|---|---|---|
| dimitern | anyone around? | 07:31 |
| dimitern | I'm thinking of creating a simple subordinate charm that has actions returning various networking settings - iptables, routes, etc. | 07:31 |
| dimitern | So, can a subordinate have actions of its own? | 07:31 |
| lazyPower | dimitern: it can | 08:00 |
| dimitern | lazyPower, yeah, I've even found a good example with the chaos monkey | 08:01 |
| dimitern | :) | 08:01 |
| lazyPower | +1 for that | 08:02 |

| dimitern | lazyPower, hey, still around? | 11:05 |
| lazyPower | o/ dimitern | 11:05 |
| dimitern | lazyPower, I have a couple of actions questions if you have some time | 11:06 |
| lazyPower | surely | 11:06 |
| dimitern | lazyPower, so is there an accepted way to implement an action like "run something and get me the output" ? | 11:07 |
| dimitern | lazyPower, like, should the output be a param? or it could be dumped (without extra YAML) by action do / fetch | 11:07 |
| lazyPower | i dont think the output necessarily needs to be a param unless you need dynamic output data. action-set will take care of giving you the data points you care about. | 11:08 |
| lazyPower | a really good overview of this can be seen by the benchmark actions marco's team implemented. let me fish up one, 1 sec | 11:08 |
| dimitern | ah, that'll definitely help | 11:08 |
| lazyPower | https://github.com/juju-solutions/siege | 11:08 |
| lazyPower | notables: siege is paramterized, the output is parsed from json and stashed in the action dictionary for the run | 11:09 |
| lazyPower | that should get you a good start w/ how to implement a well-defined action, and have meaningful results available to consume outside of your env. | 11:09 |
| dimitern | thanks a lot! I'll look at that in detail | 11:10 |
| marcoceppi | dimitern: you should never just dump yaml | 11:11 |
| marcoceppi | dimitern: use action-set instead to relay data back | 11:11 |
| lazyPower | morning marcoceppi | 11:12 |
| dimitern | marcoceppi, but action-set returns YAML (or JSON I guess) - is there a way to dump a given param as-is? | 11:12 |
| lazyPower | action-set returns something? thats news... | 11:13 |
| dimitern | lazyPower, sorry, I meant juju action fetch <ID> | 11:13 |
| lazyPower | dimitern: did you mean juju action fetch? | 11:13 |
| lazyPower | ok | 11:13 |
| lazyPower | :) | 11:13 |
| dimitern | :) | 11:13 |
| lazyPower | i was like "uh oh, what changed" | 11:13 |
| lazyPower | yeah, no the fetch aiui returns the full data feed, you cannot narrow it down to specific keys without parsing it | 11:14 |
| lazyPower | maybe in a future revision? | 11:14 |
| dimitern | right, well if it does - it does, I'll parse it then :) | 11:14 |
| lazyPower | some fancy jq combined with --format=json | 11:14 |
| dimitern | yeah, it'll help to have "juju action fetch <ID> [param], returning only that part of the results | 11:15 |
| dimitern | lazyPower, so no concept of "output params", e.g. in that example doing a db backup and taking outfile=foo.tar.bz2 | 11:16 |
| dimitern | this won't actually mean foo.tar.bz2 will be created in the $PWD where you run juju action fetch | 11:17 |
| lazyPower | i would suggest you provide fullpath to foo.tar.bz2, that way you can parse that key and pipe that to juju scp | 11:17 |
| dimitern | right | 11:18 |
| lazyPower | But i dont think its possible to set file contents like that and have it automagically fetched. its a 2 step process | 11:18 |
| lazyPower | run proc, get data, action on data. | 11:18 |
| dimitern | yeah, unless fetch provides the sync-point where the foo.tar.bz2 gets created when fetch is called in a certain way | 11:19 |
| dimitern | lazyPower, the tip about jq is awesome though! | 11:21 |
| dimitern | thanks :) | 11:21 |
| lazyPower | np happy to help dimitern :) | 11:25 |

| lazyPower | marcoceppi: silly question, i know how to trigger relations on another host out of band, eg: mysql:17 - but if i'm same host, and in a different relationship context - are there any amenities to help me kick off a *-relation-changed event aside from caching relation data thats missing, and stuffing that in a direct execution to the hook? | 12:39 |
| marcoceppi | lazyPower: you mean, kick off a relationship on the same unit that you're currently running a hook? | 12:40 |
| lazyPower | yeah. I'm in a position to proxy data between hook contexts | 12:41 |
| marcoceppi | lazyPower: like, service foo has a bar and baz relation, kick off bar from the baz relation? | 12:41 |
| lazyPower | yep | 12:41 |
| marcoceppi | not really, just need to abstract away the underlying code for bar so that it's invokable from baz, like a pyhton method | 12:41 |
| lazyPower | when i relation_set(baz, mydata) - it triggers execution on the remote host, not the same host. | 12:41 |
| marcoceppi | right | 12:41 |
| lazyPower | ok, i figured taht would be the case | 12:42 |

| marlinc | Is it possible to take advantage of OpenStack security groups when using Juju to deploy services? | 21:08 |
| jrwren | marlinc: to what end? | 21:14 |
| marlinc | Well I would like to setup security groups to firewall off some machine parts | 21:14 |
| marlinc | Like giving a webserver only access to the ports that NFS uses for storage | 21:15 |
| marlinc | And its only possible to for example access the webserver on port 80 | 21:15 |
| jrwren | marlinc: i cannot answer. sorry. | 21:18 |
| marlinc | No problem | 21:19 |
