Following the networking_ebpf instructions at https://github.com/ipdk-io/ipdk/blob/main/build/networking_ebpf/README_DOCKER.md#optional-vagrant-setup yielded the error shown below. SHould the instructions also include this step?

/git/ipdk/build/networking_ebpf/scripts/host_install.sh

Here is the error:

Looks like you missed the step to set the PATH variable
export PATH=/git/ipdk/build:$PATH before running the ipdk build.
Once if you set the PATH you will not see ipdk command error.

No issues observed till docker container image creation.
But, unable to run the demo "make start-demo" due to missing the folder “go” under /home/vagrant
Somehow go folder is getting created under /root/ instead of /home/vagrant
Needs further debugging.

Thanks, I confirmed that setting the PATH solved the docker image build issue. Can't this PATH export be done automatically by the build scripts? Why add a manual step?

Unfortunately not... Because the script is running in its own shell environment exporting a extended path will be gone when the script ends. 😢

Starting a new bash shell or logging in again should do the work also...
