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

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。

警告:您正在使用的Docker引擎正在以Swarm模式运行。

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。

要在整个Swarm中部署应用程序,请使用`docker stack deploy`

### 阶段2:运行 ###
FROM nginx:1.23.3-alpine
COPY nginx.conf /etc/nginx/nginx.conf
COPY --from=build /usr/src/app/dist/linkingEducationSecurity-front /usr/share/nginx/html

我还使用了Docker Compose。

version: '3.9'

services:

  linking-front:
    build: ./linkingEducationSecurity-front/
    ports:
      - "8080:80"
    volumes:
      - type: bind
        source: ./linkingEducationSecurity-front/src/
        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.

WARNING: The Docker Engine you're using is running in swarm mode.

Compose does not use swarm mode to deploy services to multiple nodes in a swarm. All containers will be scheduled on the current node.

To deploy your application across the swarm, use `docker stack deploy`.

I use also docker-compose

services:

  linking-front:
    build: ./linkingEducationSecurity-front/
    ports:
      - "8080:80"
    volumes:
      - type: bind
        source: ./linkingEducationSecurity-front/src/
        target: /app/src

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:

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:

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 :

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 :

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

to this :

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

and try rebuilding , this might work.
