无法从 Docker 容器内访问以太网摄像头

user10627299 2月前

操作系统：Ubuntu 22.04.4 LTSPylon：pylon_7.5.0.15658-deb0_amd64 摄像头连接到以太网接口 enp0s31f6，该接口位于静态 ip 192.168.2.10/255.255.255.0 上。摄像头位于静态 ip 192....

操作系统：Ubuntu 22.04.4 LTS
塔：pylon_7.5.0.15658-deb0_amd64

摄像机连接到以太网接口， enp0s31f6 该接口使用静态 IP 192.168.2.10/255.255.255.0 。摄像机使用静态 IP 192.168.2.11/255.255.255.0 .

我构建了 pylon-ros-camera ，它成功检测到了相机enter image description here

但是，即使我成功地在 Docker 容器内构建了相同的包，它也无法检测到摄像头。

我尝试过

  • 为了让容器能够看到主机上的接口，我以网络方式运行容器 docker run --network=host -d myimage ... 。现在，如果我 ifconfig 在容器内运行，它会显示与主机上相同的接口。请参见 ifconfig 主机和容器内的输出。但是，它仍然无法检测到摄像头。
  • 我以扩展权限运行了容器 docker run --network=host --privileged -v /dev:/dev -d ... 。但是，它仍然无法检测到相机。

可能存在什么问题？

    今天早些时候，我试图设置一个包含几个不同服务的 docker compose 文件，其中一个正在运行 nginx:latest 。我的其他服务之一正在运行 alpine:latest ，无论我怎么尝试，我都无法成功地从 alpine 容器中 curl nginx 服务，并且一直看到 Failed to connect to nginx port 80 curl 错误。从运行其他镜像的容器中 curl nginx 服务似乎没问题。

    为了尝试重现该问题，我 docker-compose.yml 尽可能地减少了文件，并得出了以下结论： 

    services:
  alpine-test:
    build:
      dockerfile: Dockerfile.alpine
    command: sleep 3600
    networks:
      - test-network
  ubuntu-test:
    build: 
      dockerfile: Dockerfile.ubuntu
    command: sleep 3600
    networks:
      - test-network
  nginx:
    image: nginx:latest
    ports:
      - "8080:80"
    networks:
      - test-network
networks:
  test-network:
    driver: bridge

    Dockerfile.ubuntu ： 

    FROM ubuntu:latest

RUN apt update -y && apt install -y curl

    Dockerfile.alpine ： 

    FROM alpine:latest

RUN apk update && apk add curl

    我正在用以下命令启动撰写项目：

    docker compose -f docker-compose.test.yaml up --force-recreate

    从 ubuntu 服务 curl nginx 服务：

    docker exec proj-local-ubuntu-test-1 curl -vv http://nginx

    ubuntu 和 alpine 容器中的文件看起来完全相同，大概是因为 docker 生成了它们 resolv.conf ：

    Ubuntu resolv.conf

    而 nslookup ubuntu 容器中的输出更符合我的预期：

    任何帮助都将不胜感激。谢谢。
