Hi Ruifeng, I think you run you run the command in dpdk/extras. However, this 'Dockerfile.dpdkSampleApp' is expected to be run in dpdk's root dir so that it is mounted as '/opt/dpdk' in the second step above. I have tested this Dockerfile on Ubuntu 18.04 and compiled without any error. RTE_SDK is set correctly, but dpdk's directory is not mounted in the container. Abdul, >> +docker build -t ${DOCKERAPP_TAG} -f Dockerfile.dpdkSampleApp . I think this line should be corrected as following, and make it clear it should be run in dpdk's root. docker build -t ${DOCKERAPP_TAG} -f extras/Dockerfile.dpdkSampleApp . Even if the container image is built successfully, there is another problem in running app because it isn't run in privileged mode. root@0d2a309dfd2c:/opt/dpdk/examples/helloworld# helloworld EAL: Detected 16 lcore(s) EAL: Detected 1 NUMA nodes ...

You might have added $USER to docker group and run docker without sudo like as following. $ sudo groupadd docker $ sudo usermod -aG docker $USER I wounder it is better to use sudo in your examples, or add the instruction for users not familiar with docker.
