# Loomio — Notes

## Custom startup command must reproduce ENTRYPOINT setup steps

Loomio's Docker image uses `docker_start.sh` as its ENTRYPOINT, which copies
`client3-build/` → `public/client3/` before starting Rails. Overriding the entrypoint with a
direct Rails command skips this step, leaving `client3/` unpopulated and causing 500 errors on
all routes serving the SPA.

**Fix**: reproduce the copy step explicitly in the deployment `command:`:

```yaml
command: ["/bin/bash", "-c"]
args:
  - |
    set -e
    mkdir -p /loomio/public/client3
    cp -r /loomio/client3-build/* /loomio/public/client3/
    bundle exec rake db:migrate db:seed
    bundle exec thrust puma -C config/puma.rb
```

**General rule**: whenever you override `command:`, inspect the image's `ENTRYPOINT`/`CMD`
(via `docker inspect` or the Dockerfile) and reproduce any required setup steps.
