Public bug reported: In the upstream Kubernetes project Cluster API, specifically the Cluster API AWS Provider, it will download a file securely from AWS Secrets Manager in the cloud-init script, save that file to a well known location, and then restart the cloud-init service through systemd. After the cloud-init script is restarted, it will resolve the secrets file (that had previously not been there) and execute its commands.
This worked fine on versions of cloud-init up until 19.4-33-gbb4131a2-0ubuntu1~18.04.1. Once upgrading to 20.2-45-g5f7825e2-0ubuntu1~18.04.1 the secrets file is never resolved again. Some other information: - cloud-init is definitely successfully running twice based on systemd and cloud-init-output. - The /var/lib/cloud/instance/user-data.txt does show the reference to the well-known file at /etc/secret-userdata.txt - The "resolved" version of user-data at /var/lib/cloud/instance/user-data.txt.i does not include the resolved file. Deleting this file and then restarted cloud-init does not solve the problem, as the file resolves again without it. Is there another command that is now required if you plan on restarting cloud-init for another execution where files are now present that were previously not? 1. Cloud Provider: AWS 2.
