Running a docker image, produced from a Dockerfile, does not do anything

I use this Dockefile copied from here

#we are using ubuntu base image
FROM ubuntu:18.04
# installing requirements to get and extract prebuilt binaries
RUN apt-get update && apt-get install -y \
 xz-utils \
 curl \
 && rm -rf /var/lib/apt/lists/*
#Getting prebuilt binary from llvm 
RUN curl -SL https://github.com/llvm/llvm-project/releases/download/llvmorg-10.0.0/clang+llvm-10.0.0-x86_64-linux-gnu-ubuntu-18.04.tar.xz \
 | tar -xJC . && \
 mv clang+llvm-10.0.0-x86_64-linux-gnu-ubuntu-18.04 clang_10 && \
 echo ‘export PATH=/clang_10/bin:$PATH’ >> ~/.bashrc && \
 echo ‘export LD_LIBRARY_PATH=/clang_10/lib:$LD_LIBRARY_PATH’ >> ~/.bashrc
#start the container from bash
CMD [ “/bin/bash” ]

Then I run

docker build -t clang_10 .

It works. With the clang_10 image well created.

But then I run

docker run -it clang_10

Nothing happens! The console does not switch to a Linux prompt as expected. Where do things go wrong?

dockerfile docker

The problem is the types of quotes: Use " instead of “.

Change the last line from

CMD [ “/bin/bash” ]

to

CMD [ "/bin/bash" ]

change the CMD to CMD [ "/bin/bash" ] or ["/bin/sh"]
