Debugging a rails application in Minikube
You are trying to get interactive access to your application.
Your problem is caused by the fact that the k8s does not allocate a TTYand stdin buffer for the container by default.
I have replicated your issue and found a solution.
To get an interactive breakpoint you have to add 2 flags to your Deployment yaml to indicate that you need interactive session:
stdin: true tty: trueHere is an example of a deployment:
apiVersion: apps/v1 kind: Deployment metadata: labels: run: test name: test spec: selector: matchLabels: run: test template: metadata: labels: run: test spec: containers: - image: test name: test stdin: true tty: trueYou can find more info about it here.
Remember to use -it option when attaching to pod, like shown below:
kubectl attach -it <pod_name>Let me know if that helped.
