go mod download 不会下载单个库；如何在不操作整个 vendor 缓存的情况下修改导入单个库

标签 go go-modules prometheus-operator

(免责声明:对本描述中使用的错误词语表示歉意。我仍在熟悉 go)

我的理解是，go 模块非常挑剔，因此这个问题涵盖了与 go 模块和 prometheus 运算符相关的几个主题我正在尝试下载并导入库。

一个巨大的要求:我无法进行大规模go mod下载/升级，因为下游deps在我的 vendor 目录中升级，并且我们的代码中发生了各种破坏。我正在努力避免这种情况。我只想“安装”这个库(以及任何必要的辅助工具)并完成它。

综上所述，使用 go mod (或其他合适的工具)获取 "github.com/coreos/prometheus-operator/pkg/apis/的正确方法是什么？ Monitoring/v1" 这不会更新我的所有 vendor 库？我只需要导入 v1 api 即可以编程方式设置和读取集群中的 servicemonitor。

$ go mod download -x github.com/coreos/prometheus-operator/pkg/apis/monitoring/v1
module github.com/coreos/prometheus-operator/pkg/apis/monitoring/v1: not a known dependency

或

$ go get github.com/coreos/prometheus-operator/pkg/apis/monitoring/v1
go: found github.com/coreos/prometheus-operator/pkg/apis/monitoring/v1 in github.com/coreos/prometheus-operator v0.41.1

我的导入

import (
    "context"
    "encoding/base64"
    "fmt"
    v1 "k8s.io/api/core/v1"
    "k8s.io/apimachinery/pkg/util/intstr"
    "strings"
    "text/template"
    "time"

    "github.com/google/uuid"

    coreosv1 "github.com/coreos/prometheus-operator/pkg/apis/monitoring/v1"
    "github.com/go-kit/kit/log"

    metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"
    "k8s.io/client-go/kubernetes"
    "k8s.io/client-go/tools/clientcmd"
)

我使用这个库的实际代码如下所示:

    // define service monitor object
    serviceMonitorObject := &coreosv1.ServiceMonitor{
        ObjectMeta: metav1.ObjectMeta{
            Name:      objectMetaDataName,
            // TODO: fix namespace
            Namespace: "monitoring",
            Labels:    labels,
        },
        Spec: coreosv1.ServiceMonitorSpec{
            Selector: metav1.LabelSelector{
                MatchLabels: labels,
            },
            NamespaceSelector: coreosv1.NamespaceSelector{
                MatchNames: []string{
                    "monitoring",
                },
            },
            Endpoints: []coreosv1.Endpoint{
                {
                    Port: "metrics",
                    Interval: "10s",
                    HonorLabels: true,
                },
            },
        },
    }

但是，我似乎不能只导入一个库。任何建议或帮助将不胜感激。

github.com/coreos/prometheus-operator v0.41.1 中的错误 github.com/coreos/prometheus-operator/pkg/apis/monitoring/v1 表明也许我只是导入 github.com/coreos/prometheus-operator 但是当我这样做时，我的 servicemonitor 定义失败。

编辑

我rm编辑了我的go.{mod,sum}和vendor目录以及git reset --hard 我的环境，将 vendor 状态恢复到我工作之前的状态。我运行了以下命令，但如您所见，get 似乎可以工作，但 /project/vendor/*/下不存在 coreos 目录.

$ go get -x github.com/coreos/prometheus-operator/
# get https://proxy.golang.org/github.com/coreos/@v/list
# get https://proxy.golang.org/github.com/@v/list
# get https://proxy.golang.org/github.com/coreos/prometheus-operator/@v/list
# get https://proxy.golang.org/github.com/@v/list: 410 Gone (0.794s)
# get https://proxy.golang.org/github.com/coreos/@v/list: 410 Gone (0.886s)
# get https://proxy.golang.org/github.com/coreos/prometheus-operator/@v/list: 200 OK (0.897s)
go: github.com/coreos/prometheus-operator upgrade => v0.41.1
$ find vendor -name '*prometheus*'
vendor/github.com/go-kit/kit/metrics/prometheus
vendor/github.com/go-kit/kit/metrics/prometheus/prometheus.go
vendor/github.com/prometheus
vendor/github.com/prometheus/client_golang/prometheus

再次重置我的环境。执行了以下操作:

$ go mod download -x github.com/coreos/prometheus-operator/...
warning: pattern "github.com/coreos/prometheus-operator/..." matched no module dependencies
$ go mod download -x github.com/coreos/prometheus-operator/
module github.com/coreos/prometheus-operator/: not a known dependency

根据文档，以下内容应显示使用的所有 mod(添加 grep core 以获得更简短的输出):

$ go list -m all | grep core
github.com/coreos/bbolt v1.3.2
github.com/coreos/etcd v3.3.10+incompatible
github.com/coreos/go-etcd v2.0.0+incompatible
github.com/coreos/go-oidc v2.2.1+incompatible
github.com/coreos/go-semver v0.3.0
github.com/coreos/go-systemd v0.0.0-20190321100706-95778dfbb74e
github.com/coreos/pkg v0.0.0-20180928190104-399ea9e2e55f
github.com/coreos/prometheus-operator v0.41.1

但是，我仍然无法编译:

我运行了go modvendor，我又回到了整个 vendor 树都被更改的情况:

$ g st | grep -c vendor

这只是世界的现状吗？我是否无法在不对整个 vendor 树进行大量更改的情况下导入此库，这完全破坏了我的代码!这太荒谬了!

最佳答案

go get -d github.com/coreos/prometheus-operator/pkg/apis/monitoring/v1 是添加对提供该包的模块的最新版本的依赖项的正确方法.

当go get添加模块依赖项时，它会根据需要升级其他依赖项，以满足新模块的要求。这可能就是为什么您在运行 go modvendor 时看到很多变化的原因。

如果您想最小化这些更改，您可能需要显式选择旧版本(以便它具有旧版本的要求):

go get -d github.com/coreos/prometheus-operator/pkg/apis/monitoring/v1@$OLD_VERSION
