dotnet publish - ASP.NET Core app deployed to Pivotal Cloud Foundry

I previously showed how to push a ASP .NET Core application to Pivotal Cloud Foundry by just using the source code files itself. It turns out this creates a rather large droplet and hence slows down the deployment. So here we are going to take the same demo and use "dotnet publish" to make this a lot faster. The previous post is here which is the base for this blog entry itself.

First we need to make some changes to our project

1. Open "dotnet-core-mvc.csproj" and add "RuntimeIdentifiers" inside the "PropertyGroup" tag
  
<PropertyGroup>
    <TargetFramework>netcoreapp1.0</TargetFramework>
    <RuntimeIdentifiers>osx.10.10-x64;osx.10.11-x64;ubuntu.14.04-x64;ubuntu.15.04-x64;debian.8-x64</RuntimeIdentifiers>
</PropertyGroup>



2. Perform a "dotnet restore" as shown below either form a terminal windows/prompt or from Visual Studio Code itself , this step is vital and is required

pasapicella@pas-macbook:~/pivotal/software/dotnet/dotnet-core-mvc$ dotnet restore
....

3. Now lets publish this as Release and ensure we target the correct runtime. For Cloud Foundry (CF) that will be "ubuntu.14.04-x64" and the framework version is 1.0 as we created the application using 1.0 , we could of used 1.1 here if we wanted to.

pasapicella@pas-macbook:~/pivotal/software/dotnet/dotnet-core-mvc$ dotnet publish --output ./publish --configuration Release --runtime ubuntu.14.04-x64  --framework netcoreapp1.0
Microsoft (R) Build Engine version 15.1.548.43366

  dotnet-core-mvc -> /Users/pasapicella/pivotal/software/dotnet/dotnet-core-mvc/bin/Release/netcoreapp1.0/ubuntu.14.04-x64/dotnet-core-mvc.dll

4. Finally cd into the "Publish" folder and verify there are the required DLL's as well as project files, JSON files , everything ready to run your application.

pasapicella@pas-macbook:~/pivotal/software/dotnet/dotnet-core-mvc/publish$ ls -lartF

drwxr-xr-x  212 pasapicella  staff     7208 Mar 21 08:01 ./

5. Now this time lets "cf push" using the files in the "Publish" folder and

pasapicella@pas-macbook:~/pivotal/software/dotnet/dotnet-core-mvc/publish$ cf push pas-dotnetcore-mvc-demo -b https://github.com/cloudfoundry/dotnet-core-buildpack -m 512m
