Terraform Provider for Shaken Fist

What is this?

The Shaken Fist Terraform provider is a plugin for Terraform that allows for the full lifecycle management of resources on Shaken Fist.

Shaken Fist is a deliberately minimal cloud.

Shaken Fist Resources

This provider supports all Shaken Fist resources:

• Namespaces
• Instances
• Networks
• Floating IP's

Terraform Configuration

Examples of complete configuration files are available in the examples directory.

Provider

provider "shakenfist" {
    server_url = "http://sf-1:13000"
    namespace = "devtest"
    key = "longsecurekey"
}

Namespaces

• Multiple keys in the same namespace can be set by defining multiple shakenfist_key resources.
• Arbitrary metadata can be set on a namespace.

resource "shakenfist_namespace" "testspace" {
    name = "testspace"
    metadata = {
        owner = "bob"
        arbitrary = "clouds are awesome"
    }
}

resource "shakenfist_key" "key1" {
    namespace = shakenfist_namespace.testspace.name
    keyname = "key1"
    key = "secret"
}

Instances

• Memory is defined in MB
• Multiple disks can defined, and defined in GB. (Minimum one disk)
• Multiple network blocks can be defined.
• One video card can be defined, the default is Cirrus with 16384KB memory.
• Arbitrary metadata can be set on a namespace.

resource "shakenfist_instance" "jumpbox" {
    name = "jumpbox"
    cpus = 1
    memory = 1024
    disk {
        size = 8
        base = "cirros"
        bus = "ide"
        type = "disk"
    }
    disk {
        size = 3
        bus = "ide"
        type = "disk"
    }
    video {
        model = "cirrus"
        memory = 16384
    }
    network {
        network_uuid = shakenfist_network.external.id
    }
    network {
        network_uuid = shakenfist_network.special.id
        ipv4 = "10.0.1.17"
        model = "e1000"
        mac = "12:34:56:78:9a:Bc"
    }
    metadata = {
        user = "old man"
    }
}

Networks

• Arbitrary metadata can be set on a namespace.

resource "shakenfist_network" "external" {
    name = "external"
    netblock = "10.0.1.0/24"
    provide_dhcp = true
    provide_nat = true
    metadata = {
        purpose = "jump-hosts"
    }
}

Floating IP's

resource "shakenfist_float" "jump" {
    interface = shakenfist_instance.jumpbox.interfaces[0]
}

Testing

Terraform Provider acceptance tests require a Shaken Fist cluster and will modify resources on that cluster.

The provider acceptance tests are run using Make:

make testacc

The standard Shaken Fist environment variables must be set for the acceptance tests to run successfully.

SHAKENFIST_API_URL="http://sf-1:13000"
SHAKENFIST_NAMESPACE="dev"
SHAKENFIST_KEY="longsecurekey"

To run tests on Namespace resources, the Shaken Fist system privilege is required. Therefore the system namespace must be set:

SHAKENFIST_NAMESPACE=system
SHAKENFIST_KEY=Ukoh5vie
