This document describes the behavior of Vagrant Cloud after an organization is migrated to HCP Vagrant Registry. For information on migrating to HCP Vagrant Registry please see the migration guide.

Vagrant Cloud Redirects

After an organization has been migrated to HCP Vagrant Registry any requests Vagrant Cloud receives for that organization, or any boxes within that organization, will be automatically redirected to the proper location on HCP Vagrant Registry.

API

API requests to Vagrant Cloud for organizations that have been migrated to HCP Vagrant Registry will be automatically proxied to HCP.

Authenticated Requests

Authenticated API requests for migrated organizations will be proxied to HCP Vagrant Registry. This will require an HCP access token to be available to Vagrant Cloud to complete the request. Vagrant Cloud supports a composite access token comprised of the Vagrant Cloud access token and the HCP access token allowing seamless interactions with organizations that still remain on Vagrant Cloud as well as organizations that have been migrated to HCP Vagrant Registry.

The format of the composite access token is:

<VAGRANT_CLOUD_TOKEN>;<HCP_TOKEN>

If all organizations have been migrated to HCP Vagrant Registry the Vagrant Cloud access token will not be needed. The format of the access token is:

;<HCP_TOKEN>

HCP Access Token

The following prerequisites are required for generating an HCP access token:

• HCP Service Principal
• HCP CLI

Using the CLIENT_ID and CLIENT_SECRET from the HCP service principal login to HCP using the hcp command:

hcp auth login --client-id=CLIENT_ID --client-secret=CLIENT_SECRET

Once authenticated the access token can be printed using the following command:

hcp auth print-access-token

Vagrant Cloud Composite Token

The Vagrant CLI supports using the VAGRANT_CLOUD_TOKEN environment variable to hold the access token used for authentication. This environment variable can be set with both access tokens to allow request for migrated organization and unmigrated organizations to both work as expected. As noted above, the format of the composite token will consist of: the Vagrant Cloud access token, a semi-colon, and the HCP access token. An example of setting the environment variable would be:

export VAGRANT_CLOUD_TOKEN="<VAGRANT_CLOUD_TOKEN>;<HCP_TOKEN>"

The hcp command can also be used to provide the HCP access token to reduce the need for copying and pasting the access token:

export VAGRANT_CLOUD_TOKEN="<VAGRANT_CLOUD_TOKEN>;$(hcp auth print-access-token)"

If all organizations have been migrated to HCP Vagrant Registry, only the HCP access token will be needed:

export VAGRANT_CLOUD_TOKEN=";$(hcp auth print-access-token)"

Packer

After migrating to HCP, box uploads may fail when using the vagrant-cloud post-processor. This is due to the HCP access token used in the composite token expiring prior to the post-processor being executed.

To resolve this issue, a new Packer post-processor has been introduced: vagrant-registry. This post-processor iteracts directly with the HCP Vagrant Box Registry and removes the requirement of a composite access token. The configuration of the vagrant-registry post-processor matches the configuration of the vagrant-cloud post-processor with the exception of the authentication settings which requires a client_id and client_secret value instead of the access_token used by the vagrant-cloud post-processor.
