[dpdk-dev] [PATCH v3] build: add dockerfile for building docker image

[Abdul Halim <abdul.halim@intel.com>]

Adding a Dockerfile with Ubuntu bionic base image to build dpdk as shared
library. This docker image could be used as base image to build and run
dpdk applications in containers.

Signed-off-by: Abdul Halim <abdul.halim@intel.com>

---

v2:
  * renamed Dockerfile name from Dockerfile.ubuntu to Dockerfile.bionic
  * added call to ldconfig to update cache of libraries to include newly
    installed DPDK libs

---

v3:
  * added example use-case of dpdk dockerfile in extras/README.md

+# Build DPDK Docker image
+
+To build a docker image run the following command from dpdk root directory.
+
+```
+DOCKER_TAG="dpdk"
+docker build -t ${DOCKER_TAG} -f extras/Dockerfile.bionic .
+```
+
+# Example of how to use this dpdk library image
+
+The following steps shows how to use the dpdk shared library container to build
+and run a dpdk application without having to build dpdk library for each
+application.
+
+## Create a dpdk sample app docker file with 'dpdk' as the base image
+
+Create a docker file to build the dpdk helloworld application. Since, we are
+creating a docker file for dpdk helloworld app we need to add the dpdk source
+files, thus create the following docker file in dpdk root directory.
+
+```
+cat << EOF > Dockerfile.dpdkSampleApp
+FROM dpdk
+
+ADD . /opt/dpdk
+
+WORKDIR /opt/dpdk/examples/helloworld
+RUN make && cp build/helloworld-shared /usr/local/bin/helloworld
+EOF
+```
+
+## Build sample app docker image
+
+```
+DOCKERAPP_TAG="dpdk-helloworld"
+docker build -t ${DOCKERAPP_TAG} -f Dockerfile.dpdkSampleApp .
+```
+
+This sample app now can be run like any other applicaiton in a docker container.
+
+```
+$ docker run --rm -it  -v /dev/hugepages:/dev/hugepages dpdk-helloworld
+```
+
+## Running the sample app
+Once inside the container run helloword binary
+
+```
+$ root@11233ed2e69c # helloworld
+```
