Here are my simplest steps to install Docker and Docker Compose into Ubuntu 18.04 and 16.04.
For Ubuntu, usually following three commands will get you both docker and docker-compose installed.
apt-get update
apt-get install docker
apt-get install docker-compose
Install Docker and Compose into Ubuntu 18.04
Just one command:
snap install docker
root@ubuntu18-04-1:~# snap install docker docker 18.09.9 from Canonical✓ installed
It will also install docker-compose. If your Ubuntu 18.04 notifies you do not have snap, you can install it with following command:
apt install snap
root@ubuntu18-04-1:~# docker version Client: Version: 18.09.9 API version: 1.39 Go version: go1.13.4 Git commit: 1752eb3 Built: Sat Nov 16 01:05:26 2019 OS/Arch: linux/amd64 Experimental: false Server: Engine: Version: 18.09.9 API version: 1.39 (minimum version 1.12) Go version: go1.13.4 Git commit: 9552f2b Built: Sat Nov 16 01:07:48 2019 OS/Arch: linux/amd64 Experimental: false root@ubuntu18-04-1:~# docker-compose version docker-compose version 1.23.2, build unknown docker-py version: 3.7.3 CPython version: 2.7.12 OpenSSL version: OpenSSL 1.0.2g 1 Mar 2016 root@ubuntu18-04-1:~#
root@ubuntu18-04-1:~# docker run hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world 1b930d010525: Pull complete Digest: sha256:9572f7cdcee8591948c2963463447a53466950b3fc15a247fcad1917ca215a2f 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: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/get-started/ root@ubuntu18-04-1:~# root@ubuntu18-04-1:~# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE hello-world latest fce289e99eb9 13 months ago 1.84kB root@ubuntu18-04-1:~#
Or, just issue following three commands:
sudo -i yum -y update curl -sSL https://get.docker.com/ | shThen execute the following command to install Docker CE:
$ sudo yum install docker-ce –yInstall Docker and Compose into Ubuntu 16.04
For Ubuntu 16.04, you will need six commands to install Docker:sudo apt update sudo apt install apt-transport-https ca-certificates curl software-properties-common curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" sudo apt update sudo apt -y install docker-ce
For Docker-Compose, you will either using following command to take it longer :
apt install docker-compose
Or you can use following two commands to get it done faster:
curl -L "https://github.com/docker/compose/releases/download/1.19.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose
You can test your first example docker hello-world with following command:
docker run hello-world
This command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits.

For 18.04,
sudo apt-get update
sudo apt-get upgrade
sudo apt install docker.io
sudo apt install docker-ce
sudo systemctl start docker
sudo systemctl enable docker
sudo systemctl status docker
docker -v

Method 2:
Step 1 — Install Docker
Install needed packages:
$ sudo yum install -y yum-utils device-mapper-persistent-data lvm2
Configure the docker-ce repo:
$ sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
Install docker-ce:
$ sudo yum install docker-ce
Add your user to the docker group with the following command.
$ sudo usermod -aG docker $(whoami)
Set Docker to start automatically at boot time:
$ sudo systemctl enable docker.service
Finally, start the Docker service:
$ sudo systemctl start docker.service
Step 2 — Install Docker Compose
Install Extra Packages for Enterprise Linux
$ sudo yum install epel-release
Install python-pip
$ sudo yum install -y python-pip
Then install Docker Compose:
$ sudo pip install docker-compose
You will also need to upgrade your Python packages on CentOS 7 to get docker-compose to run successfully:
$ sudo yum upgrade python*
To verify a successful Docker Compose installation, run:
$ docker-compose versionInstall Docker and Compose into Oracle Linux 7.7
Docker and Git are required for the subsuquent labs. You will install the Docker engine, enable it to start on re-boot, grant docker privledges to theÂ
opc user and finally install Git.- TheÂ
sudo -s command brings you to theÂroot context, where you can run commands as a "super-user" and gain more administrative privileges. Once you have SSH'd into the compute instance and see something along the lines ofÂ[opc@dockertest ~]$, run the following commands:
sudo -s
yum install docker-engine
During theÂ
yum install docker-engine command press Y is asked if installation is ok. Then run these commands: usermod -aG docker opc
systemctl enable docker
systemctl start docker
- Run the following command to install git:
yum install git
TheÂ
su - opc command brings you to a new context identical to that of the original opc user context upon successfully SSH'ing into the compute instance. Run the following commands to verify good installations: su - opc
docker version
docker images
git --versionReferences
