Docker file giving error

FROM ubuntu

RUN "apt-get update && apt-get install -y moreutils"

CMD ["/bin/bash","-i"]

I created the above file and named it Dockerfile

To build the image,

sudo docker build -t test .

I don’t see a problem, do you??

Got it,

Removing " around parameter of RUN directive ran the script

but I don’t know why it didn’t build with " around

It doesn’t build with the citation marks because you do not use citation marks when you send a command to bash.
