Kevin W Tech Notes
3 min readFeb 20, 2021

1. Download cEOS image from Arista website and import into docker

[root@beta-control-01 Downloads]# docker import cEOS64-lab-4.25.1F.tar.xz  ceos:4.25.1F
sha256:a6e939129819fabf9fe58a92d8bbc95e4c6f169a68d12ad3d2d60a223fc0a49e

2. Create cEOS

[root@beta-control-01 Downloads]# docker create --name=ceos-r1 -p 4000:8080 -p 4001:6030 -p 4002:6061 -p 4003:8081 -p 4423:443 --privileged -e INTFTYPE=eth -e ETBA=4 -e SKIP_ZEROTOUCH_BARRIER_IN_SYSDBINIT=1 -e CEOS=1 -e EOS_PLATFORM=ceoslab -e container=docker -i -t ceos:4.25.1F /sbin/init systemd.setenv=INTFTYPE=eth systemd.setenv=ETBA=4 systemd.setenv=SKIP_ZEROTOUCH_BARRIER_IN_SYSDBINIT=1 systemd.setenv=CEOS=1 systemd.setenv=EOS_PLATFORM=ceoslab systemd.setenv=container=docker systemd.setenv=MAPETH0=1 systemd.setenv=MGMT_INTF=eth0

3. Create network and connet it

[root@beta-control-01 Downloads]# docker network create r1r2-0 
[root@beta-control-01 Downloads]# docker network connect r1r2-0 ceos-r1

4. Connect to ceos

[root@beta-control-01 Downloads]# docker exec -it ceos-r1 Clilocalhost(config)#show ver
 cEOSLab

Or you can use the following docker-compose file to build a 5 nodes leaf-spine topology automatically

[root@beta-control-01 ceos]# cat docker-compose.yml
