JsReport Issue after deployed on Openshift

Used Jsreport for converting htmltopdf in .Net Core when deployed on openshift getting Below Error

You can try to disable keepAlive, but not sure if that helps.

new LocalReporting().UseBinary().AsUtility().KeepAlive(false)

I'm not very familiar with OpenShist. How do you deploy there? To a VM you have full control over? Or you use some kind of PaaS where you deploy a docker container? If yes, does that container work outside OpenShift?
Does the platform have some restrictions on running child programs, like headless chrome?

[AyagoleSneha]

-We build docker image using docker file from .net core 6.0 then the same docker image is deployed to Openshift platform
container .Container does not work out side openshift platform.
-To use external services we need to define in ocp policy.
-Can you help use to understand how internally jsreport works to convert html to pdf.
-Jsreport is using any external resources that we need to whitelist.
-We have seen exceptions where logs are using localhost:5488.

-Used Below code
var rs = new LocalReporting()
.KillRunningJsReportProcesses()
.UseBinary(RuntimeInformation.IsOSPlatform(OSPlatform.Windows) ? JsReportBinary.GetBinary() : jsreport.Binary.Linux.JsReportBinary.GetBinary())
.Configure(cfg => cfg.AllowedLocalFilesAccess().FileSystemStore().BaseUrlAsWorkingDirectory())
.AsUtility()
.Create();
var tedPdf = await rs.RenderAsync(new RenderRequest
{
Template = new Template
{
Recipe = Recipe.ChromePdf,
Engine = Engine.None,
Content = "Hello",
Chrome = new Chrome
{
MarginTop = "10",
MarginBottom = "10",
MarginLeft = "50",
MarginRight = "50"
}
}
});

-Docker File
DockerFile.txt

Let me know if you any more information.

Any Update ?

[pofider]

The .net jsreport direct integration works the following.
The jsreport.Binary assembly has in its manifest compiled jsreport.exe binary.
When the jsreport.Local starts rendering, it takes the jsreport.exe and copy it to the temp directory.
Then the jsreport.exe is used with command line arguments like described here https://jsreport.net/learn/single-file-executable
The jsreport.exe during the first call extracts all needed resources to the temp directory. This includes chrome.exe.

Now there are two options.

1. You use default keep alive optimization
   In this case the jsreport.exe is called with --keep-alive flag which instructs to spawn jsreport process on background and communicate with it over 5488 protocol. For spawning a background process another WinRun.exe executable is used as wrapper. You can find it in the temp directory as well. So....
   You call in c# reportingService.Render and this makes the call

jsreport.exe --keep-alive render

This spawns a new WinRun.exe process that spawns another jsreport.exe. The background jsreport.exe is contacted using http:5488. In case you use chrome-pdf recipe the background process starts Chrome.exe which does the html -> pdf conversion. When report is done, the calling jsreport.exe is closed but the background processes jsreport.exe, WinRun.exe and Chrome.exe keeps running.
Note the WinRun.exe is used only on Windows.

2. You disable keep alive optimization
   In this case jsreport.exe render command is called which creates Chrome.exe process eventually. After printing is done, everything is exitted.

I am not sure if this helps. Unfortunately, I am too busy to play with OpenShift at this moment.
In general, my recommendation is to use jsreport.Local primarily during development, prototyping or when you really require just one service to be deployed. Otherwise, run the jsreport as a separate service. You can find here how simple it is
