Question

我是Docker的新手，想在我的容器中安装nginx以便在外部ip上进行重定向

我的目标是向http://localhost:3010/api/v1/service发送请求在docker中，它应该将我重定向到我的http://192.168.99.1:3010/api/v1/service

http://192.168.99.1:3010 -it my rails server running

或许我的想法完全错了？

我尝试RUN yum install nginx，但我有

ERROR: Service 'my_service_name' failed to build: The command '/bin/sh -c yum install nginx' returned a non-zero code: 1

dockerfile

您的问题是您没有将nginx存储库添加到容器中。在运行yum install nginx之前尝试添加此步骤 RUN yum -y install epel-release

两个额外提示 - 1.使用-y标志安装yum软件包，否则它们将因缺少用户输入而失败。 2.尝试将所有程序包安装命令放在一个RUN命令中，以减少映像中的图层。例如，我会把Nginx当作你当前的Dockerfile -

RUN yum -y install wget && \
    wget https://github.com/papertrail/remote_syslog2/releases/download/v0.15/remote_syslog_linux_amd64.tar.gz && \
    tar xzf ./remote_syslog*.tar.gz && \
    cd remote_syslog && \
    cp ./remote_syslog /usr/local/bin && \
    yum -y install postgresql \
    yum -y install epel-release && \
    yum -y install nginx && yum clean all
