This documentation provides a detailed step-by-step guide for configuring the development environment of controlplaneio-fluxcd/d1-fleet. Refer to the following sections for precise configurations and code examples relevant to expert developers looking to optimize their setup.

Configuration Overview

The configuration of d1-fleet requires several components to be defined. In the development environment, focus on core configuration files that control behavior and features. This includes setting environment variables, modifying configuration files, and utilizing command-line arguments where necessary.

Step 1: Environment Variables

Set essential environment variables that dictate the behavior of the d1-fleet. These variables can be defined in the shell configuration files, such as .bashrc or .zshrc, or exported directly in the terminal before launching the application.

export D1_FLEET_API_ENDPOINT="https://api.dev.yourdomain.com"
export D1_FLEET_LOG_LEVEL="debug"
export D1_FLEET_ENABLE_FEATURE_X=true
  • D1_FLEET_API_ENDPOINT: Specifies the endpoint for the development environment API.
  • D1_FLEET_LOG_LEVEL: Controls the verbosity of logs. Options typically include info, warning, error, or debug.
  • D1_FLEET_ENABLE_FEATURE_X: Toggle specific features for testing.

Step 2: Configuration File

Modify the configuration file, usually found at ./config/d1-fleet.yaml, to adjust default settings.

apiVersion: v1
kind: Config
metadata:
  name: d1-fleet-config
spec:
  fleet:
    deployment:
      replicas: 3
      strategy: RollingUpdate
    features:
      enabled:
        - featureX
    logging:
      level: debug
      output: stdout
  • replicas: Adjusts the number of pod replicas for scaling.
  • strategy: Defines the deployment strategy; rolling updates are generally safer for production environments.
  • enabled features: List features that should be active in the development setup.

Step 3: Command-Line Arguments

When starting d1-fleet, you may specify additional command-line options to override default configurations or environment variables. This is done by appending flags when invoking the application.

./d1-fleet start --config ./config/d1-fleet.yaml --log-level debug --disable-feature-y
  • –config: Points to the YAML configuration file for custom settings.
  • –log-level: Overrides the default log level specified in the configuration file.
  • –disable-feature-y: Disables a specific feature for the runtime.

Step 4: Service Configuration in Kubernetes

When deploying d1-fleet on Kubernetes, ensure to configure the deployment manifests located in the k8s/ directory.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: d1-fleet
spec:
  replicas: 3
  selector:
    matchLabels:
      app: d1-fleet
  template:
    metadata:
      labels:
        app: d1-fleet
    spec:
      containers:
      - name: d1-fleet
        image: your-image-repo/d1-fleet:latest
        env:
        - name: D1_FLEET_API_ENDPOINT
          value: "https://api.dev.yourdomain.com"
        ports:
        - containerPort: 8080
  • containers.env: Set the same environment variables as discussed earlier within the Kubernetes deployment to ensure consistency across the environment.

Conclusion

By configuring environment variables, adjusting the configuration file, utilizing command-line arguments effectively, and ensuring correct Kubernetes settings, one can fully optimize the controlplaneio-fluxcd/d1-fleet for a robust development environment.
