k.Transform failed archive/tar: write too long

[wuestkamp]

When running kompose up -vvv I'm getting:

INFO Building image 'eu.gcr.io/project/php:latest' from directory 'project_dir' 
DEBU Created temporary file /var/folders/yt/9pghpn1s5sq0bvnw0hmwljfr0000gn/T/kompose-image-build-069005223 for Docker image tarballing 
FATA Error while deploying application: k.Transform failed: Unable to build Docker image for service php: Unable to create a tarball: archive/tar: write too long 

I can push manually though without issues using docker push eu.gcr.io/project/php:latest

Why is this a problem here?
What is tarball used for?
Can I disable tarballing?

I saw #656 but is closed so wanted to open a new one. I'm having a Symfony project and removed already the vendor folder, no change.

Thanks,
Kim

So this only happens if I do this in my docker-compose.yml:

    php:
        build:
          context: .
          dockerfile: ./php-fpm/Dockerfile

if I leave it like this no error:

    php:
        build: ./php-fpm

But I need to use the context setting because I want to copy files in my Dockerfile:

ADD php-fpm/symfony.ini /etc/php7/conf.d/
ADD php-fpm/symfony.ini /etc/php7/cli/conf.d/
ADD php-fpm/xdebug.ini  /etc/php7/conf.d/

ADD php-fpm/symfony.pool.conf /etc/php7/php-fpm.d/

CMD ["php-fpm7", "-F"]

WORKDIR /var/www/symfony
COPY symfony .

Anyone got an idea?

Ok, this was because there were still deeply hidden symlinks in the context folder. So symlinks was the issue :)

Sorry for dumb question but I don't get what the issue is with symlinks and what should one do in case he has some (I do) ?

Thanks for your help :)
