vNext MVC image gets killed/stopped after 3-4 seconds of working

[wisien92]

Hi,

I have successfully installed docker on Linux VM and started sample from git.

Now I want to run my procject. So I created image (which was built successfully) using command:

docker build -t versaweb .

And when I start it with command:

docker run -t -d -p 80:5004 versaweb

and when cheking using docker ps it is running but when 3 or 4 second of up time passes i check again with docker ps and it's gone. When I run project on windows machine it works flawlessly - so i belive i have something wron in project.json or in docker.

Here is my project.json:

{
"version": "1.0.0-*",
"bundleExclude": "*.cmd",
"webroot": "wwwroot",
"dependencies": {
    "EntityFramework.SqlServer": "7.0.0-beta3",
    "EntityFramework.InMemory": "7.0.0-beta3", // For Mono.
    "Kestrel": "1.0.0-beta3",
    "Microsoft.AspNet.Diagnostics": "1.0.0-beta3",
    "Microsoft.AspNet.Diagnostics.Entity": "7.0.0-beta3",
    "Microsoft.AspNet.Identity.EntityFramework": "3.0.0-beta3",
    "Microsoft.AspNet.Mvc": "6.0.0-beta3",
    "Microsoft.AspNet.Security.OpenIdConnect": "1.0.0-beta3",
    "Microsoft.AspNet.Server.IIS": "1.0.0-beta3",
    "Microsoft.AspNet.Server.WebListener": "1.0.0-beta3",
    "Microsoft.AspNet.SignalR.Server": "3.0.0-beta3",
    "Microsoft.AspNet.StaticFiles": "1.0.0-beta3",
    "Microsoft.AspNet.Session": "1.0.0-beta3",

    "Microsoft.Framework.ConfigurationModel.Json": "1.0.0-beta3",
    "Microsoft.Framework.Logging.Console": "1.0.0-beta3"
},
"commands": {
    "web": "Microsoft.AspNet.Hosting --server Microsoft.AspNet.Server.WebListener --server.urls http://localhost:5001",
    "kestrel": "Microsoft.AspNet.Hosting --server Kestrel --server.urls http://localhost:5004"

},
"frameworks": {
    "aspnet50": {
        "dependencies": {
            "Utilities": "1.0.0-*"
        }
    }
}
}

Utilities is a ASP.Net 5 Class Library.
And here is my Dockerfile :

FROM microsoft/aspnet
COPY . /app
WORKDIR /app
RUN ["kpm", "restore"]

EXPOSE 5004
ENTRYPOINT ["k", "kestrel"]

I have heared that with linux docker it is possible that it only accept aspnetcore50 freamework - if that's the case is there a way to use SSL streams and Timers? If someone who has experience with this could help me I would really appreciate this :)

I noticed that running docker with:

docker run -i -p 80:5004 versaweb

gives me errors (saying that classes from my class library doesn't exist) - what are the differences between those 2 calls?

@wisien92 those command arguments are described here: https://docs.docker.com/reference/commandline/cli/#run

[wisien92]

ok so by running without -d I can see why the image is closed -> the reason is my class library, now I wander how do I properly add the library to project ?

[wisien92]

I have removed ClassLibrary from project and it started. Can anyone tell me why is that?

@muratg not a Docker issue. This is known for a very long time.

aspnet/Hosting#59
aspnet/Hosting#140
aspnet/Hosting#129
aspnet/KestrelHttpServer#56

@wisien92 to unblock yourself try making your entrypoint:

ENTRYPOINT sleep 99999999999 | k kestrel

Oh, this issue. /cc: @victorhurdugaci

I have a PR that will allow you to configure how the server stops. aspnet/Hosting#253

[victorhurdugaci]

This should be fixed as part of aspnet/Hosting#140
