Lessons learned adopting the Podman toolset.
A hands-on demonstration of lessons learned migrating from other container build tools to the RHEL container ecosystem. We aim to explore a set of command-line tools that are able to operate without a container daemon, and namely: Buildah, Podman, Quay and Skopeo.
We will discuss a new set of open-source Container Management Tools starting from a hands-on demonstration. In a nutshell, Buildah builds, Podman runs, Skopeo transfers container images and Quay provides private and public container registries.
Moreover, we will take a look at best practices for building images that can easily be integrated into a CI/CD Pipeline and vulnerability scanning with Clair, thus replacing previous build tools in workflows.
- Understand the impact of SELinux, namespaces and cgroups.
- Move from docker-compose to Podman pods.
- Build container images for OpenShift Container Platform.
- Develop and test Ansible Playbooks / Roles with Podman.
