我正在尝试为一个苗条的应用程序创建一个docker映像。我使用的苗条应用程序只是TypeScript启动的苗条模板。我没有对应用程序本身进行任何更改，我唯一的目标是使用Docker为苗条的应用程序服务。我使用yarn berry(v2(作为我的包管理器，并使用rollupjs进行构建过程。这是我的第一个问题，如果有什么遗漏，请告诉我。
我期望图像被构建，但是当构建过程达到"；纱线构造"；命令，它永远不会完成。它也没有崩溃，但也从未完成构建步骤。它似乎停留在捆绑步骤：
=> => # src/main.ts → public/build/bundle.js...
package.json中的build命令："build": "rollup -c"
我的Dockerfile最初是从这里获取的：https://sveltesociety.dev/recipes/publishing-and-deploying/dockerize-a-svelte-app/.然而，我不得不对yarn v2进行一些更改，我发现了以下堆栈线程：在Docker映像中使用yarn 2(Berry(进行包装应用程序。添加一些修改表单给我留下了以下Dockerfile：
WORKDIR /app
COPY package.json ./
RUN yarn set version berry
COPY .yarn ./.yarn
COPY yarn.lock .yarnrc.yml ./
RUN yarn plugin import workspace-tools
RUN yarn workspaces focus -A --production
COPY . ./
RUN yarn build # This is where it gets stuck
FROM nginx:1.19-alpine
COPY --from=build /app/public /usr/share/nginx/html
我运行命令docker build -t svelte-image .来构建，这是我得到的输出：

我一直在试图弄清楚构建挂起的原因，但我找不到错误的来源。当使用纱线构建本地构建时，它工作得很好。有人知道它为什么挂在捆绑过程中吗？
我不知道出了什么问题，但我成功地构建了docker映像并运行了它。这是正在工作的Dockerfile:
FROM node:16 AS build
WORKDIR /app
COPY package.json ./
RUN yarn set version berry
COPY .yarn ./.yarn #
COPY yarn.lock .yarnrc.yml ./
RUN yarn install
# These two lines are from the original example. It did not work to use this,
# but I leave it here to highlight the difference
## RUN yarn plugin import workspace-tools
## RUN yarn workspaces focus -A --production
COPY . ./
RUN yarn build
FROM nginx:1.19-alpine
COPY --from=build /app/public /usr/share/nginx/html
