5// SanitizeDomainForContainer makes a domain safe for container naming.
6// It uses distinct replacements to avoid collisions between domains like
7// "git.example.com" and "git-example.com" (which would both become "git-example-com"
8// if we naively replaced all separators with hyphens).
9//
10// Replacements:
11//
12//	. → __ (double underscore, distinct from single _ in some conventions)
13//	: → -_ (hyphen-underscore combo, used for ports)
14//	/ → -- (double hyphen, distinct from colon to avoid :/ collisions)

22// SanitizeDomainForContainerLegacy uses the OLD (buggy) sanitization that replaces
23// all separators with hyphens, for backwards compatibility.
24//
25// IMPORTANT: This is maintained ONLY for finding old containers during upgrades.
26// New containers always use the collision-resistant SanitizeDomainForContainer().
27//
28// Migration strategy:
29// - During binary upgrades, legacy containers are found using this function
30// - Old containers are stopped and removed, then replaced with new containers
31// - New containers use the collision-resistant SanitizeDomainForContainer() naming
32// - After all deployments are upgraded, this function can be removed in a major version
