| geb | hello | 14:58 |
| geb | I am trying to understand https://github.com/openstack/tacker/blob/master/tacker/vnfm/mgmt_drivers/openwrt/openwrt.py would somebody be available for a few questions ? Main one : i don't understand how the code can add rules etc as it *seems* to only launch: cmd = "uci import %s; /etc/init.d/%s restart" % (service, package) | 15:00 |
| phuoc | geb, hi | 15:00 |
| phuoc | https://github.com/openstack/tacker/blob/master/tacker/vnfm/mgmt_drivers/openwrt/openwrt.py#L68 | 15:02 |
| phuoc | as you can see, Tacker call RemoteCommandExecutor which use ssh protocol to access the VM | 15:03 |
| phuoc | then execute commands on openwrt VM | 15:03 |
| geb | right, but, it seems to only launch 'cmd = "uci import %s; /etc/init.d/%s restart" % (service, package)' and no special command to add the rules etc | 15:04 |
| geb | or maybe i don't understand the code :) | 15:04 |
| phuoc | you mean that adds new rules, and still keep the old rules | 15:05 |
| *** bobh has joined #tacker | 15:06 | |
| geb | No. Sorry if i am not clear. As i understand the code, | 15:07 |
| geb | https://github.com/openstack/tacker/blob/master/tacker/vnfm/mgmt_drivers/openwrt/openwrt.py#L70 execute the command | 15:07 |
| geb | https://github.com/openstack/tacker/blob/master/tacker/vnfm/mgmt_drivers/openwrt/openwrt.py#L63 define the command executed | 15:07 |
| geb | however, the only commands which will be launched will be "uci import %s; /etc/init.d/%s restart" | 15:08 |
| phuoc | geb, that's right :-) | 15:08 |
| phuoc | Ahh | 15:09 |
| phuoc | I think I get your point | 15:09 |
| geb | this command will only add services, and not configure then, right ? | 15:09 |
| phuoc | geb, when you look at the line 70 | 15:11 |
| phuoc | there is input_data = config | 15:11 |
| phuoc | https://github.com/openstack/tacker/blob/a0675317375e217d30635f6d661d3f164256270f/tacker/common/cmd_executer.py#L80 | 15:11 |
| phuoc | the input_data will be executed by execute_command function | 15:13 |
| geb | yep, right, but how those input_data, won't end to be valid linux/openwrt commands ? https://github.com/openstack/tacker/blob/master/samples/tosca-templates/vnfd/tosca-config-openwrt-firewall.yaml | 15:15 |
| phuoc | hmm, you mean these config can be wrong | 15:17 |
| phuoc | and there are some problems? | 15:17 |
| geb | Well, i don't find the code that transform those "abstract" configuration values to proper openwrt/linux commands | 15:19 |
| geb | if https://github.com/openstack/tacker/blob/a0675317375e217d30635f6d661d3f164256270f/tacker/common/cmd_executer.py#L80 simply try to execute them as they are wrote in https://github.com/openstack/tacker/blob/master/samples/tosca-templates/vnfd/tosca-config-openwrt-firewall.yaml i don't understand how it will end in anything else than bash complaining about "command not found" :) | 15:22 |
| phuoc | ahh, you meet the error command not found :-) | 15:23 |
| geb | Well, i was trying to read the code before launching it ... Will try the inverse and maybe will it answer my questions :) | 15:26 |
| geb | Thanks a lot anyway, for the time you took to answer my questions :) | 15:27 |
| phuoc | https://github.com/openstack/tacker/blob/master/doc/source/install/deploy_openwrt.rst | 15:27 |
| phuoc | you can try that | 15:27 |
| phuoc | some guys updated the doc recently | 15:27 |
| phuoc | geb, you're welcome | 15:28 |
| geb | BTW, I am working in a research project to investigate about SDN/NFV, and choose to use tacker as a testbed. I had to adapt a bit the install procedure & kolla quickstart (for example to deploy in all in one). I took notes as a script which should be almost functionnal https://pastebin.com/RERqxx09. I would be happy to contribute it if there is any interest | 15:50 |
| haint_ | geb, we also research on NFV. Thank you for your contribution. | 15:56 |
| phuoc | geb, nice to meet you | 15:58 |
| geb | :) | 15:58 |
| phuoc | but that seems '/usr/local/share/' is missing :-) | 15:59 |
| geb | it should be here after pip install kolla-ansible | 16:01 |
| geb | https://docs.openstack.org/kolla-ansible/latest/user/quickstart.html | 16:02 |
| *** egonzalez has quit IRC | 16:03 | |
| phuoc | oops, that directory /usr/local/share/kolla-ansible/etc_examples | 16:03 |
| phuoc | I can not see etc_examples in kolla-ansible | 16:04 |
| geb | on ubuntu ? https://docs.openstack.org/kolla-ansible/latest/user/quickstart.html indicate a different path for centos | 16:08 |
| geb | But i don't not wrote the script to be run as it, mostly as notes, to have a simplier install procedure than https://docs.openstack.org/kolla-ansible/latest/user/quickstart.html & https://docs.openstack.org/tacker/latest/install/kolla.html (for example to use all-in-one, desactivate haproxy, and maybe after some other stuffs like neutron configuration, some vnf creation etc) ... I may end validating it, or using it as a base of a written documentation, as | 16:09 |
| geb | of now its only notes, in a shell script form :) | 16:09 |
| phuoc | geb, I will try your script, thanks ^^ | 16:18 |
| geb | phuoc, let me know how it works :). You may have to remove the second "install" mention in line 85 (pip install python-openstackclient python-glanceclient python-neutronclient install python-tackerclient networking-sfc). Just saw it after uploading | 16:22 |
