failed at docker_node.py self.pid = int(ps_out[0])

[jeromesun14]

Same as bug p4lang/p4factory issue 193

Error log

  File "/xxx/ntf/docker/docker_node.py", line 145, in startShell
    self.pid = int(ps_out[0])
ValueError: invalid literal for int() with base 10: "'21431'\n"

Reason

docker_node.py, L145 self.pid = int(ps_out[0]), ps_out[0] is not a pure decimal string, but also including a \n which should be strip first.

Solution

change docker_node.py L145 to:

self.pid = int((ps_out[0].strip()).strip('\''))
