nixery.dev uses the vnd.docker.container.image.v1 format, which is recognized by the OCI [1] and originally defined by Docker [2]. The config field in this image format, which this commit is about, is even portable between the Docker and OCI formats (the Docker Golang library embeds the OCI definition [3]). The attribute names in what's called ImageConfig in [3] are specified as PascalCase, which effectively means that the names Env and Cmd used by nixery need to be capitalized. The lowercase variant is not causing a lot of issues because most container tooling is written in Golang, which allows case-insensitive matches when deserializing JSON. Languages that parse strictly either miss the configuration values, or fail due to unknown attributes. This commit capitalizes Cmd and Env to accomodate strict parsers. [1]: |
