External crypto packages not working, others do

That is “sadly” not how Docker works. You have to use the currently running container and then create a new image from it. You can find some information about how that can e done here:

How to Create a Docker Image From a Container | Scalyr

Anyway, that is still dirty. The best is to create a custom Docker image via a Dockerfile and use the n8n image as a base. Here is one of many examples in the forum where somebody does something like that:

External CLI tools in n8n

Now it works. I needed to install peer dependencies on my own. So I added this to the end of the Dockerfile as well. The build works without errors. This is what my dockerfile looks like now: FROM n8nio/n8n RUN apk --update add python RUN apk --update add make RUN apk --update add g++ RUN npm install -g n8n-nodes-suitecrm --unsafe RUN npm install -g install-peerdeps thank you so much for your help and input!
