The authenticator binary uses glog which requires write access to the filesystem under /tmp On the scratch image /tmp doesnt exist which caused a crash loop: ``` time="2020-02-14T02:06:00Z" level=info msg="creating event broadcaster" time="2020-02-14T02:06:00Z" level=info msg="setting up event handlers" W0214 02:06:00.358119 1 client_config.go:539] Neither --kubeconfig nor --master was specified. Using the inClusterConfig. This might not work. log: exiting because of error: log: cannot create log: open /tmp/aws-iam-authenticator.ip-X-X-X-X.aws-iam-authenticator.log.WARNING.20200214-020600.1: no such file or directory ``` Switching to debian-stretch fixed the issue although it could really be any of the other images in the release [0] [0] https://github.com/kubernetes-sigs/aws-iam-authenticator/releases/tag/v0.5.0
