build.sh

# Code by Jioh L. Jung <ziozzang@gmail.com>
# Original Code from https://github.com/gophergala/dnsp

#- Temporary Directory to build DNSP
DNSP_DIR=`mktemp -d -t dnsp.XXXXXX`

#- Build binary with Newest Golang
docker run --rm \
  -v ${DNSP_DIR}:/go/bin/ -v ${DNSP_DIR}:/usr/src/dnsp/ \
  -w /usr/src/dnsp/ \
  -e "CGO_ENABLED=0" -e "GOOS=linux" \
  --net=host \
  --entrypoint=/bin/bash \
  golang -c  \
  "go get -u github.com/gophergala/dnsp/... && true"

#- Copy Binary and Remove temporary directory.
cp -f "${DNSP_DIR}/dnsp" ./
rm -rf "${DNSP_DIR}"

#- Generate dockerfile to build
cat > dockerfile << EOF
FROM scratch
COPY ./dnsp /dnsp
entrypoint ["/dnsp"]
EOF

#- Build as docker images
docker build -t dnsp .

usage.md

• Generate whitelist file

cat > dnsp.whitelist << EOF
*.wikipedia.org
*.wikimedia.org
wikipedia.org
wikimedia.org
EOF

• Run as DNSP with docker.

# 1.1.1.1 is upstream dns server to resolve
# add '-t 0.0.0.0:8080' as option, to start webUI.
docker run \
  -d --name=dnsp \
  --restart=always \
  -v `pwd`:/data \
  --net=host \
  dnsp -r 1.1.1.1 --whitelist=/data/dnsp.whitelist
