A gradual start of exploring what it could look like to migrate an existing Java application from AWS ElasticBeanstalk to AWS EKS.

Steps

setup

First, putting in place some helpful information used in the various AWS CloudFormation Stacks / CLI calls made.

touch account.env
echo AWS_ACCOUNT_ID=YOUR_AWS_ACCOUNT_ID >> account.env
echo EMAIL_ADDRESS=YOUR_EMAIL_ADDRESS >> account.env

Then, to ensure we have all the system requirements and the project setup!

# checks to ensure you have everything required
make preflight
# Then, resolve any errors based on the outputs then re-run until no errors remain

# If no errors, proceed
make bootstrap

beanstalk via cloudformation

make deploy-infra-beanstalk

ecs via cdk

make deploy-infra-ecs

eks via cdk

make deploy-infra-eks

eks - with some cdk8s

make deploy-infra-eks-extra

Cleanup

make cleanup
