RUN command in Dockerfile not persisting from container to container

Question

I am running yo in a Docker container and in my Dockerfile, I have the command RUN echo no | yo doctor. When yo runs for the first time, it asks for an answer to:

==================================================================== We're constantly looking for ways to make yo better! May we anonymously report usage statistics to improve the tool over time? More info: https://github.com/yeoman/insight & http://yeoman.io ==================================================================== (Y/n)

Every time, I create a new container, yo is asking me the same question again. Since each container is being built using the same image and I am running echo no | yo doctor in my Dockerfile shouldn't it prevent yo from asking the question again?

Whenever I see a RUN using pipe, I try that command in a subshell (sh -c)

RUN sh -c 'echo no | yo doctor'

If it does not work, another workaround would be to include that command in a script, COPY the script and RUN it.

This doesn't fix the problem. The command runs fine when I run docker build. When I create a new container using docker run, yo still asks that question.

@Shan What is your ENTRYPOINT and CMD? What is executed on docker run?
