QUESTION
For various reasons I want to be able to use a proxied data table and replaceData while client side processing is being used i.e. DT::renderDataTable(..., server = FALSE)
.
I have a shiny application/dashboard that communicates to a database and presents information to a user. The user is able to fill out a form in the application which will be added to the database and then the shiny app updates the data by making a query to the database to fetch the new information.
The application is currently being deployed via kubernetes using a LoadBalancer
with the intention to use multiple replicas to scale up the application as needed. The application is not being run through shinyproxy.
Currently, when the application is being run by a single replica (process) the application will behave perfectly fine and is able to use server=TRUE
. However when I increase the number of processes/replicas to run, the data is not able to be presented to users unless server=FALSE
is specified in renderDataTable
. For a currently unknown reason but I suspect it might be due to the sessions not being sticky to IPs
While the code is able to function fine when server = TRUE
if I want to allow multiple users to application they all cannot share a single process as the application will become very slow once multiple connections are made. As a result I likely need to use server=FALSE
so each user is able to see the data at the cost of a very important functional detail (replaceData
stops working). The product owner of the application is insistent that this behaviour remains intact as the data present is often large and requires some column sorting and paging to find a piece of information you want to look at. And when submitting a form, if I do not use replaceData
and reconstruct the table from scratch the users previous table state is lost.
So while I could tear down the datatable and regenerate it within an observeEvent

How I can specify more that one service for the nginx ingress websocket annotation?
...ANSWER
Answered 2021-Jan-20 at 15:19NGINX Ingress WebSocket support page says:
To load balance a WebSocket application with NGINX Ingress controllers, you need to add the nginx.org/websocket-services(you use nginx.ingress.kubernetes.io) annotation to your Ingress resource definition. The annotation specifies which services are websocket services. The annotation syntax is as follows:
QUESTION
long time i didn't had to write a post here. I guess i am really stuck... I built long time ago a monolithic app based on react and express that was handling a chat with socket.io. I remember i did struggle a little but at the end i make it work.
I am now reconverting the same app into microservices with kubernetes (on GKE) and after build the chat backend and the front, i just cannot make the chat work. It's seems somehow the socket.io instances are not connected. I tryed a lot of different things and i am now asking help regarding it. I will share bellow the parts of the code that are implying it.

Answered 2020-Dec-05 at 22:46I found a solution there for the people that might struggle like me...i think it's a bit of hacky but it work well.
I was observing in my front that the socket were all the time triggering under the /socket.io/.... and if you take a look at my ingress nginx that would look into my react app and return a 404 page probably.
So i forced my chat-srv to be present there on this specific endpoint with the following code:

Install socket-service
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
