Docker

AI Development Over Two Years: Somewhat similar to the state before a Docker release – fragmented and rapidly evolving.

Artificial Intelligence (AI) has undoubtedly been one of the most hotly debated topics in the technology field in recent years, particularly over the past two years, with AI technology experiencing rapid advancements. Whether it’s deep learning, natural language processing, or computer vision and automated decision systems, the application scenarios for AI are constantly emerging. However, despite continuous technological breakthroughs, AI still faces a bottleneck similar to that of a Docker release – a lack of a killer app to truly ignite the market.

Docker Domestic Mirror Proxy Failed

Deploying Docker on domestic servers, after deployment, if the company doesn’t provide a registry center, the first thing developers need to do is configure a domestic registry mirror address. It’s lucky that today there was a server configured with a registry mirror address, but when pulling images, it kept failing to pull.

Error response from daemon: “https://registry-1.docker.io/v2/”: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

Troubleshooting and Repair Attempts

Initially, we attempted to switch to alternative mirror acceleration addresses, hoping to resolve the issue. However, as expected, the problem persisted.

Office migration, the servers are inaccessible.

Administrative notice, office relocation from the second floor to the fifteenth floor – a standard, routine desk move.

Office Building

Migration

Closing up shop, packing everything away, a familiar route, a new workstation – adjusting computer cabling, finding a comfortable posture to start working. (ÒωÓױ)! – Connecting the network cable, the servers frequently used by the team were inaccessible. I tried switching to wireless networking, and access was normal again.

Docker Basics, Intermediate, and Advanced

Having worked with CentOS for many years, content may not apply to macOS or Ubuntu users in some cases.

You can refer to the documentation from Tsinghua University for installation guidance: https://mirrors.tuna.tsinghua.edu.cn/help/docker-ce/

Installation

Due to unknown mysterious forces, domestic Docker installation is recommended to set the cloud vendor’s repository address. Here we recommend using Alibaba Cloud.

Set Repository Source Address 

yum install yum-utils device-mapper-persistent-data lvm2 && \
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

Deploy the Latest Version

Docker is a commonly used background service, we recommend setting it to start on boot. The following command applies to CentOS 7:

Linux Setup JMeter Test Environment

The author has a strong interest in hardware and used JMeter to conduct load testing, documenting the process of deploying JMeter, InfluxDB, and Grafana on CentOS 7. They shared installation and command usage for JMeter, InfluxDB’s features and Docker installation method, as well as a simple deployment and configuration for Grafana. They summarized experience and references related to high-performance programming patterns.

Background

As widely known, I have a very strong interest in hardware. By chance, the test team was using JMeter to perform load tests and discovered that performance wasn’t improving. As a curious individual, I decisively took action to see how the company conducted its testing. There’s also a small story: at some point in the distant past, I read a post on OpenChina about how to create more impressive-looking performance test graphs – after observing Windows versions execute tests and achieving visualized TPS data display, what’s the use of configuring a web panel?
