Does APP_VERSION actually do anything?

Specifically for the Docker version since this is in the "REQUIRED: DOCKER SPECIFIC SETTINGS" section of the .env file?

APP_VERSION is not a Laravel/runtime setting inside Snipe-IT. In the Docker Compose setup it is only used for image-tag substitution:

image: snipe/snipe-it:${APP_VERSION:-latest}

So it controls which Docker image tag Compose pulls/runs when you use that compose file. If it is empty, Compose falls back to latest.

Once the container is running, the app version shown by Snipe-IT comes from the application code baked into the image, for example config/version.php. Changing APP_VERSION in .env will not change the displayed version or upgrade/downgrade the running app by itself.

Practical rule:

• using the provided docker-compose.yml: set APP_VERSION=8.1.17 or whatever tag you want, then docker compose pull and recreate the container;
• using your own explicit image: snipe/snipe-it:<tag> line: APP_VERSION does nothing unless your compose file references it;
• leaving it blank means "use latest", which is usually less deterministic for upgrades.

If that answers it, please mark the answer so the next Docker user knows this is just the image tag selector.

That seems like the answer. This should probably be noted in the compose file or Docker setup documentation since it's referenced several times and if the version is manually set then this does nothing. Thanks!
