OpenShift Routes Skill

Manage OpenShift routes for exposing services externally.

When to Use

• Exposing services externally
• Configuring TLS/SSL
• Troubleshooting route access
• Setting up custom domains

Quick Commands

View Routes

# All routes
oc get routes -A

# Routes in namespace
oc get routes -n <namespace>

# Route details
oc describe route <route-name> -n <namespace>

Create Routes

# Simple route (edge TLS)
oc expose svc/<service-name> -n <namespace>

# With custom hostname
oc expose svc/<service-name> -n <namespace> --hostname=myapp.example.com

# Edge TLS (terminate at router)
oc create route edge <route-name> --service=<service-name> -n <namespace>

# Passthrough TLS (end-to-end)
oc create route passthrough <route-name> --service=<service-name> -n <namespace>

# Reencrypt TLS
oc create route reencrypt <route-name> --service=<service-name> \
  --dest-ca-cert=ca.crt -n <namespace>

Get Route URL

# Get host
oc get route <route-name> -n <namespace> -o jsonpath='{.spec.host}'

# Full URL
echo "https://$(oc get route <route-name> -n <namespace> -o jsonpath='{.spec.host}')"

# Test access
curl -k "https://$(oc get route <route-name> -n <namespace> -o jsonpath='{.spec.host}')"

Modify Routes

# Add TLS
oc patch route <route-name> -n <namespace> -p '{"spec":{"tls":{"termination":"edge"}}}'

# Change target port
oc patch route <route-name> -n <namespace> -p '{"spec":{"port":{"targetPort":"8080-tcp"}}}'

# Set path
oc patch route <route-name> -n <namespace> -p '{"spec":{"path":"/api"}}'

TLS Termination Types

Troubleshooting

Route Not Accessible

# Check route status
oc describe route <route-name> -n <namespace>

# Check service exists
oc get svc <service-name> -n <namespace>

# Check service has endpoints
oc get endpoints <service-name> -n <namespace>

# Check pod is running
oc get pods -n <namespace> -l <selector>

# Check router logs
oc logs -n openshift-ingress deployment/router-default | grep <route-host>

Certificate Issues

# Check route TLS config
oc get route <route-name> -n <namespace> -o jsonpath='{.spec.tls}'

# Check certificate expiry
echo | openssl s_client -connect <route-host>:443 2>/dev/null | openssl x509 -noout -dates

# View certificate
echo | openssl s_client -connect <route-host>:443 2>/dev/null | openssl x509 -noout -text

DNS Issues

# Check DNS resolution
nslookup <route-host>
dig <route-host>

# Check wildcard DNS
oc get ingresscontroller default -n openshift-ingress-operator -o jsonpath='{.status.domain}'

Common Patterns

Expose Kagenti UI

# Create route for UI
oc expose svc/kagenti-ui -n kagenti-system

# Get URL
echo "https://$(oc get route kagenti-ui -n kagenti-system -o jsonpath='{.spec.host}')"

Expose Agent Service

# Create edge route with TLS
oc create route edge weather-service \
  --service=weather-service \
  -n team1

# Get agent URL
export AGENT_URL="https://$(oc get route weather-service -n team1 -o jsonpath='{.spec.host}')"
