# Dockerfile for Hugo (HUGO=hugo) / Hugo Extended (HUGO=hugo_extended)
|
|
# HUGO_VERSION / HUGO_SHA / HUGO_EXTENDED_SHA is automatically updated
|
|
# by update.py when new release is available on the upstream.
|
|
# Utilize multi-stage builds to make images optimized in size.
|
|
|
|
# First stage - download prebuilt hugo binary from the GitHub release.
|
|
# Use golang image to run https://github.com/yaegashi/muslstack
|
|
# on hugo executable to extend its default thread stack size to 8MB
|
|
# to work around segmentation fault issues.
