Docker is a set of systems that use virtualization to deliver software in packages, which are called containers. The containers are isolated from the operating system and other containers, they have unique libraries, as well as packages and configuration files. In addition, they can run different operating systems and have a lower resource cost than traditional virtualization.
We provide the docker-ce, an edition of Docker that is free software, updated by the community. However, the package is officially not available for the Power architecture (ppc64 / ppc64le). Thus, the laboratory makes the latest versions available for installation from the package managers: Advanced Packaging Tool (APT) and Red Hat Package Manager (RPM).
This tutorial shows the step-by-step installation of Docker using the “.deb/.rpm” package. If you want to install using a package manager, read Installing Docker from the OpenPower Lab Repository.
Requirements
First of all, you need to install the Docker requirements. You can perform this operation using one of the commands below:
To Ubuntu/Debian:
sudo apt update
sudo apt install -y wget libseccomp2 libc6 libdevmapper1.02.1 libsystemd0 apparmor ca-certificates git libltdl7 pigz procps xz-utils runc
To RHEL/CentOS/Fedora:
sudo yum update
sudo yum install -y wget libseccomp glibc-utils device-mapper-libs systemd-libs ca-certificates git libtool-ltdl pigz procps xz runc
Install Docker
To install Docker-ce, it is necessary to download and install the packages: containerd, docker-ce, docker-ce-cli and docker-ce-rootless-extras. All these packages are available for download through our FTP, use one of the commands below to perform this operation:
Containerd was used in version 1.5.7 and Docker in 20.10.6. Change package versions! For the latest versions, access Oplab FTP.
To Ubuntu/Debian
wget https://oplab9.parqtec.unicamp.br/pub/repository/debian/ppc64el/containerd/containerd-1.5.7-ppc64le.deb https://oplab9.parqtec.unicamp.br/pub/ppc64el/docker/version-20.10.6/ubuntu-focal/docker-ce-rootless-extras_20.10.6~3-0~ubuntu-focal_ppc64el.deb https://oplab9.parqtec.unicamp.br/pub/ppc64el/docker/version-20.10.6/ubuntu-focal/docker-ce-cli_20.10.6~3-0~ubuntu-focal_ppc64el.deb https://oplab9.parqtec.unicamp.br/pub/ppc64el/docker/version-20.10.6/ubuntu-focal/docker-ce_20.10.6~3-0~ubuntu-focal_ppc64el.deb
To install on Ubuntu, use the dpkg:
sudo dpkg -i containerd-1.5.7-ppc64le.deb docker-ce-rootless-extras_20.10.6~3-0~ubuntu-focal_ppc64el.deb docker-ce-cli_20.10.6~3-0~ubuntu-focal_ppc64el.deb docker-ce_20.10.6~3-0~ubuntu-focal_ppc64el.deb
To RHEL/CentOS/Fedora:
wget https://oplab9.parqtec.unicamp.br/pub/repository/rpm/ppc64le/containerd/containerd-1.5.7-1.ppc64le.rpm https://oplab9.parqtec.unicamp.br/pub/ppc64el/docker/version-20.10.6/centos-8/docker-ce-rootless-extras-20.10.6-3.el8.ppc64le.rpm https://oplab9.parqtec.unicamp.br/pub/ppc64el/docker/version-20.10.6/centos-8/docker-ce-cli-20.10.6-3.el8.ppc64le.rpm https://oplab9.parqtec.unicamp.br/pub/ppc64el/docker/version-20.10.6/centos-8/docker-ce-20.10.6-3.el8.ppc64le.rpm
To install on CentOS 8, use the yum localinstall:
sudo yum localinstall containerd-1.5.7-1.ppc64le.rpm docker-ce-rootless-extras-20.10.6-3.el8.ppc64le.rpm docker-ce-cli-20.10.6-3.el8.ppc64le.rpm docker-ce-20.10.6-3.el8.ppc64le.rpm
Enable and verify Docker
Before using Docker, you need to enable it and start it. This process is also used to verify that the installation was successful.
sudo systemctl enable docker
sudo systemctl start docker
sudo systemctl status docker
Expected output:
ubuntu@docker-build:~$ sudo systemctl enable docker
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.
ubuntu@docker-build:~$ sudo systemctl start docker
ubuntu@docker-build:~$ sudo systemctl status docker
