Hi, im trying to host a simple NodeJS app.
When running it. All ports I try are in use.
This is my Dockerfile:
FROM node:18.9.0
WORKDIR /app
ADD . /app
COPY . .
RUN npm install
RUN npm run build
EXPOSE 8080
CMD [ "node", "./index.mjs" ]
Fly IO config is default with also the app on port 8080.
No matter what port I try:
Error: listen EADDRINUSE: address already in use 127.0.0.1:8080
Also tried 0.0.0.0:8080 and ports 3000, 3030 and 1337.
Hi Elmar, could you please post the fly.toml configuration and the index.mjs code fragment responsible for starting the HTTP listener? You application should be accessible at <application-name>.fly.dev, it not clear why you try to access it at 127.0.0.1 and 0.0.0.0.
This is an error from the build logs when doing the health check. Im not trying to access the app from there. Its simply not deploying. When Fly tries to run the node app it says address is in use.

const app = express();
app.use(express.static('dist/client/'))
app.use(ssrHandler);
app.listen(process.env.PORT || 8080);
The configuration and code look correct. Haven’t you tried to destroy the application using 'fly destroy <application_name> and start deployment again?

Thanks for the log, probably there is something with setupListenHandle:
Could you try to run something simple as:
import express from 'express';
const app = express();
app.listen(8080)
app.get('/', (req, res) => {
res.send('Hello!')
})
I’m getting the same issue while deploying a nodejs app.
Can I get you to try:
mkdir demo
cd demo
npx --yes @flydotio/node-demo@latest
fly launch
fly deploy
