Docker and Angular prod `file does not exist` Error on stage build COPY command

问题

我不明白为什么Docker无法在容器中获取我的Angular构建文件夹。
你能看到以帮助我吗？

如果我使用Docker Compose命令构建，我会遇到这个错误。
以下是构建我的镜像并启动容器直到出错的所有步骤。

  1. 警告：您正在使用的Docker引擎正在以Swarm模式运行。
  3. Compose不使用Swarm模式将服务部署到Swarm中的多个节点。所有容器将安排在当前节点上。
  5. 要在整个Swarm中部署应用程序，请使用`docker stack deploy`。
  7. 构建 linking-front
  8. 将构建上下文发送到Docker守护程序 425.6MB

  11. COPY nginx.conf /etc/nginx/nginx.conf
  12. COPY --from=build /usr/src/app/dist/linkingEducationSecurity-front /usr/share/nginx/html

我还使用了Docker Compose。

  1. version: '3.9'
  3. services:
  5.   linking-front:
  6.     build: ./linkingEducationSecurity-front/
  7.     ports:
  8.       - "8080:80"
  9.     volumes:
  10.       - type: bind
  11.         source: ./linkingEducationSecurity-front/src/
  12.         target: /app/src

i do not understand why docker cannot get my angular build folder in container.
Can you see that to help me?

Docker 和 Angular 生成阶段 `file does not exist` 错误在构建阶段的COPY命令

If i build with docker compose command i have this error.
Below are all the steps to build my image and launch my container until the error.

  1. WARNING: The Docker Engine you're using is running in swarm mode.
  3. Compose does not use swarm mode to deploy services to multiple nodes in a swarm. All containers will be scheduled on the current node.
  5. To deploy your application across the swarm, use `docker stack deploy`.
  7. Building linking-front
  8. Sending build context to Docker daemon  425.6MB

I use also docker-compose

  1. version: '3.9'
  3. services:
  5.   linking-front:
  6.     build: ./linkingEducationSecurity-front/
  7.     ports:
  8.       - "8080:80"
  9.     volumes:
  10.       - type: bind
  11.         source: ./linkingEducationSecurity-front/src/
  12.         target: /app/src

得分: 1

由于您在评论中尝试执行 RUN cd dist && ls，导致您得到了以下输出：

  1. Step 7/10 : RUN cd dist && ls  ---> Running in e8f002e82f3a linking-education-security-front

步骤和 Dockerfile 部分是完美的。从构建文件夹中复制的 COPY 命令拼写错误。

请将这行代码更新为：

  1. COPY --from=build /usr/src/app/dist/linking-education-security-front /usr/share/nginx/html

尝试重新构建，这可能会起作用。

英文:

since in the comments you tried to do RUN cd dist && ls which gave you this output :

  1. Step 7/10 : RUN cd dist && ls  ---> Running in e8f002e82f3a linking-education-security-front

The steps and dockerfile are perfect. the COPY command from build folder is missing its spell

update this line :

  1. COPY --from=build /usr/src/app/dist/linkingEducationSecurity-front /usr/share/nginx/html

to this :

  1. COPY --from=build /usr/src/app/dist/linking-education-security-front /usr/share/nginx/html

and try rebuilding , this might work.
