Earlier this week I started seeing failures on my Docker builds with a rather cryptic message: sh: 1: node: Permission denied. This was really strange, because I did not change anything significant enough to cause this error. Example of failing logs:
For netlify-cli:

The error message looks slightly different in each case.
What I think is the problem: In my Docker container, I'm using Volta for node/yarn version management. And for the volta install command it internally uses npm install --global, which does not like to run when the script is executed as root.
So the solution was to add following line to my Dockerfile just before the volta install command:
RUN npm set unsafe-perm true
