# Stage 1: Builder
|
||||
# We use a lightweight Wolfi image to gather the files.
|
||||
# In a real build process, this might involve 'npm run build', but for static files,
|
||||
# we just copy them. Using a stage here allows for future extensibility.

||||

# Copy all files to the builder stage
|
||||
COPY . .
|
||||
|
||||
# Stage 2: Final
|
||||
# Use the official Wolfi base image and install Caddy manually
|
||||
# since the pre-built Caddy image requires authentication or is restricted.
