Quick intro into dealing with Podman

creating containers & pods

  • create a container sample httpd server:

    podman run -dt -p 8080:8080/tcp -e HTTPD_VAR_RUN=/var/run/httpd -e HTTPD_MAIN_CONF_D_PATH=/etc/httpd/conf.d \
                -e HTTPD_MAIN_CONF_PATH=/etc/httpd/conf \
                -e HTTPD_CONTAINER_SCRIPTS_PATH=/usr/share/container-scripts/httpd/ \
                registry.fedoraproject.org/f29/httpd /usr/bin/run-httpd

  • create an empty pod

  • create a pod including a container running an app

sudo podman run --cap-add IPC_LOCK --rm docker.io/library/vault -p 8200:8200 --pod new:vault

list

  • list containers:

sudo podman ps

  • list all containers:

sudo podman ps -a

  • list pods and included containers:

sudo podman ps -a --pod check the output for your container running vault and pick its container-id

check

  • inspect container

sudo podman inspect <<containerid>>

  • get logs

sudo podman logs <<containerid>>

managing pods

  • add a container to a pod:

  • stop a container in a pod:
    sudo podman stop <<container-id>>
  • stop a pod:
    sudo podman pod stop <<pod-id>>
  • start a pod again: sudo podman pod start <<pod-id>>
  • delete a pod: sudo podman pod rm <<pod-id>>
