  <p>If I use the api (post greeting), the response code is 500 
  "hydra:description": "cURL error 6: Could not resolve host: cache-proxy (see <a href="http://curl.haxx.se/libcurl/c/libcurl-errors.html" rel="nofollow noreferrer">http://curl.haxx.se/libcurl/c/libcurl-errors.html</a>)",
    "trace": [</p>
  
  <p>Nevertheless the entity is still inserted.</p>
  
  <p>Furthermore I tried the api-platform without docker (Apache). 
  I removed the line VARNISH_URL=<a href="http://cache-proxy" rel="nofollow noreferrer">http://cache-proxy</a> in the .env file.
  Then the return code is 500 with
  "cURL error 3:  malformed (see <a href="http://curl.haxx.se/libcurl/c/libcurl-errors.html" rel="nofollow noreferrer">http://curl.haxx.se/libcurl/c/libcurl-errors.html</a>)"</p>
  
  <p>Do you have any idea?</p>
  
  <p>Kind regards
