Hi Benoit,
Thanks for quick reply.
I have docker with following
[root@8f57181df3a1 vpp_c_api_examples]# rpm -qa | grep vpp
vpp-lib-21.06.0-4~g0d9d3a0.x86_64
vpp-api-lua-21.06.0-4~g0d9d3a0.x86_64
vpp-api-python3-21.06.0-4~g0d9d3a0.x86_64
vpp-debuginfo-21.06.0-4~g0d9d3a0.x86_64
vpp-selinux-policy-21.06.0-4~g0d9d3a0.x86_64
vpp-21.06.0-4~g0d9d3a0.x86_64
vpp-plugins-21.06.0-4~g0d9d3a0.x86_64
vpp-devel-21.06.0-4~g0d9d3a0.x86_64
This will vpp running in it.
