QUESTION
We've an application and API, running on kubernetes on Azure, using an nginx-ingress and cert-manager which automatically creates letsencrypt certificates. The connection to the application/API is encrypted with TLS1.3.
From an older application, running on a Win 2012 server, we want to retrieve data from the API (on k8s). This isn't successful, since TLS1.3 isn't supported on that server.
I'd like to set the minimum version of TLS to 1.2 on kubernetes. How can I achieve that?
I've read, that with kubelet, the tls-min-version can be configured, but I don't know how to apply this.
Note: we use az aks create to create the k8s clusters.
ANSWER
Answered 2022-Feb-17 at 12:11As your win server connects to the application on K8s you have to set the version of TLS on the Nginx ingress level.
Nginx ingress & cert-manager is point where you server connects and access API so you just have to update the TLS version of Nginx.
You can do it by changing the config map for Nginx ingress controller. Also, you might need to update the certificate also, there could be a chance by default Let's encrypt(CA) providing the default TLS 1.3.
So after enabling TLS 1.2 for Nginx you might need to re-generate the cert-manager secret(certificate).
Configmap Nginx ingress controller

I tried to get html using Python requests, but it redirects to the "Request Rejected" page instead of getting requiring site html. Although I get the correct response url (https://www.digikey.com/en/products/result?s=N4IgTCBcDaIC4FsDOBmMAGAZmAHOnADgF4CGIAugL5A ) I can't get the required html. Status code is 200.

QUESTION
My project w/c uses google-api-dotnet-client need to be upgrade from .Net Framework 4.5 to 4.8 in order to utilize TLS1.3. Is there a version of google-api-dotnet-client that is compatible w/ .Net Framework 4.8?
...ANSWER
Answered 2022-Jan-20 at 08:40The Google api .net client library supports 4.5+ so yes it supports .net framework 4.8 just keep an eye on the EOL for that version of .net framework at some point support for EOL versions is removed.
Even if it does not longer support it you should be able to use an outdate package on Nuget those packages should still work unless there is some major change within the api you are using, which doesnt happen often.
QUESTION
I'm using a Microservice architecture, where one service calls multiple services at a time with servers on nodejs
I was planning to use HTTP2 for API calls from one service to another, as it makes use of just one TCP connection with header compression.
However, HTTP2 needs TLS support, which implies a TLS handshake for every API call made by service to others, adding overhead roundtrips.
Although TLS1.3 takes only one round trip, still it adds up some extra overhead time.
My question is, Is it a good idea to use HTTP2 in the first place for API calls from one service to another, or it's better to continue with HTTP1.1
...ANSWER
Answered 2022-Jan-13 at 14:54HTTP2 most likely won't be more performant than ordinary HTTP1.1. It's only faster when you compare them in the context of HTTPS and parallel requests. HTTP2 allows to re-use the same TLS handshake, as well as use the same connection for multiple parallel requests (multiplex).
This is the reason you wouldn't set up HTTP2 between nginx and your app server - as you usually don't need TLS between them. So unless a) you need a secure connection between your services and b) you're planning to issue parallel requests - it doesn't seem to make sense to use HTTP2 for service-to-service communication.
PS: also read the answer by @sbordet - there seem to be use cases when HTTP2 can be beneficial even without TLS.
QUESTION
This app has been running without issue for over a year through multiple updates to both the Node application as well as the Postgres database. Last night an automated Postgres maintenance was run by Heroku, but we never got the all-clear. This morning we discovered that every http request has been returning an error since the maintenance began.

Answered 2021-Oct-19 at 17:39I eventually received a response from Heroku support telling me to run heroku ps:stop web.1 -a *** because stop causes the dyno to be replaced on a new host. I had restarted the app many times throughout the day, but that apparently doesn't trigger the reprovisioning.

I am trying to do a full-async download attempt.
The download works fine so far.
Using std::fs::File it works fine but I wanted to try tokios File to make the code fully async.
If I just download the file and let the data vanish, it works. But when I use tokio::fs::File to write async the data to disk, the download gets stuck at random locations. Sometimes at 1.1MB, mostly at ~1.6MB. Total is ~9MB.
My test URL is https://github.com/Kitware/CMake/releases/download/v3.20.5/cmake-3.20.5.tar.gz
The last output I get is the debug!("Received...") line.
The nearly complete output is:
...ANSWER
Answered 2021-Jul-10 at 08:11Thanks to @HHK in the comments above.
He recommended to build a minimal, reproducible example. While doing that, the example worked fine.
So I iteratively added the code from the original project around it.
The last step I added was a relic I did not remove when making the project async and learning about async.
I had a futures::block_on call within an async function calling an async function which resulted in blocking the whole program randomly.
So I should have made a full working piece of code before posting which would have lead me to the original problem an saved me a lot of headache.

Install tls1.3
You can use tls1.3 like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
