everyone!
i installed docker, docker-compose, then executed next commands:
`
sudo systemctl start docker.service
sudo systemctl status docker.service
sudo systemctl enable docker.service
sudo usermod -aG docker $USER
docker run hello-world`
OS: Manjaro, Archlinux
error: Server:
ERROR: Cannot connect to the Docker daemon at unix:. Is the docker daemon running?
ALREADY TRY A LOT!! Daemon won't start!
Try export DOCKER_HOST=unix:///var/run/docker.sock, then run docker run hello-world again.
I'm trying to kill my docker containers with the command:
$ docker container kill $(docker ps -q)
however, the containers aren't responding.
I'm able to log into them with:
$ docker exec -it container_id bash
but any commands within the terminal hangs.
Whats interesting is somehow the process also doesn't seem to exist. I get the list of running containers with the process ids as so:
$ for i in $(docker container ls --format "{{.ID}}"); do docker inspect -f '{{.State.Pid}} {{.Name}}' $i; done
12821 /brave_carson
12661 /trusting_hoover0
12617 /peaceful_franklin
12534 /frosty_volhard
12702 /zealous_sammet
12678 /flamboyant_jang
12690 /dreamy_driscoll
When I try to kill it with kill -9 pid I get the error:
$ kill -9 12821
-bash: kill: (12821) - No such process
This is very unusual. How do I resolve this? I'd prefer not to restart docker unless it is the last and only option.
If you kill the container, you cannot exec into it. The container must be running for exec to work (you should get an error message from this).
When the container is not running, there should be no process. However the container definition in docker, including logs, and changes to the container filesystem, will remain until you remove it with docker container rm (same as docker rm), e.g.:
docker container rm brave_carson
As a side note you can use docker run ... --rm ... to automatically remove containers after stop
When I tried to run ./byfn up in fabric-samples/first-network, I am getting the following error.
Error response from daemon: Could not kill running container
facc0618bbbe6741acf58167842b4a44f4749b69d9428936768959715c84c0fe,

container_linux.go:392: signaling init process caused "permission

I tried to reinstall docker, reload docker images, reload fabric-samples, checked at path but did not work out, can anyone light upon what causes to get this error, thanks.
Here is what worked for me. But it has to be repeated everytime. Therefore, its not a good solution:
sudo killall containerd-shim
If its still not working then delete everything and try again
sudo docker rm -vf $(sudo docker ps -a -q)
Try and if it stills complains then try:
sudo docker system prune -a
sudo docker rmi -f $(sudo docker images -q)
And if its still not working then delete the volumes as well
I am unable to remove the dead container, it appears again after i restart the Docker service.
docker ps -a
CONTAINER ID STATUS
11667ef16239 Dead
Then
docker rm -f 11667ef16239
Then, when I ran the docker ps -a, no docker containers showing.
docker ps -a
CONTAINER ID STATUS
However, when I restart the docker service:
service docker restart
And run the docker ps -a again:
docker ps -a
CONTAINER ID STATUS
11667ef16239 Dead
You can also remove dead containers with this command
docker rm $(docker ps --all -q -f status=dead)
But, I'm really not sure why & how the dead containers are created. This error seems related https://github.com/typesafehub/mesos-spark-integration-tests/issues/34 whenever i get dead containers
[Update]
With Docker 1.13 update, we can easily remove both unwanted containers, dangling images
$ docker system df #will show used space, similar to the unix tool df
$ docker system prune # will remove all unused data.
Most likely, an error occurred when the daemon attempted to cleanup the container, and he is now stuck in this "zombie" state.
I'm afraid your only option here is to manually clean it up:
$ sudo rm -rf /var/lib/docker/<storage_driver>/11667ef16239.../
Where <storage_driver> is the name of your driver (aufs, overlay, btrfs, or devicemapper).
Actually things changed slightly these days in order to get rid of those dead containers you may try to unmount those blocked filesystems to release them
So if you get message like this
Error response from daemon: Cannot destroy container elated_wozniak: Driver devicemapper failed to remove root filesystem 656cfd09aee399c8ae8c8d3e735fe48d70be6672773616e15579c8de18e2a3b3: Device is Busy
just run this
umount /var/lib/docker/devicemapper/mnt/656cfd09aee399c8ae8c8d3e735fe48d70be6672773616e15579c8de18e2a3b3
and you can normally remove container after that
I had the following error when removing a dead container (docker 17.06.1-ce on CentOS 7):
Error response from daemon: driver "overlay" failed to remove root filesystem for <some-id>:
remove /var/lib/docker/overlay/<some-id>/merged: device or resource busy
Here is how I fixed it:
1. Check which other processes are also using docker resources
$ grep docker /proc/*/mountinfo
which outputs something like this, where the number after /proc/ is the pid:
/proc/10001/mountinfo:179...
/proc/10002/mountinfo:149...
/proc/12345/mountinfo:159 149 0:36 / /var/lib/docker/overlay/...
2. Check the process name of the above pid
$ ps -p 10001 -o comm=
dockerd
$ ps -p 10002 -o comm=
docker-containe
$ ps -p 12345 -o comm=
nginx <<<-- This is suspicious!!!
So, nginx with pid 12345 seems to also be using /var/lib/docker/overlay/..., which is why we cannot remove the related container and get the device or resource busy error. (See here for a discussion on how nginx shares the same mount namespace with docker containers thus prevents its deletion.)
3. Stop nginx and then I can remove the container successfully.
$ sudo service nginx stop
$ docker rm <container-id>
I got the same issue and both answers did not help.
What helped for me is just creating the directories that are missing and them remove them:
mkdir /var/lib/docker/devicemapper/mnt/656cfd09aee399c8ae8c8d3e735fe48d70be6672773616e15579c8de18e2a3b3
mkdir /var/lib/docker/devicemapper/mnt/656cfd09aee399c8ae8c8d3e735fe48d70be6672773616e15579c8de18e2a3b3-init
docker rm 656cfd09aee399c8ae8c8d3e735fe48d70be6672773616e15579c8de18e2a3b3
Removing container by force worked for me.
docker rm -f <id_of_the_dead_container>
Notes:
Be aware that this command might throw this error
Error response from daemon: Driver devicemapper failed to remove root filesystem <id_of_the_dead_container>: Device is Busy
The mount of your's dead container device mapper should be removed despite this message. That is, you will no longer access this path:
/var/lib/docker/devicemapper/mnt/<id_of_the_dead_container>
Tried all of the above (short of reboot/ restart docker).
So here is the error om docker rm:
$ docker rm 08d51aad0e74
Error response from daemon: driver "devicemapper" failed to remove root filesystem for 08d51aad0e74060f54bba36268386fe991eff74570e7ee29b7c4d74047d809aa: remove /var/lib/docker/devicemapper/mnt/670cdbd30a3627ae4801044d32a423284b540c5057002dd010186c69b6cc7eea: device or resource busy
Then I did a the following:
$ grep docker /proc/*/mountinfo | grep 958722d105f8586978361409c9d70aff17c0af3a1970cb3c2fb7908fe5a310ac

This got be the PID of the offending process keeping it busy - 20416 (the item after /proc/
So I did a ps -p and to my surprise find:
[devops#dp01app5030 SeGrid]$ ps -p 20416
PID TTY TIME CMD
20416 ? 00:00:19 ntpd
A true WTF moment. So I pair problem solved with Google and found this:
Then found this https://github.com/docker/for-linux/issues/124
Turns out I had to restart ntp daemon and that fixed the issue!!!
For Deleting all dead container
docker rm -f $(docker ps --all -q -f status=dead)
For deleting all exited container docker rm -f $(docker ps --all -q -f status=exited)
As I have -f is necessary
Try running the following commands. It always works for me.
# docker volume rm $(docker volume ls -qf dangling=true)
# docker rm $(docker ps -q -f 'status=exited')
After execution of the above commands, restart docker by,
# service docker restart
grep 656cfd09aee399c8ae8c8d3e735fe48d70be6672773616e15579c8de18e2a3b3 /proc/*/mountinfo
then find the pid of 656cfd09aee399c8ae8c8d3e735fe48d70be6672773616e15579c8de18e2a3b3and and kill it
I have tried the suggestions above but didn't work.
Then
I try : docker system prune -a, it didn't work the first time
I reboot the system
I try again docker system prune -a. This time it works. It will send a warning message and in the end ask "Are you sure you want to continue? y/n? . Ans:y . It will time a time and in the end the dead containers are gone.
Verify with docker ps -a
IMPORTANT - this is the nuclear option as it destroys all containers + images
for Windows:
del D:\ProgramData\docker\containers\{CONTAINER ID}
del D:\ProgramData\docker\windowsfilter\{CONTAINER ID}
Then restart the Docker Desktop
Try kill it and then remove >:) i.e.
docker kill $(docker ps -q)
Try, It worked for me:
$ docker ps -a

Try this it worked for me:
docker rm -f <container_name>
eg. docker rm -f 11667ef16239
There are a lot of answers in here but none of them involved the (quick) solution that worked for me.
I'm using Docker version 1.12.3, build 6b644ec.
I simply ran docker rmi <image-name> for the image from whence the dead container came. A docker ps -a then showed the dead container missing completely.
Then, of course, I just re-pulled the image and ran the container again.
I have no idea how it found itself in this state but so it is...
In my case, I had to remove it with
rm -r /var/lib/docker/containers/<container-id>/
and it worked. Maybe that's how you solve it in docker version ~19. My docker version was 19.03.12,
For future users I wanna share my experience: (2022)
To see all containers I ran
docker container ls -a
then to kill containers I ran:
docker rm -f YOUR_CONTAINER_ID
for example:
docker rm -f d389s8dffe
Running on Centos7 & Docker 1.8.2, I was unable to use Zgr3doo's solution to umount by devicemapper ( I think the response I got was that the volume wasn't mounted/found. )
I think I also had a similar thing happen with sk8terboi87 ツ 's answer: I believe the message was that the volumes couldn't be unmounted, and it listed the specific volumes that it tried to umount in order to delete the dead containers.
What did work for me was stopping docker first, and then deleting the directories manually. I was able to determine which ones they were by the error output of previous command to delete all the dead containers.
Apologies for the vague descriptions above. I found this SO question days after I handled the dead containers. .. However, I noticed a similar pattern today:
$ sudo docker stop fervent_fermi; sudo docker rm fervent_fermi fervent_fermi
Error response from daemon: Cannot destroy container fervent_fermi: Driver devicemapper failed to remove root filesystem a11bae452da3dd776354aae311da5be5ff70ac9ebf33d33b66a24c62c3ec7f35: Device is Busy
Error: failed to remove containers: [fervent_fermi]
$ sudo systemctl docker stop

$
I did notice, when using this approach that docker re-created the images with different names:
a11bae452da3 trend_av_docker "bash" 2 weeks ago Dead compassionate_ardinghelli
This may have been due to the container being issued with restart=always, however, the container ID matches the ID of the container that previously used the volume that I force-deleted. There were no difficulties deleting this new container:
$ sudo docker rm -v compassionate_ardinghelli
compassionate_ardinghelli
Try this it worked for me on centos
1) docker container ls -a
gives you a list of containers check status which you want to get rid of
2) docker container rm -f 97af2da41b2b
not a big fan force flag but does the work
to check it worked just fire the command again or list it.
3) continue till we clear all dead containers
The best way to get rid of dead container processes is to restart your docker service.
I was unable to remove a container as it was stuck in restarting status, I just restarted the docker service and it worked for me.
I restarted the Docker Agent on Windows bottom right corner, docker iCon, Restart Docker. Then I ran docker ps -a and saw the container still sitting there.
I then ran docker rm -f container id and that worked for me.
If you are a Mac/Windows user and have Docker Desktop, you can just simply restart your Docker Desktop and in the UI you can simply remove the container without any complications.
In my case there was no actually mounted points inside docker container. Error raised after some ifup/down game inside privileged ct. The usual way of removing container didn’t work too uprising the similar error:
user#server:~$ docker rm -f tklc.dead
