Re: openstack hard depency or not
2013/11/17 Maarten Ectors maarten.ect...@canonical.com: Juju works on AWS, hp cloud, azure, etc. and very soon many more. If you use servers via MAAS then you can use containers to put multiple charms on one server. Each container has its own IP address hence different charms can listen to the same port without a conflict. Soon this same functionality will be available on more platforms. Maarten Thanks for answers. My new question is - does it possible to have one state server for all customers? I don't need to spawn sepaate state server for each customer deploy, but want to provide to it some log/pass/key to acces state server and use it.

Re: openstack hard depency or not
2013/11/18 John Arbash Meinel j...@arbash-meinel.com: Given that you can run multiple services on a given machine, is there a strong reason that multiple state servers are a problem for you? (I want to make sure if there is a use case that is a problem our solution actually covers it.) As i see , clients that want wordpress or something else does not want to create unneeded things. After they installs wordpress (for example) they can test it and works with it. After sometime if all goes ok thet want to add load balancer and something new to it. But i don't think that all time they need state server. I think best of all spawn state server on demand. For example user interact with juju with provided keys, my own server (or such thinkg) check incoming key and spawn lxc container with state server and proxy to it (or this can be do it in state server itself). -- Vasiliy Tolstov, e-mail: v.tols...@selfip.ru jabber: v...@selfip.ru -- Juju mailing list Juju@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/juju

Re: relations system in juju
2013/11/22 William Reade william.re...@canonical.com: Hi Vasiliy There's some moderately high-level documentation of what happens in doc/charms-in-action.txt in the juju-core source tree, but that doesn't really get into the details. If you're interested in diving through the code, the most fundamental piece is the state.RelationUnit type (state/relationunit.go): its EnterScope, LeaveScope, and Settings methods are responsible for the inputs into the system, and the Watch method (implemented in state/watcher.go) is responsible for pulling all those changes into a stream of events for consumption by the units. The worker/uniter package -- particularly relationer.go, and the relation subpackage -- are the clients responsible for turning that stream of events into actual hook executions. At heart, it all depends on Gustavo Niemeyer's mgo driver for mongodb on golang; we manage db changes with the mgo/txn package, and (in juju-core again) the state/watcher package turns the transaction log into events consumed by the RelationUnitsWatcher.

supported operation systems and other questions
Hi. I have vps service that needs quickly provide vps to end users with pre-created applications like hosting panels or cms. Before that i have handmade chef-solo scripts that install some software. But this way not work's well. Firstly because i maintain all the code. Now i need to create not one vps but 2,3,4 with relations between each other. I see on juju and terraform (https://www.hashicorp.com/blog/terraform.html) and thinks that it can provide me needed features. Basic usage - one vps for all that need for application (for example for wordpress - mysql, php, nginx, memcached...), but to provide for end user ability to grow/separate services as needed. I'm install vps from packer images (this provide 100% chance to install vps and takes about 20-30 secs to deploy). But in case of juju - what is the best way to deploy applications? Run juju on already created user vps, or i can run juju and configure all applications inside packer and reconfigure it then vps installed and running? Also as i see many charms hardcoded deps via apt-get install. But what platform supported? Ubuntu only or debian? How ca i deal if user wants to get application on centos 7 ? I need to rewrite charm or i have some dsl (like in chef) to install software based on running platform?

proper way to deploy to one server (lxc based)
Hello. What is the recommended way to install all-in-one (for example wordpress) and publicly available server?

After that i need to go to my wordpress site, but nginx listens for connections inside container. Now i'm create nat rule inside iptables by hand... But does it possible to do it automatic?

I think that if all charms have like mysql tuning option to set maximum memory usage by it service and ability to get all services running on current machine is enough. /usr/bin/free not helps, because many services does not have constant memory usage all of the time.

Re: move already deployed service to new vps with different ip address.
2014-10-15 11:08 GMT+04:00 John Meinel j...@arbash-meinel.com: You could probably edit the /var/lib/juju/agents/unit-*/agent.conf and /var/lib/juju/agents/machine-*/agent.conf to change the IP addresses stored there (everyone needs to know how to get back to the API server). Generally the API server filters out 127.0.0.1 when reporting its possible addresses to other units, since *most* of the time they can't actually contact it at 127.* In fact, the only time it works is when they are colocated, if you used containers or VMs the 127.* address wouldn't ever work. And generally colocating your services with the API server is considered a security issue. (You have to give your cloud credentials to the API server if you want to let it start instances for you, but that information should not be available to the services you deploy.) If you did deploy into containers (like juju deploy --to lxc:0) then the services would be isolated, and likely the API server would get a 10.0.3.1 address, which could be preserved between packing it up and putting it somewhere else. Problem not in state server, as i see in wordpress config i have address 10.0.2.15 as i understand in relation-change than i'm attach mysql it gets it public_ip (that can't be 127 as it ignored).

Re: gocharm help
2015-04-23 11:00 GMT+03:00 roger peppe roger.pe...@canonical.com:
Nice start!
As far as I can see the issue is just that there's
a variant syntax of a relation that's allowed in the metadata
(I replied in the issue itself).
I had a brief look at your hooks.go file. I'd suggest that
it's probably better to register the hooks individually,
rather than using the switch (that way gocharm does the
work).
As it happens, the gocharm hook logic emits a log message
anyway when a hook starts and finishes, but if you
*do* want to wrap other generic logic around hooks, it's
probably better to use a decorator style than to
introduce the switch.
e.g.
func (n *mysql) registerHook(r *hook.Registry, name string, h
func() error) {
r.RegisterHook(name, func() error {
n.ctxt.Logf(running %s, name)
return h()
})
}
...
n.registerHook(r, install, n.install)
Here's a paste of the code with a few suggested changes made:
http://paste.ubuntu.com/10870074/
Please let me know if you have any more issues (or, even better, if
it all just works ok for you :-] )
Thanks for suggestions, i'm try to write simple wordpress charm and
check relations =)
Last question - what benefits of using simplerelation package or

Re: add users to already deployed ftp server charm
2015-06-03 2:16 GMT+03:00 Charles Butler charles.but...@canonical.com: Vasilly, this would be a prime opportunity to extend the charm with a Juju action! https://jujucharms.com/docs/devel/actions You can somewhat extrapolate different data types for action variables by defining a string and loading it with say, a JSON object with the properties you need and then parse it server side. But I dont like this as it breaks expectations of what the value type should be. What I personally would do, is create an action to add a single user w/ the proper data points as an action, and script calling that action with whatever data-sets you need.

Re: What's coming for Juju in 14.04
2013/11/21 Jorge O.

Most everything else looks like polish, stability, and reliability improvements across the board, or things like having the CLI talk to the API directly which is nice but probably won't affect the end user facing bits too much. Small features like `juju quickstart` will also make the overall experience nicer. From the non-core side having the Charm Tools and Charm Helper improvements along with the charm audit will probably have a greater impact on day to day usage of Juju overall as we continue to build tools around the ecosystem to make it more useful for people.

Re: gocharm help
2015-04-23 11:00 GMT+03:00 roger peppe roger.pe...@canonical.com:
Nice start!
As far as I can see the issue is just that there's
a variant syntax of a relation that's allowed in the metadata
(I replied in the issue itself).
I had a brief look at your hooks.go file. I'd suggest that
it's probably better to register the hooks individually,
rather than using the switch (that way gocharm does the
work).
As it happens, the gocharm hook logic emits a log message
anyway when a hook starts and finishes, but if you
*do* want to wrap other generic logic around hooks, it's
probably better to use a decorator style than to
introduce the switch.
e.g.
func (n *mysql) registerHook(r *hook.Registry, name string, h
func() error) {
r.RegisterHook(name, func() error {
n.ctxt.Logf(running %s, name)
return h()
})
}
...
n.registerHook(r, install, n.install)
Here's a paste of the code with a few suggested changes made:
http://paste.ubuntu.com/10870074/
Please let me know if you have any more issues (or, even better, if
it all just works ok for you :-] )
Thanks for suggestions, i'm try to write simple wordpress charm and
check relations =)
Last question - what benefits of using simplerelation package or
writing own relations packages?

2015-05-27 3:17 GMT+03:00 Kapil Thangavelu kap...@gmail.com: relation settings only propagates private ip, which juju sets, and its imo bug that juju should update and invoke relation change hook if it changes and has the previously set value (ie. thus works w/ proxy charms). at least that was my summary going in and out of the that monster thread. at the moment juju doesn't update the addresses it set, but it will invoke config-changed when addresses changed afaicr but effectively zero charms are ready to handle that. re public address, unit-get public-address makes it available as info into the charm, but there isn't a mechanism per-se to modify the address or notify wrt to that information. you can manually modify the relation settings that convey private/public address info with juju run ala https://gist.github.com/kapilt/a61efcb4eaef9e685397 might be helpful if you could clarify the context that the public address changed and how its causing a problem with a concrete example.
