[英]Docker compose not properly copying files to run react app
I am trying to run a create-react-app inside of a docker container and automate docker build/run with docker-compose to eventually add other containers like a backend + db.我正在尝试在 docker 容器内运行 create-react-app,并使用 docker-compose 自动化 docker build/run 以最终添加其他容器,如后端 + db。 Running docker-compose in the local folder works properly but setting the context to the folder and running it in the parent directory results in an error.
在本地文件夹中运行 docker-compose 可以正常工作,但是将上下文设置为文件夹并在父目录中运行它会导致错误。
I have tried to get the container to list the current files so I can see if package.json is properly being copied over but ls and bash aren't in path of the node image or container so they won't run properly.我试图让容器列出当前文件,以便我可以查看 package.json 是否被正确复制,但 ls 和 bash 不在节点映像或容器的路径中,因此它们将无法正常运行。
docker-compose.yaml docker-compose.yaml
version: '3.5'
services:
dashboard-serve:
container_name: dashboard
build:
context: ./React-Frontend
dockerfile: Dockerfile
volumes:
- '.:/app'
- '/app/node_modules'
ports:
- '3001:3000'
environment:
- NODE_ENV=development
dockerfile文件
FROM node:12.2.0-alpine
# set working directory
WORKDIR /app
# add `/app/node_modules/.bin` to $PATH
ENV PATH /app/node_modules/.bin:$PATH
# install and cache app dependencies
COPY package.json /app/package.json
RUN npm install
RUN npm install react-scripts@3.0.1 -g
# start app
CMD ["npm", "start"]
It runs and outputs an error that it cannot find package.json它运行并输出找不到 package.json 的错误

You must copy your files into the Docker container.您必须将文件复制到 Docker 容器中。 Currently , you're only copying the
package.json
file.目前,您只复制
package.json
文件。

RUN npm install
RUN npm install react-scripts@3.0.1 -g
# Copy files into Docker container
