Getting started

On the provisioner

• Then run:

./create_images.sh

• Now create the hardware entry

./generate.sh
docker cp hw1.json deploy_tink-cli_1:/tmp/

docker exec -ti deploy_tink-cli_1 tink hardware push --file /tmp/hw1.json 

• Now create a workflow for the entry with the template ID

• Then create the ubuntu.tmpl template with tink-cli

docker cp ubuntu.tmpl deploy_tink-cli_1:/tmp/

docker exec -ti deploy_tink-cli_1 tink template create -n 'ubuntu' -p /tmp/ubuntu.tmpl

• Now create a workflow

# See the output from Terraform
export MAC="08:00:27:00:00:01"

# See "tink template list"
export TEMPLATE_ID="57342d5c-9fd9-4c09-b45b-cd6a129961a9"

docker exec -ti deploy_tink-cli_1 tink workflow create -t "$TEMPLATE_ID" -r '{"device_1": "'$MAC'"}'

• Copy image.img to the web root of nginx, if you don't have the image see the Packer heading on how to build the image.

You should see image.img in: /vagrant/deploy/state/webroot/misc/osie/current/ from within the Vagrant provisioner VM.

• Boot up the worker

To run again, you'll need to:

• Create another workflow (run the steps above tink workflow create)
• Then start a fresh VM: vagrant destroy worker --force && vagrant up worker

Appendix

1. Make an image with Packer and Virtual box (see below)

2. Convert the image to raw format

VBoxManage clonehd ./packer-ubuntu-20.04-live-server-1593009318-disk001.vmdk image.img --format raw

3. Move the image to /misc/osie/current/ <- wherever the webroot is for Nginx
