Question

我正试图通过将yarn.lock中的所有当前软件包都安装在映像上来加快docker的速度。我想我做的纱安装不正确，是否在其他地方工作？

dockerfile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是错误的。它安装在某个地方，但不在包装本身上吗？要么是缓存，要么是一个问题。如果启动图像，我发现yarn check --verify-tree的输出仍然是图像的当前状态。

只需RUN yarn，并确保COPY之后是yarn代码库。

FROM        node:12.14.0-alpine3.11

ENV         NODE_ENV=production
WORKDIR     /app

COPY        package.json ./
COPY        yarn.lock ./
RUN         yarn

COPY        src ./

我在机器上对其进行了测试，您可以查看是否更改了yarn.lock。如果我不更改自己的yarn.lock

$ docker build -t demo .
