Calyptos Configuration File¶

Calyptos configuration files are written in YAML syntax. Below is a guide on what can be provided and how to structure your configuration files.

The a typical config file has the following structure:

name: HadEupa
description: This Euca install will run our Hadoop workloads!
default_attributes:
  eucalyptus:
    topology:
      clc-1: 10.111.5.138
      user-facing:
      - 10.111.5.138

      clusters:
        hadoop-a:
          cc-1: 10.111.5.138
          nodes: 10.111.5.102
          sc-1: 10.111.5.138
    network:
      mode: EDGE
      private-interface: br0
      public-interface: br0
      bridge-interface: br0
      bridged-nic: em1
      config-json:
        Clusters:

          PrivateIps:
          - 10.111.31.43-10.111.31.50
          Subnet:
            Gateway: 10.111.0.1
            Name: 10.111.0.0
            Netmask: 255.255.0.0
            Subnet: 10.111.0.0
        InstanceDnsServers:
        - 10.111.5.138
        PublicIps:
        - 10.111.31.35-10.111.31.42
    system-properties:
      cloudformation.url_domain_whitelist: '*s3.amazonaws.com,*qa1.eucalyptus-systems.com'

Lets take a look at each section and figure out what each does.

Name ¶

This is a short name used to refer to your cloud. It must not contain any spaces or underscores.

Description ¶

This can be a sentence that further identifies your cloud and its purpose moving forward.

Default Attributes ¶

Default attributes are applied to all machines in your deployment. These can be seen as “global” configuration values. This section is broken down by subsystem. For example, there are sections for:

eucalyptus

midokura

riakcs

In each of these sections we can configure and tune each set of components that make up our cloud infrastructure. Lets take a look at each section more in depth.

eucalyptus ¶

The eucalyptus section is likely to be the one most heavily interacted with. This section helps to define the Eucalyptus specific configuration of your deployment. This includes but isn’t limited to:

Component topology

Networking configuration

System properties

topology ¶

Example:

topology:
  clc-1: 10.111.5.138
  user-facing:
  - 10.111.5.138
  walrus: 10.111.5.138
  clusters:
    hadoop-a:
      cc-1: 10.111.5.138
      nodes: 10.111.5.102
      sc-1: 10.111.5.138

This section describes not only where to connect to your hosts but also which components should be installed on each. The cloud global components are defined by the following keys in the topology section:

clc-1: The primary cloud controller host

user-facing: A list of user-facing service hosts

walrus: The host to install the walrus on

The cluster level components are defined in a dictionary where the key is the intended name of the cluster. In our example above the cluster name is hadoop-a. Inside each of the specific cluster sections the following hosts must be defined:

cc-1: The primary cluster controller

sc-1: The primary storage controller

nodes: This is a space separated string of the node controllers in this cluster

network ¶

Example:

network:
  mode: EDGE
  private-interface: br0
  public-interface: br0
  bridge-interface: br0
  bridged-nic: em1
  config-json:
    Clusters:
    - Name: hadoop-a
      PrivateIps:
      - 10.111.31.43-10.111.31.50
      Subnet:
        Gateway: 10.111.0.1
        Name: 10.111.0.0
        Netmask: 255.255.0.0
        Subnet: 10.111.0.0
    InstanceDnsServers:
    - 10.111.5.138
    PublicIps:
    - 10.111.31.35-10.111.31.42

The network section defines global attributes for cloud level networking as well as the networking parameters that are used on the node controllers.

The mode is a string that can be one of the following:

EDGE
VPCMIDO
MANAGED
MANAGED-NOVLAN

The following params are available at the global level:

private-interface and public-interface keys - map to the VNET_PRIVINTERFACE and VNET_PUBINTERFACE respectively for the eucalyptus.conf on both cluster and node controllers
bridge-interface - maps to the VNET_BRIDGE parameter in eucalyptus.conf for node controllers

The config-json section has the same structure as defined in the Eucalyptus documentation.

system-properties ¶

Example:

system-properties:
  cloudformation.url_domain_whitelist: '*s3.amazonaws.com,*qa1.eucalyptus-systems.com'

This section allows the overriding of Eucalyptus system properties that would usually be set using euca-modify-property. Each key in this section is the name of a property, its corresponding value is what we will set that property to during deployment. In the case of the example above we will run the following after the cloud has been fully deployed:

euca-modify-property -p cloudformation.url_domain_whitelist='*s3.amazonaws.com,*qa1.eucalyptus-systems.com'

midokura ¶

Example:

midokura:
  bgp-peers:
  - local-as: 65949
    peer-address: 10.116.133.173
    port-ip: 10.116.133.162
    remote-as: 65000
    route: 10.116.151.0/24
    router-name: eucart
