See the solution below in Explanation.
Explanation:
Solution:
firewall-cmd --permanent --add-service=http
firewall-cmd --reload
firewall-cmd --list-services
Detailed Explanation:
* --permanent saves the rule.
* --reload applies it.
* --list-services verifies the active configuration.
* Firewalld remains the standard firewall interface in RHEL 10. ( Red Hat Documentation )

See the solution below in Explanation.
Explanation:
Solution:
dnf install -y httpd policycoreutils-python-utils
mkdir -p /webdata
echo "RHEL10 Web Server" > /webdata/index.html
sed -i 's/^Listen 80/Listen 8080/' /etc/httpd/conf/httpd.conf
semanage port -a -t http_port_t -p tcp 8080
firewall-cmd --permanent --add-port=8080/tcp
firewall-cmd --reload
systemctl enable --now httpd
systemctl restart httpd
ss -tulpn | grep 8080
Detailed Explanation:
* Apache defaults to port 80, so Listen 8080 changes the service port.
* SELinux must allow Apache to bind to 8080, which is done with semanage port.
* firewall-cmd opens the port externally.
* RHEL 10 documents firewalld as the standard firewall management interface and SELinux port
labeling for confined services. ( Red Hat Documentation )

Explanation:
Solution:
dnf install -y stratisd stratis-cli
systemctl enable --now stratisd
stratis pool create pool1 /dev/sdc
stratis filesystem create pool1 fs1
stratis filesystem list
Detailed Explanation:
* stratisd is the daemon and stratis-cli provides the command-line interface.
* A Stratis pool is created from a block device.
* The Stratis file system is then created inside that pool.
* RHEL 10 documents Stratis as an available volume-managing file-system layer. ( Red Hat
Documentation )

Explanation:
Solution:
dnf install -y nfs-utils
mkdir -p /srv/nfs/projects
echo "/srv/nfs/projects 192.168.50.0/24(rw,sync)" > > /etc/exports
exportfs -rav
systemctl enable --now nfs-server
firewall-cmd --permanent --add-service=nfs
firewall-cmd --reload
exportfs -s
Detailed Explanation:
* nfs-utils provides the NFS server tools.
* /etc/exports defines the exported directory and allowed client network.
* exportfs -rav reloads exports.
* nfs-server must be enabled and started.
* If a firewall is enabled, the NFS service must be allowed.
* RHEL 10 network file services documentation covers NFS server configuration. ( Red Hat
Documentation )

See the solution below in Explanation.
Explanation:
Solution:
Create the Quadlet file:
mkdir -p /etc/containers/systemd
cat > /etc/containers/systemd/sleepy.container < < 'EOF'
[Container]
Image=registry.access.redhat.com/ubi10/ubi
ContainerName=sleepy
Exec=sleep 3600
[Install]
WantedBy=multi-user.target
EOF
Reload and enable:
systemctl daemon-reload
systemctl enable --now sleepy.service
systemctl status sleepy.service
Detailed Explanation:
* Quadlet is the preferred modern way to manage Podman containers with systemd for new configurations.
* The .container file is translated into a systemd-managed service.
* RHEL 10 documentation notes that podman generate systemd still exists, but Quadlets are preferred for new setups. ( Red Hat Documentation )
