  <p>I´m triying the following:</p>
  <pre><code>root@oc-jump-pod:/# oc patch deploy push-engine --type='json' -p='{&quot;spec&quot;:{&quot;template&quot;:{&quot;metadata&quot;:{&quot;spec&quot;:{&quot;containers&quot;:{&quot;image&quot;:&quot;registry.sdi.
  dev.weu.azure.paas.cloudcenter.corp/test-dev/test:0.0.1&quot;}}}}}}'
  Error from server (BadRequest): json: cannot unmarshal object into Go value of type jsonpatch.Patch
  </code></pre>
  <p>and this to get the value</p>
  <pre><code>root@oc-jump-pod:/# oc get deploy push-engine -o=jsonpath='{..image}'
  registry.sdi.dev.weu.azure.paas.cloudcenter.corp/test-dev/test-java:0.0.2
  </code></pre>
  <p>I need do that, to change the tag of the image from 0.0.2 to 0.0.1 (or others). Probably I don´t understand oc patch yet, actually I do the change manually on the oc console. But this method, is rude and not follow the CI/CD.</p>
