Caseware — Ilia Dobkin portfolio site

Static one-page site for CaseWare / CaseView consulting work. No build step — plain HTML and CSS.

File	Purpose
index.html	Page content and structure
styles.css	Layout, typography, theme

Live site: https://caseware.levkin.ca
Booking: https://cal.levkin.ca/ilia/consult

---

Local development

cd caseware
python3 -m http.server 8765
# Open http://localhost:8765

Or open index.html directly in a browser (some features work best over HTTP).

Production deployment

Traffic flow:

Internet → Caddy (caseware.levkin.ca) → LXC 215 (nginx :80) → /var/www/caseware

Component	Details
Proxmox host	PVENAS
Container ID	215
Hostname	caseware
IP	10.0.10.105 (DHCP on vmbr0)
Gateway	10.0.10.1
Web root	/var/www/caseware
Web server	nginx

Caddy (on separate server)

caseware.levkin.ca {
    reverse_proxy 10.0.10.105:80
}

Reload after edits: systemctl reload caddy

Create LXC 215 (reference — already done)

pct create 215 local:vztmpl/debian-12-standard_12.12-1_amd64.tar.zst \
  --hostname caseware \
  --memory 512 \
  --swap 256 \
  --cores 1 \
  --rootfs local-lvm:4 \
  --net0 name=eth0,bridge=vmbr0,ip=dhcp \
  --unprivileged 1 \
  --onboot 1 \
  --start 1

pct exec 215 -- hostname -I   # note the IP (10.0.10.105)

Shell access to the container

No default root password. From Proxmox:

pct enter 215

---

First-time setup inside CT 215

apt update && apt install -y git nginx openssh-client

# SSH key for Gitea (add public key in Gitea → Settings → SSH Keys)
ssh-keygen -t ed25519 -N "" -f /root/.ssh/id_ed25519
cat /root/.ssh/id_ed25519.pub
ssh -o StrictHostKeyChecking=accept-new -T gitea@10.0.30.169

mkdir -p /var/www/caseware
git clone gitea@10.0.30.169:ilia/caseware.git /var/www/caseware
chown -R root:root /var/www/caseware
chmod 755 /var/www/caseware
chmod 644 /var/www/caseware/index.html /var/www/caseware/styles.css

nginx site config

cat > /etc/nginx/sites-available/caseware <<'EOF'
server {
    listen 80 default_server;
    listen [::]:80 default_server;
    server_name _;
    root /var/www/caseware;
    index index.html;

    location / {
        try_files $uri $uri/ =404;
    }
}
EOF

ln -sf /etc/nginx/sites-available/caseware /etc/nginx/sites-enabled/caseware
rm -f /etc/nginx/sites-enabled/default
nginx -t && systemctl enable --now nginx

---

Deploy updates (pull on server)

From Proxmox:

pct exec 215 -- bash -c 'cd /var/www/caseware && git pull'

Or inside the container:

pct enter 215
cd /var/www/caseware && git pull
exit

Hard-refresh the browser (Cmd+Shift+R) after deploy.

---

Troubleshooting (issues we hit)

1. git clone asks for password / “not a git repository”

Cause: Container had no SSH key registered in Gitea.

Fix:

1. Generate key inside 215: ssh-keygen -t ed25519 -N "" -f /root/.ssh/id_ed25519
2. Add cat /root/.ssh/id_ed25519.pub to Gitea (user ilia) → SSH Keys
3. Test: ssh -T gitea@10.0.30.169 — should say “Hi there, ilia!” with no password
4. Clone: git clone gitea@10.0.30.169:ilia/caseware.git /var/www/caseware

Do not rely on cloning on the Proxmox host unless you prefer that workflow — clone inside 215 with its own key (named e.g. caseware in Gitea).

---

2. fatal: detected dubious ownership in repository

Cause: chown -R www-data:www-data /var/www/caseware made the repo owned by www-data while git pull runs as root.

Fix (recommended): Repo owned by root; nginx only needs read access:

chown -R root:root /var/www/caseware
chmod 755 /var/www/caseware
chmod 644 /var/www/caseware/index.html /var/www/caseware/styles.css

Alternative: git config --global --add safe.directory /var/www/caseware

---

3. “Welcome to nginx!” instead of the site

Cause: Default site still enabled; root pointed at /var/www/html.

Fix: Enable caseware site config (see above), remove sites-enabled/default, nginx -t && systemctl reload nginx.

Verify: curl -s http://127.0.0.1/ | head -5 should show <!doctype html> and “Ilia Dobkin”.

---

4. Wrong network assumptions

Lab LAN uses 10.0.10.0/24 (gateway 10.0.10.1 on vmbr0), not 10.0.30.x.
Gitea lives at 10.0.30.169 — different subnet; routing must allow 215 → Gitea.

Container IP from DHCP: pct exec 215 -- hostname -I → currently 10.0.10.105.

---

5. LinkedIn link 404

These URLs do not work:

• https://www.linkedin.com/in/idobkin/
• https://www.linkedin.com/in/iliadobkin/

Working profile in site:

• https://www.linkedin.com/in/ilia-dobkin-8263343/

---

6. No root password on LXC

Expected. Use pct enter 215 from Proxmox. Set passwd root only if you need SSH from other machines.

---

7. curl not found inside container

Install optionally: apt install -y curl
Or test from Proxmox host: curl -I http://10.0.10.105/

---

Quick reference

Task	Command
Enter container	pct enter 215
Container IP	pct exec 215 -- hostname -I
Pull latest	pct exec 215 -- bash -c 'cd /var/www/caseware && git pull'
Test site	curl -I http://10.0.10.105/
nginx reload	pct exec 215 -- systemctl reload nginx

---

Optional improvements (not done yet)

• og:image for LinkedIn/Slack link previews
• Mobile nav for small screens
• DHCP reservation for 215 so 10.0.10.105 stays stable (or set static IP in Proxmox)
