Update Docker Version Centos

Now install the newer docker-ce version from the Docker repository and containerd manually, because due to some issues, Red Hat blocked the installation of containerd.io 1.2.0-3.el7, which is a dependency of docker-ce. Dnf Install Docker-ce Centos8; Install Docker Ce Centos 8 Download; Install Docker Ce On Centos 8. Example systemd enabled app container. In order to use the systemd enabled base container created above, you will need to create your Dockerfile similar to the one below. FROM local/c7-systemd RUN yum -y install httpd; yum clean all; systemctl enable httpd.service EXPOSE 80 CMD '/usr/sbin/init' Build this image: $ docker build -rm -t local.

About Docker

Upgrade packages through yum tool. Install Docker from yum repository. Check from the rpm database if docker is installed or not. Check the Docker version. In this article, I will take you through the steps to install docker on CentOS 7. Docker is an open source software platform to create, deploy. There are two ways to address this issue and install Docker on CentOS 8. Install Docker CE on CentOS 8 Option 1: Skip Packages with Broken Dependencies. An efficient solution is to allow your CentOS 8 system to install the version that meets the criteria best, using the -nobest command: sudo dnf install docker-ce -nobest.

'Docker containers wrap a piece of software in a complete filesystem that contains everything needed to run: code, runtime, system tools, system libraries – anything that can be installed on a server. This guarantees that the software will always run the same, regardless of its environment.' - docker.com/what-docker

Installation and configuration

CERN CentOS 7 provides two versions of docker:

  • docker - stable version 1.10 with backported patches.
  • docker-latest - latest version updated periodically - 1.13 (Apr 2017).

To install run on your system as root:

Note: While two above versions can be installed in parallel, only one can be usedon the system at any given time (different data storage paths, different system services started).

To configure and start docker system service run:and run docker using:

To configure and start docker-latest system service run:and in addition edit /etc/sysconfig/dockeradding a line:and run docker using:


CERN base images

We provide (and regularily update) prebuiltDocker images for: Scientific Linux CERN 5, Scientific Linux CERN 6 and CERN CentOS 7.

Please see: CERN Docker images for information.

Building layered image using CERN base image

Centos Update Docker Version

For full documentation about building images please refer to Docker documentation. Docker session below shows only how to build/push a simple layered image.
  • Pull base image from registry:
  • List images:
  • Create a Dockerfile in subdirectory: containing:
  • Start build:
  • List images:
  • Test your image:
  • Tag the image:
  • And push it to registry (note: the registry must be preconfigured in GitLab first):

Learning docker from scratch

  • Step 1: after the environment is installed, first change the yum source to alicloud version

1. Backup the current Yum source. If there is an accident, you can directly restore this version

2. Download WGet CentOS without WGet. Manual installation is required


3. Use WGet to download Alibaba cloud Yum source files

4. Clean up old bags

5. Set the downloaded Alibaba cloud repo file as the default source

6. Generate the yum source cache of alicloud and update the yum source

  • Step 2: after updating the yum source, install docker CE

0. Uninstall the old version of docker (do not operate this step if the new server is used)

1. Install some necessary system tools

2. Add software source information

3. Update the yum cache

4. View the current version of docker ce that can be installed

5. The latest version of docker CE is installed by default. You can also specify the version of docker by yourself
