kandi X-RAY | endpoints Summary

endpoints is a Go library typically used in Networking, Load Balancing applications. endpoints has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Package endpoints provides an implementation of a client-side load balancer that distributes client request across a collection of Kubernetes endpoints using a basic Round-robin algorithm. The endpoints load balancer does not operate in the data path and only manages a list of backends based on services defined in a Kubernetes cluster.

            How to get token from API with Python?

            ANSWER

            Answered 2021-Jun-12 at 17:16

            First note that a token must be obtained from the server ! A token is required to make some API calls due to security concerns. There are usually at least two types of tokens:

            • Access token: You use it to make API calls (as in the Authorization header above). But this token usually expires after a short period of time.
            • Refresh token: Use this token to refresh the access token after it has expired.

            You should use requests-oauthlib in addition with requests.
            https://pypi.org/project/requests-oauthlib/
            But first, read the available token acquisition workflows:
            https://requests-oauthlib.readthedocs.io/en/latest/oauth2_workflow.html#available-workflows
            and choose the right workflow that suits your purposes. (The most frequently used is Web App workflow)
            Then, implement the workflow in your code to obtain the token. Once a valid token is obtained you can use it to make various API calls.

            As a side note: be sure to refresh token if required.

            Installing Quickstart UI for IdentityServer4
            Asked 2021-Jun-15 at 17:53

            I created an empty asp.net core web application (dotnet new web -n ) and went to the github for IdentityServer4.Quickstart.UI and was followed the instructions to add the quickstart UI. I first did the powershell cmd iex ((New-Object System.Net.WebClient).DownloadString('https://raw.githubusercontent.com/IdentityServer/IdentityServer4.Quickstart.UI/main/getmain.ps1')) to download the files and run the application but it keeps telling me Index not found but the file is inside of the Views folder. So I then deleted all those files it downloaded from the project and installed it using its templates by running the cmds dotnet new -i identityserver4.templates then dotnet new is4ui --force which downloaded those files again onto my project. However, it keeps telling me the same message.

            I noticed that under the Quickstart folder, contains a folder named Home which has the HomeController.cs and the namespace is as IdentityServerHost.Quickstart.UI... do I need to change that namespace to match my solution i.e. ids.Quickstart.Home?

            What is causing this to display that error when infact there is the Index.cshtml file inside of the Views folder?**

            How do you do GRPC authentication in an istio mTLS setup?
            Asked 2021-Jun-15 at 14:41

            I have bunch of GRPC microservices and they are using self signed certs. I add authentication info to the GRPC channel which is then used to identify endpoints and provide right services.

            Now I want migrate to Istio mTLS.

            In phase one, I got Istio to BYPASS all GRPC connections and my services works as it is now.

            In Phase two, I want to hand off TLS to Istio, but I am stuck on how to pass the authentication information to GRPC?

            How do you handle auth in Istio mTLS setup?

            GRPC can support other authentication mechanisms Has anyone used this to inject Istio auth info to GRPC? any other suggestions on how you implemented this in your setup

            I am using go-lang just in case if this can be useful to provide any additional information.

            One way of doing this is using grpc.WithInsecure(), this way you don't have to add certificates to your services, since istio-proxy containers in your pods will TLS terminate any incoming connections.

            How in WebFlux to stop publisher when request is aborted by client?
            Asked 2021-Jun-15 at 09:06

            SpringBoot v2.5.1

            There is an endpoint requesting a long running process result and it is created somehow
            (for simplicity it is Mono.fromCallable( ... long running ... ).

            Client make a request and triggers the publisher to do the work, but after several seconds client aborts the request (i.e. connection is lost). And the process still continues to utilize resources for computation of a result to throw away.

            What is a mechanism of notifying Project Reactor's event loop about unnecessary work in progress that should be cancelled?

            ...

            ANSWER

            Answered 2021-Jun-15 at 09:06

            fromCallable doesn't shield you from blocking computation inside the Callable, which your example demonstrates.

            The primary mean of cancellation in Reactive Streams is the cancel() signal propagated from downstream via the Subscription.

            Even with that, the fundamental requirement of avoiding blocking code inside reactive code still holds, because if the operators are simple enough (ie. synchronous), a blocking step could even prevent the propagation of the cancel() signal...

            A way to adapt non-reactive code while still getting notified about cancellation is Mono.create: it exposes a MonoSink (via a Consumer) which can be used to push elements to downstream, and at the same time it has a onCancel handler.

            You would need to rewrite your code to eg. check an AtomicBoolean on each iteration of the loop, and have that AtomicBoolean flipped in the sink's onCancel handler:

            Registration of dynamic websocket at application initialization time and at runtime has different endpoints exposed
            Asked 2021-Jun-14 at 21:32

            I am trying to register websocket dynamically.For instance, i have registered '/sampleEndpoint' at runtime so ServerWebSocketContainer will register it and start publishing data on that endpoint. But now if i do the same process during application initialization time in PostConstruct than i am unable to connect to '/sampleEndpoint' but have to append '/websocket' at the end so url become '/sampleEndpoint/websocket' when connecting from client side. Why we are getting different endpoints at different situations?

            I have attached github url to the code.

            Well, that's how that SockJS option works: https://docs.spring.io/spring-framework/docs/current/reference/html/web.html#websocket-fallback.

            If you client is not SockJS, then you have to add that /websocket sub-path.

            Not sure though why it doesn't work for dynamically registered endpoints...

            In the case of @PostConstruct it is not dynamic: we still do the stuff within configuration phase of the application context, so it is able to add our endpoint into a static HandlerMapping. The dynamic nature is applied a bit later, when all the @PostConstruct have done their logic. You don't need to start that flow registration manually though since the auto-startup phase has not passed yet withing @PostConstruct handling.

            Re. IntegrationDynamicWebSocketHandlerMapping: it sounds more like a bug and I need to investigate more. I guess you still use there that SockJS option and it has to be applied for dynamic endpoint as well.

            Thank you for your patience! I'll investigate and fix it ASAP.

            Is probing of a Pod retried after a readiness probe fails
            Asked 2021-Jun-14 at 12:32

            readinessProbe: Indicates whether the container is ready to respond to requests. If the readiness probe fails, the endpoints controller removes the Pod's IP address from the endpoints of all Services that match the Pod. The default state of readiness before the initial delay is Failure. If a Container does not provide a readiness probe, the default state is Success

            If the readiness probe fails (and the Pod's IP address is removed from end point), what happens next? Will the Pod's readiness probe conditions be checked again? Will it check again after initial delay? Is there any chance the Pod's IP address is added to the end point again (if the Pod self healed after readiness probe fails)? Will that Pod receive traffic again incase if it's healed?
