kandi X-RAY | dpt Summary

dpt is a C++ library. dpt has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

dpt is a prototypical renderer that implements the algorithm presented in the paper "[Anisotropic Gaussian Mutations for Metropolis Light Transport through Hessian-Hamiltonian Dynamics] (by Tzu-Mao Li, Jaakko Lehtinen, Ravi Ramamoorthi, Wenzel Jakob, and Frédo Durand. The algorithm utilizes the derivatives of the contribution function of a (bidirectional) path tracer to guide local sampling, hence the name dpt. dpt supports a limited form of mitsuba's scene format. It supports pinhole camera, three kinds of BSDF (diffuse, phong, roughdielectric), three kinds of emitters (point, area, envmap), trianglemesh shape, and linear motion blur. See scenes/torus for an example scene. If you want to understand the algorithm by looking at the source code, a good starting point is to look at mlt.cpp, h2mc.cpp, and path.cpp first. dpt uses tup as its build system. It depends on several libraries: Eigen, OpenImageIO, embree, and zlib. It uses ispc to compile the derivative code it generates. It also uses pugixml to parse the scene file and PCG for fast and high-quality random number generation. A large portion of dpt is inspired by mitsuba, pbrt-v3, and SmallVCM. dpt needs to generate a dynamic library that contains functions for computing the derivatives of the path contribution function. Before you execute dpt, you will need to specify the directory used for reading/writing the dynamic library by setting the environment variable DPT_LIBPATH (e.g. export DPT_LIBPATH=/path/to/dpt/src/bin). dpt will search that directory for the dynamic library, and if it does not find it, it will create one. The program is only tested on OSX 10.10.5 with clang and Ubuntu 14.04 with gcc. Currently it does not support windows system. Please contact Tzu-Mao Li (tzumao at mit.edu) if there are any issues/comments/questions.

QUESTION

Is there a way to configure Docker's embedded DNS server's upstream nameserver's port?

Asked 2021-Apr-27 at 01:18

General context

Docker daemon comes with an embedded DNS server. It resolves local Docker swarm and network records and forwards queries for external records to an upstream nameserver configured with --dns 1.

Docs say you can set an IP address for this upstream nameserver with --dns=[IP_ADDRESS...]. The default port used is 53.

My question

Can I configure the port used as well?

My host's /etc/docker/daemon.json shows "dns": ["10.99.0.1"],. Is there a way for me to specify something like "dns": ["10.99.0.1:53"], so that dockerd always knows to forward DNS queries to port 53?

My use case

In my case, 10.99.0.1 is the IP of a localhost bridge interface. I run a local DNS caching server on this host. So DNS queries sent to 10.99.0.1:53 work. But dockerd forwards queries originating from containers connected to user-defined bridge networks (created with docker network create) to non-standard ports it picks. See terminal output below.

Detailed terminal output and debugging info

"toogle" is a Docker container connected to a Docker network I created with docker network create. 127.0.0.11 is another loopback address. DNS queries originating from within Docker containers connected to user-defined Docker networks are destined for this IP.

Is Docker's embedded DNS server actually running?

DNS queries are routed by toogle's firewall rules this way.

I don't think there's a way to do this. I also misread the output. Docker daemon was forwarding to port 53.

Answered 2021-Apr-02 at 13:55

Not enough for comment so this is why: From what it seems it could be either firewall rule in your host running the container or one between the host to your house. To test which on between the two I'd try to use nmap with --reason and --tracerout options, since we have connectivity in another port it's unlikely that there is a complete block between your home and the container so the traceroute wouldn't give much info but just in case. Also if you have root access to the host machine or just to the iptables service try to stop it to check if that's the root cause for the block.

also check with docker ps if the port is bound to the port on the machine, should look something like this:

0.0.0.0:port --> tcp\port

where instead of port you have the port number

If it doesn't maybe it's due to some problem with the docker-compose up command so try to run the service with a simple docker run command

Read configmap from a k8s program

I’ve a go program which need to access to config map, when using the following clusterRole we got error forbidden

...

ANSWER

Answered 2021-Mar-30 at 23:09

Each Kubernetes resource is part of some API group. The API group defines the path on which these resources are available. You can find them for example in the Kubernetes API reference (for each resource you have the group, version and kind).

As you can see here, for example for ConfigMap the group is core. The group into which the resource belongs needs to be used in the ClusterRole (or Role) when referencing the resources. That is needed to properly specify which resource you are talking about since the resource name is not necessarily unique on its own but only in combination with the group.

Normally, the group is just written there, but for the core group, you normally just put there "" (as described here).

So in your examples, this:
