Hi
did you try master or dev branch?

from sfc-controller.

Jingzhao123 commented on July 26, 2024

On master branch

from sfc-controller.

stanislav-chlebec commented on July 26, 2024

Please try to combine contiv/vpp master branch and ligato/sfc-controller dev branch.

from sfc-controller.

stanislav-chlebec commented on July 26, 2024

IBut please wait for PR #31
to be merged

from sfc-controller.

stanislav-chlebec commented on July 26, 2024

Or change the Dockerfiles as you did before for alpine versions....

from sfc-controller.

Hi
I am trying to examine the situation.
I found out that you need compatible version of sfc-controller and vpp-agent.
I am going to try these:
https://cloud.docker.com/u/ligato/repository/docker/ligato/vpp-agent-arm64
I will take the docker image v2.0.0-beta-190-g19f3215d
https://cloud.docker.com/u/ligato/repository/docker/ligato/sfc-controller-arm64
I will take the docker image built on dev branch
docker pull ligato/sfc-controller-arm64:dev

About these two I now that they work together:
http://147.75.83.101:8080/view/05SFC/job/05SFCIPV6_____vswitch_1x_vpp_1x_novppIPv6_job/22/
http://147.75.83.101:8080/view/05SFC/job/05SFCIPV6_____vswitch_1x_vpp_1x_novppIPv6_job/22/parameters/
http://147.75.83.101:8080/view/05SFC/job/05SFCIPV6_____vswitch_1x_vpp_1x_novppIPv6_job/22/console

Actually it is only prerequisite to our aim to make work that contiv k8s sfc example
It can be found other problems

from sfc-controller.

Hi
Is it OK on dev version? Actually, i still do not verify it on dev version. When i using the latest version, i found that the vnf pod can not create memif interface. Is the issue same with yours?
Thanks.

Corrected errors
1.
Long names of vxlan such as IF_VXLAN_L2PP_NET_SRVC_l2pp_service_chain2_CONN_1_FROM_vppagent_vnf3_port1_TO_contivvpp_vnf4_port1_VNI_5003 were replaced by C1FM31TO41_5003 (where FM=master, FW=worker, 31=vnf3_port1 etc...)
2.
Prefixes were omited in definitions - see keys:

I have the same problem as @Jingzhao123. Have you please any suggestions because i have changed the sfc-controller.yaml as indicated in #33 but no good result

AdelBouridah commented on July 26, 2024

Is there any solution to fix the problem in the SFC controller source. I have done the manual solution of @stanislav-chlebec but i have always long vxlan names and the VNFs crash (CrashLoopBackOff). Which file from the SFC source code is about the generated VXlan names please?

Hi,
we are slowly moving towards implementing service chaining for CNFs in Contiv-VPP directly, which means that an external SFC Controller will not be needed anymore. If you wanted to contribute, feel free to join Contiv slack channel and ping me there:

SFC controller demo is now superseded by SFC functionality built into Contiv-VPP CNI itself. Still work in progress, but already does something. Take a look at https://github.com/contiv/vpp/tree/master/k8s/examples/sfc

from sfc-controller.

The sfc-controller example in Contiv-vpp project can not work as description about sfc-controller HOT 15 OPEN
