Red Hat OpenShift Development I: Introduction to Containers with Podman
Podman Compose is an open source tool to run Compose files.
Podman Compose removes the need to run the Podman service that provides the API socket, to save resources and to provide a more native and lightweight solution.
Podman Compose translates Compose files into Podman CLI commands.
The
podman generate kubecommand generates a Kubernetes YAML file from existing Podman containers, pods, and volumes.The
podman play kubecommand reads the Kubernetes YAML file, and then recreates the defined resources in a Kubernetes or an RHOCP cluster.You can use Podman Compose to quickly build a stateful, multi-container environment for your applications.
You can restrict communication between specific containers by defining additional networks for the pod and then defining the network settings.
You can use Podman Compose to approximate a production environment on your local machine by providing applications, databases, or cache systems configuration in a single file.
You can use Podman Compose to execute your application and database containers in isolated local environments.
Using Podman Compose in a production environment is not recommended, because it does not support advanced features that you might need in a production environment, such as load balancing and distributing containers to multiple host machines, or nodes. Instead, use Kubernetes or RHOCP for a production container orchestration solution.
