【问题描述】：

我正在尝试在 Cent-OS 基础上安装 Kapacitor，但是，当我构建 dockerfile 时，我在执行 localinstall 命令时遇到了问题（或者我认为是这样）。

我的dockerfile如下：

FROM centos-base:7   

ENV CONFIG_HOME /usr/local/bin

RUN curl -O https://dl.influxdata.com/kapacitor/releases/kapacitor-0.13.1.x86_64.rpm

RUN yum localinstall kapacitor-0.13.1.x86_64.rpm 

COPY kapacitor.conf $CONFIG_HOME
ENTRYPOINT["/bin/bash"]

当我构建它时，我得到以下响应：

我哪里错了？我不能在 Dockerfile 中执行 localinstall 吗？谢谢！

标签： docker dockerfile kapacitor

【解决方案1】：

替换

RUN yum localinstall kapacitor-0.13.1.x86_64.rpm

与

RUN yum -y localinstall kapacitor-0.13.1.x86_64.rpm

【讨论】：

谢谢。那行得通。但是，现在，最后一条指令似乎存在一些问题，因为它给出了错误“未知指令：ENTRYPOINT [“/BIN/BASH”]`。我在那里做错了吗？
@RohanSingh 你必须在ENTRYPOINT 和['/bin/bash'] 之间放置一个空格
