Question

我已按照https://github.com/discordianfish/nginx_exporter中的步骤为 nginx导出程序设置docker容器。

现在我想在mesosphere集群上使用marathon为nginx安装docker容器。如何向docker容器提供参数'nginx.scrape_uri'。我尝试使用此链接中的“特权模式和任意Docker选项”中给出的“参数”原语https://mesosphere.github.io/marathon/docs/native-docker.html但是，在JSON中添加参数原语会使应用程序停留在“部署”状态。

我用于使用marathon为nginx-exporter创建app的我的JSON文件是：

{
  "id": "/nginx-exporter",
  "instances": 1,
  "cpus": 0.1,
  "mem": 25,
  "constraints": [["hostname", "UNIQUE"]],
  "acceptedResourceRoles": ["slave_public"],
  "container": {
    "type": "DOCKER",
    "docker": {
        "image": "fish/nginx-exporter",
        "network": "BRIDGE",
        "portMappings": [
                           {
                              "containerPort": 9113,
                              "hostPort": 9113,
                              "protocol": "tcp"
                           }
                        ],
        "parameters":   [   {"key": "nginx.scrape_uri", "value": "http://52.76.26.53:8080" }
                        ]
              }
  },
  "healthChecks": [{
    "protocol": "TCP",
    "gracePeriodSeconds": 600,
    "intervalSeconds": 30,
    "portIndex": 0,
    "timeoutSeconds": 10,
    "maxConsecutiveFailures": 2
  }]
}

请告诉我将参数'nginx.scrape_uri'添加到JSON文件的正确方法。感谢。

你应该使用＆＃34; args＆＃34;而不是＆＃34;参数＆＃34;，类似于：

{
  ...
  "container": {
    "type": "DOCKER",
    "docker": {
      "image": "fish/nginx-exporter",
      "network": "BRIDGE",
      "portMappings": [
        {
          "containerPort": 9113,
          "hostPort": 9113,
          "protocol": "tcp"
        }
      ]
    }
  },
  "args": [ "-nginx.scrape_uri", "http://52.76.26.53:8080" ],
  ...
}

请记住，您需要启用nginx存根状态模块并将导出器指向该端点：http://nginx.org/en/docs/http/ngx_http_stub_status_module.html
