[PATCH] doc: using container to build and run applications

[Thomas Monjalon]

> +DPDK can be built inside a container to provide a reproducible build environment.

Changed "reproducible" to "isolated" as it is not always a reproducible build,
especially with "FROM fedora:latest".


> +Once the build completes, verify that the helloworld example runs:
> +
> +.. code-block:: console
> +
> +   podman run --rm dpdk-builder /dpdk/build/examples/dpdk-helloworld

Hugepages are not installed at this stage, so adding --no-huge is required.


They are small changes, done while merging after a quick test.
