A6 Persona Operator

Daily Operations Checklist

1. Health check

# Verify APISIX is reachable and get version
a6 health

# Check all upstream health status
a6 upstream list --output json | jq '.[] | {id: .id, name: .name}'
a6 upstream health <upstream-id>

2. Configuration audit

# Dump current state
a6 config dump > current-state.yaml

# Compare with expected state
a6 config diff -f expected-state.yaml

# Validate a config file before applying
a6 config validate -f new-config.yaml

3. Certificate management

# List SSL certificates and check expiry
a6 ssl list

# Upload a new certificate
a6 ssl create -f - <<'EOF'
{
  "cert": "-----BEGIN CERTIFICATE-----\n...\n-----END CERTIFICATE-----",
  "key": "-----BEGIN RSA PRIVATE KEY-----\n...\n-----END RSA PRIVATE KEY-----",
  "snis": ["api.example.com", "*.example.com"]
}

Deployment Workflow

Safe deployment pattern

# 1. Validate the config locally
a6 config validate -f new-config.yaml

# 2. Preview what will change
a6 config diff -f new-config.yaml

# 3. Apply to staging first
a6 --context staging config sync -f new-config.yaml

# 4. Verify staging
a6 --context staging health
a6 --context staging route list

# 5. Apply to production
a6 --context prod config sync -f new-config.yaml

# 6. Verify production
a6 --context prod health

Rollback

# Keep a backup before every deployment
a6 config dump > backup-$(date +%Y%m%d-%H%M%S).yaml

# Rollback by syncing the backup
a6 config sync -f backup-20260308-143000.yaml

Troubleshooting

Request not reaching upstream

# 1. Check if the route exists
a6 route list
a6 route get <route-id> --output json

# 2. Trace the request path
a6 debug trace --uri /api/v1/users --method GET

# 3. Stream error logs in real-time
a6 debug logs --follow

# 4. Check upstream health
a6 upstream health <upstream-id>

502 Bad Gateway

# Check upstream node health
a6 upstream get <upstream-id> --output json

# Verify backend is reachable from APISIX
a6 debug trace --uri /failing-endpoint

# Check error logs for connection refused / timeout
a6 debug logs --follow --level error

Authentication failures (401/403)

# Verify consumer exists and has correct credentials
a6 consumer list
a6 consumer get <username> --output json

# Check the route's auth plugin configuration
a6 route get <route-id> --output json | jq '.plugins'

# Check global rules that might override
a6 global-rule list --output json

Security Hardening

Global rate limiting

a6 global-rule create -f - <<'EOF'

      "key_type": "var",
      "key": "remote_addr",
      "rejected_code": 429
    }
  }
}

Global IP restriction

a6 global-rule create -f - <<'EOF'
{
  "id": "global-ip-block",
  "plugins": {
    "ip-restriction": {
      "blacklist": ["10.0.0.0/8", "192.168.0.0/16"]
    }
  }
}
EOF

Enforce CORS globally

a6 global-rule create -f - <<'EOF'
{
  "id": "global-cors",
  "plugins": {
    "cors": {
      "allow_origins": "https://app.example.com",

      "allow_headers": "Authorization,Content-Type",
      "max_age": 3600
    }
  }
}

Monitoring Setup

Enable Prometheus metrics

# Global rule to expose metrics for all routes
a6 global-rule create -f - <<'EOF'
{
  "id": "prometheus-metrics",
  "plugins": {
    "prometheus": {}
  }
}
EOF

Scrape metrics at http://apisix:9091/apisix/prometheus/metrics.

Add HTTP logging

a6 global-rule create -f - <<'EOF'
{
  "id": "http-logging",
  "plugins": {
    "http-logger": {
      "uri": "http://log-collector:9200/_bulk",
      "batch_max_size": 1000,
      "inactive_timeout": 5
    }
  }
}
EOF

Decision Framework

Best Practices

1. Always dump before sync — a6 config dump > backup.yaml before every deployment
2. Validate before apply — a6 config validate -f config.yaml catches errors early
3. Diff before sync — a6 config diff -f config.yaml shows exactly what will change
4. Stage before prod — always apply to staging first, verify, then promote to production
5. Use global rules sparingly — they apply to ALL routes; prefer per-route plugins
6. Monitor upstream health — enable active health checks on critical upstreams
7. Keep contexts organized — name contexts clearly (prod, staging, dev) and verify the current context before destructive operations
8. Version control configs — store YAML configs in git for audit trail and rollback
