I’ve decided to create a snap for Hashicorp’s Terraform, with the intention of migrating this to the Snapcrafter GitHub Organisation and ultimately upstream. Unfortunately the upstream name terraform is already in use by a snap (owned by @nhandler), which was last updated over a year ago and two major versions behind the current 0.13.x releases.
$ snap info terraform

safely and efficiently. Terraform can manage existing and popular service
providers as well as custom in-house solutions.
snap-id: 8vbHYTd6VDLMIlISfzZDxzCRUFeSdBqT
channels:
latest/stable: v0.11.11 2019-01-14 (216) 29MB -
latest/candidate: v0.11.11 2019-01-14 (216) 29MB -
latest/beta: v0.11.11 2019-01-14 (216) 29MB -
latest/edge: v0.11.11 2019-01-14 (216) 29MB -
By moving this to Snapcrafters, there would be greater visibilty and community involvement to keep the version current, as well as providing a certain level of assurance to users of the snap that it would be maintained more frequently by a trusted source (next best thing after upstream).
I’ve based the snapcraft.yaml on the vault snap being maintained by Snapcrafters.
Initial testing on my end seems to show the snap is functioning as intended, I am able to sucessfully create and destroy infrastructure in the cloud (tested with GCP). Plugins and Modules get initialised with no problem in my testing.
I’m interested to see the results testing this snap yields for other users.
Install instructions:
Due to the snap terraform being taken I have had to append my username to the snap, terraform-nightmayr. If the snap is accepted into Snapcrafters and as a result the use of the upstream name is transferred to this snap, the GitHub repo will be updated to reflect this.
Edge channel (devmode snap):
sudo snap install terraform-nightmayr --edge
Beta channel (strict confinement snap):
sudo snap install terraform-nightmayr --beta
Usage instructions:
From the terminal run within a directory containing a terraform project:
terraform-nightmayr.terraform init
terraform-nightmayr.terraform plan
terraform-nightmayr.terraform apply
terraform-nightmayr.terraform destroy
terraform-nightmayr.terraform -help (for a list of possible commands to run)
