Usage

For Azure, generate a service principal:

az login
az ad sp create-for-rbac --sdk-auth

For AWS, go to IAM Management console, and generate an Access Key for your user in the Security Cretendials tab.

For DigitalOcean, go to API and generate a Personal access token.

For Google Cloud Platform:

Create a project, for example my-blockform. If the name is not long enough, google will append some random string that you will need to export in the next steps.
In API and Services, enable the Compute Engine API for this project.
In API and Services, go to the Credentials tab and generate an Account Service Key as a JSON file for the Compute Engine default service account.

Set environment variables:

export AZURE_TENANT_ID="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
