What can be?

Hey Juan

Any chance you could share the Dockerfile and/or repo you’re deploying from? Having a look at your error it seems like the yarn.lock file is missing from the directory you’re deploying your app from.

Sure mate,

this is my dockerfile

# syntax = docker/dockerfile:1

# Adjust NODE_VERSION as desired
ARG NODE_VERSION=18.18.0
FROM node:${NODE_VERSION}-slim as base

LABEL fly_launch_runtime="Node.js"

# Node.js app lives here
WORKDIR /app

# Set production environment
ENV NODE_ENV="production"
ARG YARN_VERSION=1.22.19
RUN npm install -g yarn@$YARN_VERSION --force


# Throw-away build stage to reduce size of final image
FROM base as build

# Install packages needed to build node modules
RUN apt-get update -qq && \
    apt-get install --no-install-recommends -y build-essential node-gyp pkg-config python-is-python3

# Install node modules
COPY --link .yarnrc.yml package.json yarn.lock ./
RUN yarn install --frozen-lockfile --production=false

# Copy application code
COPY --link . .

# Build application
RUN yarn run build

# Remove development dependencies
RUN yarn install --production=true


# Final stage for app image
FROM base

# Copy built application
COPY --from=build /app /app

# Start the server by default, this can be overwritten at runtime
EXPOSE 3000
CMD [ "yarn", "run", "start" ]

It looks like medusa starter has yarn.lock in gitignore: medusa-starter-default/.gitignore at master · medusajs/medusa-starter-default · GitHub

We default to basing your .dockeringore file on the contents of .gitignore.

Try removing the line yarn.lock from .dockerignore and deploying again.

Thanks fpor the help, that was the solution!
