I'm trying to configure a daemonset to run on the global pid namespace resulting the ability to see other processes in the host, including the containers' processes.
I couldn't find an option to achieve this.
In general, what I'm looking for is close to the sidecar container shareProcessNamespace attribute only on the host level.
There is an attribute that allows this - hostPID: true
So the yaml file should looks something like that:
apiVersion: apps/v1
kind: DaemonSet
metadata:
name: busybox
spec:
selector:
matchLabels:
name: busybox
template:
metadata:
labels:
name: busybox
spec:
hostPID: true
containers:
- name: busybox
image: busybox
command: [ "sh", "-c", "sleep 1h" ]More info in:
