# Build rootfs for php

build:
	@docker run --rm \
		-v $(CURDIR)/runner:/runner \
		-v $(CURDIR)/build:/build \
		-v $(CURDIR)/src:/src \
		imega/base-builder \
# this packages installed for your image
		--packages=" \
			git \
			php7@edge-testing \
			" \
# this packages installed for auxiliary tools
		-d="curl"

.PHONY: build

• -p --packages - this packages installed for your image
• -d --dev-packages - this packages installed for auxiliary tools

Start build

make build

You will receive a rootfs.tar.gz in a folder build.

Build your image

Put Docker file in project. e.g.

FROM scratch

ADD build/rootfs.tar.gz /

ENTRYPOINT ["php"]

run $docker run build -t test-image .

Runner scripts

You are allowed to use variables:

• $ROOTFS - This directory is the root of the file system.
• $SRC - This directory will be mounted in builder.

e.g.

You need to transfer configs in their way. Configs you place in SRC directory. Put command in entrypoint.sh

cp $SRC/daemon.sh $ROOTFS/app/daemon.sh
cp $SRC/rsyncd.conf $ROOTFS/etc/rsyncd.conf
