Ubuntu

So, we have installed the Ampache streaming server. Now, we will learn how to upload our audio/video content and create our first catalog.

Getting ready

You will need audio and video files to be uploaded on your server and enough space to save all this content. I will be using podcasts from Ubuntu podcasts in the MP3 format.

Upload all content to your Ampache server and note the directory path. I will be using the podcasts directory under home for my user.

Open the Ampache server homepage and log in with admin credentials.

This recipe covers the installation of the Ampache server. It is a simple PHP-based web application. Once installed and set up, you can use a web interface to play your audio/video files or use any of the various popular streaming clients to stream content over the intranet or even the Internet.

Getting ready

We will be using Ubuntu Server 16.04, but you can choose to have any version of Ubuntu.

Additionally, we will need the Samba server. It will be used as shared network storage.

This article covers the installation and configuration of the open source audio and video streaming service, Ampache. It is a web-based streaming application that allows you to upload your own audio/video contents and access them across multiple Internet-enabled devices. You can easily set up your home media server using Ampache and your old personal computer running Ubuntu. We will focus on installing Ampache on the Ubuntu server, but you can install Ampache on any Linux distribution of your choice.

In this article, we will cover the following recipes:

• Installing the Ampache server
• Uploading contents and creating catalogs
• Setting on-the-fly transcoding
• Enabling API access for remote streaming
• Streaming music with Ampache

In this recipe, we will learn to monitor Docker containers.

How to do it…

Docker provides inbuilt monitoring with the docker stats command, which can be used to get a live stream of the resource utilization of Docker containers.

To monitor multiple containers at once using their respective IDs or names, use this command:

$ docker stats mysql f9617f4b716c

With docker logs, you can fetch logs of your application running inside a container. This can be used similarly to the tail -f command:

In this recipe, we will learn to use a Docker network to set up a WordPress server. We will create two containers, one for MySQL and the other for WordPress. Additionally, we will set up a private network for both MySQL and WordPress.

How to do it…

Let's start by creating a separate network for WordPress and the MySQL containers:

A new network can be created with the following command:

$ docker network create wpnet

Check whether the network has been created successfully with docker network ls:

One of the most common questions seen on Docker forums is how to separate data from containers. This is because any data created inside containers is lost when the container gets deleted. Using docker commit to store data inside Docker images is not a good idea. To solve this problem, Docker provides an option called data volumes. Data volumes are special shared directories that can be used by one or more Docker containers. These volumes persist even when the container is deleted. These directories are created on the host file system, usually under the /var/lib/docker/ directory.

This recipe explores image creation with Dockerfiles. Docker images can be created in multiple ways, which includes using Dockerfiles, using docker commit to save the container state as a new image, or using docker import, which imports chroot directory structure as a Docker image.

So, we have installed the latest Docker binary. In this recipe, we will start a new container with Docker. We will see some basic Docker commands to start and manage Docker containers.

Getting ready

Make sure that you have installed Docker and set your user as a member of the Docker group.

You may need sudo privileges for some commands.

How to do it…

Let's create a new Docker container and start it. With Docker, you can quickly start a container with the docker run command:

In last few recipes, we learned about LXD, an operating system container service. Now, we will look at a hot new technology called Docker. Docker is an application container designed to package and run a single service. It enables developers to enclose an app with all dependencies in an isolated container environment. Docker helps developers create a reproducible environment with a simple configuration file called a Dockerfile. It also provides portability by sharing the Dockerfile, and developers can be sure that their setup will work the same on any system with the Docker runtime.
