Datadog无法发送容器日志

Question

我正在用Ansible设置datadog代理来发送码头容器日志：https://docs.datadoghq.com/agent/basic_agent_usage/ansible/，但是我注意到没有发送任何日志。

下面：https://docs.datadoghq.com/logs/guide/log-collection-troubleshooting-guide/，我首先尝试用openssl s_client -connect intake.logs.datadoghq.com:10516发送一条测试消息，然后用<API_KEY> this is a test message发送一条测试消息，它没有输出任何内容，而且我注意到没有用“关闭”的方式发送日志。如果我检查/var/log/datadog/agent.log，我不会看到清单10516中的任何错误。

如果我检查状态：sudo datadog-agent status

但我没有看到任何解释，为什么码头日志收集是挂起的。我还在/var/lib/docker/上做了chmod 745，在/var/lib/docker/containers上做了744。

检查错误sudo cat /var/log/datadog/agent.log | grep ERROR：(pkg/forwarder/worker.go:184 in process) | Error while processing transaction: error while sending transaction, rescheduling it: Post "https://7-38-1-app.agent.datadoghq.com/api/v1/series?api_key=<api_key>": dial tcp [2600:1f18:24e6:b901:1af8:1d45:efec:931d]:443: connect: network is unreachable

我在这里找不到一个解释，为什么网络是不可及的，然而。

API_KEY是有效的，因为它正在将其他指标上载到仪表板上，但是我没有看到码头容器日志。

我的不可接受的配置是：

    - role: datadog.datadog
      become: true
      vars:
        datadog_api_key: "{{ logs_datadog_api_key }}"
        #datadog_site: "datadoghq.com"
        datadog_config:
          tags:
            - "env:{{ datadog_environment }}"
            # tags
          log_level: INFO
          logs_config:
            container_collect_all: true
            use_http: true
          apm_config:
            enabled: true
          logs_enabled: true
        network_config:
          enabled: true

我也尝试过将use_http设置为true，但仍然没有发送任何内容。是我错过了什么，还是做错了什么？我是否应该将datadog代理作为一个容器化实例运行？

最后，我找不到为什么端口不能打开，为什么容器日志被挂起。我确实将本地配置更新为：

- name: Install docker python package
  ansible.builtin.pip:
    name: docker

- name: Pull Datadog agent image
  community.docker.docker_image:
    name: "datadog/agent"
    tag: "latest"
    source: pull

- name: Get current agent container
  docker_container_info:
    name: "dd_agent"
  register: result

- name: Stop agent container if running
  docker_container:
    name: "dd_agent"
    state: stopped
  when: result is defined and result.exists

- name: Remove agent container if running
  docker_container:
    name: "dd_agent"
    state: absent
  when: result is defined and result.exists

- name: Run Datadog agent container
  docker_container:
    env:
      DD_API_KEY: "{{ api_key }}"

      DD_APM_ENABLED: "false"
      DD_DOGSTATSD_NON_LOCAL_TRAFFIC: "false"
      DD_PROCESS_AGENT_ENABLED: "true"
      DD_CONTAINER_EXCLUDE: "name:datadog-agent"
    image: "datadog/agent:latest"
    name: "dd_agent"
    restart_policy: "unless-stopped"
    state: started
