Hmm interesting, let’s see:

So discourse’s package.json is requesting 13.0.1, ember-cli’s own package.json [requests 12.0.4](https://github.com/ember-cli/ember-cli/blob/53b5dcc903abc96a3d66f16804fa56b85e32c101/package.json#L104-L105), and `markdown-it-terminal` [requires 8.4.2](https://github.com/trabus/markdown-it-terminal/blob/3afe70d8a0d565e3107e0a96b5a728876589dbb7/package.json#L35).

Anyway, in theory this should all be invisible. Discourse itself is asking for 13.0.1, and so the version in `app/assets/javascripts/node_modules/markdown-it` should be 13.0.1. The other older versions will be made available to their respective parents.

Given that we’re not seeing this internally, and this is only happening for people with non-standard installs, I suspect we’re missing a `yarn install` somewhere in the two-container setup templates, and so the database container is booting up with the cached version of markdown-it from the base image 👀
