+以下に `myapp` をすべて `hello-world` に書き換えて実行した結果を示します

+COPY entrypoint.sh /usr/bin/
+RUN chmod +x /usr/bin/entrypoint.sh
+ENTRYPOINT ["entrypoint.sh"]
+EXPOSE 3000
+# Start the main process.
+CMD ["rails", "server", "-b", "0.0.0.0"]
+```
+`entrypoint.sh`:
+```bash
+#!/bin/bash
+set -e
+# Remove a potentially pre-existing server.pid for Rails.
+rm -f /hello-world/tmp/pids/server.pid
+# Then exec the container's main process (what's set as CMD in the Dockerfile).
+exec "$@"
