Kakine

Kakine(垣根) is configuration management tool of Security Group on OpenStack.

Add this line to your application's Gemfile:

gem 'kakine'

And then execute:

$ bundle

Or install it yourself as:

$ gem install kakine

You can define Security Group configuration for OpenStack in YAML format as the following example.

app:
  rules:
    - direction: ingress
      protocol: tcp
      port: 443
      remote_ip: 0.0.0.0/0
    - direction: ingress
      protocol: tcp
      port: 80
      remote_ip: 0.0.0.0/0
  description: app rules
rails:
  rules:
    - direction: ingress
      protocol: tcp
      port: 3000
      remote_ip: 0.0.0.0/0

ports and remote_ips may be specified as arrays, in which case the rule is expanded to set of rules with all the combinations of them.

app:
  rules:
    - direction: ingress
      protocol: tcp
      port: [80, 443]
      remote_ip:
        - 192.0.2.0/24
        - 198.51.100.0/24

Top-level keys whose name both starts and ends with underscores (eg. _common_, _default_) are considered meta sections and do not correspond to security groups. These sections are useful to define values that commonly appears throughout the file, used with YAML's anchors and references.

_common_:
  - &net1 192.0.2.0/24
  - &net2 198.51.100.0/24

restricted_web:
  rules:
  - direction: ingress
    protocol: tcp
    port: 80
    remote_ip: *net1
  - direction: ingress
    protocol: tcp
    port: 80
    remote_ip: *net2
  description: Restricted HTTP access

You need to put a configuration file to home directory.

% cat ~/.kakine
auth_url: "http://your-openstack-endpoint/v2.0"
username: "admin"
password: "admin"

also, you can set some options.

client_cert: "/path/to/cert.pem"
client_key: "/path/to/key.pem"
region_name: "YourRegion"

run following command.

$ kakine show -t tenant_name # show Security Group of tenant_name
$ kakine apply -t tenant_name --dryrun # You can see all of invoke commands(dryrun)
$ kakine apply -t tenant_name # apply configuration into OpenStack

You can create or change Security Group on targeting tenant.

If you need to initialize your Security Gruop, you can get it via following command:

$ kakine show -t tenant_name > tenant_name.yaml
