Virtual-Kubelet CLI

This project provides a library for rapid prototyping of a virtual-kubelet node. It is not intended for production use and may have breaking changes, but takes as much as made sense from the old command line code from github.com/virtual-kubelet/virtual-kubelet.

Usage

package main

import (
    "context"
    "errors"

    "github.com/sirupsen/logrus"
    cli "github.com/virtual-kubelet/node-cli"
    logruscli "github.com/virtual-kubelet/node-cli/logrus"
    "github.com/virtual-kubelet/node-cli/provider"
    "github.com/virtual-kubelet/virtual-kubelet/log"
    logruslogger "github.com/virtual-kubelet/virtual-kubelet/log/logrus"
)

func main() {
    ctx := cli.ContextWithCancelOnSignal(context.Background())
    logger := logrus.StandardLogger()

    log.L = logruslogger.FromLogrus(logrus.NewEntry(logger))
    logConfig := &logruscli.Config{LogLevel: "info"}

    node, err := cli.New(ctx,
        cli.WithProvider("demo", func(cfg provider.InitConfig) (provider.Provider, error) {
            return nil, errors.New("your implementation goes here")
        }),
        // Adds flags and parsing for using logrus as the configured logger
        cli.WithPersistentFlags(logConfig.FlagSet()),
        cli.WithPersistentPreRunCallback(func() error {
            return logruscli.Configure(logConfig, logger)
        }),
    )

    if err != nil {
        panic(err)
    }
    // Args can be specified here, or os.Args[1:] will be used.
    if err := node.Run(ctx); err != nil {
        panic(err)
    }
}
