#CDK flow:

• Create a typescript project
• Create an App (extends cdk.App)
• Create one or more stacks(children of App in CDK terms)
• Each stack can have multiple resources like S3 bucket etc.
• To get a list of stacks:
  • cdk ls -l
• To generate CFN template, use CDK toolkit command
  • cdk synth <stackName>
    • You’ll see the template as the output in terminal
• To deploy your CDK app:
  • cdk deploy
    • This command invokes calls to Cloud formation service and creates/updates stacks using the default credentials & region in your machine
    • Couldn’t see the template getting uploaded in an S3 bucket
• To assume a role from the Sandbox account:
  • We need to set some AWS environment variables to force CDK to use these env vars instead of the default profile from ~/.aws/credentials or ~/.aws/config
  • Pre-requisites:
    • A role role/AdminRole exists in your sandbox account that can be assumed by your default credentials
    • You've exported your sandbox account id with:
      • export AWS_ACCOUNT_ID=<Sandbox account id>
  • Execute the following:
    • source ./assume-role.sh
      • All the required env vars should have been exported
      • Check by executing: env | grep AWS
  • Now, all cdk commands would use the temporary credentials exported as env vars
  • Execute cdk commands as you would normally.
