Docker auf RHEL / CentOS 7
In this 3-article series, we will discuss about Docker, is an open-source lightweight virtualization tool which runs at top of Operating System level, allowing users to create, run and deploy applications, encapsulated into small containers.
Installation von Docker und Docker-Compose
Step 1 - Install deps, add docker Repo and setup Docker:
# yum install -y yum-utils device-mapper-persistent-data lvm2 # yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo # yum update # yum install docker-ce docker-ce-cli containerd.io # systemctl start docker && systemctl enable docker
Step 2 - Install docker-compose binary:
# newest_version="$(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep -Po '"tag_name": "\K.*?(?=")')"
# curl -L "https://github.com/docker/compose/releases/download/${newest_version}/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
# chmod +x /usr/local/bin/docker-compose
# curl -L https://raw.githubusercontent.com/docker/compose/$(docker-compose version --short)/contrib/completion/bash/docker-compose -o /etc/bash_completion.d/docker-compose
# docker-compose version
Installation Docker Environment
Step 1 - Update the System and install Docker:
# apt-get update
Docker Grundlagen
This type of Linux containers are proven to be fast, portable and secure. The processes that run in a Docker container are always isolated from the main host, preventing outside tampering.
