(Docker SDK)上传镜像到私有仓库(ssl、身份认证)

API：https://docker-py.readthedocs.io/en/stable/

环境：python：3.7.3

配置参数：

cert = os.path.join(BASE_DIR, "utils/cert.pem")
key = os.path.join(BASE_DIR, "utils/key.pem")

docker_server = "xx.xx.xx.xx:5555"
registry_server = "xx.xx.xx:5000"

# tls配置
tls_config = docker.tls.TLSConfig(
    client_cert=(cert, key),
    ssl_version=ssl.PROTOCOL_TLSv1_2,
)

• 连接docker客户端

client = docker.DockerClient(base_url=docker_server, tls=tls_config)

• 导入镜像

# 　打开文件，获取二进制数据
with open(images, ‘rb‘) as f:
    content = f.read()

# 导入镜像
images = client.images.load(content)

• 查看镜像是否正常

# 运行容器  detach=True：返回一个Container对象
try:
    container = client.containers.run(images[0], detach=True)
except docker.errors.ImageNotFound as e:
    print("指定的图像不存在！")
except docker.errors.APIError as e:
    print("服务器返回错误！")
# 停止运行的容器
container.stop()
# 删除容器
container.remove()

• 给镜像打标签

tags = images[0].tags[0].split(‘:‘)
# tags: ex. hello-world:latest
rest = images[0].tag(registry_server + "/" + tags[0].split(‘/‘)[-1], tags[1])
# rest: True

• 登陆私有仓库

rest = client.login(username=‘admin‘, password=‘admin‘, registry=registry_server)
# rest：‘IdentityToken‘: ‘‘, ‘Status‘: ‘Login Succeeded‘

• 上传镜像到私有仓库

# 上传镜像到私有仓库
for line in client.images.push(registry_server + "/" + images[0].tags[0], stream=True, decode=True):
    print(line)
# rest: ‘status‘: ‘The push refers to a repository [xx.xx.xx:5000/hello-world]‘
#        ‘status‘: ‘Preparing‘, ‘progressDetail‘: , ‘id‘: ‘af0b15c8625b‘
#        ‘status‘: ‘Layer already exists‘, ‘progressDetail‘: , ‘id‘: ‘af0b15c8625b‘
#        ‘status‘: ‘latest: digest: sha256:92c7f9c92844bbbb5d0a101b22f7c2a7949e40f8ea90c8b3bc396879d95e899a size: 524‘
#        ‘progressDetail‘: , ‘aux‘: ‘Tag‘: ‘latest‘, ‘Digest‘: ‘sha256:92c7f9c92844bbbb5d0a101b22f7c2a7949e40f8ea90c8b3bc396879d95e899a‘, ‘Size‘: 524

• 删除打标签镜像

client.images.remove(registry_server + "/" + images[0].tags[0])
