etcdv3-ruby

Ruby client for Etcd V3

Note: This is under active development and is not feature complete

Getting Started

To install etcdv3, run the following command:

gem install etcdv3

Establishing a connection

require 'etcdv3'

# Insecure connection
conn = Etcd.new(url: 'http://127.0.0.1:2379')

# Secure connection using default certificates
conn = Etcd.new(url: 'https://hostname:port')

# Secure connection with Auth
conn = Etcd.new(url: 'https://hostname:port', user: "gary", password: "secret")

# Secure connection specifying own certificates
# Coming soon...

Adding and Fetching Keys

 # Put
 conn.put("my", "value")

 # Get
 conn.get("my")

 # Get Key Range
 conn.get('my', 'myyyy')

User Management

 # Add User
 conn.add_user('admin', 'secret')

# Delete User
conn.delete_user('admin')

# List users
conn.user_list

Role Management

# Add Role
conn.add_role('rolename')

# Grant Permission to Role
conn.grant_permission_to_role('rolename', 'readwrite', 'a', 'z')

# Delete Role
conn.delete_role('rolename')

# List Roles
conn.role_list

Authentication Management

# Configure a root user
conn.add_user('root', 'mysecretpassword')

# Grant root user the root role
conn.grant_role_to_user('root', 'root')

# Enable Authentication
conn.enable_auth

After you enable authentication, you must authenticate.

# This will generate and assign an auth token that will be used in future requests.
conn.authenticate('root', 'mysecretpassword')

Disabling auth will clear the auth token and all previously attached user information

conn.disable_auth
