ERROR: Build failed: exit code 1

this is because the runner executes:

docker run composer/composer sh -c 'date'
                                   
  [RuntimeException]               
  The "-c" option does not exist.  

the way i see it could be solved, is to reset entrypoint of the image with /bin/sh:

$ docker run --entrypoint /bin/sh composer/composer -c 'date'
Thu Sep  1 09:30:43 UTC 2016

the image itself has defined:

# Set up the command arguments
CMD ["-"]
ENTRYPOINT ["composer", "--ansi"]

@glensc did you in the meanwhile find a solution for this?

@rvanlaak i built custom composer image with entrypoint that can accept shell syntax

#!/bin/sh

case "$1" in
        *sh)
                exec "$@"
                exit 1
        ;;
esac

exec composer --ansi "$@"

# Use run wrapper until this bug is fixed:
# https://gitlab.com/gitlab-org/gitlab-ci-multi-runner/issues/1641
ADD composer.sh /

# Set up the command arguments
ENTRYPOINT ["/composer.sh"]

BTW this seems to be fixed in the official composer image, try it with composer:latest and it works fine :)

build_composer:
    stage: build
    image: composer:latest
    script:
        - composer install --no-dev -o --ignore-platform-reqs

the source repo for composer:latest seems to be here: https://github.com/composer/docker

the solution came via custom entrypoint, like i did: https://github.com/composer/docker/commit/924d20760ef0b3926825c61ad4997e9fd23ce32b https://github.com/composer/docker/commit/dd97b09686b1bfb45ee809874c45c265509b900e

however, this means docker images need to add support so that unknown arguments get passed to (posix or bash) shell

this bug probably needs to be re-titled to be more generic, as it is not just composer image issue...

the solution is imho in #1421 (closed), so closing as the intermediate composer image is usable now
