Question

我有Golang应用程序，它使用Logrus将日志写入Stdout。我正在尝试重新创建此https://github.com/DataDog/docker-compose-example场景，并用我的应用替换python应用。但是日志并没有发送到Datadog dashboad 这是docker-compose，我正在尝试工作

version: "3"
services:
  gos:
    build: goapp
    stdin_open: true
    ports:
      - "6000:6000"
    volumes:
      - /tmp/goapp:/tmp/goapp
      - ./goapp:/code
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      - DATADOG_HOST=datadog
  web:
    build: web
    command: python app.py
    ports:
     - "5000:5000"
    volumes:
     - ./web:/code # modified here to take into account the new app path
    links:
     - redis
    environment:
     - DATADOG_HOST=datadog # used by the web app to initialize the Datadog library
  redis:
    image: redis
  # agent section
  datadog:
    build: datadog
    links:
     - redis # ensures that redis is a host that the container can find
     - web # ensures that the web app can send metrics
    environment:
     - DD_API_KEY=34f-------63c
    volumes:
     - /var/run/docker.sock:/var/run/docker.sock
     - /proc/:/host/proc/:ro
     - /sys/fs/cgroup:/host/sys/fs/cgroup:ro

我还通过此https://docs.datadoghq.com/logs/log_collection/docker/?tab=containerinstallation说明尝试为代理安装非组成但简单的docker容器。

我使用以下命令运行golang应用程序容器

docker run -v /var/run/docker.sock:/var/run/docker.sock:rw -d testgo

使用Dockerfile

FROM golang:1.7.3
WORKDIR /go/src/github.com/alexellis/href-counter/
RUN go get -d -v github.com/Sirupsen/logrus
COPY app.go .
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o app .

FROM alpine:latest  
RUN apk --no-cache add ca-certificates
WORKDIR /root/
COPY --from=0 /go/src/github.com/alexellis/href-counter/app .
EXPOSE 6000
LABEL "com.datadoghq.ad.logs"='[{"source": "goapp", "service": "webapp"}]'
CMD ["./app"]

和DD代理可以看到应用程序容器的起伏，但没有收到日志

Answer 1

在我看来，您似乎在docker-compose main_container { display: flex; width: 100%; height: 100%; align-items: center; justify-content: center; flex-direction: row; border: 1px solid #DDDDDD; border-bottom: 1px solid #DDDDDD; text-align: left; .div_2 { width: 90%; }服务配置中缺少几个环境变量。还有添加用于从Docker套接字跟踪日志的注册表的卷。如果没有，也许可以尝试这样的事情？

datadog

从那里开始，如果仍然遇到麻烦，则可能需要联系support@datadoghq.com寻求帮助。他们很快就会回复。

DataDog Docker代理无法从应用程序容器接收日志
