# hgkeeper
hgkeeper is an server for [mercurial](https://www.mercurial-scm.org/)
repositories. It provides access control for SSH access and public HTTP
access via hgweb.
Its original design is to be run in a container, but there are plans to make
it run stand-alone as well.
## License
hgkeeper is licensed under the GNU AFFERO GENERAL PUBLIC LICENSE version 3.
## Status
This project is brand new and only lightly tested. If you find issues, or are
looking for ways to help, please check out our
[issue tracker](https://issues.imfreedom.org/issues/HGKEEPER).
## Building
This project needs to generate some source files, so you'll need to first
install the embedding tool [esc](https://github.com/mjibson/esc).
```
$ go get -u 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:
```
$ go generate ./...
$ go build
```
## Getting Started
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.
### SSH Host Keys
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.
```
$ ssh-keygen -t rsa -b 4096 -o host-keys/ssh_host_rsa_key
```
### Create the hgkeeper repo
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 will create a new repository under `repos/hgkeeper`.
There are some additional options which you can discover via
`hgkeeper setup --help`.
### Running
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`.
## Usage
hgkeeper has a couple of modes of operation but `serve` is the main mode.
### setup
The `setup` command is used to bootstrap hgkeeper. It will create the
directory for the repositories as well as the hgkeeper repository.
After initial setup, please make sure to read the README.md in the hgkeeper
repository as it details how access control works.
### serve
The `serve` command is the main mode of operation which is to provide access to
the repositories.
## Access Control
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.
