filer-sidecar-injector

This is forked off of the repo kube-sidecar-injector and was a repo used for a tutorial at Medium to create a Kubernetes MutatingAdmissionWebhook that injects a nginx sidecar container into pod prior to persistence of the object.

Forked for Filer usage

Specifically for use with Filers.

Gotcha's

Make sure that the namespace you want injected has the filer-sidecar-injection: enabled label on it. This will then add the sidecar to pods that have the notebook-name label present. Ensure that there is a secret whose name contains filer-conn-secret in the namespace with the following populated;

S3_ACCESS
S3_BUCKET
S3_URL
S3_SECRET

Is there the `NB_PREFIX environment variable present on the user container? We use the existence of the value to determine where to put the volume mount.
