Hi@akhtar,

To install packages in a docker container, the packages should be defined in the Dockerfile.

If you want to install packages in the Container, use the RUN statement followed by exact download command .

$ RUN pip install <package name > //IN Windows
$ RUN apt-get install <package name > //in Ubuntu
$ RUN yum install <package name> //CentOS/RHEL

You can update the Dockerfile with latest list of packages at anytime and build again to create new image out of it.

Hope this will help.
