In the minikube hyper-v machine I did deployment of sawtooth-0, using sawtooth config file.
Now when I am checking running pods it seems to have some default ones but while trying to connect with the kubernetes shell container.
C:\Users\Debo>kubectl get --all-namespaces
You must specify the type of resource to get. Use "kubectl api-resources" for a complete list of supported resources.
error: Required resource not specified.
Use "kubectl explain <resource>" for a detailed description of that resource (e.g. kubectl explain pods).
See 'kubectl get -h' for help and examples

If i understand your use case you are trying to filter the sawtooth-0 pod from list of give pods in a namespace and then open a interactive session toward container running inside it where you know the container name.
So to solve above i took the sawtooth config file attached in question and started two instance of it sawtooth-0 and sawtooth-1 alongside few of dummy pods then i use this command on windows power shell to filter and connect to container on sawtooth-0 pod.
All below was done assuming you need kubectl running on windows powershell
PS C:\Users\winuser> kubectl get pods
