Question

我一直很难解决我的Docker映像未在本地主机上加载的问题。我正在将Docker用于Windows7。以下是有关我的Docker映像，网络等的一些信息，如果它对提出解决方案有帮助的话。

我的docker文件中有EXPOSE 80。和listen 8080在我的Shinyserver.conf文件中。我通过键入docker run -p 80:8080 imagename来运行图像。它回到命令行。然后我检查http://localhost或http://localhost:8080或http://172.17.0.1或http://172.17.0.1:8080或http://192.168.99.100，但没有图像出现。

当我运行docker ps时，没有正在运行的容器（这是有道理的，因为映像在本地主机上始终没有运行）。所有退出的容器均以docker ps -a显示。有一些我什至没有通过show创建的容器（我猜它是随创建图像而来的）。

我运行docker inspect来找到IP地址，这就是我得到的（fitfarmz上没有IP，这是我的映像名称）

$ docker inspect -f '{{.Name}} - {{.NetworkSettings.IPAddress }}' $(docker ps -aq)

我也在docker网络上获得了信息：

$ docker network inspect bridge
[
    {
        "Name": "bridge",
        "Id": "9105bd8d679ad2e7d814781b4fa99f375cff3a99a047e70ef63e463c35c5ae28"
,
        "Created": "2018-09-08T22:22:51.075519268Z",
        "Scope": "local",
        "Driver": "bridge",
        "EnableIPv6": false,
        "IPAM": {
            "Driver": "default",
            "Options": null,
            "Config": [
                {
                    "Subnet": "172.17.0.0/16",
                    "Gateway": "172.17.0.1"
                }
            ]
        },
        "Internal": false,
        "Attachable": false,
        "Ingress": false,
        "ConfigFrom": {
            "Network": ""
        },
        "ConfigOnly": false,
        "Containers": {},
        "Options": {
            "com.docker.network.bridge.default_bridge": "true",
            "com.docker.network.bridge.enable_icc": "true",
            "com.docker.network.bridge.enable_ip_masquerade": "true",
            "com.docker.network.bridge.host_binding_ipv4": "0.0.0.0",
            "com.docker.network.bridge.name": "docker0",
            "com.docker.network.driver.mtu": "1500"
        },
        "Labels": {}
    }
]

这是dockerfile：

FROM r-base:3.5.0

# Install Ubuntu packages
RUN apt-get update && apt-get install -y \
    sudo \
    gdebi-core \
    pandoc \
    pandoc-citeproc \
    libcurl4-gnutls-dev \
    libcairo2-dev/unstable \
    libxt-dev \
    libssl-dev 


# Add shiny user
RUN groupadd  shiny \
&& useradd --gid shiny --shell /bin/bash --create-home shiny



# Download and install ShinyServer
RUN wget --no-verbose https://download3.rstudio.org/ubuntu-14.04/x86_64/shiny-server-1.5.7.907-amd64.deb && \
    gdebi shiny-server-1.5.7.907-amd64.deb


# Install R packages that are required
RUN R -e "install.packages(c('Benchmarking', 'plotly', 'DT'), repos='http://cran.rstudio.com/')"
RUN R -e "install.packages('shiny', repos='https://cloud.r-project.org/')"

# Copy configuration files into the Docker image
COPY shiny-server.conf  /etc/shiny-server/shiny-server.conf
COPY /app /srv/shiny-server/

# Make the ShinyApp available at port 80
EXPOSE 80

# Copy further configuration files into the Docker image
COPY shiny-server.sh /usr/bin/shiny-server.sh

CMD ["/usr/bin/shiny-server.sh"]

还有Shinyserver.conf：

# Define the user we should use when spawning R Shiny processes
run_as shiny;

# Define a top-level server which will listen on a port
server {
  # Instruct this server to listen on port 80. The app at dokku-alt need expose PORT 80, or 500 e etc. See the docs
  listen 8080;

  # Define the location available at the base URL
  location / {

    # Run this location in 'site_dir' mode, which hosts the entire directory
    # tree at '/srv/shiny-server'
    site_dir /srv/shiny-server;

    # Define where we should put the log files for this location
    log_dir /var/log/shiny-server;

    # Should we list the contents of a (non-Shiny-App) directory when the user 
    # visits the corresponding URL?
    directory_index on;
  }
}

这是Shiny-server.sh文件：

mkdir -p /var/log/shiny-server
chown shiny.shiny /var/log/shiny-server

exec shiny-server >> /var/log/shiny-server.log 2>&1

任何想法出了什么问题？我使用命令：docker run -p 80:8080 fitfarmz来运行图像。

Docker映像未在Localhost上加载。网络等
