Mastodon Post / Thread How to increase Mastodon character limit WITHOUT forking!Tired of the "merge hell" when updating your custom Mastodon build? You can change the 500-char limit to 7500 (or more) while staying on the official Docker images.This works perfectly for Mastodon v4.3.0+ and @Coolify users! ️The Secret Sauce:Instead of rebuilding the image, we use Docker Volume Mounts to overlay two specific files and set Environment Variables.1️⃣ Backend: Create a local copy of status_length_validator.rb with MAX_CHARS = 7500.2️⃣ Frontend: Create a local copy of compose_form_container.js and set the fallback limit to 7500.3️⃣ Config: In your docker-compose.yml, mount these files and add:MAX_TOOT_CHARS=7500MAX_STATUS_CHARS=7500Why this rocks: Update-proof: Official updates won't overwrite your limits. Zero Build Time: No waiting for hours to compile assets. Mobile Ready: Tusky/Ivory will auto-detect the new limit via API.Full guide for sysadmins below! #MastodonAdmin #SelfHosted #coolify #Docker #Mastodon #fediverse
