Docker Part 1 – Install Docker CE and Docker Compose in Oracle Linux Server 8.6 – OCI-IAAS

Posted by Sriram Sanka on September 29, 2022

In this Post, lets see how to Install Docker CE . I am using Oracle Linux Server 8.6 (Free Instance Offered by Oracle Cloud) .

Docker lets you build, test, and deploy applications quickly, Docker is a software platform that allows you to build, test, and deploy applications quickly. Docker packages software into standardized units called containers that have everything the software needs to run including libraries, system tools, code, and runtime. Using Docker, you can quickly deploy and scale applications into any environment and know your code will run.

Docker Compose is a tool that was developed to help define and share multi-container applications. With Compose, we can create a YAML file to define the services and with a single command, can spin everything up or tear it all down.

The big advantage of using Compose is you can define your application stack in a file, keep it at the root of your project repo (it’s now version controlled), and easily enable someone else to contribute to your project. Someone would only need to clone your repo and start the compose app

Note : If there is no repo available in your OS, try adding EPEL repo and Try again.

[root@certbot conf.d]# dnf config-manager --add-repo=
Adding repo from:

Once the Repo is Added, we are good to go …..

run this command “dnf install docker-ce docker-ce-cli”

[root@certbot conf.d]# dnf install docker-ce docker-ce-cli

Enable and Start the docker Service

[root@certbot conf.d]# systemctl enable docker
Created symlink /etc/systemd/system/ → /usr/lib/systemd/system/docker.service.
[root@certbot conf.d]# systemctl start docker

Command “Docker PS” shows the running dockers.

[root@certbot conf.d]# docker ps

Lets Install Docker Compose as follows

[root@certbot conf.d]# curl -L "$(uname -s)-$(uname -m)" -o docker-compose
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

100 11.2M  100 11.2M    0     0  44.9M      0 --:--:-- --:--:-- --:--:-- 44.9M
[root@certbot conf.d]# mv docker-compose /usr/local/bin && sudo chmod +x /usr/local/bin/docker-compose
[root@certbot conf.d]# docker-compose version
docker-compose version 1.23.2, build 1110ad01
docker-py version: 3.6.0
CPython version: 3.6.7
OpenSSL version: OpenSSL 1.1.0f  25 May 2017
[root@certbot conf.d]#
Add user to docker group (if not already added)
sudo usermod -aG docker $USER
2. create a symbolic link to /usr/bin using the following command
$ sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
3. Restart docker service
$ sudo service docker restart
