}Policy
Set the repository policy
Grants access to principals outside the owning account. With
principal * this makes the repository publicly pullable, which is
how a base-image repository is shared.
Replaced wholesale, never merged: a caller who removes a statement from a policy they fetched expects the grant gone.
Every statement must name a principal, must use only registry:
actions, and must name this repository’s own CRN (or *, which
means the same thing here). not_actions and not_resources are
refused — a negated set cannot be bounded to one repository by
inspection.
Cross-account access requires the caller’s own IAM policy to allow the action as well. A resource policy widens what this repository permits; it cannot exceed what the caller’s organization permits.

}Requires the IAM action
registry:SetRepositoryPolicy. See REGISTRY permissions for the full list, what each one covers, and an example policy.Authorizations
An OAuth 2.0 bearer token, sent as Authorization: Bearer <token>.
This is the recommended way to authenticate.
Get one by exchanging a service account's access key pair at
POST /v1/oauth/token with grant_type=client_credentials. It is the
standard client-credentials grant, so any OAuth-aware library will
obtain and refresh it for you.
curl -s -u "$KEY_ID:$SECRET" -d grant_type=client_credentials \
https://iam.basaltic.sh/v1/oauth/token
Tokens last an hour by default. The same access key pair is separately your AWS SigV4 credential for the S3-compatible object endpoint, which speaks nothing else.
Path Parameters
Example:
"a1b2c3d4-5e6f-4a7b-8c9d-0e1f2a3b4c5d"
Body
application/json
A resource-based policy. Unlike an IAM policy, every statement must name a principal — the document is attached to a resource, so "who" cannot be implied by attachment.
