在下文中一共展示了ConfFromBytes函数的3个代码示例,这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞,您的评价将有助于我们的系统推荐出更棒的Golang代码示例。

示例1: Init

func (plugin *kubenetNetworkPlugin) Init(host network.Host, hairpinMode componentconfig.HairpinMode, nonMasqueradeCIDR string) error {
	plugin.host = host
	plugin.hairpinMode = hairpinMode
	plugin.nonMasqueradeCIDR = nonMasqueradeCIDR
	plugin.cniConfig = &libcni.CNIConfig{
		Path: []string{DefaultCNIDir, plugin.vendorDir},
	}

	if link, err := findMinMTU(); err == nil {
		plugin.MTU = link.MTU
		glog.V(5).Infof("Using interface %s MTU %d as bridge MTU", link.Name, link.MTU)
	} else {
		glog.Warningf("Failed to find default bridge MTU: %v", err)
	}

	// Since this plugin uses a Linux bridge, set bridge-nf-call-iptables=1
	// is necessary to ensure kube-proxy functions correctly.
	//
	// This will return an error on older kernel version (< 3.18) as the module
	// was built-in, we simply ignore the error here. A better thing to do is
	// to check the kernel version in the future.
	plugin.execer.Command("modprobe", "br-netfilter").CombinedOutput()
	err := utilsysctl.SetSysctl(sysctlBridgeCallIptables, 1)
	if err != nil {
		glog.Warningf("can't set sysctl %s: %v", sysctlBridgeCallIptables, err)
	}

	plugin.loConfig, err = libcni.ConfFromBytes([]byte(`{
  "cniVersion": "0.1.0",
  "name": "kubenet-loopback",
  "type": "loopback"
}`))
	if err != nil {
		return fmt.Errorf("Failed to generate loopback config: %v", err)
	}

	plugin.nsenterPath, err = plugin.execer.LookPath("nsenter")
	if err != nil {
		return fmt.Errorf("Failed to find nsenter binary: %v", err)
	}

	// Need to SNAT outbound traffic from cluster
	if err = plugin.ensureMasqRule(); err != nil {
		return err
	}
	return nil
}

示例2: Event

	if name != network.NET_PLUGIN_EVENT_POD_CIDR_CHANGE {
		return
	}

	plugin.mu.Lock()
	defer plugin.mu.Unlock()

	podCIDR, ok := details[network.NET_PLUGIN_EVENT_POD_CIDR_CHANGE_DETAIL_CIDR].(string)
	if !ok {
		glog.Warningf("%s event didn't contain pod CIDR", network.NET_PLUGIN_EVENT_POD_CIDR_CHANGE)

	}

	if plugin.netConfig != nil {

		return
	}

	glog.V(5).Infof("PodCIDR is set to %q", podCIDR)
	_, cidr, err := net.ParseCIDR(podCIDR)
	if err == nil {
		setHairpin := plugin.hairpinMode == componentconfig.HairpinVeth
		// Set bridge address to first address in IPNet
		cidr.IP.To4()[3] += 1

		json := fmt.Sprintf(NET_CONFIG_TEMPLATE, BridgeName, plugin.MTU, network.DefaultInterfaceName, setHairpin, podCIDR, cidr.IP.String())
		glog.V(2).Infof("CNI network config set to %v", json)
		plugin.netConfig, err = libcni.ConfFromBytes([]byte(json))

			glog.V(5).Infof("CNI network config:\n%s", json)

			// Ensure cbr0 has no conflicting addresses; CNI's 'bridge'
			// plugin will bail out if the bridge has an unexpected one
			plugin.clearBridgeAddressesExcept(cidr)
		}
	}

	if err != nil {
		glog.Warningf("Failed to generate CNI network config: %v", err)
	}

示例3: getLoNetwork

func getLoNetwork(vendorDirPrefix string) *cniNetwork {
	loConfig, err := libcni.ConfFromBytes([]byte(`{
  "cniVersion": "0.1.0",
  "name": "cni-loopback",
  "type": "loopback"
}`))
	if err != nil {
		// The hardcoded config above should always be valid and unit tests will
		// catch this
		panic(err)
	}
	cninet := &libcni.CNIConfig{
		Path: []string{vendorCNIDir(vendorDirPrefix, loConfig.Network.Type), DefaultCNIDir},
