how to override container **Entrypoint** and **Cmd**

[vermapraveen]

I am trying to override Entrypoint and Cmd of given docker image. While doing so: on CLI it works and container starts, I can see app logs, though when I try to construct in code using TestContainer, I see error. I am sure I am constructing it wrong,

can someone suggest what I am doing wrong

Works OK

docker run 
--env ENVIRONMENT=sit 
--entrypoint /bin/sh harbor.myrepo.com/project1/events.handler:11684730-ae8b71bf 
-c './integrationFolder/EventIntegration'

But for equivalent Code

 private readonly TestcontainersContainer _eventHandlerContainer = 
        new TestcontainersBuilder<TestcontainersContainer>()
	    .WithEntrypoint("/bin/sh")
	    .WithImage("harbor.myrepo.com/project1/events.handler:11684730-ae8b71bf")
	    .WithCommand("./integrationFolder/EventIntegration")
	    .WithEnvironment("ENVIRONMENT", "sit")
	    .Build();

I see below error

Docker.DotNet.DockerApiException : Docker API responded with status code=BadRequest, response={
"message":"failed to create shim task: OCI runtime create failed: runc create failed
: unable to start container process: exec: \"./.csproj\": stat ./.csproj
: no such file or directory: unknown"}

docker inspect gives below config in container

{
  "Config": {
    "Cmd": null,
    "WorkingDir": "/home/someuser",
    "Entrypoint": [
      "./.csproj"
    ]
  }
}

That's not equivalent. You use -c './integrationFolder/EventIntegration' as docker run argument (even if I don't understand how that results in the shown docker inspect result). Try:

.WithEntrypoint("/bin/sh", "-c")
.WithCommand("./integrationFolder/EventIntegration")
