You can migrate ASP.NETCore projects in F# by using the Custom Runtime and HTTP triggers
of Function Compute. You can access a function by using a browser or HTTP client tools
such as cURL.
Prerequisites
Before you begin, make sure that you have completed the following operations:
- Install Node.js 8.6.0 or later. For more information, visit Downloads.
- Install Docker. For more information, visit Docker Hub.
Note The examples in this topic apply to scenarios where Docker is installed. If you do
not want to use Docker, you must install .NET Core 3.1. For more information about
how to install .NET Core 3.1, see
dot.net.core3.1. For more information about the commands of .NET Core 3.1, see
fc-custom-demo.
Procedure
- Run the following command to clone the sample project to the on-premises machine:
git clone https://github.com/awesome-fc/fc-custom-demo
- Run the following command to go to the cloned sample project:
- Run the following command to go to the FSharp-demo directory:
- Run the following command to deploy the function:
make deploy
The following output is returned:
docker run -it -v $(pwd):/tmp mcr.microsoft.com/dotnet/core/sdk:3.1 bash -c "cd /tmp/FSharpDemo && dotnet publish -r linux-x64 -c Release --self-contained true && cd /tmp/FSharpDemo/bin/Release/netcoreapp3.1/linux-x64/publish && mv FSharpDemo bootstrap && chmod +x bootstrap"

Http Trigger will forcefully add a 'Content-Disposition: attachment' field to the response header, which cannot be overwritten
and will cause the response to be downloaded as an attachment in the browser. This issue can be avoided by using CustomDomain.

Detect 'DomainName:Auto' of custom domain 'my_domain'
Fun will reuse the temporary domain 16225220-19861144****.test.functioncompute.com, expired at 2020-04-17 10:07:00, limited by 1000 per day.

custom domain my_domain deploy success
- Run the following command to invoke the deployed function:
curl 16225220-1986114430****.test.functioncompute.com/weatherforecast
Notice
http://********-*********.test.functioncompute.com can be obtained from the output of Step 3.
- If you use the Windows operating system, you must convert the format of the bootstrap file to UNIX.
The following output is returned:
