IBM Cloud Code Engine fails to build for private repo

I'm using IBM Cloud Code Engine to build the source code from a private git repo. I have tried many times, and the buildrun always failed. Following are the steps I have done.

  1. Add my public key (/root/.ssh/id_rsa.pub) to my private repo as a deploy key

  2. Use IBM Cloud Code Engine CLI to create repo access credential ibmcloud ce repo create --name ibmgithub --key-path /root/.ssh/id_rsa --host github.ibm.com

  3. Use IBM Cloud Code Engine CLI to create a build and then submit a build run ibmcloud ce build create --name minion --image us.icr.io/mynamespace/myimg --rs ce-default-icr-us-south --git-repo-secret ibmgithub --source https://github.ibm.com/myaccount/myrepo --strategy dockerfile --size medium

  4. The build run always fails

  1. I doubt the build run failed to fetch the source code from my private repo. And I checked on the repo UI, it shows the deploy key Never used.

Can anyone shed some light on it ? Thanks.

Solution

  • Since you're using an ssh key, make sure the URL to your git repo starts with git@ instead of https://. So it should be git@github.ibm.com/myaccount/myrepo in your case.

    For further issues with failing builds, you can check the related troubleshooting buildruns section in the Code Engine docs.
