How To Configure An Apache SSL Reverse Proxy on Linux?

~ Tom's IT Cafe ~ Leave a comment

What is Apache?

Apache is a free and open-source cross-platform web server software that allows users to deploy their websites on the internet. It was launched in 1995 and has been the most popular web server on the Internet since April 1996.

What is a reverse proxy?

A reverse proxy is a server that sits in front of web servers and forwards client requests to those web servers. It acts as an intermediary, intercepting and inspecting incoming client requests before forwarding them to the web server. Reverse proxies can provide additional levels of abstraction, control, security, and performance optimization. They are commonly used for load balancing, web acceleration, and to hide implementation details about the web servers.

What is SSL?

SSL, or Secure Sockets Layer, is a protocol for establishing authenticated and encrypted links between networked computers. Its current iteration is called TLS (Transport Layer Security).

Mastering Docker Networking: Exposing Ports Only to Other Containers

~ Tom's IT Cafe ~ Leave a comment

Docker networks are virtual networks created by Docker to enable communication between Docker containers, allowing them to connect to and communicate with each other or to non-Docker workloads. Containers inside the Docker network can talk to each other by sharing packets of information, and each container sees a network interface with an IP address, a gateway, a routing table, DNS services, and other networking details. By default, the container gets an IP address for every Docker network it attaches to, and when a container starts, it can only attach to a single network, using the –network flag. However, you can connect a running container to multiple networks using the docker network connect command.
