Roper

A Repo Manager For The Rest Of Us

Current version is 0.1

Roper is a yum repo manager that will automatically watch added local yum repositories. Roper will watch for changes and run createrepo against the repos should any RPMs be added or removed. It will also serve up these repositories on a built in web server.

./roper -h
Roper is a server that can manage your Yum repositories, and serve them
up on a built in web server.  Most notably, it will watch configured
repositories and automatically run the 'createrepo' program
against them (if desired) when changes are detected.

Usage:
  roper [command]

Available Commands:
  repo        Perform an action on a repo
  serve       Run a server

Flags:
      --config string            config file (default is $HOME/.roper.yaml)
      --createrepo_path string   path to the 'createrepo' executable (default "/usr/local/bin/createrepo")
      --dbpath string            path to the roper database (default "/Users/alapidas/goWorkspace/src/github.com/alapidas/roper/roper.db")
  -t, --toggle                   Help message for toggle

Use "roper [command] --help" for more information about a command.

Roper uses Bolt as a database, and needs to persist this file somewhere. By default, it will persist to the directory that the roper executable lives in. This can be overridden with the --dbpath option.

To run Roper, first add a repository using an absolute path and a name:

./roper repo add /Users/alapidas/goWorkspace/src/github.com/alapidas/roper/hack/test_repos/docker/7/ DockerRepo
INFO[0000] created bucket (may have already existed)     bucket=repos
INFO[0000] created bucket (may have already existed)     bucket=packages
INFO[0000] Discovering repo                              name=DockerRepo path=/Users/alapidas/goWorkspace/src/github.com/alapidas/roper/hack/test_repos/docker/7/
INFO[0000] Running createrepo                            repo=DockerRepo
INFO[0000] Successfully discovered repo                  name=DockerRepo path=/Users/alapidas/goWorkspace/src/github.com/alapidas/roper/hack/test_repos/docker/7/

Then, we can serve this repo up:

./roper serve

By default, roper will serve your repos on a web server in a subdirectory of the repo name:

http://localhost:3000/DockerRepo/

Limitations

• The add and rm subcommands of repo require the server to be down, due to an exclusive lock held on the database

Developers

Building

make build

Testing

make test

Running

It's worth noting that you need the createrepo executbale somewher on your local system. For OSX, I used homebrew and a formula that someone wrote. Docker worked, but was more pain than it was worth. YMMV.

make run

TODO

• Handle more advanced features of createrepo
• Implement REST API on top of current model, allowing, at a minimum, CRUD access to repos and RPMs
• Implement RPC (or REST request/response) between roper client and roper server
• Make a Docker image for this
• Write more tests
