Missing Docker Container on lab Model Driven Telemetry

FulvioAllegretti36199 — Thu, 25 Feb 2021 16:10:57 GMT

Hi, was trying to go through the MDT lab and when I logged on the DEV box in theory the relative docker should be installed but it isn't:

(py3venv) [developer@devbox ~]$ docker ps
CONTAINER ID IMAGE COMMAND CREATED

STATUS PORTS NAMES
(py3venv) [developer@devbox ~]$

Am I doing something wrong?

@FulvioAllegretti36199 thanks for reporting this, working with our team to fix this up.

(py3venv) [developer@devbox ~]$ docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

(py3venv) [developer@devbox ~]$ docker info | grep Contain
 Containers: 0

At todays date the issues is still not fixed.

I found a workaround by starting the containers when logged in to the devbox with the following commands:

to start the tig_mdt container in detached mode

docker run -d -p 3000:3000 -p 57500:57500 --name tig_mdt jeremycohoe/tig_mdt

and the yang-explorer in detached mode as well

docker run -d -p 8088:8088 --name yangexplorer hellt/yangexplorer-docker

it should look like in the screenshot

after the two commands are completed continue with the learning lab.

EDIT: the yang explorer don't work after adobe flash isn't supported in todays browsers

If you still want to play with telemetry and yang look at Yang Suite, it can do both.

start with this learning lab.

you also want to add * instead of localhost in the docker-compose.yml before running the docker-compose command, to be able to view the webpage in your browser.

if you still want to have access to the devbox cli while the containers are running use this command instead of the command used in the learning lab.

docker-compose up -d --build

and change the port used by the devices to the port specified in yang suite gRPC telemetry under protocols

Thanks for your details and workaround! I have asked ENG to look at this, as it was resolved and fixed.

Thanks again!
