Hello, initially I had deployed with nix, but I created Dockerfile, build and deploy work, but the custom pre-deployment command does not launch (its migration with adonis), when I had used nix build, pre deploy command worked. I will need add command pre deploy in Dockerfile ?

Hi,
You can integrate the command directly into the container startup process so it runs before the actual application starts.
Example:
Dockerfile
FROM node:20
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 3333
# Start with migration
CMD ["sh", "-c", "node ace migration:run --force && node server.js"]
With this setup, when the container starts it will first run:
node ace migration:run --force
and then start the server.
This way, you don’t need any separate pre-deploy hooks on the hosting platform.

mbenfriham, you can add the pre-deploy command on the Railway dashboard itself: https://docs.railway.com/guides/pre-deploy-command
