title: Pattern matching with gcloud --filter
body: <p>I want to get a list of tags matching a certain pattern and to do that I have been using the command:</p>
  
  <p><code>gcloud container images list-tags gcr.io/project/reposiory --format="json" --filter="tags:*_master"</code></p>
  
  <p>but I'm getting this warning:</p>
  
  <p><code>WARNING: --filter : operator evaluation is changing for consistency across Google APIs.  tags:*_master currently matches but will not match in the near future.  Run `gcloud topic filters` for details.</code></p>
  
  <p>I've searched around but can't find how I'm supposed to do this going forwards. Does anyone know how I can match a pattern in this way i.e. all tags that end with "_master"?</p>
