Docker /docker-entrypoint.sh: 32: exec: yarn: 当 运行 docker 容器 (Angular) 时找不到

Question

我正在尝试在 docker 容器中构建一个 angular 应用程序。我成功构建了一个 docker 图像并从中创建了一个容器，但是当我 运行 它时，我得到 /docker-entrypoint.sh: 32: exec: yarn: not found。这是我的 Dockerfile：

FROM node:13.3.0 AS compile-image
RUN npm install -g yarn
WORKDIR /opt/ng 
COPY package.json yarn.lock angular.json ./
RUN yarn
RUN yarn install
COPY . ./ 
RUN node_modules/.bin/ng build --prod
FROM nginx
COPY --from=compile-image /opt/ng/dist/dashboard /usr/share/nginx/html
CMD ["yarn", "start"]

据我所知，Run yarn 失败了，但我很困惑为什么 RUN npm install -g yarn 应该安装它。我是 docker 的新手，很抱歉，如果我得出错误的结论。

Answer 1

请使用 nginx:1.18-alpine 并从包管理器安装 yarn npm install -g yarn

FROM node:13.3.0 AS compile-image
RUN npm install -g yarn
WORKDIR /opt/ng 
COPY package.json yarn.lock angular.json ./
RUN yarn
RUN yarn install
COPY . ./ 
RUN node_modules/.bin/ng build --prod
FROM nginx:1.18-alpine
RUN apk add yarn
COPY --from=compile-image /opt/ng/dist/dashboard /usr/share/nginx/html
CMD ["yarn", "start"]

Also, make sure that you change to your requirements.
