gcloud Skill

Common GCP patterns for the apes platform. All commands invoke gcloud/docker directly via Bash.

Project: apes-platform Region: europe-west1 Zone: europe-west1-b

Current Infrastructure

Service	Host	VM	IP	Compose dir
Gitea	git.unslope.com	gitea-vm	34.78.255.104	/opt/gitea
Colony	apes.unslope.com	colony-vm (e2-medium)	35.241.200.77	/opt/colony-src/infra/colony

SSH into VMs

gcloud compute ssh <vm> --zone=europe-west1-b --project=apes-platform
gcloud compute ssh <vm> --zone=europe-west1-b --project=apes-platform --command="<cmd>"

Colony Deploy

# 1. SSH in and pull latest code
gcloud compute ssh colony-vm --zone=europe-west1-b --project=apes-platform \
  --command='sudo bash -c "cd /opt/colony-src && git pull"'

# 2. Rebuild (deps cached, only source changes recompile ~30s)
gcloud compute ssh colony-vm --zone=europe-west1-b --project=apes-platform \
  --command='sudo bash -c "cd /opt/colony-src/infra/colony && docker compose build 2>&1 | tail -5"'

# 3. Restart
gcloud compute ssh colony-vm --zone=europe-west1-b --project=apes-platform \
  --command='sudo bash -c "cd /opt/colony-src/infra/colony && docker compose up -d"'

# 4. Verify
gcloud compute ssh colony-vm --zone=europe-west1-b --project=apes-platform \
  --command='sudo bash -c "sleep 3 && docker logs colony 2>&1 | tail -5 && curl -s http://localhost:3001/api/health"'

Docker Compose on VMs

# Restart a service
gcloud compute ssh <vm> --zone=europe-west1-b --project=apes-platform \
  --command="sudo bash -c 'cd <compose-dir> && docker compose restart <container>'"

# View logs (use 2>&1 for stderr)
gcloud compute ssh <vm> --zone=europe-west1-b --project=apes-platform \
  --command='sudo docker logs <container> 2>&1 | tail -50'

# Full redeploy
gcloud compute ssh <vm> --zone=europe-west1-b --project=apes-platform \
  --command="sudo bash -c 'cd <compose-dir> && docker compose pull && docker compose up -d'"

Install Docker on Debian 12

gcloud compute ssh <vm> --zone=europe-west1-b --project=apes-platform --command='sudo bash -c "
apt-get update && apt-get install -y ca-certificates curl gnupg git
install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
chmod a+r /etc/apt/keyrings/docker.gpg
echo \"deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian bookworm stable\" > /etc/apt/sources.list.d/docker.list
apt-get update && apt-get install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin
systemctl enable docker && systemctl start docker
"'

Static IPs & DNS

# Reserve IP
gcloud compute addresses create <name> --region=europe-west1 --project=apes-platform

# Get IP
gcloud compute addresses describe <name> --region=europe-west1 --project=apes-platform --format='value(address)'

# DNS: Namecheap → Advanced DNS → Add A Record → host=<subdomain> value=<IP>
# Verify: dig @dns1.registrar-servers.com <domain> A +short

Firewall Rules

gcloud compute firewall-rules list --project=apes-platform
gcloud compute firewall-rules create <name> --allow=tcp:<port> --target-tags=web-server --project=apes-platform
gcloud compute firewall-rules delete <name> --project=apes-platform --quiet

New VM Pattern

gcloud compute instances create <name> \
  --project=apes-platform \
  --zone=europe-west1-b \
  --machine-type=e2-small \
  --image-family=debian-12 \
  --image-project=debian-cloud \
  --boot-disk-size=20GB \
  --tags=web-server \
  --address=<static-ip-name>

Gitea (git.unslope.com)

# Git push/pull: HTTP on port 3000 (no gcloud needed)
git clone http://git.unslope.com:3000/benji/apes.git
git remote set-url origin http://<user>:<token>@34.78.255.104:3000/benji/apes.git

# Create API token
curl -u user:pass -X POST 'https://git.unslope.com/api/v1/users/<user>/tokens' \
  -H 'Content-Type: application/json' -d '{"name":"my-token","scopes":["all"]}'

# Create user (admin only, via SSH)
gcloud compute ssh gitea-vm --zone=europe-west1-b --project=apes-platform \
  --command='sudo docker exec -u git gitea gitea admin user create --username <user> --password "<pass>" --email "<email>"'

Troubleshooting

Error	Fix
SSH timeout	VM under load (e.g. compiling Rust). Wait and retry. Don't kill builds.
SSH connection refused	VM still booting. Wait 30s, retry.
Docker not running	sudo systemctl start docker
Caddy cert failed	Check DNS: dig @dns1.registrar-servers.com <domain> A +short. Clear Caddy data if stuck on staging cert: sudo rm -rf <compose-dir>/caddy_data/caddy/certificates/acme-staging*
Container exits immediately	Check binary size — if < 1MB it's the stub binary. Rebuild with docker rmi <image> && docker compose build
Container restarting, no logs	Binary panicking before first print. Run interactively: docker run --rm -e DATABASE_URL=... <image> /app/<binary>
Git push fails (DNS)	Use IP directly: http://34.78.255.104:3000/benji/apes.git
Git push auth fails	Use API token, not password (special chars break URL encoding)
Build takes forever	First Rust build ~10min on e2-medium. Subsequent builds ~30s (deps cached). Don't use --no-cache unless Dockerfile changed.
Docker build SSH timeout	Build in background: nohup docker compose build > /tmp/build.log 2>&1 & then check later
