Docker not completely removed

Question

I have a problem while installing docker-ce

I trying to remove old docker by using command yum remove docker docker-common docker-selinux docker-engine. But I noticed that all docker command is still usable. For example, [root@caffeDNN ~]# docker version Client: Version: 1.13.1 API version: 1.26 Go version: go1.7.5 Git commit: 092cba3 Built: Wed Feb 8 08:47:51 2017 OS/Arch: linux/amd64 Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? [root@caffeDNN ~]# So, I trying to uninstall it again by using the same command but yum could not found any docker package anymore.

Is there any solution to remove docker completely by avoiding conflict with docker-ce?

Method I tried

Answer 1

Execute:

sudo yum remove docker \
              docker-client \
              docker-client-latest \
              docker-common \
              docker-latest \
              docker-latest-logrotate \
              docker-logrotate \
              docker-engine

And delete

• the directories /var/lib/docker, which contains your images, containers and volumes
• and /etc/docker, which contains docker configuration files.

But if you want to reinstall it anyway just continue.

It’s OK if yum reports that none of these packages are installed.

Answer 2

for newer versions you need to remove the cli as well

sudo yum remove -y docker-ce docker-ce-cli

that will do the trick
