injection causes container sequence to change

[electrical]

In my cluster I'm running Linkerd which is a service mesh. This injects a proxy container next to the main container in the same pod.
When I inject an initcontainer with this project it changes the sequence of the 2 containers inside the pod making the linkerd proxy container the 'main'/0 container.
Is this expected behaviour?

Done a bit more digging into it. It seems to be doing some sorting based on the name which I didn't expect

This is an issue btw on pods with slow starting containers.
The sidecar might be injected first in order and if it's "Ready" before the slow starting one it might cause requests to arrive to the pod even though the main container is still starting.
