Using Anka Controller

Anka Controller is the central management system of Anka Build and provides a simple and extensible interface for provisioning and managing on-demand macOS VMs on a cluster of mac hardware (Anka Build nodes). If you use CI tools like Jenkins or Teamcity, integrate them with Anka controller using controller REST APIs to provision macOS VMs on-demand for CI job requests. For Jenkins, use the Anka Build plugin.

Using Anka Controller

After the successful installation of Anka Controller, Controller must be configured to communicate with Anka Registry, the Anka nodes, and your CI system.

By default, Anka Controller setup doesn’t use TLS. To configure TLS on the controller, you can contact for additional setup instructions.

Now, connect your Anka nodes (any Apple hardware running the Anka Build application package) with the Controller by running this command sudo ankacluster join -g on each of the Anka Build nodes (mac machines on which you have installed ankabuild.pkg). It’s recommended to use the -g flag with join and disjoin commands.

ankacluster join --help
   ankacluster join - join a cluster

   ankacluster join [command options] http://controller-address[:port]

   --queue-address value, -q value        queue-address[:port] (optional)
   --max-vm-count NUMBER, -m NUMBER       Maximum NUMBER of VMs this node is allowed to run (optional) (default: 2)
   --name NAME, -n NAME                   Node NAME alias (optional)
   --tls, -t                              Use tls for communicating with the queue (optional)
   --keystore PATH, -k PATH               PATH to certificate and keystore (PEM, PKCS12) (optional)
   --keystore-pass PASSWORD, -p PASSWORD  PASSWORD for certificate and keystore (optional)
   --cacert PATH, -c PATH                 PATH to CA bundle file (PEM/X509) (optional)
   --global, -g                           Install agent into system domain

In the command, http://controller-address[:port] is the Controller IP.

If your controller is configured on port 80, then leave the [:port] empty. Else, specify the port no.

--max-vm-count value variable is used to set a max limit of concurrent VMs that can be run on the node through the controller. For example if you are using mac minis for your build or test jobs, you want to limit to 2 concurrent VMs. On a Mac Pro, you can configure a higher value.

--name is used to associate a specific name to this Build node. When setting up Anka Build cloud on multiple build nodes, name value parameter identifies each of these nodes.

sudo ankacluster join -g -m 6 -n 228mpro http://XX.XXX.XXX.XXX:8090
Testing connection to controller...: Ok
Testing connection to the registry...: Ok
Testing connection to the queue...: Ok
Cluster join success

To disjoin a build node from a cluster, use the following command.

sudo ankacluster disjoin -g

Adding/Removing build nodes dynamically

You can add or remove build nodes from Anka macOS cloud in a dynamic fashion by executing sudo ankacluster join -g & sudo ankacluster disjoin -g from the build nodes. This does not impact your CI job execution. Controller automatically distributes the jobs across available(joined) nodes.

Accessing and working with controller management UI

In release 1.2, we introduced a web UI service to controller. Access it by going to your controller IP -

You can view the status of your Anka Build macOS cloud from this UI and also perform basic management operations.

Dashboard View

This view displays the total active build nodes, running VM instances, instance run capacity utilization, registry storage consumption, average cpu and ram utilization across the entire cloud.


Nodes View

Click on nodes to go to node list view.

You can view all active build nodes, instances running on them, their cpu and ram utilization. From this view, you can modify the concurrent VM capacity for each node.


Templates View

Click on templates to look at all VMs stored in the registry.


Click on an individual template to view all versions/tags for that template.


Click on distribute to all nodes to pre-load the most frequently used Vm templates for your build/test jobs on all build nodes. This will reduce the time for first time job execution on Anka Build cloud.

Note - Once a job executes on a build node ina specific VM, the original VM template used for this job is cached on the node. Hence, any subesequent job executions don’t download Vmf rom the registry. The VM template is only downloaded when there is a brand new VM template or a new tag to an existing VM template. Download of a VM template with a new tag is only incremental.


Distribution to all nodes is complete.


Instances View

Click on Instances to get a list of all running instances on the cloud.


Manually starting instances

Click on create instance to manually start instances using a specific VM template/tag on the cloud.


Controller REST APIs

Use the REST APIs to integrate Anka Build cloud with your CI system. For Jenkins, use the Anka Jenkins Plugin.

To provision and start VMs (Start VM instance will start N count of instances of a particular type across the node cluster)

url= "/api/v1/vm", 
body="VM UUID, tag, version, count, node_id, startup_script"  (node_id, count, tag, version and startup_script are optional. If not provided, the latest version will be used, otherwise whatever tag is specified will be pulled on the nodes. By default count is 1. If node_id is not specified the VM could be scheduled on any node)
startup_script is base64 encoded string of the script to be executed after the instance is started
Returns: Operation Result, Array of instance UUIDs
Example Body: {"vmid":"226d946b-2467-11e7-84b7-a860b60fd826", “count”=”10”, startup_script=”IyEvYmluL2Jhc2gNCmV4cG9ydCBBPSJhYWEiDQoNCg==”}
