Bamboo "cannot connect to Docker daemon"

My Bamboo build plan (running on an linux64 agent) has a stage to do a source code checkout from my GitHub repo, and then a stage to build an image with that Dockerfile, which looks like this:

set -o xtrace
set -o errexit
${bamboo_DOCKER_SIGNATURE} build ${bamboo_DOCKER_BUILD_EXTRAS} -t myname:${bamboo_buildNumber} -f Dockerfile .

The next stage I want is a script that pushes this image to my Docker registry (on Quay.io). The script I have so far is below, but the build fails with the error "Cannot connect to the Docker daemon. Is the docker daemon running on this host?".

set -o xtrace
set -o errexit

# service docker start  # commented out b/c this did not solve the docker daemon issue

# This is where the build fails:
docker login -e="." -u=${bamboo.QUAY_ROBOT_name} -p=${bamboo.QUAY_ROBOT_token} quay.io

# Push the image to 'my_repo' in the Quay.io organization 'my_team', with tag 'bamboo_build'
docker push quay.io/my_team/my_repo:bamboo_build${bamboo_buildNumber}

FWIW the same login command works as expected from my local command line. How can I remedy this? Also, using Bamboo's built in Docker task does not work -- it's unable to login to the registry, but for some reason does not have the "docker daemon" issue. Thank you in advance for any help!

The trick was to use the Bamboo variable ${bamboo_DOCKER_SIGNATURE} instead of docker. This variable says to use a specific host--i.e., docker -H <host address>.
