Check if docker images exist before real pulling
docker image list and tmp file read/write is much quicker then docker pull:
$ time sudo docker pull docker.io/kolla/centos-binary-ceph-mon:2.0.2 > /dev/null
real 0m3.418s
user 0m0.043s
sys 0m0.031s
$ cat pull_test.sh
sudo docker images | grep -v TAG | awk '{print $1,$2}' | while read -r image tag; do
echo ${image}:${tag} >> /tmp/imags.$$
done
echo docker.io/kolla/centos-binary-ceph-mon:2.0.2 | while read line; do
grep "$line" /tmp/imags.$$ > /dev/null 2>&1 && continue || true
echo Pulling container $line
sudo docker pull $line > /dev/null
done
$ time ./pull_test.sh
real 0m0.096s
user 0m0.070s
sys 0m0.044s
