val os_family_to_string : os_family -> string
os_family_to_string os
returns a string representing the OS family.
val opam_repository : os_family -> string
opam_repository os_family
returns the git URL to the default Opam repository.
val personality : os_family -> Ocaml_version.arch -> string option
personality os_family arch
returns the personality associated to the architecture, if os_family
is `Linux
.
is_same_distro d1 d2
returns whether d1
is the same distro as d2
, regardless of their respective versions.
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 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.

The package manager used by a distro.

val __package_manager_of_sexp__ : Sexplib0.Sexp.t -> package_manager
val package_manager : t -> package_manager
package_manager t
returns the package manager used by that distribution. Many derived distributions (such as OracleLinux) share the same package manager from a base distribution (such as CentOS).
val bubblewrap_version : t -> (int * int * int) option
bubblewrap_version t
returns the version of bubblewrap available on that distribution.
val tag_of_distro : t -> string
tag_of_distro t
convert a distribution t
to a Docker Hub tag.
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_distro 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 base_distro_tag : ?arch:Ocaml_version.arch -> t -> string * string
base_distro_tag ?arch t
will return a tuple of a Docker Hub user/repository and tag for which the base image of a distribution can be found (e.g. opensuse/leap
,15.0
which maps to opensuse/leap:15.0
on the Docker Hub). This base image is in turn can be used to generate opam and other OCaml tool Dockerfiles. arch
defaults to x86_64
and can vary the base user/repository since some architecture are built elsewhere.
val distro_arches : Ocaml_version.t -> t -> Ocaml_version.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 : Ocaml_version.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
.
val active_distros : Ocaml_version.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 : Ocaml_version.arch -> t list
Tier 1 distributions are those supported for the full matrix of compiler versions in the opam build infrastructure. The Docker base images will compile a base image for every OCaml version, so this list should be added to sparingly.
val active_tier2_distros : Ocaml_version.arch -> t list
Tier 2 distributions are those supported for a limited set of compiler versions in the opam build infrastructure. The distros in this list are also tested for packages in the opam repository.
val active_tier3_distros : Ocaml_version.arch -> t list
Tier 3 distributions are those supported for a limited set of compiler versions in the opam build infrastructure. While these distros will have base images compiled for them, they are not widely tested. Distros maybe here as they are on the way to being deprecated, or new and still experimental.
