etcdpasswd

etcdpasswd manages Linux users and groups with a central database on etcd. This repository provides following two programs:

• ep-agent: a background service that watches etcd database and synchronize Linux users/groups.
• etcdpasswd: CLI tool to edit the central database on etcd.

Build

$ go install github.com/cybozu-go/etcdpasswd/...

Installation

1. Prepare an etcd cluster.

2. Create /etc/etcdpasswd/config.yml.

   This file provides parameters to connect to the etcd cluster. A sample configuration looks like this:

   endpoints:
     - http://12.34.56.78:2379
   username: cybozu
   password: xxxxxxxx
   
   tls-cert-file: /etc/etcdpasswd/etcd.crt
   tls-key-file: /etc/etcdpasswd/etcd.key

3. Run ep-agent.

   A sample systemd unit file is available at cmd/ep-agent/ep-agent.service. Use it to run ep-agent as a systemd service as follows:

   $ sudo cp $GOPATH/bin/ep-agent /usr/local/sbin
   $ sudo cp ep-agent.service /etc/systemd/system
   $ sudo systemctl daemon-reload
   $ sudo systemctl enable ep-agent.service
   $ sudo systemctl start ep-agent.service

4. Use etcdpasswd to initialize the database.

   $ etcdpasswd set start-uid 2000
   $ etcdpasswd set start-gid 2000
   $ etcdpasswd set default-group cybozu
   $ etcdpasswd set default-groups sudo,adm
