Modify ... Build the Docker image for the solver service

Description of the modifications

I followed the instructions on build solver container in these tutorial https://dyna.docs.pyansys.com/version/stable/getting-started/index.html#run-pydyna-server-in-a-docker-container. But in the step building docker image with the docker build -t dyna_solver_v04 . It get error messenger: process "/bin/sh -c yum -y install openssh-clients openssh-server bind-utils sudo python3 unzip &>/dev/null && yum clean all" did not complete successfully: exit code: 1 Does anyone meet these problems?

The root cause here is that the Dockerfile is built on top of CentOS 7, which has reached its end-of-life. With that, the package repositories that yum install uses have moved from mirror.centos.org to vault.centos.org.

The Dockerfile should be amended to either include the following statement [1]:

RUN \
  sed -i s/mirror.centos.org/vault.centos.org/g /etc/yum.repos.d/*.repo && \
  sed -i s/^#.*baseurl=http/baseurl=http/g /etc/yum.repos.d/*.repo && \
  sed -i s/^mirrorlist=http/#mirrorlist=http/g /etc/yum.repos.d/*.repo

or updated to be based on a newer base OS (e.g. RockyLinux 8).

The PyDyna devs would know which is the correct action in this case, I am transferring the issue to that repository.

Reopening because I think the Dockerfile should be fixed s.t. it works out of the box.
