Manifest Config
Customizing the configuration object in Go is as simple as passing oras.WithConfig() option to oras.Push().
Suppose there is a descriptor configDesc
referencing the config file in the content provider store
.
configDesc := ocispec.Descriptor{
MediaType: mediaType, // config media type
Digest: digest, // sha256 digest of the config file
Size: size, // config file size
}
To push with custom config, execute
_, err := oras.Push(ctx, resolver, ref, store, contents, oras.WithConfig(configDesc))
If the caller wants to customize the config media type only, pass the oras.WithConfigMediaType() option to oras.Push().
_, err := oras.Push(ctx, resolver, ref, store, contents,
oras.WithConfigMediaType("application/vnd.oras.config.v1+json"))
