In kubernetes I run external secrets, which is nice. I store The secrets in key value or file format in AWS Secrets Manager, which gets synchronized to the cluster into a secret. From there it gets mounted into the running pod via the envFrom or volume mount method.

External secrets are great, especially if your app can read them directly from k8s and avoid ever having them mounted as a volume (or in env var).

If your app can’t interface directly w/k8s, but it can read secrets from a file, you can use a small init program to fetch the k8s secret and write it to a named pipe. This is advantageous compared to mounting as a volume, because the pipe disappears after both ends close their connection to it.
