* add support for kubernetes service discoveryMax Audron2022-03-124-1/+206
| | | | | | | | | | | | | | | | | | | | | This commit adds support to discover garage instances running in kubernetes. Once enabled by setting `kubernetes_namespace` and `kubernetes_service_name` garage will create a Custom Resources `garagenodes.deuxfleurs.fr` with nodes public key as the resource name. and IP and Port information as spec in the namespace configured by `kubernetes_namespace`. For discovering nodes the resources are filtered with the optionally set `kubernetes_service_name` which sets a label `garage.deuxfleurs.fr/service` on the resources. This allows to separate multiple garage deployments in a single namespace. the `kubernetes_skip_crd` variable allows to disable the creation of the CRD by garage itself. The user must deploy this manually.

* Improve how node roles are assigned in Garagev0.5-beta1Alex Auvolat2021-11-166-213/+674
| | | | | | | | | | | | | | | | | - change the terminology: the network configuration becomes the role table, the configuration of a nodes becomes a node's role - the modification of the role table takes place in two steps: first, changes are staged in a CRDT data structure. Then, once the user is happy with the changes, they can commit them all at once (or revert them). - update documentation - fix tests - implement smarter partition assignation algorithm This patch breaks the format of the network configuration: when migrating, the cluster will be in a state where no roles are assigned. All roles must be re-assigned and commited at once. This migration should not pose an issue.

* Many improvements on ring/replication and its configuration:Alex Auvolat2021-05-282-46/+114
| | | | | | | | | | | | | | | | | | | | - Explicit "replication_mode" configuration parameters that takes either "none", "2" or "3" as values, instead of letting user configure replication factor themselves. These are presets whose corresponding replication/quorum values can be found in replication/mode.rs - Explicit support for single-node and two-node deployments (number of nodes must be at least "replication_mode", with "none" we can have only one node) - Ring is now stored much more compactly with 256*8 + n*32 bytes, instead of 256*32 bytes - Support for gateway-only nodes that do not store data (these nodes still need a metadata_directory to store the list of bucket and keys since those are stored on all nodes; it also technically needs a data_directory to start but it will stay empty unless we have bugs)
