Solve the problem of running hello-world after docker installation

Installed Docker V1.13.1 on centos7.3 using yum

But when running: docker run hello-world, an error is reported:

# docker run docker.io/hello-world container_linux.go:247: starting container process caused "process_linux.go:258: applying cgroup configuration for process caused \"Cannot set property TasksAccounting, or unknown property.\"" /usr/bin/docker-current: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "process_linux.go:258: applying cgroup configuration for process caused \"Cannot set property TasksAccounting, or unknown property.\"".

solve:

The main reason is the compatibility issue of the centos system version. If the system is updated and upgraded, the problem can be solved.

yum update

Before update:

After update:

At this time, restart docker and run hello-world:

Additional knowledge: Deleting the none image

Delete the none image

// Stop all containers docker ps -a | grep "Exited" | awk '{print $1 }'|xargs docker stop
// Delete all stopped containers docker ps -a | grep "Exited" | awk '{print $1 }'|xargs docker rm
// Delete all images with tag none docker images|grep none|awk '{print $3 }'|xargs docker rmi
You can edit ~/.zshrc (or ~/.bashrc) to specify the command alias alias dnone="docker images|grep none|awk '{print $3}'|xargs docker rmi"
source ~/.zshrc
 ####################Official deletion command################

The reasons for the generation of the none image are:

how come

Combined with the first picture, let's sort out how dangling images are generated:

The image ID generated when the image is built for the first time is 079dbd67f9f4, and this image will be labeled bolingcavalry/eureka-server:0.0.1-SNAPSHOT by the build tool;

The image ID generated when the image is built for the second time is e40a97f764ef. This image will be labeled bolingcavalry/eureka-server:0.0.1-SNAPSHOT by the build tool.

Docker will remove the tag of 079dbd67f9f4, and 079dbd67f9f4 will become a dangling image, which will be displayed as <none>:<none> in the image list.

The official command provided is as follows to delete it. Note: If the none image is in use, it will not be deleted:

docker image prune
