'Auslauf' is derived from the separable verb 'auslaufen' (to leak / run out / sail out). This connection helps you understand the different meanings: a liquid leaks out, a product is phased out, a ship sails out of the harbor, and animals get exercise outdoors.
Pass auf, die Milch im Topf läuft gleich aus!
Watch out, the milk in the pot is about to boil over!
In connection with animals, the phrases 'Auslauf haben' (to have room to run) or 'Auslauf bekommen' (to get outdoor exercise) are often used. You can also 'Auslauf geben' or 'Auslauf gewähren' (give/grant an animal outdoor exercise).
Unser Hund braucht jeden Tag viel Auslauf im Park.
Our dog needs a lot of exercise in the park every day.
This meaning is used almost only for products or contracts. A very common word in this context is 'Auslaufmodell' (discontinued model / model being phased out), which describes a product whose production will soon end.
Dieses Sofa ist ein Auslaufmodell und deshalb im Preis reduziert.
This sofa is a discontinued model and is therefore reduced in price.
In the meaning 'departure of a ship', 'Auslauf' belongs to the technical language of seafaring. In everyday speech, people would more likely say 'Abfahrt' (departure) or 'Auslaufen' (sailing out).
Der Auslauf des Containerschiffs ist für 18:00 Uhr geplant.
The departure of the container ship is scheduled for 6:00 p.m.
end
'das Ende' and 'der Auslauf' can both describe that something does not continue. 'das Ende' is the normal and general word for the end of almost anything. 'der Auslauf' is narrower: in this meaning, it is usually about a product, model, contract, or regulation gradually no longer being available or valid. That is why 'Auslauf' often sounds like language from commerce, technology, or administration. For a film, a meeting, or a party, you normally say 'Ende', not 'Auslauf'.

Der Auslauf des alten Handy-Modells ist für den Herbst geplant.
The phase-out of the old mobile phone model is planned for the fall.
Nach drei Stunden kam das Ende der Besprechung für alle sehr plötzlich.
After three hours, the end of the meeting came very suddenly for everyone.
