## Summary Follow-up on [#220](#220) / [#221](#221). Makes fail2ban **opt-in** in [`70-hardening.sh`](docs/setup/scripts/70-hardening.sh) instead of installing it unconditionally. Reasoning: some corp environments already ship brute-force protection at the network layer (ACL / corp firewall / appliance) — fail2ban on the host then becomes redundant and can be the wrong layer to debug from when a rule misfires. The other three hardening steps (UFW enable, sshd lockdown) were already prompt-gated; fail2ban was the odd one out. ## What lands | File | Change | | --- | --- | | `docs/setup/scripts/70-hardening.sh` | fail2ban block restructured into three branches: (1) already running → skip; (2) installed but stopped → prompt to enable+start; (3) not installed → prompt to install+enable+start. Each "no" path logs `↪ skip (user choice)` so re-runs don't repeatedly nag if the dev has already declined. | | `docs/setup/01-dev-debian-vm-setup.md` | Table row for `70-hardening.sh` clarified — each sub-step's prompt posture is now visible: UFW prompts before enabling, fail2ban prompts before installing, sshd hardening prompts before applying. `unattended-upgrades` is the only one applied unconditionally. | | `docs/setup/README.md` | Same descriptor adjustment. | ## Test plan - [ ] On a fresh Debian VM with no fail2ban installed, run `70-hardening.sh`, decline the fail2ban prompt → script continues, fail2ban not installed, no service started. - [ ] On the same VM, re-run `70-hardening.sh` → the fail2ban branch prompts again (the dev may have changed their mind); declining again produces the same `↪ skip (user choice)` result. - [ ] On a VM where fail2ban is pre-installed but stopped (rare, but possible if infra rolled it back), the script offers to start it without re-installing. - [x] `pnpm exec prettier --check` clean on the touched files. - [x] `bash -n docs/setup/scripts/70-hardening.sh` (syntax check) clean. --------- Co-authored-by: Julien Gautier <julien.gautier@apf.asso.fr> Reviewed-on: #222
Setup guides
Step-by-step setup procedures for new contributors. Each file is self-contained and idempotent — they document the state a developer should reach, not the order in which it must be done.
| # | File | Audience |
|---|---|---|
| 01 | Debian 13 dev-VM setup | Default — a dev who has just received a fresh dev VM from the infra team. Covers the full path: zsh + Oh My Zsh + Powerlevel10k, modern CLI tooling, Node via nvm, Docker CE, system tuning, optional VM hardening, project clones, the two IDE flows (VSCode Remote-SSH and Devcontainer), the hybrid (local + VM) mode. |
| 02 | WSL terminal setup | Legacy — the original Windows-WSL flow. Kept for reference for devs still on that path until the org migrates to the VM-based flow. |
| 03 | Dev web stack | Notes on the web-side tooling. |
| 04 | Angular + Nx monorepo | Reference notes on the Angular + Nx workspace layout. |
scripts/
Modular setup scripts called from the doc above. Each is idempotent, each can be re-run safely. Run via the orchestrator (bootstrap.sh) or individually.
| Script | Purpose |
|---|---|
bootstrap.sh |
Run every numbered script in order with a confirmation prompt at each step. |
lib.sh |
Common helpers — colour logging, idempotent apt_install / ensure_line. |
10-base-packages.sh |
apt + base packages every other script assumes (curl wget git build-essential …). |
20-zsh.sh |
zsh + Oh My Zsh + Powerlevel10k + autosuggestions + syntax-highlighting. Patches ~/.zshrc (theme / plugins / fzf hook) and ~/.bashrc (exec zsh — chsh blocked on corp VM). |
30-cli-tools.sh |
bat eza fd-find ripgrep fzf zoxide ncdu keychain + dev extras (jq yq httpie make tree htop tmux direnv). |
40-node.sh |
nvm + Node from the repo's .nvmrc + corepack pinned to package.json#packageManager's pnpm version. |
50-docker.sh |
Docker CE + compose plugin from docker.com apt repo + user added to docker group + service enabled at boot. |
60-tuning.sh |
inotify watches → 524288, optional 4 GB swapfile, optional hostname rename (only prompts if generic). |
70-hardening.sh |
Best-effort UFW + unattended-upgrades + fail2ban (opt-in) + sshd hardening drop-in. Probes before applying — skips done items, prompts before each install. |
80-dotfiles.sh |
Symlinks notes/aliases.zsh → ~/.oh-my-zsh/custom/aliases.zsh. Copies notes/gitconfig.txt to ~/.gitconfig with prompted identity. |
systemd/
| File | Purpose |
|---|---|
apf-portal-infra@.service |
Template unit auto-starting ./infra/local/dev.sh up at boot for a given user. |
