If you have used Docker, you must understand daemons, containers, and their functions. A daemon is a service that runs in the background when a container is already in use in any system. Podman is a free management tool for managing and creating containers without relying on any daemon such as Docker. Therefore, it has advantages in managing containers without the need for long-term backend services. Additionally, Podman does not require root-level permissions to be used. This guide discusses in detail how to install Podman on Ubuntu24. To update the system, we first need to update the system and open the Terminal shell of Ubuntu24. During both installation and upgrade processes, we need to use the command line. a simple

According to Huawei’s official news, the Open Atomic Developer Conference, with the theme of “Everything for Developers”, was held in Wuxi for two days, from December 16 to 17. The conference was led by the Open Atomic Open Source Foundation, Huawei, and Inspur. , DaoCloud, Xieyun, Qingyun, Hurricane Engine, as well as the OpenSDV Open Source Alliance, openEuler community, OpenCloudOS community and other member units jointly initiated the construction of the AtomHub Trusted Mirror Center, which is officially open for public testing. AtomHub adheres to the concepts of co-construction, co-governance, and sharing, and aims to provide open source organizations and developers with a neutral, open and co-constructed trusted open source container mirror center. In view of the instability and uncontrollability of image warehouses such as DockerHub, and some

As a lightweight virtualization platform based on container technology, Docker has been widely used in various scenarios. In a production environment, high availability and automatic failure recovery of containers are crucial. This article will introduce how to use Docker for container failure recovery and automatic restart, including specific code examples. 1. Configuration of automatic container restart In Docker, the automatic restart function of the container can be enabled by using the --restart option when running the container. Common options are: no: do not automatically restart. silent

How to sort STL containers in C++: Use the sort() function to sort containers in place, such as std::vector. Using the ordered containers std::set and std::map, elements are automatically sorted on insertion. For a custom sort order, you can use a custom comparator class, such as sorting a vector of strings alphabetically.

The most common container types in C++STL are Vector, List, Deque, Set, Map, Stack and Queue. These containers provide solutions for different data storage needs, such as dynamic arrays, doubly linked lists, and key- and value-based associative containers. In practice, we can use STL containers to organize and access data efficiently, such as storing student grades.

Hello, I am Brother Zheng. WeChat's mini program is a very good experience, simple and quick to use. I have been learning to use mini programs these days. I have summarized three ways to use Python as the backend of mini programs for your reference. Method 1. WeChat cloud hosting [1]. Advantages: No need to purchase a server, no domain name registration required, billing based on usage, DevOps automation, security authentication, suitable for people with no operation and maintenance experience. Disadvantages: The cost is definitely slightly higher than the cost of building a self-built server. Just like the same model, automatic transmission cars are more expensive than manual transmission cars. The so-called cloud hosting is a Docker container. You only need to get a warehouse, which can be any of github, gitlab, and gitee.
