如何通过 nginx ssl 身份验证连接 mlflow 服务器？

Question

系统信息 OS 平台和分布：Windows 10 安装 MLflow：使用 pip MLflow版本：1.24.0版 **Python 版本：Python 3.9.7 **

描述问题我创建了一个 docker-compose 系统，带有 backend/artifact 存储、mlflow 服务器和 nginx 以添加身份验证层。

...
mlflow:
        restart: always
        build: .
        environment:
            - AWS_ACCESS_KEY_ID=${MINIO_USR}
            - AWS_SECRET_ACCESS_KEY=${MINIO_PASS}       
        expose:
            - '5000'
        networks:
            - frontend
            - backend
        depends_on:
            - storage                       
        image: 'mlflow:Dockerfile'
        container_name: mlflow_server_nginx

    nginx:
        restart: always
        build: ./nginx
        container_name: mlflow_nginx
        ports:
            - 5043:443
        links:
            - mlflow:mlflow
        volumes:
            - 'path/to/nginx/auth:/etc/nginx/conf.d'
            - 'path/to/nginx/nginx.conf:/etc/nginx/nginx.conf:ro'
        networks:
            - frontend
        depends_on:
            - mlflow

我已经通过 htpasswd 创建了一个 user/password，并使用 openssl 和我的-mlflow.com 服务器名称创建了一个自定义 SSL CA (.pem/.key)。

构建 docker-compose 系统后，我可以通过浏览器访问 mlflow UI。但是当我尝试使用 python 尝试不同的方法来创建一个新实验时，我得到了下一个错误：执行代码 1:

# Setting the requried environment variables
os.environ['MLFLOW_S3_ENDPOINT_URL'] = 'https://localhost:9000'
os.environ['AWS_ACCESS_KEY_ID'] = 'user'
os.environ['AWS_SECRET_ACCESS_KEY'] = 'password'
# Set username and password for added authentication
#os.environ['MLFLOW_TRACKING_URI '] = 'https://localhost:5043/'
#os.environ['MLFLOW_TRACKING_USERNAME '] = 'user'
#os.environ['MLFLOW_TRACKING_PASSWORD '] = 'password'
#os.environ['MLFLOW_TRACKING_SERVER_CERT_PATH'] = 'path/to/nginx/auth/domain.pem'
#os.environ['MLFLOW_TRACKING_CLIENT_CERT_PATH'] = 'path/to/nginx/auth/domain.pem'
# MLflow enviroment
remote_server_uri = "https://user:password@localhost:5043/" # set to your server URI
mlflow.set_tracking_uri(remote_server_uri)

mlflow.set_experiment("MLflow_demo")

错误：

MlflowException: API request to https://user:password@localhost:5043/api/2.0/mlflow/experiments/list failed with exception HTTPSConnectionPool(host='localhost', port=5043): Max retries exceeded with url: /api/2.0/mlflow/experiments/list?view_type=ALL (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate (_ssl.c:1108)')))

在阅读文档中的一些注释和相关问题后，我接下来尝试了

# Setting the requried environment variables
os.environ['MLFLOW_S3_ENDPOINT_URL'] = 'https://localhost:9000'
os.environ['AWS_ACCESS_KEY_ID'] = 'user'
os.environ['AWS_SECRET_ACCESS_KEY'] = 'password'
# Set username and password for added authentication
#os.environ['MLFLOW_TRACKING_URI '] = 'https://localhost:5043/'
#os.environ['MLFLOW_TRACKING_USERNAME '] = 'user'
#os.environ['MLFLOW_TRACKING_PASSWORD '] = 'password'
#os.environ['MLFLOW_TRACKING_SERVER_CERT_PATH'] = 'path/to/nginx/auth/domain.pem'
os.environ['MLFLOW_TRACKING_CLIENT_CERT_PATH'] = 'path/to/nginx/auth/domain.pem'
# MLflow enviroment
remote_server_uri = "https://user:password@localhost:5043/" # set to your server URI
mlflow.set_tracking_uri(remote_server_uri)

mlflow.set_experiment("MLflow_demo")

错误：

MlflowException: API request to https://user:password@localhost:5043/api/2.0/mlflow/experiments/list failed with exception HTTPSConnectionPool(host='localhost', port=5043): Max retries exceeded with url: /api/2.0/mlflow/experiments/list?view_type=ALL (Caused by SSLError(SSLError(9, '[SSL] PEM lib (_ssl.c:4012)')))

终于

# Setting the requried environment variables
os.environ['MLFLOW_S3_ENDPOINT_URL'] = 'https://localhost:9000'
os.environ['AWS_ACCESS_KEY_ID'] = 'user'
os.environ['AWS_SECRET_ACCESS_KEY'] = 'password'
# Set username and password for added authentication
#os.environ['MLFLOW_TRACKING_URI '] = 'https://localhost:5043/'
#os.environ['MLFLOW_TRACKING_USERNAME '] = 'user'
#os.environ['MLFLOW_TRACKING_PASSWORD '] = 'password'
os.environ['MLFLOW_TRACKING_SERVER_CERT_PATH'] = 'path/to/nginx/auth/domain.pem'
#os.environ['MLFLOW_TRACKING_CLIENT_CERT_PATH'] = 'path/to/nginx/auth/domain.pem'
# MLflow enviroment
remote_server_uri = "https://user:password@localhost:5043/" # set to your server URI
mlflow.set_tracking_uri(remote_server_uri)

mlflow.set_experiment("MLflow_demo")

错误：

MlflowException: API request to https://user:password@localhost:5043/api/2.0/mlflow/experiments/list failed with exception HTTPSConnectionPool(host='localhost', port=5043): Max retries exceeded with url: /api/2.0/mlflow/experiments/list?view_type=ALL (Caused by SSLError(SSLCertVerificationError("hostname 'localhost' doesn't match '*.my-mlflow.com'")))

你能给我一些解决方法的提示吗？

非常感谢！费尔南多....

Answer 1

您可以设置：

os.environ['MLFLOW_TRACKING_INSECURE_TLS'] = 'true'

然后尝试直接从那里获取您的 cert-chain 用于生产。
