Supported Docker container distributions

val sexp_of_t : t -> Ppx_sexp_conv_lib.Sexp.t

val t_of_sexp : Ppx_sexp_conv_lib.Sexp.t -> t

val __t_of_sexp__ : Ppx_sexp_conv_lib.Sexp.t -> t

val compare : t -> t -> int

compare a b is a lexical comparison function for t.

val resolve_alias : t -> t

resolve_alias t will resolve t into a concrete version. This removes versions such as Latest.

val distros : t list

Enumeration of the supported Docker container distributions

val latest_distros : t list

Enumeration of the latest stable (ideally LTS) supported distributions.

val master_distro : t

The distribution that is the top-level alias for the latest tag in the ocaml/opam2 Docker Hub build.

val builtin_ocaml_of_distro : t -> string option

builtin_ocaml_of_distro t will return the OCaml version supplied with the distribution packaging, and None if there is no supported version.

val tag_of_distro : t -> string

Convert a distribution to a Docker Hub tag. The full form of this is ocaml/TAG on the Docker Hub.

val distro_of_tag : string -> t option

distro_of_tag s parses s into a t distribution, and None otherwise.

val latest_tag_of_distro : t -> string

latest_tag_of_dsistro distro will generate a Docker Hub tag that is a convenient short form for the latest stable release of a particular distribution. This tag will be regularly rewritten to point to any new releases of the distribution.

val human_readable_string_of_distro : t -> string

human_readable_string_of_distro t returns a human readable version of the distribution tag, including version information.

val human_readable_short_string_of_distro : t -> string

human_readable_short_string_of_distro t returns a human readable short version of the distribution tag, excluding version information.

CPU Architectures

val sexp_of_arch : arch -> Ppx_sexp_conv_lib.Sexp.t

val arch_of_sexp : Ppx_sexp_conv_lib.Sexp.t -> arch

val __arch_of_sexp__ : Ppx_sexp_conv_lib.Sexp.t -> arch

val distro_arches : Ocaml_version.t -> t -> arch list

distro_arches ov t returns the list of architectures that distribution t is supported on for OCaml compiler version ov

val distro_supported_on : arch -> Ocaml_version.t -> t -> bool

distro_supported_on arch ov distro returns true if the combination of CPU arch, compiler version ov is available on the distribution distro.

Opam build infrastructure support

val active_distros : arch -> t list

active_distros arch returns the list of currently supported distributions in the opam build infrastructure. Distributions that are end-of-life upstream will rotate out of this list regularly.

val active_tier1_distros : arch -> t list

Tier 1 distributions are those supported for the full matrix of compiler versions in the opam build infrastructure.

val active_tier2_distros : arch -> t list

Tier 2 distributions are those supported for a limited set of compiler versions in the opam build infrastructure.
