Fluentbit with Tomcat logs

You didn't specify 👀 how you deployed fluent-bit.

But yes you can run it as a different user specifying a SecurityContext in Kubernetes.

For example:

apiVersion: apps/v1kind: DaemonSetmetadata:  name: fluent-bit  namespace: logging  labels:    k8s-app: fluent-bit-logging    version: v1    kubernetes.io/cluster-service: "true"spec:  selector:    matchLabels:      k8s-app: fluent-bit-logging  template:    metadata:      labels:        k8s-app: fluent-bit-logging        version: v1        kubernetes.io/cluster-service: "true"      annotations:        prometheus.io/scrape: "true"        prometheus.io/port: "2020"        prometheus.io/path: /api/v1/metrics/prometheus    spec:      securityContext:        runAsUser: 1000 👈 user id that you want to run the containers in the pod as      containers:      - name: fluent-bit        image: fluent/fluent-bit:1.3.11        imagePullPolicy: Always        ports:          - containerPort: 2020        volumeMounts:        - name: varlog          mountPath: /var/log        - name: varlibdockercontainers          mountPath: /var/lib/docker/containers          readOnly: true        - name: fluent-bit-config          mountPath: /fluent-bit/etc/        - name: mnt          mountPath: /mnt          readOnly: true...

thanks for all the tips, I tried all of them, and it works, but unfortunately, on our deployments it does not as we have some custom users.

What was needed to be done is to set the UMASK as env variable with a value of "111" which would change permissions of the log files so they can be picked up by fluent-bit.
