Question
Is is the bug that docker appliance does not pass COMPOSE_FILE into docker-compose?

As you see, COMPOSE_FILE is not taken into account. As you run docker-compose via docker using a script:
root@towergame:~/ops-meta/filmtower/COMPOSE# cat /usr/local/bin/docker-compose #!/bin/sh
Run docker-compose in a container
This script will attempt to mirror the host paths by using volumes for the
following paths:
* $(pwd)
* $(dirname $COMPOSE_FILE) if it’s set
* $HOME if it’s set
You can add additional volumes (or any docker run options) using
the $COMPOSE_OPTIONS environment variable.
set -e
VERSION=“1.13.0”
IMAGE=“docker/compose:$VERSION”
Setup options for connecting to docker host
if [ -z “$DOCKERHOST” ]; then
DOCKERHOST=“/var/run/docker.sock”
fi
if [ -S “$DOCKERHOST” ]; then
DOCKERADDR=“-v $DOCKERHOST:$DOCKERHOST -e DOCKERHOST”
else
DOCKERADDR=“-e DOCKERHOST -e DOCKERTLSVERIFY -e DOCKERCERT_PATH”
fi
Setup volume mounts for compose config and context
if [ “$(pwd)” != ’/’ ]; then
VOLUMES=“-v $(pwd):$(pwd)”
fi
if [ -n “$COMPOSEFILE” ]; then
composedir=$(realpath $(dirname $COMPOSE_FILE))
fi
TODO: also check –file argument
if [ -n “$composedir” ]; then
VOLUMES=“$VOLUMES -v $composedir:$compose_dir”
fi
if [ -n “$HOME” ]; then
VOLUMES=“$VOLUMES -v $HOME:$HOME -v $HOME:/root” # mount $HOME in /root to share docker.config
fi
Only allocate tty if we detect one
if [ -t 1 ]; then
DOCKERRUNOPTIONS=“-t”
fi
if [ -t 0 ]; then
DOCKERRUNOPTIONS=“$DOCKERRUNOPTIONS -i”
fi
exec docker run –rm $DOCKERRUNOPTIONS $DOCKERADDR $COMPOSEOPTIONS $VOLUMES -w “$(pwd)” $IMAGE “$@”
root@towergame:~/ops-meta/filmtower/COMPOSE#
this is no coincidence: I don’t see where COMPOSE_FILE is passed; not to mention it fails when it contains multiple files with separator and paths:
root@towergame:~/ops-meta/filmtower/COMPOSE# COMPOSE_FILE=“./docker-compose.yaml:./nginx.yaml” docker-compose –verbose up -d
docker: Error response from daemon: invalid bind mount spec “/root/ops-meta/filmtower/COMPOSE/docker-compose.yaml:.:/root/ops-meta/filmtower/COMPOSE/docker-compose.yaml:.”: invalid volume specification: ’/root/ops-meta/filmtower/COMPOSE/docker-compose.yaml:.:/root/ops-meta/filmtower/COMPOSE/docker-compose.yaml:.’.
See ‘docker run –help’.

Question: Do you plan to fix this and make docker-compose honour COMPOSE_FILE as in docker-compose docs?
