Should the Content-Type be json/x-scylla? or application/json ?

[fruch]

Yeah, we should do better here.

But I suggest doing it gradually, and with advancing smi_version

[yaronkaikov]

@roydahan How is it related to us? it's in SCT,

[mykaul]

I assume it's from https://github.com/scylladb/scylla-cluster-tests/blob/a609915e4a590659835a17058c5b4c3c52f6522a/sdcm/sct_provision/aws/user_data.py#L77

[fruch]

this is an issue for SMI

scylla-machine-image/lib/user_data.py

Line 37 in 6e92623

if part.get_content_type() in ('x-scylla/json', 'x-scylla/yaml'):

this is o.k. for cloud-init to complain on our own define mime type
it probably can be change to something that won't get those errors, but the idea that only our code would read those parts, i.e. other mime types that might be used by cloud-init itself shouldn't be used.

anyhow it's not an issue with SCT
