I am using the old version of the template (with v3.3.6), and I wanted to try 2 things: create a new project, and then potentially "update" my existing project.
Following the direction verbatim didn't go well:

So I opened VSCode, created a new PHP 8.5 devcontainer to bootstrap the installer and tried again in it, but I got Docker and Node missing errors, so I added them to the config:
{
"name": "PHP",
"image": "mcr.microsoft.com/devcontainers/php:3-8.5-trixie",
"features": {
"ghcr.io/devcontainers/features/node:2": {},
"ghcr.io/postfinance/devcontainer-features/docker-out:1": {}
}
}
Now downloading and running it again worked (gave some build error but completed):
vscode ➜ /workspaces/temp1 $ ./api-platform my-app --framework=symfony --with-docker --with-pwa --with-admin

[OK] Project created successfully at /workspaces/temp1/my-app
Next steps:
cd my-app/api
docker compose up --wait
open https://localhost
cd ../pwa
pnpm dev
open http://localhost:3000
CORS is pre-configured to allow requests from localhost.
cd ../admin
npm run dev
open http://localhost:5173
"my-app" was created

Then from outside the bootstrap devcontainer (from WSL) docker compose up --wait, and API is up on https://localhost 🎉.
However, I see several things missing from the previous template to continue:
compose.yaml doesn't include the "pwa" service config, and I don't see a Dockerfile in the pwa/admin folders.
compose.yaml also doesn't include the "database" (postgres) service config.
- I see that symfony-docker added https://github.com/dunglas/symfony-docker/tree/main/.devcontainer, but the created api-platform project doesn't have the ".devcontainer" folder. It would be greatly appreciated if it were included.
- No Helm chart, although I can make one myself once
compose.yaml has everything. I have a similarly structured Helm project to the old API-platform Helm that also used Bitnami. I added CloudNativePG support to it and an option to migrate from the Bitnami config to the CNPG config. I can share if there is an interest.
