Install a Custom Signed Certificate
The NetQ UI ships with a self-signed certificate that is sufficient for non-production environments or cloud deployments. For on-premises deployments, however, you receive a warning from your browser that this default certificate is not trusted when you first log in to the NetQ UI. You can avoid this by installing your own signed certificate.
If you already have a certificate installed and want to change or update it, run the
kubectl delete secret netq-gui-ingress-tls [name] --namespace default command.
You need the following items to perform the certificate installation:
A valid X509 certificate.
A private key file for the certificate.
A DNS record name configured to access the NetQ UI.
The FQDN should match the common name of the certificate. If you use a wild card in the common name — for example, if the common name of the certificate is *.example.com — then the NetQ telemetry server should reside on a subdomain of that domain, accessible via a URL like netq.example.com.
A functioning and healthy NetQ instance.
You can verify this by running the
netq show opta-healthcommand.
Install a Certificate using the NetQ CLI
Log in to the NetQ On-premises Appliance or VM via SSH and copy your certificate and key file there.
Generate a Kubernetes secret called
cumulus@netq-ts:~$ kubectl create secret tls netq-gui-ingress-tls \ --namespace default \ --key <name of your key file>.key \ --cert <name of your cert file>.crt
Verify that you created the secret successfully.
cumulus@netq-ts:~$ kubectl get secret NAME TYPE DATA AGE netq-gui-ingress-tls kubernetes.io/tls 2 5s
Update the ingress rule file to install self-signed certificates.
Create a new file called
Copy and add the following content to the file:
apiVersion: networking.k8s.io/v1 kind: Ingress metadata: annotations: nginx.ingress.kubernetes.io/ssl-redirect: "true" nginx.ingress.kubernetes.io/backend-protocol: "HTTPS" nginx.ingress.kubernetes.io/proxy-connect-timeout: "3600" nginx.ingress.kubernetes.io/proxy-read-timeout: "3600" nginx.ingress.kubernetes.io/proxy-send-timeout: "3600" nginx.ingress.kubernetes.io/proxy-body-size: 10g nginx.ingress.kubernetes.io/proxy-request-buffering: "off" name: netq-gui-ingress-external namespace: default spec: ingressClassName: ingress-nginx-class rules: - host: <your-hostname> http: paths: - path: / pathType: Prefix backend: service: name: netq-gui port: number: 80 path: / pathType: Prefix tls: - hosts: - <your-hostname> secretName: netq-gui-ingress-tls
<your-hostname>with the FQDN of the NetQ VM.
Apply the new rule:
cumulus@netq-ts:~$ kubectl apply -f ingress.yaml ingress.extensions/netq-gui-ingress-external configured
A message like the one above appears if your ingress rule is successfully configured.
Configure the NetQ API to use the new certificate.
kubectl edit ingress netq-swagger-ingress-external
tls:section in the
spec:stanza, referencing your configured hostname and the
spec: rules: - host: <hostname> http: paths: - backend: serviceName: swagger-ui servicePort: 8080 path: /swagger(/|$)(.*) tls: - hosts: - <hostname> secretName: netq-gui-ingress-tls
After saving your changes, delete the current swagger-ui pod to restart the service:
cumulus@netq-ts:~$ kubectl delete pod -l app=swagger-ui pod "swagger-ui-deploy-69cfff7b45-cj6r6" deleted
Your custom certificate should now be working. Verify this by opening the NetQ UI at
https://<your-hostname-or-ipaddr> in your browser.
