This page explains how to configure CORS on a\nCloud Storage bucket for a sample origin, the origin of the online\n[Shaka](https://shaka-player-demo.appspot.com/demo/) media player.\nTo [enable cross-origin resource\nsharing (CORS) on a Cloud Storage bucket](/storage/docs/using-cors#configure-cors-bucket), do the following:\n\n1. Create a JSON file that contains the following: \n\n ```\n [\n {\n \"origin\": [\"https://shaka-player-demo.appspot.com/\"],\n \"responseHeader\": [\"Content-Type\", \"Range\"],\n \"method\": [\"GET\", \"HEAD\"],\n \"maxAgeSeconds\": 3600\n }\n ]\n ```\n2. Run the following command after replacing \u003cvar translate=\"no\"\u003eJSON_FILE_NAME\u003c/var\u003e with the name of the JSON file you created in the previous step: \n\n ```\n gcloud storage buckets update gs://BUCKET_NAME --cors-file=JSON_FILE_NAME.json\n ```"]]
