lookup_plugins = plugins/lookups
filter_plugins = plugins/filters

gathering = smart
hostfile = inventory
host_key_checking = False

# Set color options
nocolor = 0

timeout = 120

[ssh_connection]
pipelining = True
ssh_args = -o ControlMaster=auto -o ControlPersist=60s -o TCPKeepAlive=yes -o ServerAliveInterval=5 -o ServerAliveCountMax=3

i found the issue. python was not installed in any of the container. so i made change in container_create.yml as below and it work fine for me .

Path : os-ansible-deployment-kilo\playbooks\roles\lxc_container_create\tasks\container_create.yml

at line 284 :

before : apt-get -y install python2.7

After : apt-get -y install python

after this it worked for me

i am not sure is it bug or not but it worked form me once i changed.

[Jesse Pretorius (jesse-pretorius)]

@chandu Are you using your own container image? The reason I ask is that the container image that's downloaded by default already has python installed into it. Also, please indicate which branch/tag you were installing from?

[Chandra (reddydodda)]

Hi Jesse ,

i am not using my own container. the default one which will be picked from https://mirror.rackspace.com/rackspaceprivatecloud/container_images/rpc-trusty-container.tgz

 and the branch which i am using is KILO.

One part of the problem seems to have been:

Another part of the problem related to how the image was build, and this was resolved in:
