Hi all,

I was wondering if there was the possibility to test Prometheus-based streaming telemetry in a lab provided by cEOS docker container.

Is there a change to configure and install TerminAttr and ocprometheus on the cEOS image or it is simply impossible? Anyone that have had success?

You can test ocprometheus on any EOS flavor, be it vEOS-lab/cloudEOS/cEOS/cEOS-lab/EOS/CVX

There's nothing different in the way you'll have to install and use it, you might find these resources useful:

I've used it many times in my lab, a very simple example:

Import the image in docker:

~/images # tamas@tamas # docker import cEOS64-lab-4.23.3.tar.xz ceosimage:c4233M

Create docker network if it’s not already created:

~/images # tamas@tamas # docker network create net1337


Create docker container:

~/images # tamas@tamas # docker create --name=ceos1337 -p 2222:22 -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 ceosimage:c4233M /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


Connect the container to the network

~/images # tamas@tamas # docker network connect net1337 ceos1337

Start container


~/images # tamas@tamas # docker start ceos1337


 Exec into the container (console)


~/images # tamas@tamas # docker exec -it ceos1337 Cli

How to copy the ocprometheus binary if you forgot to expose SSH?


docker cp ocprometheus ceos1337:/mnt/flash/
