pvcreate /dev/sdd

# create a volume group named 'docker' (replace /dev/sdd with your block device)
vgcreate docker /dev/sdd

# create a thin pool named 'thinpool'; in this example, the data LV is 95% of the 'docker' volume group size (leaving free space allows for auto expanding of either the data or metadata if space is runs low as a temporary stopgap)
lvcreate --wipesignatures y -n thinpool docker -l 95%VG
lvcreate --wipesignatures y -n thinpoolmeta docker -l 1%VG

# convert the pool to a thin-pool
lvconvert -y --zero n -c 512K --thinpool docker/thinpool --poolmetadata docker/thinpoolmeta

#  configure autoextension of thin pools via a lvm profile
vi /etc/lvm/profile/docker-thinpool.profile

# specify the value for 'thin_pool_autoextend_threshold' (where the number is the % of space used before lvm attempts to autoextend the available space; 100 = disabled)
example:
    thin_pool_autoextend_threshold = 80

# modify the autoextend percentage for when thin pool autoextension occurs (where the number is the % of space to increase the thin pool; 100 = disabled)
example:
    thin_pool_autoextend_percent = 20

example /etc/lvm/profile/docker-thinpool.profile:
activation {
    thin_pool_autoextend_threshold=80
    thin_pool_autoextend_percent=20
}

# apply the lvm profile
lvchange --metadataprofile docker-thinpool docker/thinpool

# verified the lv is monitored
lvs -o+seg_monitor

# configure docker daemon with specific devicemapper options
--storage-driver=devicemapper --storage-opt=dm.thinpooldev=/dev/mapper/docker-thinpool --storage-opt dm.use_deferred_removal=true
    also see `man docker daemon` for more detail on the devicemapper options used.

example daemon.json:
{
        "storage-driver": "devicemapper",
        "storage-opts": [
                "dm.thinpooldev=/dev/mapper/docker-thinpool",
                "dm.use_deferred_removal=true"
        ]
}

# if docker was previously started, clear your graph driver directory
rm -rf /var/lib/docker/*

# start docker
systemctl start docker

# make sure to monitor your thin pool and volume group free space!  it will auto-extend but the volume group can still fill up
# monitor logical volumes
lvs
lvs -a (to see the data and metadata sizes)

# monitor volume group free space
vgs

# logs can show the auto-extension of the thin pool when it hits the threshold
journalctl -fu dm-event.service
