This adds a new executor type that allows tasks to run on Kubernetes pods,
complementing the existing 'local' and 'container' (docker-compose) executors.
Features:
- New --executor kubernetes flag for `emb tasks run`
- Automatic pod and container discovery based on component configuration
- Configurable label selector via component kubernetes.selector
- Configurable default label via defaults.kubernetes.selectorLabel
- Namespace resolution: CLI flag > K8S_NAMESPACE env > config > 'default'
- Interactive task support with proper TTY handling
- SIGINT handling for graceful termination
New operations:
- GetComponentPodOperation: Resolves component to ready pod and container
- PodExecOperation: Executes commands in pods via WebSocket
Configuration (in .emb.yml):
defaults:
kubernetes:
namespace: production
selectorLabel: app.kubernetes.io/component # default
components:
api:
kubernetes:
selector: app=custom-api # override default selector
container: main # for multi-container pods
