我正在使用以下版本的 docker ...
localhost:client davea$ docker -v
Docker version 19.03.5, build 633a0ea
我有以下 Dockerfile
FROM node:10-alpine AS alpine
WORKDIR /app
# A wildcard is used to ensure both package.json AND package-lock.json are copied
COPY package*.json /app/
## install only the packages defined in the package-lock.json (faster than the normal npm install)
RUN npm install
# Copy the contents of the project to the image
COPY . .
# Run 'npm start' when the container starts.
CMD ["npm", "run", "start"]
然后我像这样构建并运行图像......
localhost:client davea$ docker build --tag client:1.0 .

但是，当我尝试访问我的应用程序时，尽管我尝试在指定的端口上连接，但连接被拒绝...
localhost:client davea$ wget http://localhost:3001
--2020-03-31 20:44:20-- http://localhost:3001/

Connecting to localhost (localhost)|::1|:3001... failed: Connection refused.
Connecting to localhost (localhost)|127.0.0.1|:3001... failed: Connection refused.
我怎么能弄清楚这里出了什么问题？我在我的 Docker 文件构造中没有看到任何明显的缺陷。
编辑：这是在停止的容器上运行“docker logs”的输出......
