Working with the Registry and API

How to work with the Anka Registry and API

Anka registry provides an easy way to store, version, and distribute macOS VMs that are used for CI and development. Once you’ve completed creation and setup of your VMs, use anka registry command to work with the registry.

Store your build and test VM templates in the registry.
Then, you can pull them, modify them and push them again with a different tag to the Registry. This way you can maintain versions. Pull specific VM template and tag to a different machine running Anka package.

Registry operations are available through Anka Client command line and through Registry REST APIs.

Working with registry using Anka CLI

View all of the available registry commands by running anka registry --help.

> sudo anka registry --help
Usage: anka registry [OPTIONS] COMMAND [ARGS]...

  Configure and control the Anka Cloud Registry

Options:
  -r, --remote TEXT           Set the registry name (instead of 'default')
  -a, --registry-path TEXT    Set the registry URL (instead of 'default')
  -c, -i, --cert, --pem PATH  Path to your node certificate (if certificate authentication is enabled)
  -k, --key PATH              Path to your node certificate key if the client/node certificate doesn't contain one
  --cacert, --root-cert PATH  Path to a CA Root certificate
  --insecure                  Skip TLS verification
  --help                      Display usage information

Commands:
  add                  Add a registry
  check-download-size  Return the size of the template and tag
  delete               Remove the registry from your configuration
  describe             Show a VM template description and tags
  list                 List VMs in registry
  list-repos           List registries you have configured
  pull                 Pull the specified VM template (and latest...
  push                 Push a VM template (and tag) to the Cloud...
  set                  Set default registry

Add registry to a Node/machine running Anka

anka registry add <givesomename> <registryURLwithport>

You can add/define multiple registries to a node. The last one added is treated as current. To change current use the set command.

Set Current registry

anka registry set <previouslydefiniedname>

Push VM to the Registry

anka registry push -d <description> -t <tag> {vmNameOrUUID}

Pull VM from the Registry

anka registry pull -t <tag> {vmNameOrUUID}

Pull VM from the Registry with Shrink

anka registry pull -s -t <tag> {vmNameOrUUID}

For example, let’s say you have V1, V2 tags in the Registry for a VM. You pull V2. Then, you pull V1 with -s flag. It will optimize the local disk space usage by deleting all V2 related tag/version files.

Push independent VM as new tag of existing VM in Registry

anka registry push NEW_VM -v EXISTING_VM_IN_REGISTRY -t NEW_TAG

For example, let’s say you have a VM1, with latest tag t2. Now, you want to push a completely independent VM2 as the next tag to VM1. You will use anka registry push VM2 -v VM1 -t NEW_TAG.

Revert

Reverting is a potentially dangerous operation. It will revert all tags which came AFTER the one you’re targeting. We recommend a multi-template-single-tag approach instead to avoid this.

Parameter	Type	Description
id	string	The Template id.

Optional Data Parameters

Parameter	Type	Description	Default
tag	string	The Tag to revert to. Newer versions will also be deleted	Latest
version	int	The number of the version to revert to, 0 indexed	Latest

Returns:

Status: Operation Result (OK|FAIL)
message: Error message in case of an error

CURL Example

# Delete latest version

curl -X DELETE  "http://anka.registry.net:8089/registry/revert?id=00510971-5c37-4a60-a9c6-ea185397d9b4"
