In this article, let's talk about Docker.
<h1 class="pgc-h-arrow-right" data-track="3" > what is Docker</h1>
Docker is an open-source application container engine that allows developers to package their applications and dependencies into a portable image and then release them to any popular Linux or Windows operating system, as well as virtualization. Containers are completely sandboxed and will not have any interfaces with each other.
Using Docker, you can virtualize an interface that is identical to the underlying hardware functionality, helping users quickly build, test, and deploy applications without worrying about environmental compatibility. To put it simply: the environment of a hardware is simulated through software technology.
Using Docker to package all the environments that a software needs to execute in a container, we can get the container up and running anywhere we have Docker installed, no longer need to rebuild the environment every time, and don't have to think about the installation problems on different machines, which is where Docker is most powerful.
As an emerging form of virtualization, Docker has many advantages over traditional virtual machines. First, Docker containers are a lightweight technology that starts very quickly, much faster than traditional virtual machines; second, Docker utilizes system resources so well that thousands of Docker containers can be executed simultaneously on a single host if conditions permit.
<h1 class="pgc-h-arrow-right" data-track="8" > why use Docker</h1>
Advantages of Docker: efficient, convenient, and system resource-saving.
We can imagine such a scenario, when you are ready to upload to the server after the local development, you find that the server system is not the Ubuntu you are familiar with instead of CentOS, in addition, you also need to install php7, set the MySQL account password and set up Apache, and every time you have to repeatedly build these environments, think about it is a headache. Moreover, the traditional virtual machine method of executing 10 different applications requires starting 10 virtual machines, while Docker can execute only one of the applications, and the consumption of additional system resources is minimal.
That's when you need Docker.
<h1 class="pgc-h-arrow-right" data-track="12" > Docker's application in NAS</h1>
First of all, we need to know that Docker is not a traditional virtual machine, it is a container. We put a program into this container and the program can run on any platform where Docker is installed. For example, a Transfer in Docker can run on AW's machine, or it can run on Synology and Tieweima's machine, and developers do not need to compile different program versions for different NAS platforms.
There are rich image resources in Docker Hub for users to download and use directly. Here are a few easy-to-use, powerful and NAS-friendly Docker deployments.
Many small partners install Container Station for the first time is the English interface, at this time we only need to switch the automatic detection to Chinese Simplified in the language bar in the upper right corner of the system, and the software will automatically replace the Chinese interface.
The original Docker needed to run through instructions, which is a bit of a threshold. Container Station has a clear and user-friendly control interface, we can search and download programs directly in the creation, without the need to enter complex instructions.

Graphics management tool Portainer
Portainer is a visual container image graphical management tool, can provide users with status display panel, application template rapid deployment, upload/download image and other basic operations, event log display, container console operation and other maintenance and management functions, basically to meet the needs of individuals and small and medium-sized units for container management, free of charge.
Navigation optimization Heimdall
Heimdall is a tool for optimizing navigation pages, with a single function but very practical. For example, I, a QNEWS nas user, even though QTS has been upgraded to version 5.0, still has not changed the icon cover of the traditional navigation page, which makes me look very unhappy with this appearance association. Heimdall is a tool to deflate me, and with it I can adjust the page labels, icons and backgrounds at will, which is simple and easy to use.
NAS download artifacts qBittorrent and Transfer
qBittorrent and Transfer are two tools that users hail as download artifacts, supporting torrents and magnetic link downloads. The two tools have their own advantages, qB speed is fast, suitable for rush upload, but the resource occupation is relatively high; Tr is more stable, suitable for seed preservation and management. If you want to pursue the ultimate speed, you can use qB, if you use Tr for the purpose of seed preservation.
BaiduNetdisk
BaiduNetdisk needless to say, a network disk hangs up to download the artifact.
For the knowledge of the notes Wiznote
Weizhi Notes is a cloud service note-taking tool that also has the functions of sharing data and collaborative editing, and the data can be synchronized and consistent on different devices. It makes up for the shortcomings of QNAP without Cloud Note PC software.
<h1 class="pgc-h-arrow-right" data-track="29" > Unicom equipment</h1>
QNAP TS-451D is a 4-bay NAS that supports 3.5-inch HDDs and 2.5-inch SATA-mounted SSDs, 64-bit X86 architecture, 4G DDR4 memory (expandable dual-channel 8G). This device has 4 USB 3.2 Gen1 interfaces and dual Gigabit network interfaces, supports 4K HDMI video playback, and the hardware configuration can fully meet the needs of ordinary home users and small studios. Objectively speaking, the QNAP TS-451D is really a rare entry-level model, with sufficient hardware and high playability.
QNAP NAS TS-451D ¥2499 Purchase
With the TS-451D hard drive, I chose the more popular Western Digital Red Disk Plus 4TB*4, and the capacity of 16T is enough for me to work, play, store movies, and backup files.
WD Western Digital MECHANICAL HARD DISK ¥879 purchase
Western Digital Red Disk Plus is a 3.5-inch hard drive optimized for NAS, using cmR vertical architecture (traditional magnetic recording), with better performance and faster RAID rebuild capabilities than earlier SMR tile magnetic recording. It is also equipped with NASWare 3.0 technology, which effectively improves NAS storage performance while reducing hard disk problems such as stability, power consumption, and noise common in NAS systems. In the event of a sudden power outage, NASWare 3.0 shuts down the running commands before shutting down, reducing data corruption.
Docker is widely used, I will share more about the operation and use experience of NAS Docker software in this column in the future, so stay tuned.
