Executions

Get required packages and compile typescript to js.

npm install
npm run build

---

Bootstrap once per AWS account per region.

make bootstrap

---

Synth:

make synth

---

Diff:

make diff

---

Deploy:

make deploy

# You may need to press 'Y' if cdk involves creating IAM resources.

You will see the spot instance id after couple minutes. Then you can have an ssh connect to the new created spot instance:

./ec2-connect.sh {your_instance_id}

Destroy:

Normally you don't need to destory it, but it's an option.

make destroy

Clean:

If you are using multiple AWS/IAM accounts, you may need to clean up the cdk context (which is generated by cdk synth).

make clean
