Where are the container images coming from / how to publish images?

[theogravity]

It's not clear from the spec as to where the images come from.

"image": "hello-world@sha256:f5233545e43561214ca4891fd1157e1c3c563316ed8e237750d59bde73361e77"

Where is the hello-world image stored (eg docker hub)?

Is there an example repository for building images?

[theogravity]

Ah, it does look like docker hub is the default.

Searching for the hello-world image hash yields a lot of results on google.

Yeah, it uses the same format as docker to pull images. So hello-world@sha256:... pulls from docker hub but docker.example.com/hello-world@sha256:... pulls from a docker registry server at docker.example.com.
