Working with the 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.
