INT: Unable to run the docker image for mininet-spine1

[Muthuramane]

Hi All,

I am try to run the apps/int but it had problem while running the docker.

parallels@ubuntu:~/p4lang/p4factory/mininet$ sudo ./int_ref_topology.py [sudo] password for parallels: ['docker', 'run', '-ti', '--rm', '--privileged=true', '--hostname=spine1', '--name=mininet-spine1', '-p', '26002:9091', '-e', 'DISPLAY', '-v', '/tmp/.X11-unix:/tmp/.X11-unix', '-v', '/home/parallels/p4lang/p4factory/mininet/configs/spine1/l3_int_ref_topo:/configs', 'p4dockerswitch', '/p4factory/tools/start.sh'] Traceback (most recent call last): File "./int_ref_topology.py", line 107, in run_cfg() File "./int_ref_topology.py", line 83, in run_cfg net = mgr.setupAndStartNetwork() File "/home/parallels/p4lang/p4factory/mininet/int_cfg.py", line 113, in setupAndStartNetwork self.addSwitches() File "/home/parallels/p4lang/p4factory/mininet/int_cfg.py", line 147, in addSwitches pps = s.pps, qdepth = s.qdepth) File "build/bdist.linux-x86_64/egg/mininet/net.py", line 240, in addSwitch File "/home/parallels/p4lang/p4factory/mininet/p4_mininet.py", line 148, in init Switch.init( self, name, **kwargs ) File "build/bdist.linux-x86_64/egg/mininet/node.py", line 855, in init File "build/bdist.linux-x86_64/egg/mininet/node.py", line 106, in init File "/home/parallels/p4lang/p4factory/mininet/p4_mininet.py", line 277, in startShell self.pid = int(ps_out[0]) ValueError: invalid literal for int() with base 10: ''

I ran the same command by manually

sudo docker run -ti --rm --privileged=true --hostname=spine1 --name=mininet-spine1 -p 26002:9091 -e DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix -v /home/parallels/p4lang/p4factory/mininet/configs/spine1/l3_int_ref_topo:/configs p4dockerswitch /p4factory/tools/start.sh docker: Error response from daemon: invalid header field value "oci runtime error: container_linux.go:247: starting container process caused \"exec: \\"/p4factory/tools/start.sh\\": stat /p4factory/tools/start.sh: no such file or directory\"\n".

The file start.sh is missing under the directory p4factory/tools/start.sh.

Please, any one know about this issue

Hi, The mininet scripts for INT will be hosted in a new repo. In the meanwhile, I recommend you to use NTF to run the mininet scripts for INT.

Thanks

INT example in p4factory has been fixed. Please refer link.

Thanks

Thanks @herlenashavi .

The problem was resolved.

Note that the top level README of this project points out that it is deprecated, and recommends looking at p4lang/tutorials instead, which has several people working on it, and thus you are more likely to get help with problems. It is fairly unlikely someone will be interested in helping you debug issues with the code in this repository.

@jafingerhut Thank you for your suggestions. I build the switch docker image and the VXLAN-GPE driver again, now everything is working perfectly.

Thank you.
