Anthropic Deploy Integration

Overview

Deploy Claude API integrations with proper secret management, health checks, and rollback procedures across Docker, GCP Cloud Run, and Kubernetes.

Docker Deployment

FROM python:3.12-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt
COPY src/ ./src/
ENV ANTHROPIC_API_KEY=""
EXPOSE 8000
CMD ["uvicorn", "src.main:app", "--host", "0.0.0.0", "--port", "8000"]

# src/main.py
from fastapi import FastAPI, HTTPException
import anthropic

app = FastAPI()
client = anthropic.Anthropic()

@app.get("/health")
async def health():
    try:
        count = client.messages.count_tokens(
            model="claude-haiku-4-20250514",
            messages=[{"role": "user", "content": "ping"}]
        )
        return {"status": "healthy", "api": "connected"}
    except Exception as e:
        raise HTTPException(503, detail=str(e))

GCP Cloud Run

echo -n "sk-ant-api03-..." | gcloud secrets create anthropic-key --data-file=-

gcloud run deploy claude-service \
  --image gcr.io/my-project/claude-service \
  --set-secrets ANTHROPIC_API_KEY=anthropic-key:latest \
  --min-instances 1 --max-instances 10 \
  --memory 512Mi --timeout 120s

Kubernetes

apiVersion: apps/v1
kind: Deployment
metadata: { name: claude-service }
spec:
  replicas: 3
  strategy: { type: RollingUpdate, rollingUpdate: { maxUnavailable: 1 } }
  template:
    spec:
      containers:
        - name: app
          env:
            - name: ANTHROPIC_API_KEY
              valueFrom:
                secretKeyRef: { name: anthropic-secrets, key: api-key }
          livenessProbe:
            httpGet: { path: /health, port: 8000 }
            periodSeconds: 30

Rollback

# Cloud Run
gcloud run services update-traffic claude-service --to-revisions=PREVIOUS=100

# Kubernetes
kubectl rollout undo deployment/claude-service

Error Handling

Issue	Cause	Fix
Container crash on start	Missing API key env var	Verify secret binding
Health check fails	Key invalid in prod	Test key with curl
429 after scaling up	More replicas = more RPM	Shared rate limiter (Redis)
