In the Kube logs of the pod, i see 'Err:1 http://security.ubuntu.com/ubuntu bionic-security InRelease Temporary failure resolving http://security.ubuntu.com '. My guess is its trying to do a apt update.

As we are on disconnected network, we have a server hosting the repo but on a differennt name.

Hi SubstantialElk6 , which apt-get command are you referring to?

Hey SubstantialElk6 ,
You can see the bash script that installs the container https://github.com/allegroai/clearml-agent/blob/master/clearml_agent/glue/k8s.py#L61 .
You are correct that it does do apt-get update in order to install some stuff.
You can override this entire list of commands by adding another bash script as a string using the container_bash_script argument. Make sure you add it to the example script (should be added to the initialization https://github.com/allegroai/clearml-agent/blob/master/examples/k8s_glue_example.py#L75 ). You should also make sure you have all the other things installed and that clearml_agent is executed in the end of the bash script.
