Since this plan leverages BGP for K8s Control Plane load balancing, a router capable of BGP is required. For lab/dev/test use, a small single-CPU Linux VM running [BIRD v2 daemon](https://bird.network.cz/?get_doc&f=bird.html&v=20) (`sudo apt install bird2`) with the following config would suffice: 23 | 24 | ```bash 25 | protocol bgp kubevip { 26 | description "kube-vip for Cluster CP"; 27 | local as 64513; 28 | neighbor range as ; 29 | graceful restart; 30 | ipv4 { 31 | import filter {accept;}; 32 | export filter {reject;}; 33 | }; 34 | dynamic name "kubeVIP"; 35 | } 36 | ``` 37 | 38 | ## Caveats 39 | 40 | The `cluster_autoscaler.tf` plan includes the following values in `ExtraArgs:` 41 | 42 | ```terraform 43 | skip-nodes-with-local-storage: false 44 | skip-nodes-with-system-pods: false 45 | ``` 46 | 47 | Those exist here to make the autoscaler logic more easily demonstrable and should be **_used with caution_** in production or any other environment you care about, as they could incur data loss or workload instability. 48 | 49 | --- 50 | 51 | The `lifecycle` block in `cluster.tf` is somewhat fragile: 52 | 53 | ```terraform 54 | lifecycle { 55 | ignore_changes = [ 56 | rke_config[0].machine_pools[1].quantity 57 | ] 58 | } 59 | ``` 60 | 61 | Starting from the [0] value, Terraform processes indices lexicographically - the "worker" pool is `machine_pools[1]` and "ctl_plane" pool is `machine_pools[0]` for no other reason than "worker" comes after "ctl_plane" from a dictionary perspective. Due to this, if the "ctl_plane" pool were to be renamed something like "x_ctl_plane", the incorrect machine pool would occupy the `machine_pools[1]` index, causing undesired behavior. To prevent this, basic variable validation is in place that forces MachinePool names to begin with `ctl-plane` and `worker` otherwise the below error will be thrown: 62 | 63 | ```bash 64 | Err: MachinePool names must begin with 'ctl-plane' for Control Plane Node Pool & 'worker' for Autoscaling Worker Node 65 | Pool. 66 | ``` 67 | 68 | ## To Run 69 | 70 | ```bash 71 | terraform apply 72 | ``` 73 | 74 | Node pool min/max values are annotations that can be adjusted with the `rancher_env.autoscale_annotations` variable. Changing these values on a live cluster will not trigger a redeploy. Any nodes in the autoscaled pool selected for scale down and/or deletion will have a Taint applied that is visible in the Rancher UI: 75 | 76 | ![autoscaler](https://user-images.githubusercontent.com/88675306/189248687-4b949567-ebd0-460e-a42e-d13dc1706410.png) 77 | 78 | ## Tested Versions 79 | 80 | | SOFTWARE | VERSION | DOCS | 81 | |:---------|:--------|:-----| 82 | | K8s Cluster Autoscaler | 1.26.2 | | 83 | | kube-vip | 0.6.2 | | 84 | | Rancher Server | 2.7.6 | | 85 | | Rancher Terraform Provider | 3.1.1 | | 86 | | RKE2 | 1.26.8+rke2r1 | | 87 | | Terraform | 1.4.6 | | 88 | | vSphere | 8.0.1.00300 | | 89 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | Mozilla Public License Version 2.0 2 | ================================== 3 | 4 | 1.

Distribution of Source Form 161 | 162 | All distribution of Covered Software in Source Code Form, including any 163 | Modifications that You create or to which You contribute, must be under 164 | the terms of this License.

Distribution of a Larger Work 186 | 187 | You may create and distribute a Larger Work under terms of Your choice, 188 | provided that You also comply with the requirements of this License for 189 | the Covered Software. If the Larger Work is a combination of Covered 190 | Software with a work governed by one or more Secondary Licenses, and the 191 | Covered Software is not Incompatible With Secondary Licenses, this 192 | License permits You to additionally distribute such Covered Software 193 | under the terms of such Secondary License(s), so that the recipient of 194 | the Larger Work may, at their option, further distribute the Covered 195 | Software under the terms of either this License or such Secondary 196 | License(s). 197 | 198 | 3.4. Notices 199 | 200 | You may not remove or alter the substance of any license notices 201 | (including copyright notices, patent notices, disclaimers of warranty, 202 | or limitations of liability) contained within the Source Code Form of 203 | the Covered Software, except that You may alter any license notices to 204 | the extent required to remedy known factual inaccuracies. 205 | 206 | 3.5. Application of Additional Terms 207 | 208 | You may choose to offer, and to charge a fee for, warranty, support, 209 | indemnity or liability obligations to one or more recipients of Covered 210 | Software.

Termination 233 | -------------- 234 | 235 | 5.1. The rights granted under this License will terminate automatically 236 | if You fail to comply with any of its terms. However, if You become 237 | compliant, then the rights granted under this License from a particular 238 | Contributor are reinstated (a) provisionally, unless and until such 239 | Contributor explicitly and finally terminates Your grants, and (b) on an 240 | ongoing basis, if such Contributor fails to notify You of the 241 | non-compliance by some reasonable means prior to 60 days after You have 242 | come back into compliance. Moreover, Your grants from a particular 243 | Contributor are reinstated on an ongoing basis if such Contributor 244 | notifies You of the non-compliance by some reasonable means, this is the 245 | first time You have received notice of non-compliance with this License 246 | from such Contributor, and You become compliant prior to 30 days after 247 | Your receipt of the notice. 248 | 249 | 5.2. If You initiate litigation against any entity by asserting a patent 250 | infringement claim (excluding declaratory judgment actions, 251 | counter-claims, and cross-claims) alleging that a Contributor Version 252 | directly or indirectly infringes any patent, then the rights granted to 253 | You by any and all Contributors for the Covered Software under Section 254 | 2.1 of this License shall terminate. 255 | 256 | 5.3. In the event of termination under Sections 5.1 or 5.2 above, all 257 | end user license agreements (excluding distributors and resellers) which 258 | have been validly granted by You or Your distributors under this License 259 | prior to termination shall survive termination. 260 | 261 | ************************************************************************ 262 | * * 263 | * 6.
