Install docker on RedHatLinux 6.7

Question

I am following the documentation https://docs.docker.com/engine/installation/rhel/ to install docker on RHEL 6.7. When I run the command

sudo yum install docker-engine

I get the following error

Error: Package: docker-engine-1.9.1-1.el7.centos.x86_64 (dockerrepo)
           Requires: libsystemd-journal.so.0(LIBSYSTEMD_JOURNAL_196)(64bit)
Error: Package: docker-engine-1.9.1-1.el7.centos.x86_64 (dockerrepo)
           Requires: libsystemd-journal.so.0(LIBSYSTEMD_JOURNAL_195)(64bit)
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

As per the suggestion I tried to run the command

sudo yum install docker-engine --skip-broken

Here is the output

    Packages skipped because of dependency problems:
    audit-libs-python-2.3.7-5.el6.x86_64 from RHEL-67-x86_64

    setools-libs-python-3.3.7-4.el6.x86_64 from RHEL-67-x86_64

How can I fix above problems and install docker on RHEL 6.7 ?

Answer 1

RHEL 6 is no longer supported by Docker, the latest version you can install is Docker 1.7. The installation instructions can be found here

Answer 2

Below steps do work for Docker to be installed on OEL 6.10 with a user having super user privileges.

1. Create a user with SUDO Access as suggested in Red-Hat Docs ([Link][1] speaks well on this process). For instance I created an user as docker with group as docker.

   groupadd docker  
   useradd -m -g docker docker
   

2. Add docker repository for installing latest copy of Docker for RHEL/Centos 6

   yum update -y  
   yum install epel-release  
   vi /etc/yum.repos.d/docker.repo   
   

3. Add below contents to /etc/yum.repos.d/docker.repo

   [docker-repo]  
   name=Docker Repo  
   baseurl=https://yum.dockerproject.org/repo/main/centos/6/  
   enabled=1  
   gpgcheck=1  
   gpgkey=https://yum.dockerproject.org/gpg  
   

4. Switch to "docker" user and execute below commands:

   sudo yum install -y docker-engine

5. Post Installation start docker using below commands.

   sudo chkconfig docker on  
   
   sudo service docker start  
   Starting cgconfig service:                                 [  OK  ]  
   Starting docker:                                           [  OK  ]  
   
   sudo service docker status  
   docker (pid  26925) is running...  
   
   ps -ef | grep docker  
   root     25590 14123  0 Jul27 ?        00:00:00 sshd: docker [priv]  
   docker   25594 25590  0 Jul27 ?        00:00:00 sshd: docker@pts/1  
   docker   25595 25594  0 Jul27 pts/1    00:00:00 -bash  
   root     26925     1  2 00:00 pts/1    00:00:00 /usr/bin/docker -d  
   docker   27106 25595  0 00:00 pts/1    00:00:00 ps -ef  
   docker   27107 25595  0 00:00 pts/1    00:00:00 grep docker  
   
   docker ps -a  
   CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
