|
#
|
||
|
|
# The build context is the REPOSITORY ROOT, not apps/cms: this is a pnpm
|
||
|
|
# workspace, so pnpm-lock.yaml, pnpm-workspace.yaml and .npmrc all live one
|
||
|
|
# level up and pnpm refuses to do a frozen install without them.
|
||
|
|
#
|
||
|
|
# docker build -f apps/cms/Dockerfile -t sharper-cms .
|
||
|
|
# docker compose build cms # does exactly that
|
||
|
|
#
|
||
|
|
# Debian slim rather than Alpine: Strapi's image pipeline (sharp) ships glibc
|
||
|
|
# prebuilt binaries, so this avoids a source build of libvips.
