Instructions to run CI tests in your own packet-net instances

1. Download terraform https://www.terraform.io/downloads.html
2. Get your API key by clicking in your user profile (top right corner) and pick "API Keys" https://app.packet.net/login
3. Create an API Key with read/write permissions and give a description, something like "CI private testing"
4. Store the private token as you will need it in the next steps
5. Go to the packet.net and pick or create a project ID
6. Generate your own SSH keys via ssk-keygen
7. Set the following env vars:

export TF_VAR_public_key_path="<SSH PUB KEY PATH>"
export TF_VAR_private_key_path="<SSH PRIV KEY PATH>"
export TF_VAR_metal_token="<TOKEN>"
export TF_VAR_metal_project_id="<PROJECT ID>"
# For europeans it's better to pick Amsterdam (ams1) or Toronto (yyz1)
export TF_VAR_metal_location="ams1"
export TF_VAR_metal_plan="c1.small.x86"

8. terraform init
9. terraform apply
10. After the VM is up and running you can check its IP with terraform show
11. SSH in to the public IP with ssh -i <ssh-key-path> root@<publicIP>
12. Checkout to the branch that you want to test git checkout <my-faulty-branch>
13. Run screen which will create a new terminal, this is helpful as you can leave your terminal while tests are running and come back again afterwards.
14. Enter the test directory with cd test
15. Run the ginkgo command to initialize the tests, for example: INTEGRATION_TESTS=true K8S_VERSION=1.14 ginkgo --focus="K8s" -v -- --cilium.showCommands --cilium.holdEnvironment=true
16. Once tests are running and if you are running screen, you can leave the terminal by typing CTRL+a+d, to resume again type screen -r
