Docker is the latest OS-level virtualization system. Docker is a very easy tool designed to make applications using containers. So now I want to share how to install docker ce (Community Edition) on you centos 7 server.

★ How To Install Grafana Server On Ubuntu 16.04 Server

My Centos 7 server details

OS Type : Centos 7
DISK : 50GB
RAM : 2GB
vCPU : 2

Step #01 : Check your server like os version, disk space and memory using below command.

For server os version check.

[root@Docker-Server ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)

Disk space check using below command.

[root@Docker-Server ~]# df -h
Filesystem               Size  Used Avail Use% Mounted on
/dev/mapper/centos-root   47G  981M   47G   3% /
devtmpfs                 482M     0  482M   0% /dev
tmpfs                    494M     0  494M   0% /dev/shm
tmpfs                    494M  6.8M  487M   2% /run
tmpfs                    494M     0  494M   0% /sys/fs/cgroup
/dev/xvda1              1014M  130M  885M  13% /boot
tmpfs                     99M     0   99M   0% /run/user/0

Memory check using this command.

[root@Docker-Server ~]# free -h
              total        used        free      shared  buff/cache   available
Mem:           986M        104M        757M        6.7M        123M        733M
Swap:          2.0G          0B        2.0G

Step #02: Now update & upgrade your centos 7 server.

[root@Docker-Server ~]# yum check-update
[root@Docker-Server ~]# yum update -y
[root@Docker-Server ~]# yum install epel-release -y
[root@Docker-Server ~]# reboot

Step #03: Install docker ce using below command for centos 7 server.

[root@Docker-Server ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
[root@Docker-Server ~]# yum-config-manager  --add-repo https://download.docker.com/linux/centos/docker-ce.repo
[root@Docker-Server ~]# yum install docker-ce docker-ce-cli containerd.io -y

Show docker-ce list using this command.

[root@Docker-Server ~]# yum list docker-ce --showduplicates | sort -r
