As of 4768cae6, we can use conserver/telnet to connect to the docker0
bridge IP:90XX, where XX is DUTXX. This was a great UX improvement
and this patch set aims to further the experience by:
- allow running Infamy (infix-test container) completely rootless¹
- reduce the expsed port range 50->10 (can be improved further)
- use 'podman --publish-all' ports, which allocates ten random
ports for the exposed Qemu telnet ports
- add Quick Start Guide to doc/testing.md
This restores the possiblity of running multiple "make test-sh"
instances, e.g., when multiple users share the same server.
The 'console' script included in this commit uses 'podman inspect' to
find the port number for a given DUT, and optional instance. It takes
either the console/dut number (1-N), or the dut name from the topology.
Also in this commit:
- set hostname for easy identification (for console script)
- set conatainer --name to hostname
- adjust workdir from buildroot to infix/test
- simplify PS1 and add time to prompt (when did the test finish?)
When running 'make test-sh' the prompt now tells you which instance you
are running, e.g., infmay10. Calling 'console 1 infamy10' connects to
console 1 (port 9001) on the infamy10 instance.
For more information, see the Quick Start Guide in doc/testing.md. It
shows how to use the new helper scripts: console and shell.
Fix #227
_______
¹) devs using podman, instead of docker, with slirp4netns installed, can
run the infix-test container completely rootless. We like this, and
as of today podman is our recommendation.
