Build exited too early in Docker

[florian-milky]

Describe the bug In our CI we build storybook in a docker container to deploy it later. Today, one of the builds exited too early, and some files were missing like iframe.html:

#18 117.8 info => Manager built (1.85 min)
#18 DONE 142.3s

Normally it logs more lines:

#18 111.1 info => Manager built (1.73 min)
#18 138.7 info => Preview built (2.2 min)
#18 140.8 info => Output directory: /usr/src/dist/storybook
#18 DONE 141.1s

To Reproduce Can't reproduce really, this is for the record

System Docker node:14-alpine

Additional context Re-launched the build without changing anything and it worked fine

Hi @florian-milky, do you mind sharing your Dockerfile or any information on how the build runs? I know Docker do some image optimisation and may skip some parts and reuse cache in some case.

[florian-milky]

There is a bunch of stuff there but the relevant part is:

# syntax=docker/dockerfile:1.2
FROM node:14-alpine AS builder
...
RUN npm run build:storybook

package.json

"build:storybook": "build-storybook -o ./dist/storybook -s ./public,.storybook/public --quiet",

Our docker is configured with cache but in that case it triggered the storybook build, something went wrong at the end (I supposed) and it just continued

[alk-mandrianarijaona]

I guess the --quiet swallows all errors, removing it (at least temporary) may help see the root cause

[florian-milky]

Hmm I thought about that but why is it even logging at all then? I'll look into it, thanks!

[alk-mandrianarijaona]

I believe it should log at least the important errors

@florian-milky did you ever solve this? I think I am seeing the same thing. Removing --quite doesn't seem to reveal anything obvious (at least, to me).

When I build on my host/Mac, it works.

In the Docker container, it's only generating a few files.

I think I got it solved by boosting my Docker’s memory/disk allocation:

@florian-milky did you ever solve this?

It was a one-time thing for me. Felt like a glitch

[florian-milky]

Running into this issue again. Removing --quiet did not help. No error or warning is shown. It just stops after the manager has been built.

Updated to storybook 6.5.13 and it is gone again
