I found the image that's running via kubectl describe and ran it in a shell. It ought to be running this (from the Dockerfile):
...
ENTRYPOINT ["node", "--max-old-space-size=4096", "--enable-source-maps"]
CMD ['node_modules/.bin/rollup','-cw']
So in the shell I ran:
❯ dsh myregistry/project/server:R4SUGQt
+dsh:1> docker run --rm -it --entrypoint sh myregistry/project/server:R4SUGQt -c '{ command -v zsh && exec zsh -il ;} || { command -v bash && bash -il ;} || { command -v ash && ash -il ;}'
/bin/ash
06884c20d5cc:/app# node --max-old-space-size=4096 --enable-source-maps node_modules/.bin/rollup -cw
And it works perfectly. So where's that error stemming from? All the paths in the stack trace internal (internal/modules/...) not from my script or rollup.
I'm using node:alpine as my base image which is currently on Node v14.11.0.
Running it directly
docker run --rm myregistry/project/server:R4SUGQ
does reproduce the error.
Running
docker run -it myregistry/project/server:R4SUGQt node_modules/.bin/rollup -cw
Works fine... is there something wrong with my CMD syntax?
CMD ['node_modules/.bin/rollup','-cw']
It was the single quotes I used in the CMD.
Found this reddit post after the fact: https://www.reddit.com/r/docker/comments/9wn5gw/be_aware_of_the_quotes_in_your_dockerfile/
What a waste of time... leaving this question here in case someone else hits a similar error, maybe it'll be Googlable for them.
