在容器中添加不安全的注册表 [英] Adding insecure registry in containerd

问题描述

尝试将不安全的注册表添加到容器配置中，如下所示:

Trying to add insecure registry to containerd config as below:

[plugins."io.containerd.grpc.v1.cri".cni]
      bin_dir = "/opt/cni/bin"
      conf_dir = "/etc/cni/net.d"
      max_conf_num = 1
      conf_template = ""
    [plugins."io.containerd.grpc.v1.cri".registry]
      [plugins."io.containerd.grpc.v1.cri".registry.mirrors]
        [plugins."io.containerd.grpc.v1.cri".registry.mirrors."docker.io"]
          endpoint = ["https://registry-1.docker.io"]
        [plugin."io.containerd.grpc.v1.cri".registry.mirrors."test.http-registry.io"]
          endpoint = ["http://v048011.dom600.lab:5000"]

即使将其添加到 config.toml 中之后，当从不安全的注册表中提取图像时，它也会失败:

Even after adding it to config.toml, when pulling image from the insecure registry, it fails:

sudo ctr image pull v048011.dom600.lab:5000:5000/myjenkins:latest

ctr: failed to resolve reference "v048011.dom600.lab:5000/myjenkins:latest": failed to do request: Head https://v048011.dom600.lab:5000:5000/v2/myjenkins/manifests/latest: http: server gave HTTP response to HTTPS client

在 docker 中，我们可以将 insecure注册表添加到 daemon.json 文件中，而docker会从中提取图像，我该如何实现在 containerd 中也一样吗?在k8s集群中将docker替换为运行时.

In docker we could just add the insecure registry to daemon.json file and docker would pull images from it, how can i achieve the same in containerd ? Replacing docker as runtime in k8s cluster.

推荐答案

添加以下配置:

[plugins."io.containerd.grpc.v1.cri".cni]
      bin_dir = "/opt/cni/bin"
      conf_dir = "/etc/cni/net.d"
      max_conf_num = 1
      conf_template = ""
    [plugins."io.containerd.grpc.v1.cri".registry]
      [plugins."io.containerd.grpc.v1.cri".registry.mirrors]
        [plugins."io.containerd.grpc.v1.cri".registry.mirrors."docker.io"]
          endpoint = ["https://registry-1.docker.io"]
        [plugin."io.containerd.grpc.v1.cri".registry.mirrors."test.http-registry.io"]
          endpoint = ["http://v048011.dom600.lab:5000"]
        [plugins."io.containerd.grpc.v1.cri".registry.configs]
          [plugins."io.containerd.grpc.v1.cri".registry.configs."test.http-registry.io".tls]
            insecure_skip_verify = true

应跳过测试注册表的TLS验证.另请参见注册表TLS通信中的文档配置.

should skip TLS verification for the test registry. See also the documentation on registry TLS communication configuration.
