Dockerfile build on Google Cloud Build 不打印测试日志

Question

我有一个简单的Dockerfile：

FROM node:8
# Create app directory
WORKDIR /usr/src/app
# Install app dependencies
# A wildcard is used to ensure both package.json AND package-lock.json are copied
# where available (npm@5+)
COPY package*.json ./
RUN npm install
# If you are building your code for production
# RUN npm install --only=production
# Bundle app source
COPY . .
CMD ["npm", "run", "test"]

我在Google Cloud Build中运行它并获取以下日志：

...
Removing intermediate container 19ae183b28c6
---> 5802f218fa4e
Step 5/6 : COPY . .
---> a1600834b6e0
Step 6/6 : CMD npm run test
---> Running in bfb7be511b96
Removing intermediate container bfb7be511b96
---> 6e974d117670
Successfully built 6e974d117670
...

在第6/6步，npm run test，我没有看到我在本地机器上的日志：

npm run test：

PASS  __tests__/order.spec.ts
PASS  __tests__/news.spec.ts
PASS  __tests__/product.spec.ts (5.328s)
PASS  __tests__/review.spec.ts
PASS  __tests__/donation.spec.ts
PASS  __tests__/referral.spec.ts
PASS  __tests__/nonprofit.spec.ts
Test Suites: 7 passed, 7 total
Tests:       22 passed, 22 total
Snapshots:   0 total
Time:        8.291s, estimated 9s

如何让这些日志显示在构建日志中？

Answer 1

这是因为您正在构建映像而不是:)运行它。当您运行容器时，您将看到打印出的日志，例如

docker run -it my-image
