Prometheus源码学习(4) 通过2.24对实例化Discoverer代码的改进学习依赖倒置
2024-06-30 05:04:08
前面读的是 2.19.2 版本的代码，最新更新了 2.24.1，发现在实例化 Discoverer 时改进了设计。这个改变是在 2.21 做出的。
2.19.2 中的实现方式
- 在 discovery.Manager 结构体中包含了一个 *provider 的 slice
type Manager struct {...// providers keeps track of SD providers.providers []*provider...
}
- provider 接口提包含了一个 Discoverer 接口类型的字段
// provider holds a Discoverer instance, its configuration and its subscribers.
type provider struct {name stringd Discoverersubs []stringconfig interface{}
}
- 实例化 Discoverer 是在 *Manager 的 registerProviders() 方法中实现的，每个 job 有一套 Provider
方法签名为
func (m *Manager) registerProviders(cfg sd_config.ServiceDiscoveryConfig, setName string) int
参数 cfg 是解析配置文件参数得到的各种 SD 类型
// ServiceDiscoveryConfig configures lists of different service discovery mechanisms.
type ServiceDiscoveryConfig struct {// List of labeled target groups for this job.StaticConfigs []*targetgroup.Group `yaml:"static_configs,omitempty"`// List of DNS service discovery configurations.DNSSDConfigs []*dns.SDConfig `yaml:"dns_sd_configs,omitempty"`// List of file service discovery configurations.FileSDConfigs []*file.SDConfig `yaml:"file_sd_configs,omitempty"`// List of Consul service discovery configurations.ConsulSDConfigs []*consul.SDConfig `yaml:"consul_sd_configs,omitempty"`// List of DigitalOcean service discovery configurations.DigitalOceanSDConfigs []*digitalocean.SDConfig `yaml:"digitalocean_sd_configs,omitempty"`// List of Docker Swarm service discovery configurations.DockerSwarmSDConfigs []*dockerswarm.SDConfig `yaml:"dockerswarm_sd_configs,omitempty"`// List of Serverset service discovery configurations.ServersetSDConfigs []*zookeeper.ServersetSDConfig `yaml:"serverset_sd_configs,omitempty"`// NerveSDConfigs is a list of Nerve service discovery configurations.NerveSDConfigs []*zookeeper.NerveSDConfig `yaml:"nerve_sd_configs,omitempty"`// MarathonSDConfigs is a list of Marathon service discovery configurations.MarathonSDConfigs []*marathon.SDConfig `yaml:"marathon_sd_configs,omitempty"`// List of Kubernetes service discovery configurations.KubernetesSDConfigs []*kubernetes.SDConfig `yaml:"kubernetes_sd_configs,omitempty"`// List of GCE service discovery configurations.GCESDConfigs []*gce.SDConfig `yaml:"gce_sd_configs,omitempty"`// List of EC2 service discovery configurations.EC2SDConfigs []*ec2.SDConfig `yaml:"ec2_sd_configs,omitempty"`// List of OpenStack service discovery configurations.OpenstackSDConfigs []*openstack.SDConfig `yaml:"openstack_sd_configs,omitempty"`// List of Azure service discovery configurations.AzureSDConfigs []*azure.SDConfig `yaml:"azure_sd_configs,omitempty"`// List of Triton service discovery configurations.TritonSDConfigs []*triton.SDConfig `yaml:"triton_sd_configs,omitempty"`
}
方法内部首先声名一个添加 Discoverer 的闭包函数 add()，闭包函数的参数有一个实例化 Discoverer 的方法
add := func(cfg interface{}, newDiscoverer func() (Discoverer, error)) {t := reflect.TypeOf(cfg).String()// 已有的 provider 如果有多个 job 配置了它就把 job_name 追加到 这个provider 的 subs 中。// 否则就新建 providerfor _, p := range m.providers {if reflect.DeepEqual(cfg, p.config) {p.subs = append(p.subs, setName)level.Info(m.logger).Log("msg", "append subscribers", "sub", p.subs)added = truereturn}}d, err := newDiscoverer()if err != nil {level.Error(m.logger).Log("msg", "Cannot create service discovery", "err", err, "type", t)failedCount++return}provider := provider{name: fmt.Sprintf("%s/%d", t, len(m.providers)),d: d,config: cfg,subs: []string{setName},}m.providers = append(m.providers, &provider)added = true}
- 遍历配置文件配置的每种服务发现的类型，调用这种类型的实例化方法（如 dns.NewDiscovery()）来初始化这种SD。
for _, c := range cfg.DNSSDConfigs {add(c, func() (Discoverer, error) {return dns.NewDiscovery(*c, log.With(m.logger, "discovery", "dns")), nil})}for _, c := range cfg.FileSDConfigs {add(c, func() (Discoverer, error) {return file.NewDiscovery(c, log.With(m.logger, "discovery", "file")), nil})}for _, c := range cfg.ConsulSDConfigs {add(c, func() (Discoverer, error) {return consul.NewDiscovery(c, log.With(m.logger, "discovery", "consul"))})}...
这种模式要在 manager.go 文件中导入每一种具体的服务发现器，也就是要在抽象层依赖各个实现。
2.24.1 中的实现方式
- Manager 包装 provider 包装 Discoverer 没有变化
- *Manager.registerProviders() 方法的参数变为了 Config 切片，Config 是接口类型，其中要求实现类要有 NewDiscoverer(DiscovererOptions) (Discoverer, error) 方法。
// Configs is a slice of Config values that uses custom YAML marshaling and unmarshaling
// to represent itself as a mapping of the Config values grouped by their types.
type Configs []Config// A Config provides the configuration and constructor for a Discoverer.
type Config interface {// Name returns the name of the discovery mechanism.Name() string// NewDiscoverer returns a Discoverer for the Config// with the given DiscovererOptions.NewDiscoverer(DiscovererOptions) (Discoverer, error)
}
*Manager.registerProviders() 里面的 add 闭包函数的初始化 Discoverer 方法是调用接口要求的 NewDiscoverer() 方法
d, err := cfg.NewDiscoverer(DiscovererOptions{Logger: log.With(m.logger, "discovery", typ),})
遍历也简化了
for _, cfg := range cfgs {add(cfg)}
- 在 main() 里依赖了 /discovery/install，这个新增的 install 包中导入具体的 SD 作为依赖
package installimport (_ "github.com/prometheus/prometheus/discovery/azure" // register azure_ "github.com/prometheus/prometheus/discovery/consul" // register consul_ "github.com/prometheus/prometheus/discovery/digitalocean" // register digitalocean_ "github.com/prometheus/prometheus/discovery/dns" // register dns_ "github.com/prometheus/prometheus/discovery/dockerswarm" // register dockerswarm_ "github.com/prometheus/prometheus/discovery/ec2" // register ec2_ "github.com/prometheus/prometheus/discovery/eureka" // register eureka_ "github.com/prometheus/prometheus/discovery/file" // register file_ "github.com/prometheus/prometheus/discovery/gce" // register gce_ "github.com/prometheus/prometheus/discovery/hetzner" // register hetzner_ "github.com/prometheus/prometheus/discovery/kubernetes" // register kubernetes_ "github.com/prometheus/prometheus/discovery/marathon" // register marathon_ "github.com/prometheus/prometheus/discovery/openstack" // register openstack_ "github.com/prometheus/prometheus/discovery/triton" // register triton_ "github.com/prometheus/prometheus/discovery/zookeeper" // register zookeeper
)
- 每一个具体的 SD 依赖 /discovery/dicovery，实现接口的 NewDiscoverer(opts discovery.DiscovererOptions) (discovery.Discoverer, error) 方法
// NewDiscoverer returns a Discoverer for the Config.
func (c *SDConfig) NewDiscoverer(opts discovery.DiscovererOptions) (discovery.Discoverer, error) {return NewDiscovery(c, opts.Logger), nil
}
返回的是调用本 SD 自己的 NewDiscovery() 函数得到的具体的SD实例
// NewDiscovery returns a new file discovery for the given paths.
func NewDiscovery(conf *SDConfig, logger log.Logger) *Discovery {if logger == nil {logger = log.NewNopLogger()}disc := &Discovery{paths: conf.Files,interval: time.Duration(conf.RefreshInterval),timestamps: make(map[string]float64),logger: logger,}fileSDTimeStamp.addDiscoverer(disc)return disc
}
模式学习
这样就实现了由抽象依赖实现翻转为实现依赖抽象。
install 是一个中介包，main 依赖它，它的内部导入各个具体的 SD 实现包，这样集中了多个具体实现的导入位置便于修改，也使 main 的导入部分变得简洁。
