| kjackal | Good morning Juju world! | 07:10 |

| BlackDex | Hello there | 07:46 |
| BlackDex | I have an environment where i have juju in HA using 3 nodes | 07:46 |
| BlackDex | unfortunally i need to remove 2 of those nodes now because of maintenance | 07:47 |
| BlackDex | how can i remove those nodes manually and afterwards just create new ones? | 07:47 |
| BlackDex | can i juse do juju remove-machine on the controller model? | 07:48 |
| kjackal_ | Hi BlackDex, based on this: https://jujucharms.com/docs/2.1/controllers-ha | 07:53 |
| kjackal_ | BlackDex: "The only way to decrease is to create a backup of your environment and then restore the backup to a new environment, which starts with a single controller. You can then increase to the desired number." | 07:54 |
| kjackal_ | BlackDex: never done that | 07:54 |
| BlackDex | kjackal: Well, one controller is still a controller right | 09:14 |
| BlackDex | ill first create a backup, and remove the 2 machines | 09:14 |
| BlackDex | hmm shutting down the 2 nodes prevents me from using `juju` at all | 09:28 |
| BlackDex | thats not really ha then :) | 09:28 |

| kjackal | hello lazyPower | 12:56 |
| kjackal | what's this code language "/buffer 2" | 12:57 |
| kjackal | ? | 12:57 |
| kjackal | lazyPower: ^ | 12:57 |
| lazyPower | lol sorry | 12:58 |
| lazyPower | early morning, weechat buffer switching | 12:58 |

| Zic | hi here | 14:46 |
| Zic | My CDK cluster running fully@AWS cannot manipulate PV as EBS, I saw on GitHub that it's maybe tied to "CLOUD_PROVIDER" var, do you have any documentation about it? | 14:48 |
| lazyPower | Zic: we haven't released cloud integration points yet. We're still in a bare-metal first representation of k8s. Work has been started to enable that in a juju native way, but its still WIP | 14:50 |
| Zic | thanks for the info :) | 14:51 |
| Zic | lazyPower: do you have any recommendation for PersistentVolume @ AWS so? just a manually created EBS ? | 14:51 |
| Zic | (or EFS) | 14:51 |
| lazyPower | Zic: i've been using EFS with great success | 14:52 |
| lazyPower | but its been only via testing, and i use the NFS volume type | 14:52 |
| lazyPower | so ymmv - i haven't done battle-hardened testing here, just exploratory work | 14:52 |
| Zic | lazyPower: is "cloud integration" just control the fact that CDK cluster can auto-create EBS on-demand, or also the fact that K8s can mount EBS volume? | 14:54 |
| Zic | because I just tried to create the EBS manually and mount it | 14:54 |
| Zic | -> found invalid field AWSElasticBlockStore for v1.PersistentVolumeSpec | 14:54 |
| lazyPower | Zic: no, this would be for cloud level integrations. Giving your nodes IAM profiles to request things from the cloud on your behalf | 14:54 |
| lazyPower | ebs volumes, ELB load balancers, et-al | 14:55 |
| Zic | ok so I can normally mount manually-created EBS, I need to find why it did not work :( | 14:55 |
| Zic | I don't need my cluster to auto-create EBS on-demand, I just need the ability to mount them as PersistentVolume :D | 14:57 |
| Zic | lazyPower: so just to be sure, you confirm that I normally can use this https://kubernetes.io/docs/concepts/storage/volumes/#awselasticblockstore, but I need to create EBS volume manually (as it's precised in the link) before? | 15:07 |
| Zic | or mounting EBS is also part of cloud-integration and I need to stick with EFS | 15:08 |
| Zic | (EFS is cool, but not for large micro-access) | 15:08 |
| Zic | an other solution will be to add "--cloud-provider=aws" to /etc/default/kube-apiserver and kube-controller-manager on master side, and to /etc/default/kubelet node-side | 15:19 |
| Zic | but Juju will erase this extra-parameter | 15:19 |

| lazyPower | Zic: you can also place that in the templates in /var/lib/juju/agents/unit-kubernetes-master-#/charm/templates. But note that once you modify those templates you're making a snowflake. | 17:06 |
| lazyPower | Zic: but if you strawman out what you're looking for, and propose it, we can certainly review the contribution and help get it landed. | 17:07 |

| kwmonroe | petevg: cory_fu: curious about the matrix... http://paste.ubuntu.com/24262725/ is my status output for gce and aws. you see the core count for those matrix models? it's as if they deployed with no machine constraints. contrast that with the non-matrix models in the same job. | 19:18 |
| kwmonroe | petevg: cory_fu: i verified that a sample gce matrix unit did in fact have 1 cpu and 2gb ram. that's not in accordance with any of the constraints set in my bundle. | 19:18 |
| petevg | kwmonroe: matrix can spin up additional machines, remember. | 19:18 |
| petevg | kwmonroe: but there might still be stuff missing when translating constraints in python-libjuju. | 19:19 |
| kwmonroe | ok petevg, so this isn't expected for the matrix first-pass (vs chaos), right? as in, i should expect my bundle constraints to be honored by matrix? | 19:20 |
| petevg | That section of the websocket api is kind of broken. (The websocket api doesn't like parsing the plan that it generates.) | 19:20 |
| petevg | kwmonroe: yes. On the first pass, matrix should honor your constraints. | 19:20 |
| kwmonroe | thx petevg.. issue-a-coming :) | 19:21 |
| petevg | kwmonroe: sounds like tons o' fun. | 19:24 |
| ken_ | Very confused. Set up an Openstack cloud, put all my MAAS nodes in a zone, and tried to go HA -- ran into issues deploying nodes, so decided to back out. Now I can't "juju add-unit" anything: "cannot run instance: No available machine matches constraints: zone=default". Re-added all MAAS nodes to default; same issue. Any ideas before I nuke it all? | 20:00 |
| ken_ | Ah. Just noticed a couple hundred of these, too: ERROR juju.state database.go:231 using unknown collection "remoteApplications" | 20:02 |
| === narinder_out is now known as narinder | ||
| ken_ | OK. Rebooting the Juju node still throws some errors, but it *did* result in nodes being deployed. | 20:11 |
| cholcombe | i don't think you can do this yet but can you tell juju to exclude a set of directories when deploying from a local directory? | 22:01 |
| hatch | cholcombe not as of yet | 22:08 |
| cholcombe | hatch: yeah i thought so. that would be really useful | 22:08 |
| hatch | yes very :) | 22:09 |
| hatch | I can't find the bug right now.... | 22:09 |
| hatch | there is/was one | 22:09 |
| cholcombe | oh cool | 22:09 |
| cholcombe | someone else had the same thought :) | 22:09 |
| hatch | cholcombe it might be worth filing another since I'm not able to find it | 22:10 |
| cholcombe | hatch: ok | 22:13 |
