1. Create docker-setup-renderd128.sh

sudo nano /usr/local/bin/docker-setup-renderd128.sh

#!/bin/bash
read minor major < <(stat -c '%T %t' /dev/dri/renderD128)
if [[ -z $minor || -z $major ]]; then
    echo 'Device not found'
    exit
fi
dminor=$((0x${minor}))
dmajor=$((0x${major}))
CID=`docker ps -a --no-trunc | grep plexinc/pms-docker:latest | head -1 |  awk '{print $1}'`
if [[ -z $CID ]]; then
    echo 'CID not found'
    exit
fi
echo 'Setting permissions'
echo "c $dmajor:$dminor rwm" > /sys/fs/cgroup/devices/docker/$CID/devices.allow


2. Set permissions:

sudo chmod 644 /usr/local/bin/docker-setup-renderd128.sh

3.Create docker-event-listener.sh

sudo nano /usr/local/bin/docker-event-listener.sh

Copy the following content:

#!/bin/bash
docker events --filter 'event=start'| \
while read line; do
    /usr/local/bin/docker-setup-renderd128.sh
done


4.Set permissions:

sudo chmod 644 /usr/local/bin/docker-event-listener.sh

5. Create docker-event-listener.service

sudo nano /etc/systemd/system/docker-event-listener.service

Copy the following content:

[Unit]
Description=Docker Event Listener for renderD128 decoder
After=network.target
StartLimitIntervalSec=0
[Service]
Type=simple
Restart=always
RestartSec=1
User=root
ExecStart=/bin/bash /usr/local/bin/docker-event-listener.sh

[Install]
WantedBy=multi-user.target


6. Set permissions:

sudo chmod 644 /etc/systemd/system/docker-event-listener.service

7. Reload daemon

sudo systemctl daemon-reload

8. Start Docker event listener

sudo systemctl start docker-event-listener.service

9. Status Docker event listener

sudo systemctl status docker-event-listener.service

10. Enable Docker event listener

sudo systemctl enable docker-event-listener.service
