This gist is for reproducing keycloak/keycloak#43194
I built the Dockerfile with 3 sets of parameters, matching 26.2.3 with tag 260203, 26.3.5 with tag 260305, and 26.4.0 with tag 260400. Control which Dockerfile tag is used in CloudFormation with parameter overrides, like --parameter-overrides ImageUrl=public.ecr.aws/d4y1q9n5/keycloak-only-intelligentrxcom:260203
Steps for deploying each CloudFormation template are below. I did:

Deployed 26.2.3 (worked)
Updated by deploying with 26.3.5 (failed, and had to fix keycloak-only.yml)
Updated by deploying with 26.2.5 aws cloudformation deploy --template-file ./keycloak-only.yml --stack-name KeycloakOnly --capabilities CAPABILITY_NAMED_IAM --parameter-overrides ImageUrl=public.ecr.aws/d4y1q9n5/keycloak-only-intelligentrxcom:260205 (success)
Updated by deploying with 26.3.5 `aws cloudformation deploy --template-file ./keycloak-only.yml --stack-name KeycloakOnly --capabilities CAPABILITY_NAMED_IAM --parameter-o
