+# Build docker image
+
+We use a docker environment to build paddle binaries and put it into a runtime image `paddle-core` for uses of most cases
+
+***Notice***: do **not** run in this directory, run under the top level of this project like:
+
+```
+sh paddle/scripts/docker/buildall.sh
+```

paddle/scripts/docker/buildall.sh

+#!/bin/bash
+
+BINARIES_DIR=paddle/scripts/docker/buildimage/binaries
+
+function build_in_docker() {
+  docker build . -t paddle-build-env -f paddle/scripts/docker/buildimage/Dockerfile.build
+  BUILDER=$(docker run -d paddle-build-env)
+  docker exec $BUILDER /bin/bash -c "export BUILD_AND_INSTALL=ON && /paddle/paddle/scripts/docker/build.sh"
