We have a lot of build processes that utilize Terraform to perform destroy and apply command. This results in a ton of terraform inits that download the same provider plugins over and over again. You can recover this download time and reduce the risk of Hashicorp giving you the banhammer (which I haven’t heard of them doing but you never know) by configuring the provider plugin cache.

Give it a shot and speed up your terraform jobs!
