These are the steps I run to turn preprod back on and verify. Once oidc is up, you can run the node.js, springboot, and ui playbooks in parallel (I've fixed the overwriting problem with generating .env files).
ap-preprod azure-start.yml
ap-preprod services-nodejs.yml -l oidc
ap-preprod services-nodejs.yml -l oidc -t init_pm2
ap-preprod services-nodejs.yml -l non_oidc
ap-preprod services-nodejs.yml -l non_oidc -t init_pm2
ap-preprod services-spring.yml
ap-preprod ui.yml
