To Install Docker On Oracle Linux 9.4
Introduction
Docker is a software platform that enables users to efficiently build, test, and deploy applications. It packages software into standardized units known as containers, which include all the necessary components for the software to operate, such as libraries, system tools, code, and runtime environments.
Procedure
Step 1: Check the OS version by following command
[root@linuxhelp ~]# cat /etc/os-release
NAME="Oracle Linux Server"
VERSION="9.4"
ID="ol"
ID_LIKE="fedora"
VARIANT="Server"
VARIANT_ID="server"
VERSION_ID="9.4"
PLATFORM_ID="platform:el9"
PRETTY_NAME="Oracle Linux Server 9.4"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:oracle:linux:9:4:server"
HOME_URL="https://linux.oracle.com/"
BUG_REPORT_URL="https://github.com/oracle/oracle-linux"
ORACLE_BUGZILLA_PRODUCT="Oracle Linux 9"
ORACLE_BUGZILLA_PRODUCT_VERSION=9.4
ORACLE_SUPPORT_PRODUCT="Oracle Linux"
ORACLE_SUPPORT_PRODUCT_VERSION=9.4
Step 2: Run the following command to update your base system with the latest available packages.
[root@linuxhelp ~]# dnf update -y
Last metadata expiration check: 0:15:02 ago on Monday 12 August 2024 03:24:03 AM.
Dependencies resolved.
Nothing to do.
Complete!
Step 3: You can create it using the following command
[root@linuxhelp ~]# dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo
Adding repo from: https://download.docker.com/linux/centos/docker-ce.repo
Step 4: Run the following command to install Docker CE on your server
[root@linuxhelp ~]# dnf install docker-ce -y

Step 5: Start the Docker service
[root@linuxhelp ~]# systemctl start docker
Step 6: Enable to start at system reboot
[root@linuxhelp ~]# systemctl enable docker
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.
Step 7: verify the running status of the Docker service using the following command
[root@linuxhelp ~]# systemctl status docker

Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker ID:

Step 10: To verify the downloaded image
[root@linuxhelp ~]# docker images
