Lab 001: Install Docker Package

Requirements​

Last week the Nautilus DevOps team met with the application development team and decided to containerize several of their applications. The DevOps team wants to do some testing per the following:

  • Install docker-ce and docker-compose packages on App Server 1.

  • Start docker service.

Note

This document preserves the original task text in Requirements and shows one direct implementation path for the package installation.

Prerequisites​

  • You can SSH to App Server 1 and switch to a privileged shell.
  • The host can reach the Docker package repositories and GitHub release download URL used in the steps.
  • yum-config-manager is available on the host so the Docker CE repository can be added before installation.

Steps​

Login to the App server and switch to root. For the server credentials, check out the Project Nautilus documentation.

sshpass -p  '***********' ssh -o StrictHostKeyChecking=no tony@172.16.238.10
sudo su -

Download the docker-compose binary. Make the binary executable. Check version.

curl -L "https://github.com/docker/compose/releases/download/1.28.6/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose  
chmod +x /usr/local/bin/docker-compose 
[root@stapp01 ~]# ls -la  /usr/local/bin/docker-compose
-rwxr-xr-x 1 root root 12212176 May 29 12:59 /usr/local/bin/docker-compose
[root@stapp01 ~]# docker-compose --version 
docker-compose version 1.28.6, build 5db8d86f

Next, download docker. Afterwards, verify that docker is successfully installed.

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo  
yum install -y docker-ce docker-ce-cli containerd.io
[root@stapp01 ~]# rpm -qa |grep docker 
docker-buildx-plugin-0.10.5-1.el7.x86_64
docker-ce-24.0.2-1.el7.x86_64
docker-compose-plugin-2.18.1-1.el7.x86_64
docker-ce-cli-24.0.2-1.el7.x86_64
docker-ce-rootless-extras-24.0.2-1.el7.x86_64

Enable and start the service.

systemctl enable docker  
systemctl start  docker
systemctl status  docker

Verify.

[root@stapp01 ~]# docker --version 
Docker version 24.0.2, build cb74dfc

[root@stapp01 ~]# docker-compose --version
docker-compose version 1.28.6, build 5db8d86f

Verification​

  • Confirm the Docker Engine packages are installed with rpm -qa | grep docker.
  • Confirm the Docker service is enabled and running with systemctl status docker.
  • Confirm the CLI tools are available with docker --version and docker-compose --version.
