Unable to Deploy Spring Boot Application In Openshift

I am following the below steps to run my Spring Boot app: https://github.com/debasen/springboot-demo.git in Open shift:

  1. Add Red Hat OpenJDK8 to my project.

After doing this. I am getting the following Log at Build:

As no jar is created at the time of build the deployment is failing. While the project in the sample repository https://github.com/jboss-openshift/openshift-quickstarts works fine. I tried Heroku to host my app. It works fine in Heroku. But not working in Openshift. Please tell me what am I missing.

Solution

  • The build log is not reporting an explicit error, but suggests that nothing was built actually:

    S2I source build with plain binaries detected
Copying binaries from /tmp/src to /deployments ...
... done

    As your repo "hides" the app source in a parent folder, try either specifying the contextDir (that is /, by default) to springboot-demo for your build, or move the app source to the root of your git repository.

    You can edit the build Configuration using the oc CLI by oc edit bc/<build_config_name> or do the same using the web interface by clicking the "advanced options" link when you're providing the git repo URL during deployment of the application from the catalog, or by using Actions -> Edit menu item when browsing the existing build configuration.
