NGINX acts as a reverse proxy for the Polyaxon's front-end server, meaning NGINX proxies external HTTP (and HTTPS) requests to the Polyaxon API.
The recommended way to use Https in Polyaxon on Kubernetes is by setting an ingress-nginx for the Polyaxon Cluster running on Kubernetes.
Polyaxon's helm chart comes with an ingress resource that you can use with an ingress controller where you should use TLS so that all traffic will be served over HTTPS.
Create a TLS secret that contains your TLS certificate and private key.
kubectl create secret tls polyaxon-tls --key $PATH_TO_KEY --cert $PATH_TO_CERT
Add the tls configuration to Polyaxon's Ingress values.
serviceType: ClusterIP ingress: enabled: true hostName: polyaxon.acme.com tls: - secretName: polyaxon.acme-tls hosts: - polyaxon.acme.com

To enable ssl for Polyaxon API running with NodePort service on Kubernetes, you need to provide an ssl certificate and ssl certificate key.
you can provide a self-signed certificate or a browser trusted certificate.
Create a secret for you certificate:
kubectl create -n polyaxon secret generic polyaxon-cert --from-file=/path/to/certs/polyaxon.com.crt --from-file=/path/to/certs/polyaxon.com.key
Make sure to update you deployment config with reference to the certificate
ssl: enabled: true secretName: 'polyaxon-cert'
Set the service type to
NodePortand update the api's service port to 443.
N.B. By default Polyaxon mounts the ssl certificate and key to
/etc/ssl, this value can be updated using the
The process for using certificate with a Polyaxon deployment on docker or docker compose is quite similar to kubernetes's NodePort service,
you need to mount an ssl certificate and ssl certificate key to
/etc/ssl, and set
POLYAXON_NGINX_ENABLE_SSL to true/1.
If you are serving Polyaxon on HTTPS, you should be aware that CLI need to have a different config:
polyaxon config set --host=IP/Host --http_port=443 --ws_port=443 --use_https=true [--verify_ssl]
