Mount a container filesystem

You can share host directories or devices with a container by mounting them. For example, mounting /dev/log allows the container to write logs directly to the host’s system journal.

Before you begin

  • The container-tools meta-package is installed.

Procedure

  1. Run the container named mysyslog: 
    # podman run -dt --name=mysyslog registry.redhat.io/rhel10/support-tools
  2. Run the podman mount command to mount a working container root filesystem in a location accessible from the host. For example, mount the mysyslog container: 
    # podman mount mysyslog
     
    /var/lib/containers/storage/overlay/990b5c6ddcdeed4bde7b245885ce4544c553d108310e2b797d7be46750894719/merged
  3. Display the content of the mount point using ls command: 
    # ls /var/lib/containers/storage/overlay/990b5c6ddcdeed4bde7b245885ce4544c553d108310e2b797d7be46750894719/merged
     
    bin  boot  dev  etc  home  lib  lib64  lost+found  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
  4. Display the OS version: 
    # cat /var/lib/containers/storage/overlay/990b5c6ddcdeed4bde7b245885ce4544c553d108310e2b797d7be46750894719/merged/etc/os-release
