docker run IMAGE /bin/bash does not work and return errors

Basically, I can’t run a container with /bin/bash, and it is not returning any errors. I can run it with:

sudo docker exec -it CONTAINER_NAME /bin/bash

and it works fine, I am able to get into the container and do stuff. However, the following does not work:

sudo docker run IMAGE-NAME /bin/bash

In the Dockerfile I have the following CMD command:

CMD [ "python3", "/opt/code/python-fire-server-base/main.py", "-v", "-H=0.0.0.0", "-p=9002", "-l=/tmp/python-fire-server-base.log", "-s", "/tmp/save/" ]

I know that the CMD is calling for a Python code, but previously (2-3 weeks ago), I was able to run the image created with this Dockerfile without issues using the run command. Now for some reason, it doesn’t work, and it doesn’t return any errors as well. I didn’t change the Dockerfile, only modified the underlying Python code.

What am I missing here?

Edit:
Dockerfile is

>Solution :

You forgot to allocate the pseudo-TTY:

sudo docker run -it IMAGE-NAME /bin/bash

this will overwrite the default CMD with /bin/bash.
