This procedure is intended for RHEL 8 or later. It may not work for other OS types.
Note
Do not use NAS storage for the $HOME directory. The directory needs to be a local directory for Podman to work.
Install Podman with related packages by typing the following commands:
sudo yum -y install slirp4netns fuse-overlayfs
sudo yum -y module install container-tools
Run the following commands:
sudo touch /etc/subuid /etc/subgid
sudo mkdir -p /home/demisto
sudo chown demisto:demisto /home/demisto
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.Create or edit the
/home/demisto/.config/containers/registries.conf
config file.In the file, set
unqualified-search-registries = [“docker.io”]
.
Note
If you edit the file with the
root
user, make sure to set thedemisto
user as file owner by runningchown demisto:demisto /home/demisto/.config/containers/registries.conf
Change the
subuids
andsubgids
by running the following command:sudo usermod --add-subuids 200000-265535 --add-subgids 200000-265535 demisto
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"
As root user, edit one of the following
config
files:Server:
/etc/demisto.conf
Engine:
/usr/local/demisto/d1.conf
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
