无法通过 docker 构建安装纱线包

Question

我正在尝试通过将yarn.lock中的所有当前软件包都安装在映像上来加速docker的启动。我认为我的纱线安装不正确，它在其他地方工作？

Docker文件的相关部分：

# Create a dir
WORKDIR /(WORKDIR)
# Time to install all our dependencies
COPY package.json /(WORKDIR)/package.json
COPY yarn.lock /(WORKDIR)/yarn.lock
# Need the executables to be in the path
ENV PATH /(WORKDIR)/node_modules/.bin:$PATH
RUN yarn check --verify-tree || yarn install --frozen-lockfile

我认为我的最后一行不正确。它正在某处安装，但不安装在软件包本身上？无论是缓存还是缓存都可能是一个问题。如果我启动图像，我发现yarn check --verify-tree的输出仍然是图像的当前状态。

我在 Docker 构建期间无法yarn install。我收到网络错误(getaddrinfo EAI_AGAIN(：

我最近更新了我的Ubuntu Linux系统，并认为这可能是原因。因此，我重新启动了docker.service并解决了问题。

sudo systemctl restart docker.service

只需RUN yarn并确保COPY代码库yarn.

FROM        node:12.14.0-alpine3.11
ENV         NODE_ENV=production
WORKDIR     /app
COPY        package.json ./
COPY        yarn.lock ./
RUN         yarn
COPY        src ./

我在我的机器上测试它，你可以看看我是否改变了yarn.lock.如果我不改变我的yarn.lock
