Alpine Linux

Compared to Debian or Ubuntu container images, Alpine Linux uses one-tenth the space and 60% less RAM. It has minimal packages installed by default which minimizes the attack surface. That makes Alpine an ideal OS for both a Docker host and simple containers. Installing Docker in an Alpine Linux container on Proxmox is really as simple as running a few commands.

Alpine Linux is a lightweight, security-focused distribution that uses musl, libc, and busybox by default. It is an excellent choice for Proxmox LXC containers when you want minimal resource usage, fast boot times, and a small disk footprint. Choose Alpine for running services like Docker hosts, monitoring tools, or simple servers inside Proxmox.

Pi-hole is a popular caching DNS server used for blocking ads network wide. Keepalived allow servers to failover virtual IPs. Today I'll be configuring 3 Pi-hole servers with Keepalived so that no DNS IP ever goes down. While DNS is designed with failover in mind, some services and devices really don't play well with that.
