Project directory

 Dockerfile
 docker/build.sh

This is the two main documents

docker build

docker build -t apps/apps .

There will be an error after execution

Step 8 : RUN docker/build.sh

 The command '/bin/sh -c docker/build.sh' returned a non-zero code: 127

Part of dockerfile

COPY . /app/apps/
 WORKDIR /app/apps/
 RUN ./docker/build.sh

Clearly there is this document under the current project, why did the prompt not find it?

COPY . /app/apps/
 WORKDIR /app/apps/
 RUN /docker/build.sh
