Checkpoint is an internal service at Hashicorp that we use to check version information, broadcoast security bulletins, etc.
We understand that software making remote calls over the internet for any reason can be undesirable. Because of this, Checkpoint can be disabled in all of our software that includes it. You can view the source of this client to see that we're not sending any private information.
Each Hashicorp application has it's specific configuration option
to disable chekpoint calls, but the CHECKPOINT_DISABLE makes
the underlying checkpoint component itself disabled. For example
in the case of packer:
CHECKPOINT_DISABLE=1 packer build
Note: This repository is probably useless outside of internal HashiCorp use. It is open source for disclosure and because our open source projects must be able to link to it.
