12장. Podman을 사용하여 컨테이너를 OpenShift로 포트

프로세스

1. 연결된 모든 Pod 및 컨테이너를 나열합니다.

   $ podman ps -a --pod
   CONTAINER ID  IMAGE                                       COMMAND    CREATED                 STATUS                     PORTS  NAMES               POD
   5df5c48fea87  registry.access.redhat.com/ubi10/ubi:latest  /bin/bash  Less than a second ago  Up Less than a second ago         myubi               223df6b390b4
   3afdcd93de3e  k8s.gcr.io/pause:3.1                                   Less than a second ago  Up Less than a second ago         223df6b390b4-infra  223df6b390b4

   podman generate 명령은 컨테이너에 연결할 수 있는 LVM(Logical Volume Manager) 논리 볼륨 또는 물리 볼륨이 반영되지 않습니다.

3. mypod.yaml 파일을 표시합니다.

   $ cat mypod.yaml
   # Generation of Kubernetes YAML is still under development!
   #
   # Save the output of this file and use kubectl create -f to import
   # it into Kubernetes.
   #
   # Created with podman-1.6.4
