Our CI system uses packet.net to provision instances and to test code there. To accomplish this we are running packet-provision.sh script which is a thin wrapper over terraform code. This mechanism creates machines based on images built by using paulfantom/packet-image repository.

Script is able to provision and deprovision one instance in packet.net. It also takes care of tagging that instance, assigning unique name to it and creating temporary ssh key (private key is located in /tmp/packet_id_rsa unless TF_VAR_ssh_key_path was previously set). Script can be configured with following environment variables:

• PACKET_AUTH_TOKEN - packet.net API authentication token
• TF_VAR_packet_project_id - packet.net project id
• TF_VAR_ssh_key_path - path to SSH key (optional)

Script accepts one of two parameters:

• install - provision instance
• destroy - cleanup

Example usage:

PACKET_AUTH_TOKEN="..." ./hack/packet-provision.sh install

Warning! Script doesn't clean after itself (doesn't run destroy by default) so invoker is responsible for cleaning resources after provisioning them.

Currently we hard code reference to the image which we want to use by using a commit id from master branch of paulfantom/packet-image repository. This is done by setting user_data parameter in hack/prebuild/main.tf:

user_data        = "#cloud-config\n#image_repo=https://github.com/paulfantom/packet-image.git\n#image_tag=3a3f1eb378f660b335a68b79f3af303380462652\nssh_pwauth: True"
