Deploy your Go app onto Azure App Services (Websites) in ease

Try it:

             Click this link, you will deploy a sample Go web app onto your Azure subscription

Details:

Azure App Services now supports Go 1.4.2 with continues deployment. Once continues deployment is setup, every time you push code to your continues deployment branch, a new deployment will be trigger.

if you read the deployment log detaily, you will notice that Azure will create a Go workspace in temp folder, then copy your code to src\azureapp, build against azureapp folder and produce an "azureapp.exe".

Last, it generate a web.config and use HttpPlatformHandler to run your Go app.

Restriction:

• Have to place main package at the root of your app
• Currently only support Go 1.4.2, no able to select a specific Go version yet

Sample Go app:

Running Go web app on Azure App Services (Websites) with custom deployment script

Short version:

Perform a continues deployment with code from this repo to your Azure Website. Once deploy, you should be able to see below result, a perfect test web app that use Go "net/http" package, Gin and Martini all together.

Behind the scenes:

The core is to understand GoDeploy.cmd script from repo, below are the key concepts:

To run Go app:
     Create a web.config as below. If you build your go app (exe file), all you need is upload your exe file and update web.config file to reference to it.

To build:

GOROOT:
    There is no GOROOT environment variable yet, but the binary is reside in "D:\Program Files\Go\1.4.2". define your own GOROOT and point to it

Build Script:

•     Create workspace and config GOPATH point to it

              workspace:
                    {folder}/src
                    {folder}/bin
                    {folder}/pkg

    ECHO creating %GOPATH%\bin
    MKDIR "%GOPATH%\bin"
    ECHO creating %GOPATH%\pkg
    MKDIR "%GOPATH%\pkg"
    ECHO creating %GOPATH%\src
    MKDIR "%GOPATH%\src"

• Create app folder under "{folder}/src", and copy source code into it

ECHO creating %GOAZUREAPP%
MKDIR %GOAZUREAPP%

ECHO copying sourc code to %GOAZUREAPP%
CP gotry.go %GOAZUREAPP%

• Resolve dependencies and build

ECHO Resolving dependencies
CD "%GOPATH%\src"
%GOEXE% get %FOLDERNAME%

ECHO Building ...
%GOEXE% build -o %WEBROOT_PATH%\%FOLDERNAME%.exe %FOLDERNAME%
