A request to store a container image is received from a device associated with a customer of a computing resource service provider. Validity of a security token associated with the request is authenticated using a cryptographic key maintained as a secret by the computing resource service provider. One or more layers of the container image is built based at least in part on at least one build artifact to form a set of built layers. The software image including the set of built layers is stored in a repository associated with the customer. A manifest of metadata for the set of built layers is stored in a database of a structured data store. The container image is obtained in the form of an obtained container image. The obtained container image is deployed as the software container in at least one virtual machine instance associated with the customer.
