I use ubuntu 16.04.
Suddenly (sorry), I can't run docker.
When I run command in the terminal I only have this (expected output was info about client and daemon versions):
$ sudo docker --version
Docker version 1.12.3, build 6b644ec
When I run commands line this
$ sudo docker ps
I have nothing for long time:
How can I overcome this problem?
$ sudo service docker status

When I get such output when I run:

This looks like a docker swarm certificate related issue as reported here
A solution to this problem will be released in version 1.13. For now you can try forcing recreating the swarm as explained here.

Could anyone tell me why docker service start failed after modifying daemon.json file? And how to specify cgroupdriver, default log-driver and default storage-driver in the right way?
Any suggestion will be greatly appreciated.
Thanks.
This error is pointing to an issue forcing docker to use overlay2 without the proper backing filesystem:
failed to start daemon: error initializing graphdriver: overlay2: the backing xfs filesystem is formatted without d_type
See docker's table for details on backing filesystem requirements for the different storage drivers: https://docs.docker.com/storage/storagedriver/#supported-backing-filesystems
The fix is to remove the storage driver settings, or fix the backing filesystem with the needed options to support overlay2:
{
"exec-opts": ["native.cgroupdriver=systemd"],
"log-driver": "json-file",
"log-opts": {
"max-size": "100m"
}
}
For details on changing the xfs options, that appears to require rebuilding the filesystem. See this answer for more details on the needed steps.
After I install the docker, I have set the selinux status to Permissive, still can not run docker.
In my /etc/selinux/config, I have edit the SELINUX=disabled.
and setenforce 0, check with:
# getenforce
Permissive
I use systemctl start docker, but failed, get bellow error:

My linux is CentOS 7.2
I find the solution.
in the /etc/sysconfig/docker:
OPTIONS='--selinux-enabled --log-driver=journald --signature-verification=false'
if [ -z "${DOCKER_CERT_PATH}" ]; then
DOCKER_CERT_PATH=/etc/docker
fi
set the -selinux-enabled to --selinux-enabled=false.

How to solve this issue?
I am running docker on a Redhat system with devicemapper and thinpool device just as recommended for production systems. Now when I want to reinstall docker I need two steps:
1) remove docker directory (in my case /area51/docker)
2) clear thinpool device
The docker documentation states that when using devicemapper with dm.metadev and dm.datadev options, the easiest way of cleaning devicemapper would be:
If setting up a new metadata pool it is required to be valid.
This can be achieved by zeroing the first 4k to indicate empty metadata, like this:
$ dd if=/dev/zero of=$metadata_dev bs=4096 count=1
Unfortunately, according to the documentation, the dm.metadatadev is deprecated, it says to use dm.thinpooldev instead.
My thinpool has been created along the lines of this docker instruction
So, my setup now looks like this:
cat /etc/docker/daemon.json
{
"storage-driver": "devicemapper",
"storage-opts": [
"dm.thinpooldev=/dev/mapper/thinpool_VG_38401-thinpool",
"dm.basesize=18G"
]
}
Under the devicemapper directory i see the following thinpool devices
ls -l /dev/mapper/thinpool_VG_38401-thinpool*
lrwxrwxrwx 1 root root 7 Dec 6 08:31 /dev/mapper/thinpool_VG_38401-thinpool -> ../dm-8
lrwxrwxrwx 1 root root 7 Dec 6 08:31 /dev/mapper/thinpool_VG_38401-thinpool_tdata -> ../dm-7
lrwxrwxrwx 1 root root 7 Dec 6 08:31 /dev/mapper/thinpool_VG_38401-thinpool_tmeta -> ../dm-6
So, after running docker successfully I tried to reinstall as described above and clear the thinpool by writing 4K zeroes into the tmeta device and restart docker:
dd if=/dev/zero of=/dev/mapper/thinpool_VG_38401-thinpool_tmeta bs=4096 count=1
systemctl start docker
And endet up with

So, obviously writing zeroes into the thinpool_meta device is not the right thing to do, it seems to destroy my thinpool device.
Anyone here that can tell me the right steps to clear the thin-pool device? Preferably the solution should not require a reboot.
