A Registry Where Pushing v1.4.2 Twice Is an Error
Namespaces, repositories, VPC access and an internet allowlist on an Alibaba Cloud Container Registry Enterprise Edition instance. Repositories are private and their tags immutable unless set otherwise, auto-create is off, and the internet endpoint is only switched on - by the resource existing - when you give it CIDRs. Image cleanup is deliberately not managed.

Documentation
alicloud-container-registry
A private container registry on Alibaba Cloud Container Registry Enterprise Edition. Works with Terraform and OpenTofu
(>= 1.6), alicloud provider >= 1.283.0, < 2.0.
A public repository is pullable by anyone, with no credentials. Repositories and namespace defaults are PRIVATE, and PUBLIC is refused unless accept_public_repositories is set.
A tag can be overwritten unless it is immutable, which the API leaves off. Pushing v1.4.2 again silently replaces what every deployment pinned to it runs. Immutability is on per repository by default; a workflow that re-pushes latest will fail, which is the point.
Auto-create turns a typo into a repository, with the namespace's default visibility. Off by default.
The internet endpoint exists because the resource exists. Creating it switches the instance's public endpoint on and destroying it switches it off, so the module creates it only when internet_access_cidrs is set, and those CIDRs are the allowlist.
A VPC link without a DNS record is used by nothing. private_dns creates the PrivateZone record and defaults to true.
Image cleanup is not managed here. The lifecycle rule deletes images, and its documentation does not say clearly which tags its expression keeps.
Verification
Static validation runs tofu fmt, init, validate, tflint and checkov.
This module has not yet had a live test, so it is published as statically
validated with its live test pending and does not carry the live-tested mark.

ibm-container-registry
An IBM Cloud Container Registry namespace in the provider's region, with a retention policy that keeps the last ten images per repository and drops untagged ones, because without one every CI run adds an image until the account's storage quota refuses the next push. Quotas and the plan are account-wide and not managed here.
do-container-registry
Docker credentials for the registry never expire unless told to, so the login a CI job wrote to disk two years ago still pushes today; there is one registry per account; and the tier is a storage ceiling that turns into a failed push far from the cause. The registry, read-only credentials that live a day and read-write ones that live an hour, both re-issued on the next apply after expiry.
scaleway-container-registry
is_public makes every image in the namespace pullable by anyone, and the key CI pushes with is usually a person's API key with every permission that person has and no expiry. Private unless public is accepted by name, and on request an IAM application whose only permission is registry access in one project, with an API key that expires on the date you set.
ovh-container-registry
A registry's endpoint is public and every address may try a login until an IP restriction exists; the registry user is the credential and its password lands in state; and the plan is the storage ceiling. Allowed ranges expected with none accepted by name, one user created for the pipeline with its password as a sensitive output, and the plan looked up by name.
vultr-container-registry
A Vultr container registry that is private (public, which lets anyone pull every image, is accepted by name), on the plan you chose (start_up is free and small; the paid plans bill monthly from creation), in the region your clusters are in. The root user Vultr creates is not output; a robot user per cluster is the credential to hand out.
tencent-tcr
A Tencent Container Registry basic instance (pay-as-you-go; the premium editions are a purchase) with public network access off unless accepted by name and a security policy of allowed ranges when it is on, deletion protection on, versioned storage, and namespaces from a map that are private, scan every pushed image and refuse to pull one at or above the severity you set, with their repositories.
