title: Kubernetes security context runAsUser
body: <p>I have multiple containers and want to run all the containers as a non-root user, I know adding securityContext will help me, but do I need to add securityContext in all the containers or adding it in specs level will help?</p>
  
  <pre><code>spec:
    template:
      metadata: Test image
  
    spec:
      securityContext:
        runAsUser: 1000
        fsGroup: 1000
      containers:
      -name: container-1
       securityContext:
         allowPrivilegeEscalation: false
      -name: container-2
       securityContext:
         allowPrivilegeEscalation: false
  </code></pre>
  
  <p>The question is, <code>runAsUser</code> is applicable to all the container i.e., all the containers (container-1, container-2) will run as user 1000 or I need to specify securityContext in all the container?</p>
