kandi X-RAY | mcrt Summary

mcrt is a C++ library typically used in User Interface, Graphics applications. mcrt has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

. A Monte Carlo raytracer produces photorealistic images of given scenes (given good assets and enough time to fully converge). It’s a technique which allows global illumination, giving optical effects such as color bleeding, hard and soft shadows and caustics. In this repository you’ll find a full Monte Carlo raytracer implementation written in modern C++, along with the accompaying paper [Monte Carlo Raytracing from Scratch] which describes the theory and practical details needed to both understand and implement your own raytracer, along with some benchmarks, reflections and future work. Our raytracer is written from the ground up, and doesn’t need any libraries to be linked. We’ve used the header only libraries: g-truc/glm (for vector and matrix operations), nlohmann/json (for our scene loader) and syoyo/tinyobjloader (for loading meshes).

QUESTION

Google managed SSL certificate stuck on "Provisioning" with FAILED_NOT_VISIBLE for domains

Asked 2022-Feb-15 at 08:14

Following this tutorial, I have deployed an app on GKE, in a regional auto-pilot cluster. I made it publicly accessible using an ingress linked to a domain I own, with a static IP, and a Google Managed Certificate for HTTPS.

Accessing my app by the ip, or my domain name works well in HTTP, but when using HTTPS, I get a ERR_SSL_VERSION_OR_CIPHER_MISMATCH mydomain.com uses an incompatible protocol error (I have this error using the IP, and also using the domain). Indeed, when consulting my managed certificate on the Google Cloud Cnsole I see that it is still in PROVISIONING status (it has been more than 3 days now), and I have a warning triangle next to my domain specifying FAILED_NOT_VISIBLE.

I have checked my domain name setup and it has a A record pointing to the static IP used by my ingress (I configured it while doing the tutorial). I've also checked my load balancer on GKE and it has a target proxy for HTTPS using my managed certificate

Here is my ingress

So it looks like it was due to a misconfiguration on my DNS. I added the A record, but when taking a closer look at the update DNS part, I noticed that my CNAME record was misconfigured

QUESTION

GKE Nginx Ingress controller's Ingress not binding to External IP

Asked 2022-Jan-10 at 07:51

I'm trying to add an NGINX Ingress controller on a GKE cluster, with existing HAProxy Ingress controller (which has some problem with rewriting rules)

First I tried to expose the controller's Service to LoadBalancer type. The traffic can reach ingress and backends, but it didn't work with Managed Certificates.

So I tried to use L7 Load Balancer (URL Map) to forward traffic to GKE cluster IP, and create an Ingress object for my ingress controller itself.

The problem is, this Ingress object seems not bound to external IP. And routing to the domain yields "default backend - 404" response.

ANSWER

Answered 2022-Jan-07 at 10:41

Managed Certificates only work with L7 (HTTP) LoadBalancer not with TCP ones.

My understanding is you want to use nginx as an Ingress controller on GKE but you want to expose it behind an L7 LoadBalancer so you can use Google Managed Certificates ?

I still do not understand why this was broken, or why the following fixed it.

I simplified my Ingress to not have any annotations and applied that:

QUESTION

GKE Ingress shows unhealthy backend services

Asked 2020-Oct-05 at 07:53

I have a GKE cluster with 4 nodes in an instance group. I deployed Ingress and several pods (1 replica only of each pod so they are only on 1 node). I notice on the Google Console (Ingress details page) that all backend services remain Unhealhy although the healthchecks on the running pods are OK and my application is running. To my understanding it says it is unhealthy because out of the 4 nodes, only 1 node is running an instance of a given pod (on the Back-end service details it says "1 of 4 instances healthy"). Am I correct and should I worry and try to fix this? It's bit strange to accept an Unhealthy status when the application is running...

Edit: After further investigation, down to 2 nodes, and activating the healthcheck logs, I can see that the backend service status seems to be the status of the last executed healthcheck. So if it checks last the node that hosts the pod, it is healthy, else it is unhealthy.

GKE version: 1.16.13-gke.1

Please check your yaml file for your service. If it shows externalTrafficPolicy: local, then it is expected behavior.

Local means traffic will always go to a pod on the same node, while everything else is dropped. So if your deployment has only 1 replica it is serving, you will only have one healthy instance.

You can easily test that theory, scale up to 2 replicas and observe behavior. I forsee 1 healthy instance if 2nd replica lands on the same node as first replica and 2/4 healthy if 2nd replica lands on a different node. Let me know.

GKE Ingress backends marked as "Unhealthy"

Asked 2020-Mar-09 at 04:13

I am learning how to use an ingress to expose my application on Google Kubernetes Engine. I followed several tutorials and had a rough setup of what is needed. However, I have no clue why are my service is marked as unhealthy despite them being accessible from the NodePort service I defined directly.

Here is my deployment file: (I removed some data but the most of it remains the same)

Answered 2020-Mar-09 at 04:13

By tinkering with the Readiness and Liveliness probe by adding a successThreshold and FailureThreshold, I managed to get my ingress working. It might be because my application needs a little more buffer time to run.

Managed Certificate in Ingress, Domain Status is FailedNotVisible

I'm simply following the tutorial here: https://cloud.google.com/kubernetes-engine/docs/how-to/managed-certs#creating_an_ingress_with_a_managed_certificate

Everything works fine until I deploy my certificate and wait 20 minutes for it to show up as:

I was successful in using Managedcertificate with GKE Ingress resource.

Let me elaborate on that:

Steps to reproduce:

Create IP address with gcloud
Update the DNS entry
Create a deployment
Create a service
Create a certificate
Create a Ingress resource

Create IP address with gcloud

Invoke below command to create static ip address:

$ gcloud compute addresses create example-address --global

Check newly created IP address with below command:

$ gcloud compute addresses describe example-address --global

Update the DNS entry

Go to GCP -> Network Services -> Cloud DNS.

Edit your zone with A record with the same address that was created above.

Wait for it to apply.

Check with $ nslookup DOMAIN.NAME if the entry is pointing to the appropriate address.

Create a deployment

Below is example deployment which will respond to traffic:
