The following example shows the schema of an image pushed event:
[{
"id": "831e1650-001e-001b-66ab-eeb76e069631",
"source": "/subscriptions/<subscription-id>/resourceGroups/<resource-group-name>/providers/Microsoft.ContainerRegistry/registries/<name>",
"subject": "aci-helloworld:v1",
"type": "Microsoft.ContainerRegistry.ImagePushed",
"time": "2018-04-25T21:39:47.6549614Z",

"size": 3023,
"digest": "sha256:213bbc182920ab41e18edc2001e06abcca6735d87782d9cef68abd83941cf0e5",
"length": 3023,
"repository": "aci-helloworld",
"tag": "v1"
},
"request": {
"id": "7c66f28b-de19-40a4-821c-6f5f6c0003a4",

}
},
"specversion": "1.0"
}]
The schema for an image deleted event is similar:
[{
"id": "f06e3921-301f-42ec-b368-212f7d5354bd",
"source": "/subscriptions/<subscription-id>/resourceGroups/<resource-group-name>/providers/Microsoft.ContainerRegistry/registries/<name>",
"subject": "aci-helloworld",
"type": "Microsoft.ContainerRegistry.ImageDeleted",
"time": "2018-04-26T17:56:01.8211268Z",
"data": {
"id": "f06e3921-301f-42ec-b368-212f7d5354bd",
"timestamp": "2018-04-26T17:56:00.996603117Z",
"action": "delete",
"target": {
"mediaType": "application/vnd.docker.distribution.manifest.v2+json",
"digest": "sha256:213bbc182920ab41e18edc2001e06abcca6735d87782d9cef68abd83941cf0e5",
"repository": "aci-helloworld"
},
"request": {

"host": "demo.azurecr.io",
"method": "DELETE",
"useragent": "python-requests/2.18.4"
}
},
"specversion": "1.0"
}]
The schema for a chart pushed event is similar to the schema for an imaged pushed event, but it doesn't include a request object:

"action":"chart_push",
"target":{

"repository":"repo",
"tag":"mychart-1.0.0.tgz",
"name":"mychart",
"version":"1.0.0"
}
},
"specversion": "1.0"
}]
The schema for a chart deleted event is similar to the schema for an imaged deleted event, but it doesn't include a request object:
[{
"id": "39136b3a-1a7e-416f-a09e-5c85d5402fca",
