Clear dockerfile cache

Hi, I was trying to integrate sleep command before running the source for the internal DNS Resolver to setup. But it seems like it's still using the cached CMD command instead of the newly replaced ENTRYPOINT. Any ways to clear the cache?

Solution:

"start": "sleep 3 && <regular start command here>"

more often than not this isnt a cahing issue, are you sure you dont have the start command set elsewhere?

Nowhere else other than after the sleep

FROM node:20.3-alpine

# Install Dependencies
COPY package.json ./
RUN npm install

# Build Source
COPY . .
RUN npm run build

# Start
#CMD ["npm", "start"]
ENTRYPOINT [ "./runner.sh" ]

FROM node:20.3-alpine

# Install Dependencies
COPY package.json ./
RUN npm install

# Build Source
COPY . .
RUN npm run build

# Start
#CMD ["npm", "start"]
ENTRYPOINT [ "./runner.sh" ]

# Waiting for Railway DNS Resolver
echo "Waiting for Railway DNS (10s)..."
# Sleep for 10 seconds (railway internal DNS load time)
sleep 10
# Run the command
npm start

# Waiting for Railway DNS Resolver
echo "Waiting for Railway DNS (10s)..."
# Sleep for 10 seconds (railway internal DNS load time)
sleep 10
# Run the command
npm start

Can also confirm it's not executing the runner.sh since the log did not echo the message.

what is getting printed then?

The Big E in Math -> ΣOP•13mo ago

Just the npm start logs as if I were using the old dockerfile

Brody•13mo ago

can you check to make sure you don't have a start command set in the service settings, a railway.json or a Procfile, or even an environment variable that sets the start command

The Big E in Math -> ΣOP•13mo ago

Just confirmed start cmd is empty. I don't have any railway/Procfile config or env that touches startup param.

Brody•13mo ago

are you deploying from the correct branch?

The Big E in Math -> ΣOP•13mo ago

yup, all changes are merged into main before being pull by railway.
