I've set up a K3D cluster with Traefik, but I'm encountering an error in the Traefik pod logs: `Error configuring TLS: secret my-ns/my-app-tls-cert-ingress does not exist`. I understand what this error means, but do I just need to create a PEM file and apply that as a secret with the specified name and namespace? If so, does the PEM file need to include the entire certificate chain along with the key?

Yes, that's right! Just make sure you have the public certificate and private key in PEM format. The CA issuer isn't necessary for the TLS secret itself, but you'll need it on the client side to trust your certificate.
I'm facing a similar issue. After creating the secret, I started getting an internal server error. No logs are being produced from my app, so I'm a bit lost about which container I'm hitting, though removing SSL seems to solve it.
You'll need to create a TLS secret that matches the name and namespace Traefik expects. Make sure to include the certificate and the private key in PEM format. You can run this command to create the secret:
```
kubectl create secret tls my-app-tls-cert-ingress
--cert=cert.pem
--key=key.pem
-n my-ns
```
Once you've done that, Traefik should automatically pick up the secret once it exists.
