Để đơn giản hơn trong quá trình lab hoặc dựng nhanh các môi trường cần thiết, hôm nay mình chia sẻ script cài đặt docker, docker-compose trên môi trường các hệ điều hành Ubuntu và CentOS.

• Ubuntu Server 18.04 64 bit.
• CentOS 7 Server 64 bit.

Các bước thực hiện như sau:

Bước 1: Update & tải các gói cần thiết.

Đối với Centos

 yum update -y && yum install -y wget

Đối với Ubuntu

apt update -y && apt install -y wget

Bước 2: Tạo script như sau

Tạo với tên là docer-install.sh

#!/bin/bash
if [ ! -z `sudo which apt | grep "/apt"` ]; then
sudo apt -y update
sudo apt -y install git wget
elif [ -z `sudo which yum | grep "/yum"` ]; then
yum update
yum install -y wget git
fi
is_ubuntu=`awk -F '=' '/PRETTY_NAME/ { print $2 }' /etc/os-release | egrep Ubuntu -i`
is_centos=`awk -F '=' '/PRETTY_NAME/ { print $2 }' /etc/os-release | egrep CentOS -i`
if [ ! -z "$is_ubuntu" ]; then
is_docker_exist=`dpkg -l | grep docker -i`
elif [ ! -z "$is_centos" ]; then
is_docker_exist=`rpm -qa | grep docker`
else
echo"Error: Current Linux release version is not supported, please use either centos or ubuntu. "
exit
fi
if [ ! -z "$is_docker_exist" ]; then
echo"Warning: docker already exists. "
fi
function ubuntu_install()
{

ubuntu_install
elif [ ! -z "$is_centos" ]; then
centos_install

docker_compose_install
docker-compose --version
echo "Docker-compose has been installed successfully."

Bước 3: Chạy lệnh sau để cài đặt

Cấp quyền thực thi và chạy:

chmod +x docker-install.sh
./docker-install.sh

Sau khi thực hiện xong các bạn kiểm tra status docker

systemctl status docker
sudo docker run hello-world
