如何强制 Docker 使用 bash 而不是 sh 运行我的脚本

如何强制 Docker 使用 bash 而不是 sh 运行我的脚本

这是我的脚本：

#!/bin/bash

# some bash code here

这是我的Dockerfile：

FROM node:lts-bullseye-slim
COPY . .
RUN /Script.sh

这是我得到的错误：

Step 5/5 : RUN /Script.sh
 ---> Running in 09bbdebbc3d7
/Script.sh: line 25: syntax error: unexpected end of file
The command '/bin/sh -c /Script.sh' returned a non-zero code: 2

但是，如果我以交互模式运行容器并使用docker exec -it container_name bash并运行脚本输入它，它就会起作用。

我认为它在构建过程中失败是因为 Docker 想要使用sh而不是bash.

如何强制 Docker 使用 bash，而不是 sh？

更新

这是我真正的脚本，它的真实名称是BuildScript，它没有扩展名，它位于根目录中，并且具有 777 权限：

#!/bin/bash

function RemoveDevelopmentItems()
{
    echo "Removing development items ..."
    rm -rf ${RepositoryPath}/Host
}

function BuildDirectories()
{
    echo "Building directories ..."

function CopyCommon()

function CopyDependencies()
{

    find /HolismPanel -mindepth 1 -maxdepth 1 -not -name Infra |
    while read DependencyPath;
    do
        DependencyName=$(basename $DependencyPath);
        if [[ ${Repository} == *Admin* ]]; then
            mkdir -p ${RepositoryPath}/src/$DependencyName
            cp -a /HolismPanel/$DependencyName/Admin/* ${RepositoryPath}/src/$DependencyName
        fi
    done
}

function MoveMainRepoFiles()
{
    echo "Moving main repo files ..."
    mv ${RepositoryPath}/Menu.jsx ${RepositoryPath}/src/Menu.jsx
    mv ${RepositoryPath}/Routes.jsx ${RepositoryPath}/src/Routes.jsx
    mv ${RepositoryPath}/HeaderActions.jsx ${RepositoryPath}/src/HeaderActions.jsx
    find ${RepositoryPath} -mindepth 1 -maxdepth 1 -type d -not -name src -not -name public |
    while read MainRepoDirectory;
    do
        mv $MainRepoDirectory ${RepositoryPath}/src
    done
}

function LinkNodeModules()
{
    echo "Linking node_modules ..."
    ln -s /HolismPanel/Infra/node_modules ${RepositoryPath}
}

RemoveDevelopmentItems
BuildDirectories
CopyCommon
CopyBase
CopyDependencies
MoveMainRepoFiles
LinkNodeModules

并且请不要告诉我您应该添加扩展名，或者不创建 777 文件，或者不在根目录中工作。谢谢。

RUN /Script.sh是指令的 shell 形式RUN，它将执行/bin/sh -c <command>.要直接执行脚本，请使用执行数组形式改为：RUN ["/Script.sh"].确保您的脚本可执行（运行chmod +x Script.sh）。也不要使用根目录作为工作目录。
