I have converted a legacy react app from using Webpack 3 to use Next.js 12 and Webpack 5.
I am currently trying to deploy the project using Docker through bitbucket pipelines but when running next build
it gets stuck on 'Creating an optimized production build' and eventually runs out of memory and the build fails.
I am using the same Dockerfile setup from next.js example and the docker build runs perfectly on my local machine with the same steps.
Has anyone experience a similar issue? No errors or anything are shown during yarn install
or the build itself and I have outputStandalone set to true.

According to out of memory
error, you could try setting Node memory before yarn build
ENV NODE_OPTIONS=--max-old-space-size=4096

I did run into a similar issue with npm@7, due to https://github.com/npm/cli/issues/2011 / https://github.com/npm/cli/issues/3208 , rant intended.
A workaround was to increase the docker service memory limits from bitbucket-pipelines.yml (default is 1024 MB)
definitions:
services:
docker:
memory: 3072
or possibly even doubling the resources allocated for your step:
definitions:
services:
docker:
memory: 7128
pipelines:
default:
- step:
size: 2x
services:
- docker
script:
- docker build .
Beware that service resources are subtracted from those allocated for your step, so the step script would run on decreased memory.
Also remember you will be charged x2 for your size: 2x
steps.
