hgkeeper is an server for [mercurial](https://www.mercurial-scm.org/)

repositories. It provides access control for SSH access.

It's original design is to be run in a container, but there are plans to make

it run stand-alone as well.

hgkeeper is licensed under the GNU AFFERO GENERAL PUBLIC LICENSE version 3.

This project is brand new and not even functional yet... But if you're

interested in helping, please do!!

This project needs to generate so source files, so you'll need to first install

the embedding tool [esc](https://github.com/mjibson/esc).

Once esc is installed, make sure it's available on your path.

Then you can build hgkeeper with the following commands:

The initial setup of hgkeeper has a few steps. Since hgkeeper is an SSH server

you will need to generate host keys for it, as well as create the initial

hgkeeper repository which contains the configuration for your install.

You can generate SSH host keys for whatever type you like, but rsa will cover

just about everyone. That said, a lot of people prefer to use ed25519 as well.

By default the SSH host keys will be looked for in the directory `host-keys` in

the current working directory. This can be changed with the `--ssh-host-keys-path` or `-H` command line arguments to hgkeeper.

This directory will be read and files in it will attempt to be loaded into the server.

To generate a host key you can use the following command, note that you can

create other types via the `-t` option, but you should read the `ssh-keygen`

documentation as other options are avaiable for each type.

Before you can run the server we need to create the hgkeeper admin repository.

This can be done via `hgkeeper setup`. You will need to pass the arguments

`--admin-username` which is the name of the admin user, as well as

`--admin-pubkey` which is the path to the SSH public key for the new admin

user. By default this we create a new repository under `repos/hgkeeper`.

There are some additional options which you can discover via

`hgkeeper setup --help`.

Once the SSH host keys and the hgkeeper repository are created, you can run

hgkeeper with `hgkeeper serve`. There are some other options that are

available so be sure to check out `hgkeeper serve --help`.

hgkeeper has a couple modes of operation but `serve` is the main mode.

The `setup` command is used to bootstrap hgkeeper. It will create the

directory for the repositores, the hgkeeper repository, and create an initial

`access.yml`.

The `serve` command is the main mode of operation which is to provide access to

the repositories.

Access control is defined in the `hgkeeper` repository that is created via the

`hgkeeper setup` command. It is implemented via [casbin](https://casbin.org)

using the RBAC with deny-override model as a base. More information can be

found in the [files](setup/resources/) that are placed in the `hgkeeper`

repository.
