    Docker Networking Explained: Theory and Network Drivers Simplified

    Docker networking simplifies the configuration of network connections, enabling containers to connect with each other, the host, and external networks. It follows core networking principles using bridges and NAT for communication. Docker network drivers, including built-in options like bridge, host, overlay, and none, help in different scenarios by abstracting the underlying complexities. These drivers are crucial for the efficient deployment and operation of containerized applications, allowing developers to focus on functionality rather than infrastructure.

    NUT on my Pi, so my servers don't die

    Setting up Network UPS Tools (NUT) on a Raspberry Pi can help safely manage server shutdowns during power outages. By installing and configuring NUT on the Pi, it can monitor UPS devices and ensure servers shut down properly before battery depletion. The detailed steps include installing NUT, configuring the UPS, and setting up NUT server and clients. Additionally, integration with platforms like Home Assistant is shown to monitor UPS vitals and stats.

    How The Internet Actually Works

    Accessing a website may seem simple, but it involves a complex process of networking technology and infrastructure. Data is transmitted globally through fiber optic cables, managed by the Domain Name System (DNS), and transported via the TCP/IP protocol. This process includes URL mapping to IP addresses, DNS hierarchy queries, and a three-way handshake for data transfer. The entire sequence happens in milliseconds, ensuring efficient and secure web browsing.

    How Do Websockets Work ✨

    Websockets enable bidirectional real-time communication between client and server, making them more efficient than HTTP request response, short polling, long polling, and server-sent events for certain use cases. The process involves an initial handshake to open a connection, transferring data in frames, and a closing handshake to terminate the connection. Despite its efficiency, websockets require a persistent connection and come with server resource limitations.

    Docker Engine v28: Hardening Container Networking by Default

    Docker Engine v28 enhances security by ensuring containers are not unintentionally accessible from local networks. This update introduces default rules that drop traffic to unpublished container ports, protecting containers in multi-tenant and shared network environments. Users running Docker on Linux without customized firewall settings are advised to upgrade to benefit from these protective measures. The update emphasizes that unpublished ports remain private, and offers options for users who need the old behavior.
