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.

ASP.NET Core app deployed to Pivotal Cloud Foundry

First we need to make some changes to our project

1. Open "dotnet-core-mvc.csproj" and add "RuntimeIdentifiers" inside the "PropertyGroup" tag


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
