So I would be concerned about it being called Dockerfile.ubuntu, because
at the moment it only covers Bionic, and Xenial is still supported until
April 21. The pattern FD.io VPP adopts is calling it Dockerfile.bionic.

Is it safe to remove /tmp/dpdk, then remove the WORKDIR.
Should be the other way around?

I will rename this file to Dockerfile.bionic as suggested.

The WORKDIR instruction sets the working directory for any RUN, CMD, ENTRYPOINT, COPY and ADD instructions that follow it. It is very much like 'cd' into a location for other commands to run in there. Once the dpdk build is finished successfully and library is installed we no longer need the source files in the final image. So, we can safely remove it and the subsequent ' WORKDIR /' instruction below ensures that WORKDIR is set to a valid location.

Hi Abdul,

I have tested your Dockerfile and confirmed that shared lib is generated 
under /usr/local as described in the Dockerfile.

Just a comment, I wonder if you add an example of usecase in 
documentation for helping users understanding how to use.

Regards,
Yasufumi

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.

I think '--privileged' option should be added to avoid the error.

$ docker run --rm --privileged -it  -v /dev/hugepages:/dev/hugepages 
dpdk-helloworld

I have one more suggestion. 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.

Yasufumi

Hi Yasufumi,
Thank you for your feedback.
The steps for creating the sample app docker file explains that that we 
are creating the file at dpdk root directory. So the assumption here is the docker 
run command also run from there. Not sure if we need to repeat this later also.

The 'cat' command above creates the docker file in dpdk 
root directory  for simplicity. Actually, we just needed the examples/helloworld 
source code from there. As for other user application, the docker file could
be anywhere, not necessarily in dpdk tree at all. User need to run docker build
from where their own docker file is.

The dpdk 'base' container should be used as shared-lib to build dpdk application
with libdpdk. So, the dpdk source code, RTE_SDK or RTE_TARGET is not needed
unless the pkg-config is unable to find libdpdk.

I will update the patch with suggested '--privileged' flag on docker run command.
Not sure if we should cover the docker permissions and docker specific 
configurations on  this doc though. I am sure user can find those resources 
somewhere else if needed. 

Hi Ruifeng,
Unfortunately I could not create Aarch64 environment to test this. Could you please
run the following command in your env and see if you can get output as below:

$ docker run --rm dpdk pkg-config --list-all | grep libdpdk
libdpdk          DPDK - The Data Plane Development Kit (DPDK).

Hi Yasufumi,

I ran the command in dpdk root dir which should be correct.
The issue was due to shared library image not been correctly built. See below.

Thanks.

Hi Abdul,

Yes, the issue was due to pkg-config could not find libdpdk. 
I didn't get expected libdpdk info in pkg-config output.

Just found that even my building of dpdk shared library image was failed.
Shared library image build failure was due to local 'build' directory in my
dpdk source tree. And the 'build' impacted meson configuration in container.

Not sure if it is a worth to mention that base dpdk tree should be clean.

With '--privileged' flag suggested by Yasufumi:

I am not sure the problem is always happened if the tree is not cleaned,

OK. It is just a suggestion. I though that it is better to include basic 
usage concisely, but no need if user can find it easily.

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

[Halim, Abdul]

Hi Yasufumi and Ruifeng,
Thanks for your feedback and verification.
I will update the patch with suggested changes and improve it little bit more to avoid the dirty build directory. 
Also, for the sample app I will copy examples/helloworld source code only in the docker file.

Regards,
Abdul

[dpdk-dev] [PATCH v4] build: add dockerfile for building docker image

[Abdul Halim]

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

---
v4:
  * changed meson build to use tmp dir in docker build
  * changed sample app dockerfile to add only helloworld source code

Hi Abdul,

Other's feel free to shoot me down. 
But I am not sure that HelloWorld is really the example we want to show here.

HelloWorld is good and it minimizes the associated config you need to describe.
However does it really help a someone get started running DPDK in a container, as there is no network interface. 

Is there anyway we could show something running on a network interface?
Perhaps we contrive something simple with vEth, AF_Packet and TestPMD?

You may want to rm /tmp/dpdk-build as well.

Hi Ray,
Our intent here is to show how to use this dpdk shared lib in container to build 
an application and run it. The same steps can be taken for any other advanced 
DPDK apps to take advantage of this shared library.
As you've mentioned, other apps will require various  HW related configuration 
to be shown and explained. The DPDK documentation already cover them 
in details. And that may unintentionally divert the focus to that particular app.
This is my opinion only :) 

However, if you strongly feel that the example should be with one of the apps
you've mentioned I can update it accordingly.

Many thanks!

Regards,
Abdul

[dpdk-dev] [PATCH v6] build: add dockerfile for building docker image

[Abdul Halim]

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

---
v4:
  * changed meson build to use tmp dir in docker build
  * changed sample app dockerfile to add only helloworld source code

---
v5:
  * fix whitespace error

---
v6:
  * clean up temp build directory

My simple point is that DPDK without a network card, is not the majority use case.
Dataplane Development Kit implies some sort of a network data plane :-)

Have to agree with Ray here. The DPDK build process is complex and robust enough
as is. Unless someone wants to go farther with container based build, it doesn't
look like this patch got any traction in 4 years so dropping it.
