grade secret lifecycle and access control. + +## Bonus + +Implemented: +- `vault.hashicorp.com/agent-inject-template-config` annotation in

renews/refreshes secret material and rewrites rendered files. +- Optional `vault.hashicorp.com/agent-inject-command` can trigger app reload after updates. + +RESULT: + +```bash

The same Nix expression produces **identical binaries** on any machine, forever. -**Provided Files:** -- `labs/lab18/index.html` — A beautiful course landing page ready to deploy +**Building on Your Work:** Throughout this lab, you'll revisit your DevOps Info Service from Lab 1 and compare: +- **Lab 1**: `requirements.txt` vs Nix derivations for dependency management +- **Lab 2**: Traditional `Dockerfile` vs Nix `dockerTools` for containerization +- **Lab 10** *(bonus task)*: Helm `values.yaml` version pinning vs Nix Flakes locking --- -## Exam Alternative Requirements +## Prerequisites -| Requirement | Details | -|-------------|---------| -| **Deadline** | 1 week before exam date | -| **Minimum Score** | 16/20 points | -| **Must Complete** | Both Lab 17 AND Lab 18 | -| **Total Points** | 40 pts (replaces 40 pt exam) | +- **Required:** Completed Labs 1-16 (all required course labs) +- **Key Labs Referenced:** + - Lab 1: Python DevOps Info Service (you'll rebuild with Nix) + - Lab 2: Docker containerization (you'll compare with Nix dockerTools) + - Lab 10: Helm charts (you'll compare version pinning with Nix Flakes) +- Linux, macOS, or WSL2 +- Basic understanding of package managers +- Your `app_python/` directory from Lab 1-2 available --- ## Tasks -### Task 1 — IPFS Fundamentals (3 pts) +### Task 1 — Build Reproducible Python App (Revisiting Lab 1) (6 pts) + +**Objective:** Use Nix to build your DevOps Info Service from Lab 1 and compare Nix's reproducibility guarantees with traditional `pip install -r requirements.txt`. + +**Why This Matters:** You've already built this app in Lab 1 using `requirements.txt`. Now you'll see how Nix provides **true reproducibility** that `pip` cannot guarantee - the same derivation produces bit-for-bit identical results across different machines and times. + +#### 1.1: Install Nix Package Manager + +> ⚠️ **Important Installation Requirements:** +> - Requires sudo/admin access on your machine +> - Creates `/nix` directory at system root (Linux/macOS) or `C:\nix` (Windows WSL) +> - Modifies shell configuration files (`~/.bashrc`, `~/.zshrc`, etc.) +> - Installation size: ~500MB-1GB for base system +> - **Cannot be installed in home directory only** +> - Uninstallation requires manual cleanup (see [official guide](https://nixos.org/manual/nix/stable/installation/uninstall.html)) + +1. **Install Nix using the Determinate Systems installer (recommended):** + + ```bash + curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install + ``` + + > **Why Determinate Nix?** It enables flakes by default and provides better defaults for modern Nix usage. + +
+ 🐧 Alternative: Official Nix installer + + ```bash + sh <(curl -L https://nixos.org/nix/install) --daemon + ``` + + Then enable flakes by adding to `~/.config/nix/nix.conf`: + ``` + experimental-features = nix-command flakes + ``` + +
+ +2. **Verify Installation:** + + ```bash + nix --version + ``` + + You should see Nix 2.x or higher. + + **Restart your terminal** after installation to load Nix into your PATH. + +3. **Test Basic Nix Usage:** + + ```bash + # Try running a program without installing it + nix run nixpkgs#hello + ``` + + This downloads and runs `hello` without installing it permanently. + +#### 1.2: Prepare Your Python Application + +1. **Copy your Lab 1 app to the lab18 directory:** + + ```bash + mkdir -p labs/lab18/app_python + cp -r app_python/* labs/lab18/app_python/ + cd labs/lab18/app_python + ``` + + You should have: + - `app.py` - Your DevOps Info Service + - `requirements.txt` - Your Python dependencies (Flask/FastAPI) + +2. **Review your traditional workflow (Lab 1):** + + Recall how you built this in Lab 1: + ```bash + python -m venv venv + source venv/bin/activate + pip install -r requirements.txt + python app.py + ``` + + **Problems with this approach:** + - Different Python versions on different machines + - `pip install` without hashes can pull different package versions + - Virtual environment is not portable + - No guarantee of reproducibility over time + +#### 1.3: Write a Nix Derivation for Your Python App + +1. **Create a Nix derivation:** + + Create `default.nix` in `labs/lab18/app_python/`: + +

Deployed on IPFS via 4EVERLAND

- - +🔧 Python app doesn't run: "command not found" or "No such file or directory" + +**Problem:** Your `app.py` doesn't have a shebang line and isn't being wrapped with Python interpreter. + +**Solution:** Ensure you're using `makeWrapper` in your `default.nix`: + +```nix +nativeBuildInputs = [ pkgs.makeWrapper ]; + +installPhase = '' + mkdir -p $out/bin + cp app.py $out/bin/devops-info-service + + wrapProgram $out/bin/devops-info-service \ + --prefix PYTHONPATH : "$PYTHONPATH" +''; ``` -**Access URLs:** -- 4EVERLAND: `https://your-project.4everland.app` -- IPFS Gateway: `https://ipfs.4everland.link/ipfs/CID` +Alternatively, add a shebang to your `app.py`: +```python +#!/usr/bin/env python3 +```
---- +
+🔧 "error: hash mismatch in fixed-output derivation" -### Task 4 — IPFS Pinning (4 pts) +**Problem:** The hash you specified doesn't match the actual content. -**Objective:** Use 4EVERLAND's storage (Bucket) for IPFS pinning. +**Solution:** +1. Use `pkgs.lib.fakeHash` initially to get the correct hash +2. Nix will fail and tell you the expected hash +3. Replace `fakeHash` with the correct hash from the error message -**Requirements:** +Example: +```nix +vendorHash = pkgs.lib.fakeHash; # Start with this +# Error will say: "got: sha256-abc123..." +# Then use: vendorHash = "sha256-abc123..."; +``` -1. **Upload Files to Bucket** - - Upload multiple files (images, documents, etc.) - - Get CIDs for each file +
-2. **Create a Directory Structure** - - Upload a folder with multiple files - - Understand directory CIDs +
+🔧 Docker image doesn't load or fails to run + +**Common causes:** + +1. **Image tarball not built:** Check `result` is a `.tar.gz` file + ```bash + file result + # Should show: gzip compressed data + ``` + +2. **Wrong Cmd path:** Verify the app path in docker.nix + ```nix + config.Cmd = [ "${app}/bin/devops-info-service" ]; + # Make sure this matches your installPhase output + ``` -3. **Access via Multiple Gateways** - - Access your content via: - - 4EVERLAND gateway - - Public IPFS gateways (ipfs.io, dweb.link) - - Understand gateway differences +3. **Missing dependencies in image:** Add required packages to `contents` + ```nix + contents = [ app pkgs.coreutils ]; # Add tools if needed + ``` -4. **Verify Pinning** - - Confirm content is pinned - - Understand pinning vs local storage +
-💡 Hints +🔧 Port conflicts when running containers -**Bucket Upload:** -1. Dashboard → Bucket -2. Create new bucket -3. Upload files or folders -4. Get CID from file details +**Problem:** Port 5000 or 5001 already in use. -**Multiple Gateways:** +**Solution:** ```bash -# 4EVERLAND -https://ipfs.4everland.link/ipfs/QmXxx... - -# IPFS.io -https://ipfs.io/ipfs/QmXxx... +# Find what's using the port +lsof -i :5000 -# Cloudflare -https://cloudflare-ipfs.com/ipfs/QmXxx... +# Stop old containers +docker stop $(docker ps -aq) 2>/dev/null -# DWeb.link -https://dweb.link/ipfs/QmXxx... +# Or use different ports +docker run -d -p 5002:5000 --name my-container my-image ``` -**Directory Upload:** -- Upload entire folder -- Get directory CID -- Access files: `gateway/ipfs/DirCID/filename` +
+ +
+🔧 Flakes don't work: "experimental features" error + +**Problem:** Flakes not enabled in your Nix configuration. + +**Solution:** +```bash +# Check if flakes are enabled +nix flake --help -**Pinning Importance:** -- Unpinned content may be garbage collected -- Pinning services keep content available -- Multiple pins = more redundancy +# If error, enable flakes: +mkdir -p ~/.config/nix +echo "experimental-features = nix-command flakes" >> ~/.config/nix/nix.conf + +# Restart terminal +```
---- +
+🔧 Build fails on macOS: "unsupported system" -### Task 5 — IPNS & Updates (3 pts) +**Problem:** Flake hardcodes `x86_64-linux` but you're on macOS. -**Objective:** Understand mutable content with IPNS. +**Solution:** Change the system in `flake.nix`: +```nix +# For Mac Intel: +system = "x86_64-darwin"; -**Requirements:** +# For Mac M1/M2/M3: +system = "aarch64-darwin"; +``` -1. **Understand IPNS** - - IPFS = immutable (content changes = new CID) - - IPNS = mutable pointer to IPFS content - - IPNS name stays same, content can change +
-2. **Explore 4EVERLAND Domains** - - Custom domains for your deployment - - How 4EVERLAND handles updates +
+🔧 "cannot build derivation: no builder for this system" -3. **Update Deployment** - - Make changes to your static site - - Redeploy - - Observe: same URL, new CID +**Problem:** Trying to build Linux binaries on macOS or vice versa. + +**Solution:** Either: +1. Match your system architecture in the flake +2. Use Docker builds which work cross-platform +3. Use Nix's cross-compilation features (advanced) + +
-💡 Hints +🔧 Don't have Lab 1/2 artifacts to use + +**No problem!** Create a minimal example: + +1. **Create simple Flask app:** + ```python + # app.py + from flask import Flask, jsonify + app = Flask(__name__) + + @app.route('/health') + def health(): + return jsonify({"status": "healthy"}) -**IPFS vs IPNS:** -- **IPFS CID:** `QmXxx...` - changes when content changes -- **IPNS Name:** `/ipns/k51xxx...` - stays same, points to current CID + if __name__ == '__main__': + app.run(host='0.0.0.0', port=5000) + ``` -**4EVERLAND Handles This:** -- Your project URL stays constant -- Behind scenes, updates the IPNS pointer -- Users always get latest version +2. **Create requirements.txt:** + ``` + flask + ``` -**Domain Configuration:** -1. Dashboard → Hosting → Your Project -2. Settings → Domains -3. Add custom domain or use provided subdomain +3. **Create basic Dockerfile:** + ```dockerfile + FROM python:3.13-slim + WORKDIR /app + COPY requirements.txt app.py ./ + RUN pip install -r requirements.txt + EXPOSE 5000 + CMD ["python", "app.py"] + ``` + +Now you can proceed with the lab using these minimal examples!
--- -### Task 6 — Documentation & Analysis (3 pts) +## How to Submit -**Objective:** Document your work and analyze decentralized hosting. +1. Create a branch for this lab and push it: -**Create `4EVERLAND.md` with:** + ```bash + git switch -c feature/lab18 + # create labs/submission18.md with your findings + git add labs/submission18.md labs/lab18/ + git commit -m "docs: add lab18 submission - Nix reproducible builds" + git push -u origin feature/lab18 + ``` -1. **Deployment Summary** - - What you deployed - - URLs (4EVERLAND and IPFS gateways) - - CIDs obtained +2. **Open a PR (GitHub) or MR (GitLab)** from your fork's `feature/lab18` branch → **course repository's main branch**. -2. **Screenshots** - - 4EVERLAND dashboard - - Deployed site - - Bucket storage - - Multiple gateway access +3.

+🎯 Understanding Reproducibility + +**What makes a build reproducible?** +- ✅ Deterministic inputs (exact versions, hashes) +- ✅ Isolated environment (no system dependencies) +- ✅ No timestamps or random values +- ✅ Same compiler, same flags, same libraries +- ✅ Content-addressable storage + +**Why traditional tools fail:** +```bash +# Docker - timestamps in layers +docker build . # Different timestamp = different image hash + +# npm - lockfiles help but aren't perfect +npm install # Still uses local cache, system libraries -**Good luck!** 🌐 +# apt/yum - version drift +apt-get install nodejs # Gets different version next week +``` + +**How Nix succeeds:** +```bash +# Nix - pure, sandboxed, content-addressed +nix-build # Same inputs = bit-for-bit identical output + # Today, tomorrow, on any machine +``` -> **Remember:** Decentralized hosting trades some convenience for resilience and censorship resistance. Content-addressed storage ensures integrity - the same content always has the same identifier. +**Real-world impact:** +- **CI/CD:** No more "works on my machine" +- **Security:** Audit exact dependency tree +- **Rollback:** Atomic updates with perfect rollbacks +- **Collaboration:** Everyone gets identical environment + +
+ +
+🌟 Advanced Concepts (Optional Reading) + +**Content-Addressable Store:** +- Every package has a unique hash based on its inputs +- `/nix/store/abc123...` where `abc123` = hash of inputs +- Same inputs = same hash = reuse existing build + +**Sandboxing:** +- Builds run in isolated namespaces +- No network access (except for fixed-output derivations) +- No access to `/home`, `/tmp`, or system paths +- Only declared dependencies are available + +**Lazy Evaluation:** +- Nix expressions are lazily evaluated +- Only builds what's actually needed +- Enables massive codebase (all of nixpkgs) without performance issues + +**Binary Cache:** +- cache.nixos.org provides pre-built binaries +- If your build matches a cached hash, download instead of rebuild +- Set up private caches for your team + +**Cross-Compilation:** +- Nix makes cross-compilation trivial +- `pkgs.pkgsCross.aarch64-multiplatform.hello` +- Same reproducibility guarantees across architectures + +

Dependencies are installed in an earlier layer, so the app has FastAPI/uvicorn available. +- **Layer order:** If we copied everything first and then ran `pip install`, any change to `app.py` would invalidate the cache and re-run `pip install` every time. Putting dependencies first keeps installs cached. +- **Security:** Non-root user, minimal files in the image, no dev/test tooling. `.dockerignore` keeps `.git` and secrets out of the build context. +- **`.dockerignore`:** Reduces context sent to the daemon (faster `docker build`) and prevents `docs/`, `tests/`, `venv/`, `.git` from being considered for `COPY`, so they never end up in the image. + +## 5.

+|---|---| +| `pythonEnv` | Builds a Python runtime with FastAPI, Uvicorn, and prometheus-client from nixpkgs. | +| `stdenvNoCC.mkDerivation` | Creates a derivation for this app without compiling C/C++ code. | +| `pname` / `version` | Names the Nix output as `devops-info-service-1.0.0`. | +| `src` | Uses the current app directory while excluding generated build outputs and virtualenv/cache directories. | +| `nativeBuildInputs` | Adds `makeWrapper` so the executable can run with the pinned Python environment. | +| `installPhase` | Copies `app.py` into the Nix output and creates `bin/devops-info-service`. | +| `meta.mainProgram` | Identifies the default executable for tools that inspect the package. | + +### Build Evidence + +Command run inside the Nix validation container: +
