Here, I use nsenter to solve the problem. Because I'm not familiar with go, and I don't have time to look at the basics, I chose this relatively simple method because I've done LFS before and I'm familiar with compilation. Download util-linux2.24:

Curl https://www.kernel.org/pub/linux/utils/util-linux/v2.24/util-linux-2.24.tar.gz\ | tar-zxf-cd util-linux-2.24./configure-- without-ncursesmake nsentercp nsenter / usr/local/bin

At this point, after the tool has been installed, run a container test:

Docker run-d-P training/webapp python app.py

Get the pid value of this container by parsing JSON:

PID=$ (docker inspect-- format'{{.State.Pid}} 'my_container_id)

Using the PID mentioned above, enter the container:

Nsenter-- target $PID-- mount-- uts-- ipc-- net-- pid

I can already operate in the container.
