如何使用 alpine 镜像在 Docker 容器中运行单元测试并保存结果？

Question

I am currently located within my folder of the vue.js project. The source files are located in ./src/ folder and test files are located within ./tests/

Usually to run unit tests locally I run the following commands:

npm install
npm ci
npm run test:ci

and it produces, among the others ./report/coverage.lcov file

However, I want to use node:12-alpine docker image to run unit tests inside of it. DO NOT offer to use Dockerfile. I want to run it using docker run --rm node:12-alpine .... and copy the content of ./report folder into my local folder when docker run command is complete. However, I could not figure out how I can do that? What docker run arguments I should use?

Answer 1

为什么机器人在运行时将您的报告目标挂载为一个卷？

Answer 2

I am able to run it locally by creating script.sh file

cd /tmp/run
npm install
npm ci
npm run test:ci

in project directory and running:

docker run --rm -v ${PWD}/:/tmp/run -u 0 node:12-alpine sh /tmp/run/script.sh

This is great as I do not need to install another node version locally and container is deleted after run... However, I could not replace the last line via: cd /tmp/run && npm install ... as it raised an error. Did not really wanted to introduce an extra script. Using --entrypoint outputs another error.

Answer 3

是的，我可以做到，而且很简单

docker run --rm -v ${PWD}/:/tmp/run -u 0 --workdir=/tmp/run node:14-alpine npm install && npm ci && npm run test:ci
