Introduction

I am quite new to NestJS, but really like how powerful it is so far, so I wanted to see how far I could get with using Kafka, gRPC and NestJS together.

My end goal is to have the following design, since I want to replicate my Kafka Producers:

QUESTION

GRPC service inside Kubernetes is working but fails with an GRPC protocol error when we use istio

Asked 2021-Nov-24 at 16:09

I have a server to server calls and I use GRPC (with .net core 5) It's working and test in local.

After that, I have moved all the services to Kubernetes Pod (Docker Desktop) and also tested through the flow (with swagger post-call) and it's working there too.

Now for monitoring, I added ISTIO and added the label to my namespace "istio-injection=enabled" restarted all my pods and now all are having 2 containers inside each pod.

I tested the basic services (again swagger) and it's working. when it comes to testing the GRPC call. The call is failing from the caller side saying

Grpc.Core.RpcException: Status(StatusCode="Unavailable", Detail="upstream connect error or disconnect/reset before headers. reset reason: protocol error")

I checked the logs at GRPC server-side and it has no clue about this call and the service is just running. then I am kind of thinking that error is coming from the caller side whereas it is not able to or make a call to GRPC server.

The error detail:

Answered 2021-Nov-24 at 16:09

I found a solution at https://istiobyexample.dev/grpc/ where it describes the missing item.

istio recommends using the name and version tag as Label but more importantly when working with GRPC, the service that exposes the GRPC needs to have the port name GRPC.

I have added that restarted the service and it got started working as expected. Again it's not something I resolved. All credit goes to the link https://istiobyexample.dev/grpc/ and the image posted below.

You need to @Autowire the HelloProducer as well - you are creating a new instance (that is not managed by Spring, so it doesn't get any auto wiring).

[@artur's] comment got me thinking and I have finally figured it out. Actually, even before I posted this question, my first thought was that this should indeed be http, despite the documentation saying otherwise, but no, http://127.0.0.1:5020 wouldn't work. So I tried to put it in .toml file instead, I have even tried with https, but also without luck. Trying with http didn't throw any errors, unlike in the case when address was preceeded with tcp, it was just hanging on Waiting for Echo message (similarly to when pointing to the wrong address, which was weird). I've been always, eventually reverting to the tcp version. The solution was simple, remove protocol altogether...

The documentation doesn't give any clues, so for completion, at least when working with C# (.NET 5), there are 3 things that you HAVE TO DO to make it work, all of them are trivial but you have to figure them out by yourself first:

Remove protocol from your configuration when pointing to the proxy app: tcp://127.0.0.1: should be 127.0.0.1: and YES, it will throw regardless if you have protocol specified in the .toml file or as a flag in the console.
The flag is --proxy_app NOT --proxy-app.
Additionally to following the tutorial, you also have to EXPLICITLY override and implement Info(), Echo() and InitChain(), otherwise it will throw an Unimplemented Exception.

Since my understanding of Tendermint is still scarce, the initial approach had some design issues. Here is the code for anybody facing similar problems:

Just updated to Android Studio 4.2.1 on Mac and now emulator no longer works

Asked 2021-Jul-16 at 15:58

I just updated Android Studio to its latest version 4.2.1 and the emulator stopped working. Every time I try to launch a new virtual device it crashes and AVD Manager shows me this error:

"The emulator process for AVD Pixel_C_API_30 was killed"

Here is what I have tried so far:

Cold boot restart.
Deleted and recreated the virtual device inside AVD manager.
Removed and re-installed the emulator SDK package (version 30.7.4)
Quit and restarted Android Studio as well as the emulator.
Created a new virtual device from scratch.
Tried several different virtual devices.

All of the above gives me the same exact result: the emulator crashes and AVD manager shows me the error above.

And here is the error I get from MacOS (just the an excerpt of it):

Grpc throws deadline exceeded after negative number of seconds from now

First calls usually successful, but then I have exception with message like those:

Why is the number of seconds negative? How do I fix it?

My grpc config:

ANSWER

Answered 2021-Jul-01 at 10:56

Deadline is an absolute point in time and is set immediately when you create your stub (and not necessarily when you execute it) - this is in contrast to timeouts which are relative to the start of the call.

So negative deadline means that it expired before your stub was executed.

To fix the issue, you should be setting deadline immediately before making a call.

QUESTION

Android emulator freeze my whole system when it can't connect to adb daemon

Asked 2021-Jun-07 at 13:47

I recently changed my computer and took the opportunity to move from Mageia to Fedora. But I can't do any Android development anymore because, as stated in the title, starting any AVD makes the whole system to freeze (screen, mouse and keybord) if the AVD can't connect to adb daemon. The only thing I can do is hard shutdown.

The problem here is adb daemon is always started when I try to launch an AVD as the service is enabled by default, so that shouldn't happen.

What I've been able to collect so far is a few logs in a file by lauching the emulator from command-line. All it says before freezing is:

emulator: INFO: GrpcServices.cpp:301: Started GRPC server at 127.0.0.1:8554, security: Local
emulator: ERROR: AdbHostServer.cpp:102: Unable to connect to adb daemon on port: 5037

But, if I manually restart the adb service just before lauching the AVD, I don't experience the freeze. Instead, I get the following errors before the AVD crashes:

cannot add library .../android-sdk-linux/emulator/qemu/linux-x86_64/lib64/vulkan/libvulkan.so: failed
added library .../android-sdk-linux/emulator/lib64/vulkan/libvulkan.so
cannot add library .../android-sdk-linux/emulator/lib64/vulkan/libvulkan.so.1: full

My best guess here is there's something bad going on with the graphic card. Something I am seemingly the only one to exprerience as I couldn't find any relevant result on internet. I must mention here that I've already tried to run several AVDs in multiple API versions, both software and hardware rendered graphics and I always get the same result.

My system configuration is

AMD Ryzen 9
Nvidia GeForce RTX 2070 using the Nouveau drivers
kernel 5.11.

ANSWER

Answered 2021-Jun-07 at 13:47

If anyone ever stumbles upon this question facing the same issue than me, that was solved by getting rid of the Nouveau drivers and using Nvidia's proprietary drivers. A handful of other disturbing bugs on my computer were solved by doing just that.

I really don't understand why some Linux distribution still strongly advise to use the Nouveau drivers over Nvidia'as when they have a such a really poor support of the GPUs...

For me when I have this problem I have just updated the ANDROID EMULATOR from Android Studio. Sometimes the problem creates due to the AVD manager as well. Follow these steps if upgrading of Emulator not works:-

Go to: Tools > Android > AVD Manager Press the edit (pencil) icon next to your AVD Change Graphics to Software.

To set the ANDROID_HOME path:

To fix it go to Android Studio settings, find the proper Android SDK location, update the environment variable and restart Android Studio / your PC.

I think this will help you and your emulator works. I have got the same thing and for me it works.

NGINX Proxy not working with HTTP/2 and gRPC

Asked 2021-Apr-15 at 20:10

I am trying to use NGINX as an "API Gateway" into my gRPC services - all within a Kubernetes Cluster. A Typescript React App is just making calls via the grpc-web module to an Envoy proxy, then to the API NGINX Proxy. (I have tested that end of the stack - and I'm 100% sure that envoy works fine).

NOTE: I may be making a mistake NOT using TLS with the Envoy Proxy (Which is the 'client' to NGINX) - so please comment if that's the mistake I'm making

For this to work with my gRPC endpoints, I need to enable HTTP/2 proxying (this is required for gRPC to work - it must be over HTTP/2). And so, following the official NGINX Documentation which is here: https://www.nginx.com/blog/nginx-1-13-10-grpc/ , my nginx.conf file looks like:
