My Docker file -

COPY . /app
RUN sudo chmod 777 -R /app
WORKDIR /app
ADD entry_point.sh /opt/bin/
RUN sudo chmod 777 /opt/bin/entry_point.sh
COPY start-selenium-standalone.sh /opt/bin/start-selenium-standalone.sh
RUN sudo chmod 777 /opt/bin/start-selenium-standalone.sh
EXPOSE 4444 5900 9515

**Command to build docker image**
docker build -f Docker/Dockerfile -t sel-test:1 .

**Command to run the image** 
docker run -d -p 4444:4444 -p 5900:5900 -v /dev/shm:/dev/shm sel-test:1

**Error I am getting -**
Error response from daemon: Container a9e0bb7f381584dd5e39dcd997640233835408ffdfe4e0e44108ddb7bb393cd0 is not running

Answer 1

Your container is exiting because there is nothing to run inside the container.

To see this, run the docker ps -a command and check the status of your container.

In order to run something inside the container use CMD in docker file to run bash inside the container whenever you use 'docker run'.
