What is the best way to get Docker container logs into Elasticsearch?
I have a go application running in a container that does a lot of logging: log.Println("Somethinghappened!") Since I can ssh to the server it's running on, I can do dockerlogs -f[id] to see stderr Output, it's all good. But now I want the logs to go into elasticsearch. What's the best approach?

Use vscode to remotely debug the Linux kernel
Preface The previous article introduced the use of QEMU+GDB to debug the Linux kernel. However, sometimes it is not very convenient to directly use GDB to debug and view the code. Therefore, on such an important occasion, how can the artifact of vscode be missing? This article introduces how to use vscode to remotely debug the kernel. Environment for this article: Windows 10 vs Code Ubuntu 20.04. I personally use Tencent Cloud Server, so I save the process of installing a virtual machine. Start directly from vscode configuration.

Embedded Linux Series Part 8: Operating Network Ports
1. Introduction Some relatively high-performance microcontrollers often have Ethernet interfaces. The network port is considered a relatively complex peripheral in the MCU because it involves the operation of the network protocol stack. Normally, the network protocol stack will run in a real-time operating system (RTOS), so it is difficult for ordinary microcontroller developers to use the network port. Under Linux, the network port is a frequently used interface, because Linux has a mature and complete network communication protocol stack, and the underlying driver has been provided by the manufacturer, so it is relatively convenient to use. This article will briefly summarize the use of network ports under Linux, hoping to be helpful to everyone. 2 Environment Introduction 2.1. Hardware\1) NUC made by a third party on the Internet

We can use it to manage many system services, such as telnet, ssh, ftp, etc. Most system services are started using inetd. The advantage of using it is that it can uniformly manage various services and set service rules through it, such as whether to block certain IP sources.

Instead of connecting to the server using a password, use a .pem certificate file (key) to connect to the server. 1. Generate the key file ssh-keygen-trsa-b2048-v Note: The connection method is basically the same as that of Git. If you have previously generated public keys and keys for authentication by Git, use the default path ~/ .ssh/id_rsa, pay attention to switching paths and names to avoid overwriting effects.
