Requirements
Kubernetes cluster

TestProject Agent => v0.66.4 
Deployment
This YAML snippet spins up 3 deployments:
TestProject Agent
Standalone selenium with pre-installed Chrome
Standalone selenium with pre-installed Firefox
The TestProject Agent will automatically detect the Chrome & Firefox containers.
By setting the TP_API_KEY environment variable we instruct the Agent to automatically register TestProject Agent. The API key can be created in the TestProject Web Application (as described here).
For enhanced security, it's recommended to use Kubernetes secrets for setting the TP_API_KEY.
 Create file '.secret' with TP_API_KEY.
 Then create the testproject-secrets as following:

kubectl create secret generic testproject-secrets --from-literal "TP_API_KEY=$(cat .secret)"
2. Save the code below as k8s-testproject.yaml , then execute that YAML file in your local Kubernetes environment.
kubectl apply -f k8s-testproject.yaml
Content of k8s-testproject.yaml as following:
# To execute this yml file use this command in your local kubernetes environment `kubectl apply -f k8s-testproject.yaml

Running multiple agents
The following will bring up an additional agent named My First k8s Agent-2
cat k8s-testproject.yaml  | sed "s/My First k8s Agent/My First k8s Agent-2/g" | sed "s/testproject-agent/testproject-agent-2/g" | kubectl apply -f - ;
As result, You will have 2 TestProject Agents:

The first one from the firstly run with default parameters bring up the latest Firefox and Chrome
The second brings up an additional agent named  My First k8s Agent-2 that work against the same Firefox and Chrome as My First k8s Agent 
Test different browser versions
The following  will bring up an additional TestProject agent named My First k8s Agent-3
Firefox with version standalone-firefox:86.0
cat k8s-testproject.yaml  | sed "s/My First k8s Agent/My First k8s Agent-3/g" | sed "s/testproject-agent/testproject-agent-3/g" |  sed "s/name: firefox/name: firefox-3/g" | sed "s/selenium\/standalone-firefox/selenium\/standalone-firefox:86.0/g" | kubectl apply -f - ;
As result, you will have 3 TestProject Agents:

the first one My First k8s Agent from the firstly run with default parameters and the latest Firefox and Chrome
the second My First k8s Agent-2 running with default parameters and the latest Firefox and Chrome
the third My First k8s Agent-3 that work against the latest Chrome but Firefox:86.0
