Set up DPDK on On-Premises Worker Nodes

Install the following dependencies.
Run all commands on the worker node on which you would like to set up DPDK.
For CentOS:

yum groupinstall 'Development Tools' -y
yum install net-tools pciutils -y
yum install git gcc make -y
yum install numactl-devel -y
yum install which -y
yum install -y sudo libhugetlbfs-utils libpcap-devel kernel kernel-devel kernel-headers
yum update -y
yum install epel-release -y
yum install python36 -y

For Ubuntu OS:

sudo apt install build-essential
sudo apt-get install libnuma-dev
After installing the dependencies:
Download the DPDK tar file from https://fast.dpdk.org/rel/. See DPDK documentation for compilation steps.

wget https://fast.dpdk.org/rel/dpdk-19.11.9.tar.xz

Untar the file.

tar -xvf dpdk-19.11.9.tar.xz
cd  dpdk-stable-19.11.9

Compile the file. The compiled file will be in the

x86_64-native-linuxapp-gcc

subfolder

make install T=x86_64-native-linuxapp-gcc
Insert the compiled kernel module statistically or dynamically during runtime (modprobe/insmod). For more information, see kernel module.
cd x86_64-native-linuxapp-gcc/kmod
insmod igb_uio.ko
insmod rte_kni.ko
On Ubuntu, if you see the error—
insmod: ERROR: could not insert module igb_uio.ko
, insert
uio
module first.
modprobe uio
Use distribution specific ways to insert modules during boot. Alternatively, you can create a service that runs the modprobe/insmod commands every time the system boots.
cp <service-file> to /etc/systemd/system
sudo systemctl daemon-reload
Activate and mount 2M hugepages of size 2048K.
You can also activate hugepages using the service script in Step 4.
echo 2048 > /sys/devices/system/node/node0/hugepages/hugepages-2048/nr_hugepages
echo 4292967296 > /sys/fs/cgroup/hugetlb/kubepods.slice/hugetlb.2MB.limit_in_bytes
mkdir /mnt/huge
mount -t hugetlbfs nodev /mnt/huge
Create a snapshot of the VM for future use.
