docker-compose 构建失败，未找到文件

Question

我想问一个关于 docker-compose.yml 和 Dockerfile 的问题。以下是我遇到的情况。

我先用docker image build (docker image build -t test .) and docker 运行 (docker 运行 -p 8888:8080 -p 8889:8009 8883:8443 -v tomcat8:/usr/local/tomcat8 --name test test) 来测试我的 Dockerfile 是否准备就绪，并且它正在工作。

Docker 文件

FROM ubuntu:latest

ENV HOME /usr/local/tomcat8

RUN apt-get -y update && apt-get -y install unzip wget openjdk-8-jdk

COPY ./installERDDAP.sh $HOME/installERDDAP.sh

COPY . $HOME/

RUN chmod +x $HOME/installERDDAP.sh

WORKDIR $HOME

RUN ./installERDDAP.sh

EXPOSE 8080 8443 8009

CMD ["catalina.sh","run"]

所以我编写 docker-compose.yml 的脚本，如下所示

docker-compose.yml

version: '3'

services:
   erddap:
      build:
         context: ./
         dockerfile: Dockerfile
      image: erddap_dev:2.02
      container_name: erddap
      restart: always
      ports:
         - "8888:8080"
         - "8883:8443"
         - "8889:8009"
      volumes:
         - ./tomcat8:/usr/local/tomcat8

但是，弹出错误信息说文件catalina.sh不存在。当我进入容器时，嗯，那是真的。不存在任何文件。但是，如果我将 RUN ls -la 放入 Dockerfile，我会看到文件已列出，如下所示。

有趣的是，这些文件并没有出现在我的卷目录中。请有人告诉我我哪里错了吗？

谢谢

第一次更新：

按照下面的建议，如果我推荐了docker-compose.yml内的卷或者我加了WORKDIR /在CMD命令前面，none个正在工作。
如果我在 Dockfile 中从 CMD ["catalina.sh","运行" 修改了 CMD 命令] 到 CMD ["./catalina.sh","运行"] 也不起作用。但是如果我改为 CMD ["/usr/local/tomcat8/catalina.sh","运行"]，构建过程就完成了。但是错误比变成

第二次更新：

installERDDAP.sh

#!/bin/bash
mkdir tarz

wget -q https://ftp.wayne.edu/apache/tomcat/tomcat-8/v8.5.57/bin/apache-tomcat-8.5.57.tar.gz -O ./tarz/apache-tomcat-8.5.57.tar.gz
tar -xf ./tarz/apache-tomcat-8.5.57.tar.gz -C /usr/local/tomcat8 --strip 1


mkdir data

ln ./bin/catalina.sh catalina.sh

Answer 1

在你的 docker 文件中，在行 CMD ["catalina.sh","run"] 之前放置 WORKDIR / 并将“catalina.sh”更改为“./catalina.sh”

Answer 2

据我所知，您的绑定挂载可能是“overriding/hiding”您的容器文件。如果你的“./tomcat8”目录不为空，它基本上会“override/hide”你容器中的文件。我会删除卷声明以验证是否是这种情况，如果是这样，那么您将需要清除您的“./tomcat8”目录，当您再次运行容器时，它应该用文件填充它容器，从那时起您的本地目录将再次“override/hide”您的容器文件。
