@nekomeowww fyi I tested yesterday this change with the unstable tag for the operator created after merging my PR. Everything looks good now and we are able now to define security context in pod template field to the containers to run as non root as intended with change #105

...
  podTemplate:
    spec:
      securityContext:
        fsGroup: 1000
      containers:
      - name: server
        image: ollama/ollama
        imagePullPolicy: Always
        securityContext:
          runAsNonRoot: true
          runAsUser: 1000
          runAsGroup: 1000
          allowPrivilegeEscalation: false
          capabilities:
            drop:
              - ALL
      initContainers:
      - name: ollama-image-pull
        image: curlimages/curl
        imagePullPolicy: Always
        securityContext:
          runAsNonRoot: true
          runAsUser: 1000
          runAsGroup: 1000
          allowPrivilegeEscalation: false
          capabilities:
            drop:
              - ALL
