测试shinyproxy-demo时启动容器失败

问题描述 投票：0回答：1

我是shinyproxy的新手，所以我要开始向向导学习https://www.shinyproxy.io/documentation/

我遵循了所有说明，我成功访问了

localhost:8080
但是，我无法访问该应用程序，就像这样。

但是我继续按照向导构建了

shinyproxy-template
图像，运行
docker run -it -p 3838:3838 openanalytics/shinyproxy-template
，效果很好，然后我手动添加了
applicaiton.yml
文件，在使用shinyproxy时也会出现同样的问题。

我在google或stackoverflow都找不到和我一样的情况，所以向大家求助！

您的设置中似乎存在与 Docker 连接相关的问题。主要错误消息是：

Caused by: com.spotify.docker.client.exceptions.DockerException: java.util.concurrent.ExecutionException: javax.ws.rs.ProcessingException: org.apache.http.conn.HttpHostConnectException: Connect to localhost:2375 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: no further information

这表明 ShinyProxy 无法连接到您系统上的 Docker。以下是您可以检查和解决的一些事项：

  1. Docker 守护进程运行： 确保 Docker 守护进程正在您的计算机上运行。 ShinyProxy 需要与 Docker 通信来启动容器。

  2. Docker 主机配置： ShinyProxy 正在尝试连接到 localhost:2375 上的 Docker。确保 Docker 配置为接受远程连接。如果您在本地运行 Docker，则可能需要将 Docker 守护进程公开为 TCP 服务。您可以通过修改 Docker 守护进程配置（通常位于 

    /etc/docker/daemon.json
    ）来完成此操作，以包括：

{
  "hosts": ["tcp://0.0.0.0:2375", "unix:///var/run/docker.sock"]
}

修改 Docker 守护进程配置后，重新启动 Docker 守护进程。

  1. Docker 套接字权限：

确保运行 ShinyProxy 的用户具有访问 Docker 套接字所需的权限。您可能需要将用户添加到 

docker
组。

sudo usermod -aG docker $USER

进行此更改后，您可能需要注销并重新登录或重新启动系统才能使更改生效。

  1. 检查 Docker 连接性：

通过在终端中执行以下命令来验证 Docker 是否正在运行且可访问：

docker info

如果此命令失败，则可能表明 Docker 本身存在问题。

  1. 防火墙设置：

确保没有防火墙规则阻止 ShinyProxy 和 Docker 之间的通信。
