Image automation controller gives the following error log:

I am using gitlab token to provision the flux deployment. The command that I use as follows:

export GITLAB_TOKEN="xxxx"

flux bootstrap gitlab \
    --owner=xxx/xxx \
    --repository="xxx"  \
    --branch=master \
    --log-level debug \
    --hostname="gitlab.com" \
    --path="xxx/xxx" \
    --components-extra=image-reflector-controller,image-automation-controller

Flux version:

flux version 0.7.2

With the error log that I receive from image-automation-controller, I do not see useful information to troubleshoot this issue.

Hello,

I think this issue is resolved on my end. I realized that I forget to add --token-auth flag when I bootstrap the flux. A proper error message would still be helpful though :). I am closing this issue now.

For some folks that coming here and rely on Deploy key instead of personal GITLAB_TOKEN.

In order for ImageUpdateAutomation to work without bootstrap using --token-auth we need to enable write access to Deploy key that flux use
