What

Solved: #31697

In case you need to implement a sidecar pod that needs to be killed once the bootloader is completed. Example sidecar to connect to db (gcp auth proxy): Create a pod with 3 containers:

• Bootloader container
• Cloud SQL Auth Proxy container that creates a secured tunnel to communicate with managed GCP database
• Additional container that scan processes to killed Cloud SQL Auth Proxy container when bootloader container is done If you don't have this mechanism bootloader pod will still be ready, even if bootloader container is in completed state because Cloud SQL Auth Proxy container is still up and airbyte deployment process will be stuck.

How

Add shareProcessNamespace feature into the bootloader helm chart (https://kubernetes.io/docs/tasks/configure-pod-container/share-process-namespace/)
