While trying setting EMBER_CLI_PROD_ASSETS to 1, I’m getting the following at the time of precompiling assets (version 2.9.0.beta2 commit: d2de058ff51f204fcf85c86a00750a59505af3bb):
yarn run v1.22.17

No success after a rebuild of the instance. I’m more looking for what is causing the uv_os_get_passwd call, or more generally about what is causing this error, does this expect any specific user in the system/setting to be set?
How exactly are you running the Discourse image? Are there any extra flags for security?
Following this trace, the problem is that the Ember-CLI build is failing, and while trying to print the error, it is throwing yet another exception and masking the real one.
Can you go inside the Discourse image and try:
node
const os = require('os');
os.userInfo().shell
Intersting, this is what I’m getting when executing your suggestion (and makes total sense if the intention is to access any internal library system with a random user other than root):
node
Welcome to Node.js v16.13.2.
Type ".help" for more information.
> const os = require('os');
undefined
> os.userInfo().shell

We’ve been using a containerized solution based in OpenShift, in which Discourse is running with a random user id. No issues so far, approach very similar to the official install guide.
It’s certainly that we can bypass this issue by setting EMBER_CLI_PROD_ASSETS to 0, assets are precompiled as in the old days, but sooner than later, if your plans are to move into this direction, can pose a real problem for this kind of solutions if the current precompiling process is abandoned.
So a couple of questions here:
Do you have an ETA about abandoning (if that’s the case) precompiling assets the old way?
Is there any way to access the os machinery on a different way, or consider a different approach, so that containerized solutions with random user id’s can still work?
Many thanks for looking into this, much appreciated.
We are removing that EMBER_CLI_PROD_ASSETS in the next few weeks.
We are not using that directly, but a dependency, of a dependency, of a depedency… I think it’s a weird call too, but it’s not something we have much control over.
Yes, exactly. We’ve been slowly releasing this new asset pipeline over years, so we can track what the EmberJS project recommends and be less of a snowflake. We are in the final phase of the rollout already.
Just for the record, and whether it is useful for somebody around. There is at least a way to make ember cli working as expected with a random uid, and it is ensuring that the assigned random uid has an entry under /etc/passwd at the time of running the rake assets:precompile operation.
Something like:
if [ `id -u` -ge 10000 ]; then
cat /etc/passwd | sed -e "s/^discourse:/builder:/" > /tmp/passwd
echo "discourse:x:`id -u`:`id -g`:,,,:/home/discourse:/bin/bash" >> /tmp/passwd
cat /tmp/passwd > /etc/passwd
rm /tmp/passwd
fi
yarn run v1.22.17
$ /discourse/app/assets/javascripts/node_modules/.bin/ember build -prod

I have also noticed that this operation is quite expensive, by consuming almost 2GB of ram just for precompiling
