# Multi-stage Dockerfile for Diesel Depot.
|

|
|
# Designed for Coolify (which runs any standard Dockerfile on a Node host).
|
||
|
|
# Build context: the project root.
|
||
|
|
#
|
||
|
|
# Build: docker build -t diesel-depot .
|

|
# Run: docker run --rm -p 4002:3000 -e NEXT_PUBLIC_POCKETBASE_URL=... diesel-depot
|
||
|
|
#
|
||
|
|
# In Coolify, point the service at this Dockerfile. Coolify will set PORT
|
||
|
|
# (default 3000) automatically and inject any env vars you add in the UI.
