Error rendering report on CentOs 7

[Emiliano Savi]

Wel, it seem I need to study more in deep net core ... as many other things :D

After your suggestions now I receive:
One or more errors occurred. (Permission denied) - at System.Threading.Tasks.Task`1.GetResultCore(Boolean waitCompletionNotification)
The code that generate this is :
var CustomRenderRequest = new RenderRequest()
{
Template = new Template()
{
Content = email.Attachment,
Engine = Engine.None,
Recipe = Recipe.PhantomPdf
}
};
var customReport = rs.RenderAsync(CustomRenderRequest).Result;

My question is: how can it render without a screen ?

PS: if I use this raw code I can create the pdf
ar p = new Process();
p.StartInfo = new ProcessStartInfo()
{
FileName = "google-chrome",
Arguments = "--headless --disable-gpu --print-to-pdf="/tmp/zkmf/zkmf_receipt.pdf" /tmp/zkmf/zkmf_receipt.html"
};
p.Start();
p.WaitForExit();

Same problem on Ubuntu server.

Hm. Not sure how to proceed with this. It would help if you would prepare for me a way how to replicate this. Like a minimal project that I can try to run on ubuntu.
However I guess there is a problem rather with server set up. The best would be if you would prepare a dockerfile i can try to use and replicate the issue.

[Emiliano Savi]

Uhm ... how can I create a docker file ? I can google a bit, but if u have short instructions I'll do my best to create it.

[jan_blaha]

Give me a moment, I will give you some hints.

[jan_blaha]

I prepared repository showing how can jsreport run on ubuntu docker container. You can open it in VS and just hit F5 to see it working,
https://github.com/pofider/jsreport-net-core-docker

You will be mainly interested in the dockerfile which describe the steps how is .net core initialized on the fresh ubuntu and how it starts the .net core app.

[Emiliano Savi]

Well, just installed Docker ... How to run on container from VS 2017 Pro ?

But my question is: how can I 100% reproduce my AWS server with Docker, if I really can ?

[jan_blaha]

Well, just installed Docker ... How to run on container from VS 2017 Pro ?

You should be able just to F5 my example solution. Here are the docs to vs tools for docker

But my question is: how can I 100% reproduce my AWS server with Docker, if I really can ?

There are usually some community docker images which tries to reflect the AWS linux images. However I have no experience with that.
What kind of AWS service you use? Simple EC2? Which image? Did you try to run as root?

[Emiliano Savi]

If I hit F5 it runs as a standard console app on my machine.
Did u forget some files, maybe ? I can't find no docker-compose.yml, for example

[jan_blaha]

My apologize ... Now is the repo full.

[Emiliano Savi]

So, on my Win10 Pro I installed Docker, Linux containers mode is on, a small Hyper-V VM is running ...
I open your last repository, hit F5 but if I print in which OS is running the app I receive Windows.
How do I know if I'm running in a container ?

Ok, a few steps ahead:

dotnet publish --> ok

docker build --> ko
Step 10/11 : COPY ${source:-obj/Docker/publish} .
docker : COPY failed: stat /var/lib/docker/tmp/docker-builder957303330/obj/Docker/publish: no such file or directory
At line:1 char:1

• docker build dockernetcoretest

•   + CategoryInfo          : NotSpecified: (COPY failed: st...le or directory:String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError

[jan_blaha]

Not sure if this is the issue. But my docker settings include the shared drive.

[Emiliano Savi]

Mine too.
I'll inspect this issue.

[jan_blaha]

here they recommend to clear the .dockerignore file.

[Emiliano Savi]

So, if i publish explicitly in /Docker/publish the doker build process terminate correctly ?
Now ? Where is my app ? Can I debug it on Linux ?
Too many doubts :-)

[jan_blaha]

I'm not sure I get what you ask for. I simply run it as on the following gif. Thank you for your patience.

[Emiliano Savi]

This is exactly what I want to do, but I always ges Windows as OS.
Did you run some manual command (dotnet, docker, ...) or simply hit F5 ?
To start the image I run some manual commands

[jan_blaha]

Make sure the startup project is the docker-compose one.
I don't run any special command, just f5 or click on the Run docker arrow.

[Emiliano Savi]

Holy crap! I set the console as starting prj!!!
Let's try ... TY
