Docker not running

Question

I am using Cloudera Vm and trying to work with docker. I have installed it, but maybe there is something wrong with the installation. I tried to uninstall it and install it again clearly, but still the same issue.

I followed the steps for installation here: https://docs.docker.com/engine/install/centos/#install-using-the-repository

And after the following command

sudo yum install docker-ce docker-ce-cli containerd.io

I got the following errors at the end. Could that be the reason of my issues and if yes how can I fix these? (I tried the suggestions at the end of the error message but they did not help)

Error: Package: containerd.io-1.2.13-3.2.el7.x86_64 (docker-ce-nightly)

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Below you can see some of the commands which I tried.

[cloudera@quickstart ~]$ sudo docker --version Docker version
19.03.13-beta2, build ff3fbc9d55

[cloudera@quickstart ~]$ docker image ls
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

[cloudera@quickstart ~]$ ls -l /var/run/docker.sock
ls: cannot access /var/run/docker.sock: No such file or directory

[cloudera@quickstart ~]$ sudo service docker start
docker: unrecognized service

[cloudera@quickstart ~]$ sudo service docker.io start
docker.io: unrecognized service

docker: 'ls' is not a docker command.
See 'docker --help'

[cloudera@quickstart ~]$ docker version

Can you maybe see the problem or give me a hint what command should I run for more information?

Do you follow the installation steps in the docker documentation? — Daniel Marques, Sep 15 '20 at 16:02
Definitely something went wrong in your docker installation. Please paste here the link from where you did follow the steps... Also during the installation do you notice something strange? — Daniel Marques, Sep 15 '20 at 16:14
Another thing is that I suggest you installing a stable version like `19.03.12` — Daniel Marques, Sep 15 '20 at 16:17
Sorry, I forgot to add this, thank you. I updated my question. — gigives, Sep 15 '20 at 17:06
I almost sure you enable the nightly or test repositories during the installation, this is generally a bad idea because these versions are with some bugs that they are fixing before the stable version being released. I think the best thing to do is uninstall then install the last stable docker release. Examplo: `sudo yum install docker-ce-19.03.12 docker-ce-cli-19.03.12 containerd.io` — Daniel Marques, Sep 15 '20 at 17:36
Is this CentOS 7 (not CentOS 8)? https://docs.docker.com/engine/install/centos/#os-requirements — BMitch, Sep 15 '20 at 18:52
@Howard_Roark I have CentOS release 6.10 (final). And I checked the websites with the tutorials how to install it on centos 6 and it isn't working.. it is giving me these errors again. — gigives, Sep 18 '20 at 13:45
@DanielMarques this command is also not working. I disabled the nightly and test repositories as well... — gigives, Sep 18 '20 at 13:47
I think Docker isn't supported on Centos6 based on what I read before I asked you that question — Howard_Roark, Sep 18 '20 at 13:58
It could be that. @Howard_Roark CentOS 6 will reach the end of life in November 2020. It's possible creating CentOS 6 VMs on Cloudera, but not install docker on it. I cannot think of another reason that explains the current behavior of docker within your VM. Isn't possible for you creating a CentOS 7 VM and install docker in it? — Daniel Marques, Sep 18 '20 at 15:52

Per my comment, I don't think Docker is supported on CentOS6. You can see that a previous poster ran into this as well. And you can see in the Prerequisites in the instructions that you are following that they say you need CentOS7.

To install Docker Engine, you need a maintained version of CentOS 7. Archived versions aren’t supported or tested.

Redhat provides a short explanation here of why Docker doesn't work well with RHEL6.

Many of the docker project's features are tied to capabilities in the RHEL 7 kernel as well as various infrastructure component updates like devicemapper for thin provisioning, direct LVM, sVirt and systemd
