Overview
Set up a Docker environment on Sakura VPS. Initial server settings, etc., are omitted.
Setup Procedure
All operations are assumed to be performed by a regular user with sudo privileges.
Docker has a free CE version and a commercial EE version, but we will use the CE version this time.
Set Up the Repository
Installation
sudo yum install -y yum-utils \
device-mapper-persistent-data \
lvm2
Set Up the Stable Repository
sudo yum-config-manager \
--add-repo \ https://download.docker.com/linux/centos/docker-ce.repo
Set Up the Edge and Test Repositories
sudo yum-config-manager --enable docker-ce-edge
sudo yum-config-manager --enable docker-ce-test
Since we only want to use stable, disable them with --disable.
sudo yum-config-manager --disable docker-ce-edge
sudo yum-config-manager --disable docker-ce-test
Install Docker CE
sudo yum install docker-ce
You can check the available versions for installation with the following command.
yum list docker-ce --showduplicates | sort -r
To install a specified version, specify the version as follows.
sudo yum install docker-ce-<VERSION STRING>
Start Docker
sudo systemctl start docker
Check if it's running.
sudo docker run hello-world
Uninstall Docker CE
sudo yum remove docker-ce
Docker images, volumes, containers, and configuration files are not automatically deleted, so manually delete the following directory.
sudo rm -rf /var/lib/docker
