Would be nice if it provided a sample Dockerfile.
My Dockerfile is:
# syntax = docker/dockerfile:1.2
FROM node:18
RUN npm install -g pnpm@8.6.5
WORKDIR /app
COPY pnpm-lock.yaml .
COPY patches ./patches
RUN pnpm fetch
COPY . .
RUN pnpm install --frozen-lockfile --prefer-offline
RUN --mount=type=secret,id=_env_local,dst=/app/.env.local pnpm run build
CMD pnpm start
How do I know on what port to expose the service?
How do I make the mounted secrets available to CMD?
Also, the build/deploy logs exclude docker run command from the logs:
Jul 3 08:16:50 AM ==> Cloning from https://github.com/lucgagan/rayrun-blog...
Jul 3 08:16:51 AM ==> Checking out commit 8730772a142a2fcbe0b22c8c864d1b1058fb7258 in branch main
Jul 3 08:16:54 AM #1 [internal] load .dockerignore
Jul 3 08:16:54 AM #1 transferring context: 126B done
Jul 3 08:16:54 AM #1 DONE 0.0s
Thus further obscures the debugging experience.
The service itself appears to be crashing (?) in a loop:

Not clear why next start is run multiple times without an error in between.
