AWS Application Load Balancer中的Eureka服务器运行状况检查失败(Eureka server health check fails in AWS Application Load Balancer)

我在ECS集群中配置了eureka服务器,并为其服务使用了应用程序负载均衡器。 eureka配置为使用属性文件接受身份验证,如下所示。

security.user.name=xxxxx
security.user.password=yyyy

在负载均衡器中,我在端口8761上为eureka创建了一个目标组。我给了健康检查的'/'url。 但负载均衡器的运行状况检查失败,并出现以下错误。

Health checks failed with these codes: [401]

这指定ALB由于身份验证而无法通过运行状况检查。 (删除身份验证部分可以工作,但会导致其他一些错误)。 有没有办法通过ALB的健康检查?


I have configures a eureka server in ECS cluster, and used an application load balancer for it's service. The eureka is configured to accept authentication using the property file as below.

security.user.name=xxxxx
security.user.password=yyyy

In the load balancer i created a target group for eureka on port 8761. And i gave the '/' url for the health check. But the load balancer's health check fails with the following error.

Health checks failed with these codes: [401]

This specifies that the ALB fails to pass the health check because of the authentication. (Removing the authentication part works but it causes some other errors). Is there a way to pass the health check in ALB ?

这是我在评论中提到的方式:它使用文件对象来跳过您在开始时需要跳过的自定义脏数据。 您将文件偏移量放在文件中的适当位置,其中read_fwf只是完成工作:

with open(rawfile, 'r') as data_file:
    while(data_file.read(1)=='#'):
        last_pound_pos = data_file.tell()
        data_file.readline()
    data_file.seek(last_pound_pos)
    df = pd.read_fwf(data_file)

df

This is the way I'm mentioning in the comment: it uses a file object to skip the custom dirty data you need to skip at the beginning. You land the file offset at the appropriate location in the file where read_fwf simply does the job:

with open(rawfile, 'r') as data_file:
    while(data_file.read(1)=='#'):
        last_pound_pos = data_file.tell()
        data_file.readline()
    data_file.seek(last_pound_pos)
    df = pd.read_fwf(data_file)
