docker - 私有(private) docker 注册表和 python

Question

我没有使用来自 python 的私有(private) docker 注册表。似乎没有读取环境配置。

主要步骤和错误

在 /etc/docker/registries.yaml我将私有(private)注册表定义为

mirrors:
  "192.168.2.62:5055":
    endpoint:
      - "http://192.168.2.62:5055"

但是，当我执行

import docker

client = docker.from_env()
image_tag = "192.168.2.62:5055/dockertest:latest"
for line in client.images.push(repository=image_tag, stream=True, decode=True):
    if 'error' in line and line['error']:
        print(line['error'])

我收到错误消息

Get https://192.168.2.62:5055/v2/: http: server gave HTTP response to HTTPS client

用于复制 这个例子:

(您需要将 IP 编辑为本地机器 IP)

我使用 docker-compose 在 docker 容器中启动了私有(private)注册表

version: '3'
services:
   registry:
     image: registry:2
     ports:
     - 192.168.2.62:5055:5000

接下来我定义了docker文件

%%writefile /tmp/docker_test/Dockerfile

FROM alpine:3.7
CMD ["echo","HELLO WORLD"]

并使用在 python 中构建它

import docker

client = docker.from_env()
image, logs = client.images.build(dockerfile = "Dockerfile",
                               path = "/tmp/docker_test",
                               tag = "192.168.2.62:5055/dockertest")

print(image)
print(logs)
for l in logs:
    print(l)

Answer 1

registries.yaml是来自 Kubernetes 的注册表配置。特别是 k3s .要重新配置本地 docker，需要重新配置 /etc/docker/daemon.json并添加以下行

{ "insecure-registries":["localhost:5055","192.168.2.62:5055"] }
