Testing with cEOS

Last edited by Malte Bauch

  1. Install containerlab on your machine.

    containerlab and cEOS do not work with cgroupsv2 enabled! This is tracked in this upstream issue. Switch back to cgroupsv1 with the following kernel parameter systemd.unified_cgroup_hierarchy=0.

    Use ceos:4.28.0F if you have cgroupsv2 enabled on your system.

  2. Use the following config to get two cEOS containers running.

name: gosdn-arista-base-topo

mgmt:
  network: gosdn-dev-net

topology:
  kinds:
    ceos:
      image: registry.code.fbi.h-da.de/danet/gosdn/ceos:latest
  nodes:
    ceos0:
      kind: ceos
    ceos1a:
      kind: ceos

  links:
    - endpoints: ["ceos0:eth1", "ceos1a:eth1"]

  1. Run containerlab deploy --topo development.clab.yaml to deploy and containerlab destroy --topo development.clab.yaml to destroy the stack.

  2. You should now start the controller and init the gosdn-cli with ./gosdnc --controller 127.0.0.1:55055 init.

  3. Add a new device with ./gosdnc dev create -a 172.20.20.2:6030 -u admin -p admin --name='test-ceos-1' and remember the UUID of the device.

➜ gosdnc dev list                                                            
INFO[0000] OND 1: name: dev1, uuid: 5fb6e872-220d-492d-bf92-0d63a84d9841
  1. Test if you can get the hostname of the device via gNMI.
➜ gosdnc dev get 5fb6e872-220d-492d-bf92-0d63a84d9841 /system/config/hostname
INFO[0000] timestamp:1643195928009506201 ond:{id:"5fb6e872-220d-492d-bf92-0d63a84d9841" name:"dev1" device:{timestamp:1643195928009490650 update:{path:{element:"system" element:"config" element:"hostname"} val:{string_val:"ceos1a"}}}} <nil>
  1. You can also use gnmic to debug issues with cEOS.
gnmic -a 172.20.20.2:6030 -u admin -p admin --insecure capabilities
