What is Apigee CI/CD and how do you deploy proxies in a pipeline?

# Method 1: apigeecli (official Google CLI tool)

# Import a proxy bundle:
apigeecli apis create bundle \
  --name orders-proxy \
  --proxy-zip ./orders-proxy.zip \
  --org my-org \
  --token $(gcloud auth print-access-token)

# Deploy to an environment:
apigeecli apis deploy \
  --name orders-proxy \
  --env prod \
  --org my-org \
  --rev 3 \
  --token $(gcloud auth print-access-token)

# Method 2: Apigee Management API (REST)
curl -X POST \
  "https://apigee.googleapis.com/v1/organizations/my-org/apis?action=import&name=orders-proxy" \
  -H "Authorization: Bearer $(gcloud auth print-access-token)" \
  -H "Content-Type: multipart/form-data" \
  -F "file=@orders-proxy.zip"

# Method 3: Maven plugin (in pom.xml)
# <plugin>
#   <groupId>com.apigee.edge</groupId>
#   <artifactId>apigee-edge-maven-plugin</artifactId>
#   <configuration>
#     <org>my-org</org>
#     <env>prod</env>
#   </configuration>
# </plugin>

# Typical CI/CD pipeline:
# 1. Developer pushes proxy to Git
# 2. CI lints the proxy bundle (apigeelint)
# 3. CI runs unit tests (apickli / Mocha)
# 4. CI packages and deploys to test environment
# 5. Integration tests run against test
# 6. Manual approval gate
# 7. Deploy to prod
