Go application deployment in Bluemix fails

I am facing issues with pushing the sample Go applicaiton in Bluemix.

I will explain the steps I followed to push the applicaiton.

  1. Created D:/goapp2016 and set it to GOPATH.
  2. created src, pkg and bin folders in D:/goapp2016
  3. In src, created "myapp" folder and written a sample app.go file.
  4. Ran "go get" command inside GOPATH/src/myapp and that downloaded the libraries from Git in GOAPTH/src folder and mysql.a,native.a files in D:\goapp2016\pkg\windows_amd64\github.com\ziutek\mymysql. And myapp.exe is also created in GOPATH/bin after running go get command.
  5. Ran "godep save" command which created Godeps/Godeps.json and vendor/(dependent libraries) folder in GOPATH/src/myapp.
  6. To push the application to bluemix, I executed cf push command from GOPATH directory.

But, this is giving the below error.

Am I missing anything here?

Solution

  • The compile file for the buildpack can be seen here: https://github.com/cloudfoundry/go-buildpack/blob/master/bin/compile

    Dependency tool selection begins on line 136, as long as there is a Godeps/Godeps.json file, the buildpack should used godeps, not GB. Are you sure you are pushing from the folder than contains the Godeps folder, that in turn contains the Godeps.json file?
