Eucalyptus¶

Builder type: eucalyptus-kvm or eucalyptus-xen

Require Cloud Account: Yes www.eucalyptus.com

The Eucalyptus builder provides information for building and publishing the machine image for Eucalyptus. This builder supports KVM (eucalyptus-kvm) and Xen (eucalyptus-xen) based images for Eucalyptus.

The Eucalyptus builder requires cloud account information to upload and register the machine image to an Eucalyptus cloud platform.

The Eucalyptus builder section has the following definition:

{
  "builders": [
    {
      "type": "eucalyptus-kvm",
      ...the rest of the definition goes here.
    }
  ]
}

Building a Machine Image¶

For building an image, the valid keys are:

account (mandatory): an object providing the Eucalyptus cloud account information required to publish the built machine image.
installation (optional): an object providing low-level installation or first boot options. These override any installation options in the Stack section. The following valid keys for installation are:
- diskSize (mandatory): an integer providing the disk size of the machine image to create. Note, this overrides any disk size information in the stack. This cannot be used if an advanced partitioning table is defined in the stack.
disableRootLogin (optional): a boolean flag to determine if root login access should be disabled for any instance provisioned from the machine image.
type (optional): a string providing the machine image type to build. For Eucalyptus: eucalyptus-kvm or eucalyptus-xen

Publishing a Machine Image¶

To publish an image, the valid keys are:

account (mandatory): an object providing the Eucalyptus cloud account information required to publish the built machine image.
bucket (mandatory): a string providing the bucket where to store the machine image. Note, bucket names are global to everyone, so you must choose a unique bucket name that is not used by another user. The bucket name should not include spaces.
description (mandatory): a string providing a description of what the machine image does. The description of the machine image is displayed in the console. The description can only be up to 255 characters long. Descriptions longer than 255 characters will be truncated.
imageName (mandatory): a string providing the displayed name for the machine image.
kernelId (optional): a string providing the kernel Id when booting an instance from the machine image. Note that the kernel id must be already present on the cloud environment. If a kernel Id is not specified, then the default kernel Id registered on the cloud platform will be used.
ramdisk (optional): a string providing the ramdisk Id when booting an instance from the machine image. Note that the ramdisk Id must be already present on the cloud environment. If a ramdisk Id is not specified, then the default ramdisk Id registered on the cloud platform will be used.
type (optional): a string providing the machine image type to build. For Eucalyptus: eucalyptus-kvm or eucalyptus-xen

Eucalyptus Cloud Account¶

Key: account Used to authenticate to Eucalyptus.

The Eucalyptus cloud account has the following valid keys:

accountNumber (mandatory): a string providing the User ID or Eucalyptus account number of the user who is bundling the image. This value can be found in the eucarc file.
cloudCert (mandatory): a string providing the location of the cloud certificate. This may be a path or URL. To get the cloud certificate, login into your Eucalyptus admin console (for example https://myserver.domain.com:8443). Go to the Credentials ZIP-file and click on the button Download credentials. Unzip this file, you should find the certificate with the name cloud-cert.pem
file (optional): a string providing the location of the account information. This can be a pathname (relative or absolute) or an URL.
endpoint (mandatory): a string providing the URL of the Eucalyptus Walrus server. To get the walrus server information, login into your Eucalyptus admin console and click on the Configuration tab
name: (mandatory) a string providing the name of the cloud account. This name can be used in a builder section to reference the rest of the cloud account information.
queryId (mandatory): a string providing your Eucalyptus query id. To get this key, login into your Eucalyptus admin console (for example https://myserver.domain.com:8443). Go to Query Interface Credentials > Show keys, the query id will be displayed.
secretKey (mandatory): a string of your your Eucalyptus secret key. To get this key, login into your Eucalyptus admin console (for example https://myserver.domain.com:8443). Go to Query Interface Credentials > Show keys, the secret key will be displayed
type (optional): a string providing the cloud account type: eucalyptus.
x509PrivateKey (mandatory): a string providing the location of the X.509 certificate private key. This may be a path or URL. This is the private key of the X.509 certificate. To get an X.509 private key, login into your Eucalyptus admin console, go to Credentials ZIP-file and click on the button Download credentials. Unzip this file, you should find the private key with the name XXXX-XXXX-XXXX-pk.pem.
x509Cert (mandatory): a string providing the location of the X.509 certificate public key. This may be a path or URL. To get a X.509 certificate, login into your Eucalyptus admin console, go to the Credentials ZIP-file and click on the button Download credentials. Unzip this file, you should find the certificate with the name XXXX-XXXX-XXXX-cert.pem

Note

In the case where name or file is used to reference a cloud account, all the other keys are no longer required in the account definition for the builder.

Example¶

The following example shows an Eucalyptus builder with all the information to build and publish a machine image to Eucalyptus.

{
  "builders": [
    {
      "type": "eucalyptus-kvm",
      "account": {
        "type": "eucalyptus",
        "name": "My Eucalyptus Account",
        "accountNumber": "111122223333",
        "x509PrivateKey": "/home/joris/accounts/euca/euca-pk.pem",
        "x509Cert": "/home/joris/accounts/euca/euca-cert.pem",
        "cloudCert": "/home/joris/accounts/euca/cloud-cert.pem",
        "endpoint": "http://127.0.0.1/8773",
        "queryId": "WkVpyXXZ77rXcdeSbds3lkXcr5Jc4GeUtkA",
        "secretKey": "ir9CKRvOXXTHJXXj8VPRXX7PgxxY9DY0VLng"
      },
      "imageName": "CentOS Core",
      "description": "CentOS Base Image",
      "bucket": "ussprodbucket"
    }
  ]
}

Referencing the Cloud Account¶

To help with security, the cloud account information can be referenced by the builder section. This example is the same as the previous example but with the account information in another file. Create a json file euca-account.json.

{
  "accounts": [
    {
      "type": "eucalyptus",
      "name": "My Eucalyptus Account",
      "accountNumber": "111122223333",
      "x509PrivateKey": "/home/joris/accounts/euca/euca-pk.pem",
      "x509Cert": "/home/joris/accounts/euca/euca-cert.pem",
      "cloudCert": "/home/joris/accounts/euca/cloud-cert.pem",
      "endpoint": "http://127.0.0.1/8773",
      "queryId": "WkVpyXXZ77rXcdeSbds3lkXcr5Jc4GeUtkA",
      "secretKey": "ir9CKRvOXXTHJXXj8VPRXX7PgxxY9DY0VLng"
    }
  ]
}

The builder section can either reference by using file or name.

Reference by file:

{
  "builders": [
    {
      "type": "eucalyptus-kvm",
      "account": {
        "file": "/home/joris/accounts/euca-account.json"
      },
      "imageName": "CentOS Core",
      "description": "CentOS Base Image",
      "bucket": "ussprodbucket"
    }
  ]
}

Reference by name, note the cloud account must already be created by using account create.

{
  "builders": [
    {
      "type": "eucalyptus-kvm",
      "account": {
        "name": "My Eucalytpus Account"
      },
      "imageName": "CentOS Core",
      "description": "CentOS Base Image",
      "bucket": "ussprodbucket"
    }
  ]
}
