I have Docker set up, including rootless mode, on a CentOS 8 Digital Ocean droplet. I am very new to this subject matter and am following along with Docker in a Month of Lunches and am now at the point where the reader is instructed to type in:
docker container run --interactive --tty diamol/base
Then the reader is instructed to open up another terminal, which I did, and type in:
docker container top [container id]
The command spits out the following:
Error response from daemon: runc did not terminate successfully: container_linux.go:187: getting all container pids from cgroups caused: lstat : no such file or directory
: unknown
Because I am a Docker neophyte, my ability to assist anyone reading to diagnose the problem is limited beyond providing what is typically asked for; however, I think it’s worth noting that the same thing happened when I tried the alpine:latest
image, meaning it’s not specific to the book image. It also seems worth pointing out that the same thing does not happen when I repeat the same procedure above but with sudo
.
Now, for the rest, as stated, I am using CentOS 8 on Digital Ocean. I used the get.docker.com
script and followed the instructions for rootless mode (with the minor and most likely unimportant deviation that I tailored the instructions to fish rather than bash; $DOCKER_HOST
has still been exported properly).
Specifically, here is the content of /etc/redhat-release
:
CentOS Linux release 8.4.2105
Here’s the output of uname -a
:
Linux metalicus 4.18.0-305.7.1.el8_4.x86_64 #1 SMP Tue Jun 29 21:55:12 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
And last but not least here’s the output of docker version

I’d be perfectly happy to attempt to supply whatever other details are needed to resolve the problem.
