Paigaldamine

Väited

• VPP tarkvara paigaldatakse https://packagecloud.com/ repositooriumist
• 2024 aasta suvel on kõige värskem toetatud Ubuntu operatsioonisüsteemi versioon 22.04
• paigaldusjuhend asub aadressil https://s3-docs.fd.io/vpp/24.06/gettingstarted/installing/ubuntu.html

apt repo seadistuse lisamiseks sobib avada https://packagecloud.io/fdio/release ning pressida nupul 'Debian', tulemusena pakutakse kopeerida selline käsk

# curl -s https://packagecloud.io/install/repositories/fdio/release/script.deb.sh | bash

käsu andmise tulemusena tekitatakse muu hulgas nt selline apt seadistus Ubuntu 22.04 puhul

# ls -ld /etc/apt/sources.list.d/fdio_release.list /etc/apt/keyrings/fdio_release-archive-keyring.gpg
-rw-r--r-- 1 root root 2823 Aug 12 22:26 /etc/apt/keyrings/fdio_release-archive-keyring.gpg
-rw-r--r-- 1 root root  357 Aug 12 22:26 /etc/apt/sources.list.d/fdio_release.list

# cat /etc/apt/sources.list.d/fdio_release.list

vpp tarkvara põhiosa paigaldamiseks sobib öelda

# apt-get install vpp vpp-plugin-core vpp-plugin-dpdk
