Install Podman for Cortex XSOAR.

When installing a new server or engine on RHEL 8 or later, the shell installer configures Podman automatically. There are some cases, however, where you might need to install Podman manually:

  • When using an installation method other than the shell installer (e.g. an RPM package) on RHEL 8 or later.

  • When the shell installer did not successfully install Podman.

  • When you want to migrate from Docker to Podman, for an existing Cortex XSOAR server or engine.


  • This procedure is intended for RHEL 8 or later. It may not work for other operating system types.

  • Do not use NAS storage for the $HOME directory. The directory needs to be a local directory for Podman to work.

  1. For RHEL 8, install Podman by typing the following commands:

    • sudo yum -y install slirp4netns fuse-overlayfs

    • sudo yum -y module install container-tools

    For RHEL 9 or later, install Podman by typing the following command:

    • sudo yum -y install slirp4netns fuse-overlayfs podman

  2. Run the following commands:

    • sudo touch /etc/subuid /etc/subgid

    • sudo mkdir -p /home/demisto

    • sudo chown demisto:demisto /home/demisto

  3. Configure the unqualified-search-registries used by Podman.

    Podman by default uses the fedoraproject.org, redhat.com, centos.org, and docker.io unqualified search registries. Since Cortex XSOAR images use only the docker.io registry, you can speed up download times for container images by setting unqualified-search-registries to just docker.io.

    1. Create or edit the /home/demisto/.config/containers/registries.conf config file.

    2. In the file, set the following:

      unqualified-search-registries = ['docker.io']


    If you edit the file with the root user, make sure to set the demisto user as file owner by running chown demisto:demisto /home/demisto/.config/containers/registries.conf

  4. Change the subuids and subgids by running the following command:

    sudo usermod --add-subuids 200000-265535 --add-subgids 200000-265535 demisto

  5. Migrate existing containers to Podman by typing the following command:

    sudo sh -c "cd /; runuser -u demisto -- podman system migrate"

  6. Set the net.ipv4.ping-group-range, by typing the following commands:

    • sudo sh -c "echo 'net.ipv4.ping_group_range=0 2000000' > /etc/sysctl.d/demisto-ping.conf"

    • sudo sysctl -w "net.ipv4.ping_group_range=0 2000000"

  7. As root user, edit one of the following config files:

    • Server:


    • Engine:


  8. Change the "container.engine.type": "docker" to "podman".

    If this line does not exist, add the following line to the file:

    "container.engine.type": "podman"

       "Server": {
                    "HttpsPort": "443",
                    "ProxyMode": true
            "container": {
                                    "engine": {
                                            "type": "podman"
            "db": {
                    "index": {
                            "entry": {
                                    "disable": true
  9. If the engine or server is running, restart the service.

    • Server: sudo systemctl restart demisto

    • Engine: sudo systemctl restart d1
