docker-compose 未将文件复制到 tmp 文件夹以创建容器

Question

I have a container for a Telegram bot running in a docker container which is being built via following Dockerfile:

FROM debian:stretch
RUN apt-get -qq update && apt-get -qq install -y g++ make binutils cmake libssl-dev libboost-sysstem-dev libcurl4-openssl-dev zlib1g-dev
WORKDIR /usr/src/tgbot-cpp
COPY include include
COPY src src
COPY CMakeLists.txt ./
RUN cmake .
# ...

The Dockerfile is placed in /home/me/docks/tbot/Dockerfile .

However, now when I want to organize the files a bit, ie, put the include , src , and CMakeLists.txt into a subfolder called containerBuildFiles (absolute: home/me/docks/tbot/containerBuildFiles ), I do the following:

• call docker-compose down
• edit Dockerfile :

# ...
 [-] COPY include include
 [-] COPY src src
 [-] COPY CMakeLists.txt ./
 [+] COPY containerBuildFiles ./
# ...

• mkdir containerBuildFiles
• mv -t containerBuildFiles include src CMakeLists.txt
• (just to make sure) docker-compose build --no-cache --force-rm --pull

Which gives me following output:

[...]

Step 5/8 : COPY containerBuildFiles ./
ERROR: Service 'tgbot' failed to build: COPY failed: stat /home/docker/tmp/docker-builder654813864/containerBuildFiles: no such file or directory

Now when I'm undoing the changes made in the Dockerfile and in the directory structure, everything is working fine again.

I have also tried changing the path in the Dockerfile from containerBuildFiles to ./containerBuildFiles resp. /home/me/docks/tbot/containerBuildFiles (I know it's bad practice but I wanted to try it) or simply running docker build. -t tbot_test --no-cache docker build. -t tbot_test --no-cache , same results.

My idea was that maybe the docker-compose context is not being updated correctly. Apparently the files from the docker container are not being copied to the /home/docker/tmp folder correctly.

So now my question is: how can I update the docker-compose context so updated folders will be passed to creation of docker containers correctly again?

Any help is greatly appreciated.

Answer 1

Solved it by removing .dockerignore file.

[EDIT] Reason: the .dockerignore file included lines which ignore every folder that was not include , src or the file CMakeLists.txt :

!include
!src
!CMakeLists.txt

so they were not copied.
