The automated build docker Mediawiki system (CMS) image “linuxconfig/mediawiki” can be used to instantly deploy Mediawiki on your docker hosts.
The Mediawiki runs on Debian GNU/Linux system featuring Apache web server, MariaDB ( MySQL ), database and PHP5. A new docker container based on “linuxconfig/mediawiki” will expose port 80 which can be linked to the docker host port for an immediate Mediawiki web configuration/installation access.
The following linux commands can be used to remove all Docker images stored in your local repository. Be aware that you would not be able to undo any of the removed docker images. First, list all your docker images to make sure that there is nothing you want to remove:
# docker images
Using the following linux command you can obtain image IDs of all your docker images:
# docker images -q
To remove a single docker image simply run docker rmi followed by the image ID. For example:
# docker rmi 9fa0e1f381ad
Kimai is a free open source timetracker. It tracks the time you spend with various pre-set projects and prints out a summary of your activities on demand. The automated docker Kimai time tracker image “linuxconfig/kimai” can be used to instantly deploy the Kimai time tracker on your docker hosts.
The Kimai runs on Debian GNU/Linux system featuring Apache web server, MariaDB ( MySQL ), database and PHP5. After creating a docker container based on “linuxconfig/kimai” docker image, a port 80 will be exposed which can be access on the docker host for an immediate Kimai web configuration/installation as well as later access.
Configured MySQL users:passwords:
Configured MySQL databases:
Exposed ports:
The below command can be used to download and create a new docker container called kimai and link your docker host system’s port 80 with container’s exposed port 80.
# docker run -d --name=kimai -p 80:80 linuxconfig/kimai
Docker is a tool that is used to run software in a container. It’s a great way for developers and users to worry less about compatibility with an operating system and dependencies because the contained software should run identically on any system.
Docker is available for download and installation on Manjaro as well as most other distributions of Linux. After Docker is installed, you can use it to install software packages much the same way you would use your distro’s package manager to download an app. The difference of using Docker is that everything is more automated, with compatability and dependencies no longer being potential issues.
In this guide, we’ll show you how to install Docker on Manjaro Linux and get started with installing containerized software.
In this tutorial you will learn:
Docker is a combination of platform as a service products that use virtualization to provide software in packages called containers which can communicate with each other through well-defined channels. This tutorial focuses on Installing the latest Docker release on Ubuntu 20.04 LTS Focal Fossa.
In this tutorial you will learn:
Docker skills are high in demand mainly because, thanks to the Docker we can automate the deployment of applications inside so-called containers, creating tailored environments that can be easily replicated anywhere the Docker technology is supported. In this tutorial we will see how to create a Docker image from scratch, using a Dockerfile. We will learn the most important instructions we can use to customize our image, how to build the image, and how to run containers based on it.
In this tutorial you will learn:
This tutorial will provide you with simple to follow steps on how to install Docker on Fedora 31 Linux.
In this tutorial you will learn:
Install the latest Docker release on Ubuntu 18.04
Ubuntu 18.04 Bionic Beaver
A working install of Ubuntu 18.04 with root privileges
sudo commandDocker has revolutionized how web applications are hosted and servers are run. Docker containers allow server administrators to compartmentalize their applications like virtual machines, but containers are much lighter weight, are easier to manager, and add less overhead.
Installing Docker on Ubuntu is very simple. Because Ubuntu is a popular choice for the cloud, the entire process has been streamlined to a science.
Following this tutorial you will be able to create a LAMP environment using the Docker technology.
sudo command
Docker is an open source project aimed at providing software inside containers. You can think of a container as a sort of “package”, an isolated environment which shares the kernel with the host machine and contains everything the application needs. All containers are built using images (the central images repository for them being Dockerhub).
In this tutorial, we will see how to create a LAMP stack based on dockerized components: following the “one service per container” philosophy, we will assemble the environment using docker-compose, a tool to orchestrate container compositions.
The objective is to install Kubernetes on Ubuntu 18.04 Bionic Beaver Linux
Privileged access to your Ubuntu System as root or via sudo command is required.
In this guide we will be configuring the simplest possible Kubernetes cluster consisting of two nodes. The first node with hostname kubernetes-master will act as the master node.
The second node with hostname kubernetes-master also running Ubuntu 18.04 will be a slave node simply joining the Kuberneets cluster. Once we get the Kubernetes cluster up and running as a proof of concept we will deploy a Nginx server container.
The latest release of the RHEL 8 / CentOS 8. Red Hat has built its own tools, buildah and podman, which aim to be compatible with existing docker images and work without relying on a daemon, allowing the creation of containers as normal users, without the need of special permissions (with some limitations: e.g. at the moment of writing, it’s still not possible to map host ports to the container without privileges).
Some specific tools, however, are still missing: an equivalent of docker-compose, for example does not exists yet. In this tutorial we will see how to install and run the original Docker CE on Rhel8 by using the official Docker repository for CentOS7.
In this tutorial you will learn:
Even if Red Hat has developed podman and buildah, its own tools to work with containers, which come with some important advantages like a daemonless architecture, you may want to continue using the original Docker software on Fedora. In this tutorial we will explore the options we have on the latest release of the distribution to do so, and will see how to apply the needed fixes for Docker to work correctly.
