Hcloud

This is an unoffical ruby client for HetznerCloud Api service.

Its currently in development and lacking a lot of feature. The bindings are also not considered stable.

Installation

Add this line to your application's Gemfile:

gem 'hcloud'

And then execute:

$ bundle

Or install it yourself as:

$ gem install hcloud

Usage

Client

Create a client instance.

c = Hcloud::Client.new(token: "<your project token>")

Create a client instance which fully handles concurrent pagination

c = Hcloud::Client.new(
  token: "<your project token>", 
  auto_pagination: true,
  concurrency: 50 # default 20
)

Expose client connection to class level

Hcloud::Client.connection = Hcloud::Client.new(...)

Client concurrency

Each action could be handled concurrently. The actual downsides are located at the exception handling. Means one request could break the whole bunch of requests, you currently have to deal with that.

servers = []
client.concurrent do
  10.times do 
    servers << client.servers.create(...)
  end
end 

servers.each do |(action, server, root_password)|
  # do something with your servers ...
end

Server Resource

List servers (basic client)

# default page(1)
# default per_page(50)
c.servers.page(2).per_page(40).each do |server|
  server.datacenter.location.id #=> 1
end

List servers (auto pagination client)

# default nolimit
c.servers.limit(80).each do |server|
  server.datacenter.location.id #=> 1
end

List with registered class level client

Server.limit(10).each do |server|
  # do something with the server
end

Create a server

Nonblocking:

c.servers.create(name: "moo5", server_type: "cx11", image: "ubuntu-16.04")
#=> [#<Hcloud::Action>, <#Hcloud::Server>, "root_password"]

Wating for finish:

action,server = c.servers.create(name: "moo5", server_type: "cx11", image: "ubuntu-16.04")

while action.status == "running"
  puts "Waiting for Action #{action.id} to complete ..."
  action = c.actions.find(action.id)
  server = c.servers.find(server.id)
  puts "Action Status: #{action.status}"
  puts "Server Status: #{server.status}"
  puts "Server IP Config: #{server.public_net["ipv4"]}"
  sleep 5
end

Update servers' name

c.servers.count
#=> 2
c.servers.first.update(name: "moo")
#=> #<Hcloud::Server>
c.servers.each{|x| x.update(name: "moo") }
Hcloud::Error::UniquenessError: server name is already used

Delete a server

c.servers.first.destroy
#=> #<Hcloud::Action>
