title: what's the meaning of the empty value {} kubernetes helm chart yaml file?
body: <p>What's the meaning of the empty value <code>{}</code> in a Helm chart YAML file?</p>
  <p>In some Helm charts I see some <code>values.yaml</code> or <code>override_values.yaml</code> files, there are empty values <code>{}</code> in them.
  For example</p>
  <pre class="lang-yaml prettyprint-override"><code>containerSecurityContext: {}
  podSecurityContext: {}
  </code></pre>
  <p>What is the purpose of those <code>{}</code> values in the YAML file? Does it mean to use default value or parent folder YAML file value or something else?</p>
