You can find the instance's public IP address in the list of your instances.
Oracle Linux's default user is
opc, use the following command to ssh to your instance (to the host OS). On Linux and macOS, you'll first need to limit the key file permissions using the
chmod 400 path/to/your-private-key.pem
ssh -i path/to/your-private-key.pem opc@INSTANCE_IP
Oracle cloud instances are protected by the Network Security Groups (the cloud firewall feature), so you can stop and disable the in-OS firewall.
sudo systemctl disable firewalld --now
This takes several minutes.
sudo dnf update -y
nouveau, the open-source driver for Nvidia GPUs is usually pre-loaded. It must be disabled to install Nvidia's own driver.
sudo modprobe -r nouveau
Prevent loading of the
nouveau kernel module at boot.
echo "blacklist nouveau" | sudo tee /etc/modprobe.d/blacklist.conf
sudo dnf --enablerepo=ol8_developer_EPEL -y install dkms sudo dnf -y config-manager --add-repo http://developer.download.nvidia.com/compute/cuda/repos/rhel8/x86_64/cuda-rhel8.repo
sudo dnf module -y install nvidia-driver:515-dkms sudo modprobe nvidia
The following command should print a meaningful output.
Follow the Setting up Docker on CentOS 7/8 chapter from the official Nvidia docs (Centos 8 variant)
This allows running the docker command as a non-root user.
sudo groupadd docker sudo usermod -aG docker $USER newgrp docker
Follow the Setting up NVIDIA Container Toolkit chapter from the official Nvidia docs (Centos 8 variant). You need to use the following command for setting up the Nvidia Container toolkit repository instead of the official one (Oracle Linux 8 isn't supported by their command).
curl -s -L https://nvidia.github.io/libnvidia-container/centos8/libnvidia-container.repo | sudo tee /etc/yum.repos.d/nvidia-container-toolkit.repo
We use the
docker-compoe tool for making it easier to launch our Docker container. Use the following command to install the
sudo curl -L https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose sudo chmod +x /usr/local/bin/docker-compose
Next, check that the
docker-compose tool is successfully installed. The following command should return meaningful output.
The mDNS service mustn't be active in the host OS for NDI discovery to work. If present, this command removes it from the host OS:
sudo yum list installed avahi sudo yum remove avahi
To receive and send streams with high-bitrate codecs (e.g., JPEG2000 or JPEG-XS), Live Transcoder needs to increase the UDP kernel buffer size. However, the default maximum size is too low so it needs to be increased.
SYSCTL_CONF="/etc/sysctl.d/10-udp-buffer-size.conf" sudo sh -c "echo '#kernel send a receive windows buffer sizes' > $SYSCTL_CONF" sudo sh -c "echo 'net.core.rmem_max=262144000' >> $SYSCTL_CONF" sudo sh -c "echo 'net.core.wmem_max=262144000' >> $SYSCTL_CONF" sudo sh -c "echo 'net.core.rmem_default=262144000' >> $SYSCTL_CONF" sudo sh -c "echo 'net.core.wmem_default=262144000' >> $SYSCTL_CONF"
Now load the updated config file.
sudo sysctl -p $SYSCTL_CONF
