Question

我在docker容器中运行.sh脚本时遇到问题。它给了我：

ml_1 | 2018-08-02 08：31：32,680信息产生：'datagrid'   pid为18

ml_1 | 2018-08-02 08：31：32,686信息退出：datagrid   （退出状态为127；不可预期）

ml_1 | 2018-08-02 08：31：38,732信息放弃了：datagrid   进入致命状态，太多的重试开始得太快了

我的脚本：

#!/bin/bash

Answer 1

我在docker容器中运行.sh脚本时遇到问题

这里有很多问题……只是一些提示：

您的配置文件结构有点混乱，来自Dockerfile：

WORKDIR /EscomledML
ADD . /EscomledML
ADD ./MLScripts/lib EscomledML/lib
ADD ./MLScripts/config EscomledML/config
ADD ./MLScripts/config EscomledML/home/escomled/escomled_server/config
ADD ./MLScripts EscomledML/MLScripts

由于脚本期望在其他地方使用，因此不会真正被脚本正确定位：

LIB=/home/escomled/escomled_server/lib
CONFIG=/home/escomled/escomled_server/config

检查所有文件位置，以确认它们已正确放置在应有的位置。

守护进程应作为主要进程在前台启动。由于您首先遇到启动过程中的问题，因此在将其设置为Dockerfile的入口点之前，尝试与/ bin / bash交互地启动容器并正确启动启动脚本。
您正在尝试从一个操作系统迁移到另一个操作系统。安装细节和环境差异可能是您的应用无法正常启动的原因。
您可以直接在docker中使用build args和env变量，以避免在脚本中对其进行初始化。确保所有环境变量均已正确初始化

评论后编辑：

您还遇到multistage build问题...您没有转移到上一阶段的工件，而是有效地将其丢弃。这就是为什么上一阶段之后没有任何文件夹的原因。您需要某种COPY --from=0 ...效果并检查您想要的结果，因为您可能在这里滥用了多阶段构建（主要目的是在上一层作为一次性构建阶段构建某些东西，而不是将两个图像合并为一个）

在下一条评论后编辑：

我的看法是，您使用ubuntu映像的唯一一件事就是安装超级用户。如果是这种情况，则只需替换以下几行：

FROM ubuntu:14.04
RUN apt-get update && apt-get install -y supervisor

具有：

apk add --update supervisor

将在高山映像中安装supervisor，您将很高兴。

请注意，您的目录结构看起来很混乱（首先添加.，然后再添加子文件夹，等等），因此请确保检查一下这些内容。我不知道您想要的目录结构是什么，但是您应该能够在那里建立头...

Answer 2

首先，启动系统服务或后台进程的命令（service，systemctl，initctl，start-stop-daemon等）不起作用在Docker中。

如果您在初始环境变量设置后用在前台运行实际服务器的命令替换了所有脚本

#!/bin/sh
LIB=...
...
ARGS=...
exec ${JAVA} ${ARGS} -classpath "${CLASSPATH}" com.escomled.blackboard.main.DataGridServer

Docker容器将一直运行，直到该服务器进程退出，这是您通常想要的。

sh脚本在docker容器中不起作用
