Solution 1

You should put those files into the same directory with Dockerfile.

Solution 2

Check if there's a .dockerignore file, if so, add:

!mydir/test.json
!mydir/test.py

Solution 3

Q1: Check your .dockerignore file in build path, the files or dir you want to copy may be in the ignore file list!
Q2: The COPY directive is based on the context in which you are building the image, so be aware of any problems with the directory where you are currently building the image! See: https://docs.docker.com/engine/reference/builder/#copy

Solution 4

I had to use the following command to start the build:

docker build .

Solution 5

Removing ./ from source path should resolve your issue:

 COPY test.json /home/test.json
 COPY test.py /home/test.py

I want to create a docker image. This is my work directory: Dockerfile.in test.json test.py

And this is my Dockerfile:
```
COPY ./test.json /home/test.json
COPY ./test.py /home/test.py

RUN python test.py
```
When i launch this command: docker build -f Dockerfile.in -t 637268723/test:1.0 .

It gives me this error:
```
`Step 1/5 : COPY ./test.json /home/test.json
 ---> Using cache
 ---> 6774cd225d60
 Step 2/5 : COPY ./test.py /home/test.py
 COPY failed: stat /var/lib/docker/tmp/docker-builder428014112/test.py: 
 no such file or directory`
```
Can anyone help me?

  Is that from some kind of build system? Or where does the path come from?

  Is test.py or *.py in your dockerignore?

  Is test.py available in current directory where Docker filed exitsts.

  @KlausD. that path looks like what I see docker using internally for building images (e.g., not a build system, it's just docker output when there is a file failure

  Did you ever solve this? Having the same problem.

  Docker still presents buggy behaviors on it's engine, imho. I used the same COPY statement on my Dockerfile, and had the same issues. Tried COPY /host_file /container_folder (without dot), and it worked. After this, tried the former COPY that you have here, and it worked normally (wtf?)! One thing that I made different, was to remove all images (cache) that Docker generates on the build process. My guess, is that trash might be still stored on these intermediary images (I'm using Docker 18.09.5). Take a look on SO or GitHub, SO MANY issues about 'copying host -> container. Bad omen.

  Wow man, ivanleoncz thank you I resolved this problem. I had this clause: ADD mcint_swagger_hub-1.0.0.jar /opt/jboss/wildfly/standalone/deployments/mcint_swagger_hub_‌api-1.0.0.jar and I put a simple slash before the mcint_swagger_hub-1.0.0.jar , so now i got this: ADD /mcint_swagger_hub-1.0.0.jar /opt/jboss/wildfly/standalone/deployments/mcint_swagger_hub_‌api-1.0.0.jar and I have no problem. Thanks bro!! God Bless you

  in my case, it's just because of non-existing file like ./test.py in the folder of Dockerfile

  For me, on Windows, COPY seems to fail if a .dockerignore file even exists and works when I delete .dockerignore, irrespective of the contents of .dockerignore

  This could also happen if you're ignoring all files in .dockerignore using wildcard * but not including specific files you want to be COPYed like his: !file_to_copy.ext

in may case i put them in docker ignore oh no :D

Because I was using 'from python:2.7-onbuild' it copied all the sibling and child files from Dockerfile location anyway. So, I finally removed the COPY lines from Dockerfile and the files being as sibling files were copied too.

@Mugen glad that my comment save your life ;)

Hi, Nishant! It would be worthy to express your solution with more details. Copy files from host to container, is still something tricky on Docker. Please, give examples in order to clarify your answer. Regards :)

This one worked for me, the whole folder was ignored, then docker failed to create the image giving a bad impression driving me mad about the file paths.

Is this a bug? Has someone figured out why this works? This was the only thing that helped

.dockerignore is the root cause for my issue!

My own problem was a little different, but Docker's "issue" with odd paths when referencing a file above the folder containing Dockerfile was the issue THANKS! [Windows 10 + Powershell].

If this doesn't work, check your .dockerignore file!

This worked for me as well. In my case the folder I was referring to was in .dockerignore, so removed from it.

My script part of my gitlab-ci.yml file was: - cd cmd/ZpmHttpServer/ - apk add git - go get - go build -o ../../ZPMOddajaNalog_API. The following part was missing: ../../ which was the reason that the Dockerfile was not in the same directory.

This worked for me, thank you. docker build . --no-cache

THANKS!!! this helped me a lot. I was using docker build - < docker/gpu.Dockerfile but now I tried docker build -f docker/gpu.Dockerfile . and it works perfectly
Daniel over 2 years

This worked for me too, and I'm not sure why it would work and docker build - < Dockerfile wouldn't...
