Now I think there may be something wrong with the yml or the images. But how can I figure that out? Does anyone see issues with the yaml here? The images are Laradock PHP FPM and Nginx and they built fine and are publicly accessible on Docker Hub so no idea what the issue is here…
Did read
This message says that it is in a Back-off restarting failed container . This most likely means that Kubernetes started your container, then the container subsequently exited. As we all know, the Docker container should hold and keep pid 1 running or the container exits. When the container exits, Kubernetes will try to restart it. After restarting it a few times, it will declare this BackOff state. However, Kubernetes will keep on trying to restart it.

So perhaps it is the image then?
