Hi Abdul,

I tried the steps on AArch64 platform, and hit error as below:

$ sudo docker build -t ${DOCKERAPP_TAG} -f Dockerfile.dpdkSampleApp .
Sending build context to Docker daemon   2.55GB

Makefile:44: *** "Please define RTE_SDK environment variable".  Stop.
The command '/bin/sh -c make && cp build/helloworld-shared /usr/local/bin/helloworld' returned a non-zero code: 2

Missing define of RTE_SDK and RTE_TARGET?
