The document introduces Podman, a daemonless container engine designed for developing, managing, and running containers, particularly in cloud environments and Kubernetes microservices. It highlights its benefits, such as security and rootless operation, and provides installation guidance, usage tips, and community engagement opportunities. A real-world use case is presented to demonstrate Podman's effectiveness in local development workflows.
Power Up with Podman
- 2. 2 Curious about containers beyond Docker? There’s a new generation of containers on the scene, Podman! Supporting secure, rootless containers for Kubernetes microservices, it was designed and built with the cloud in mind. Benefitting from the lessons learned out in the open from Docker, this next generation of containers will quickly become a trusted daily driver in your dev workflow. Covering what you need to know as an end-user from the UI to the backend, sharing a real world use case leveraging Podman for open source observability workshops https://o11y-workshops.gitlab.io. Paige will share how Podman and the adorable seal mascots Caitlín, Maighréad and Róisín have transformed her local development!
