Running commands

The scripts are kept in the src/deploy folder of this repository. The two commands yarn synth and yarn deploy will be used to run those scripts.

Deploy with CDK

• yarn synth -a "tsx src/main.ts --pi <google cloud project id>
• yarn deploy vm-instance k0s-cluster -a `tsx src/main.ts --pi <google cloud project id>

The deploy command do run synth, however it is easier to verify the command by the synth separately.
