In this we video we introduce Podman Containers which is a major domain of the RHCSA 9 exam. Podman is a container management system similar to Docker but without the need of a service. We show how you can gain the knowledge for the exam and have fun with containers too
We install Podman, manage images and containers. We then look at running containers as a service, creating images from a container file and running systemd in containers. The sample Dockerfile is shown here:
FROM registry.fedoraproject.org/fedora:33
RUN yum -y install httpd; yum clean all; systemctl enable httpd;
RUN echo "Successful Web Server Test" | tee /var/www/html/index.html
RUN mkdir /etc/systemd/system/httpd.service.d/; echo -e '[Service]\nRestart=always' | tee /etc/systemd/system/httpd.service.d/httpd.conf
EXPOSE 80
CMD [ "/sbin/init" ]
