Question

尝试运行docker容器时出现以下错误：

Error: Unable to access jarfile

我的Dockerfile是这样的：

FROM ubuntu:16.04

# Install Updates
RUN apt-get update -y && \
     apt-get upgrade -y && \
     apt-get install -y software-properties-common && \
     apt-add-repository -y ppa:openjdk-r/ppa && \
     apt-get update -y && \
     rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /var/cache/*

# Install Packages
RUN apt-get -qq update -y && \
    apt-get -q install -y \
        wget \
        openssh-server \
        openjdk-8-jdk \
        && \
    apt-get clean && \
    rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /var/cache/*

# Add the config files
ADD /apps/ /home/smartling/

# Adding the jar application
ADD /apps/flagship/repo-connector-1.5.4/repo-connector-1.5.4.jar /home/smartling/flagship/repo-connector-1.5.4/

# Making sure the files are there
RUN ls -la /home/smartling/flagship/repo-connector-1.5.4/

# Start the jar file when container launches
CMD ["java","-jar","/home/smartling/flagship/repo-connector-1.5.4/repo-connector-1.5.4.jar -start&"]

然后我建立

docker build -t smartlingflagship .

一切都恢复成功

我运行容器

docker run --rm --name smartlingconn smartlingflagship

它返回时出现以下错误：

Error: Unable to access jarfile /home/smartling/flagship/repo-connector-1.5.4/repo-connector-1.5.4.jar -start&

我错过了什么吗？

Answer 1

我可以通过将其添加到底部ENTRYPOINT ["java","-jar","repo-connector-1.5.4.jar"] CMD ["-start"]

来解决此问题

Answer 2

请你检查一下： “RUN ls -la /home/smartling/flagship/repo-connector-1.5.4 /”

检查文件（repo-connector-1.5.4.jar）是否具有运行所需的权限。如果没有，请使用chmod并授予jar权限。

命令如下：
RUN [“chmod”，“+ x”，“/ home /smartling / flagg / trip-connectionctor.5.5.4 /repo-connector-1.5.4.jar”]

在＃确认文件在那里之后放置上面的命令 RUN ls -la /home/smartling/flagship/repo-connector-1.5.4 /

错误：运行docker容器时无法访问jarfile
