docker, nodejs: node not found error

Question

(on Ubuntu 16.04 and Docker 1.13)

When I run my dockerfile that tries to run my server.js, I get an error:

sh: 1: node: not found

I did some research and the name node and nodejs got changed because of package conflicts and is causing the error; however, when I switch to nodejs-legacy is doesn't work. What is causing the issue?

error with nodejs

error with nodejs-legacy

Make sure to have a comma in between the CMD command array

CMD ["node", "server.js"] 

instead of

CMD ["node" "server.js"]
