Git Out

A command-line tool to automatically backup Git repositories from GitHub or anywhere.

The gitout tool will clone git repos from GitHub or any other git hosting service. If the repository was already cloned, it will fetch any updates to keep your local copy in sync.

When you add your GitHub username and a token, gitout will discover all of your owned repositories and synchronize them automatically. You can opt-in to having repositories that you've starred or watched synchronized as well.

The cloned repositories are bare. In other words, there is no working copy of the files for you to interact with. If you need access to the files, you can git clone /path/to/bare/repo.

Installation

Rust

If you have Rust installed you can install the binary by running cargo install gitout.

Docker

The binary is available inside the jakewharton/gitout Docker container which can run it as a cron job.

Mount a /data volume which is where the repositories will be stored. Mount the /config folder which contains a config.toml or mount a /config/config.toml file directly. Specify a CRON environment variable with a cron specifier dictating the schedule for when the tool should run.

$ docker run -d \
    -v /path/to/data:/data \
    -v /path/to/config.toml:/config/config.toml \
    -e "CRON=0 * * * *" \
    jakewharton/gitout

For help creating a valid cron specifier, visit cron.help.

To be notified when sync is failing visit https://healthchecks.io, create a check, and specify the ID to the container using the HEALTHCHECK_ID environment variable (for example, -e "HEALTHCHECK_ID=...").

To write data as a particular user, the PUID and PGID environment variables can be set to your user ID and group ID, respectively.

If you're using Docker Compose, an example setup looks like;

services:
  gitout:
    image: jakewharton/gitout:latest
    restart: unless-stopped
    volumes:
      - /path/to/data:/data
      - /path/to/config:/config
    environment:
      - "CRON=0 * * * *"
      #Optional:
      - "HEALTHCHECK_ID=..."
      - "PUID=..."
      - "PGID=..."

Note: You may want to specify an explicit version rather than latest. See https://hub.docker.com/r/jakewharton/gitout/tags or CHANGELOG.md for the available versions.

Binaries

TODO GitHub releases download binaries #8

Usage

$ gitout --help
gitout 0.1.0

USAGE:
    gitout [FLAGS] <config> <destination>

FLAGS:
        --dry-run    Print actions instead of performing them
    -h, --help       Prints help information
    -V, --version    Prints version information
    -v, --verbose    Enable verbose logging

ARGS:
    <config>         Configuration file
    <destination>    Backup directory

Configuration specification

Until version 1.0 of the tool, the TOML version is set to 0 and may change incompatibly between 0.x releases. You can find migration information in the CHANGELOG.md file.

version = 0

[github]
user = "example"
token = "abcd1234efgh5678ij90"

[github.clone]
starred = true  # Optional, default false
watched = true  # Optional, default false
# Extra repos to synchronize that are not owned, starred, or watched by you.
repos = [
  "JakeWharton/gitout",
]
# Repos temporary or otherwise that you do not want to be synchronized.
ignored = [
  "JakeWharton/TestParameterInjector",
]

# Repos not on GitHub to synchronize.
[git.repos]
asm = "https://gitlab.ow2.org/asm/asm.git"

Creating a GitHub token

Visit https://github.com/settings/tokens
Click "Generate new token"
Type "gitout" in the name field
Select the "repo", "gist", and "read:user" scopes
- repo: Needed to discover and clone private repositories (if you only have public repositories then just public_repo will also work)
- gist: Needed to discover and clone private gists (if you only have public gists then this is not required)
- read:user: Needed to traverse your owned, starred, and watched repo lists
Select "Generate token"
Copy the value into your config.toml as it will not be shown again

Development

If you have Rust installed, a debug binary can be built with cargo build and a release binary with cargo build --release. The binary will be in target/debug/gitout or target/release/gitout, respectively. Run all the tests with cargo test. Format the code with cargo fmt. Run the Clippy tool with cargo clippy.

If you have Docker but not Rust, run docker build . which will do everything. This is what runs on CI.
