## Configuration
|
|
|
|
Currently **Kamaji** supports (in this order):
|
|
|
|
* CLI flags
|
|
* Environment variables
|
|
* Configuration files
|
|
|
|
By default **Kamaji** search for the configuration file (`kamaji.yaml`) and uses parameters found inside of it. In case some environment variable are passed, this will override configuration file parameters. In the end, if also a CLI flag is passed, this will override both env vars and config file as well.
|
|
|
|
This is easily explained in this way:
|
|
|
|
`cli-flags` > `env-vars` > `config-files`
|
|
|
|
Available flags are the following:
|
|
|
|
```
|
|
--config-file string Configuration file alternative. (default "kamaji.yaml")
|
|
--datastore string The default DataStore that should be used by Kamaji to setup the required storage (default "etcd")
|
|
--health-probe-bind-address string The address the probe endpoint binds to. (default ":8081")
|
|
--kine-image string Container image along with tag to use for the Kine sidecar container (used only if etcd-storage-type is set to one of kine strategies) (default "rancher/kine:v0.9.2-amd64")
|
|
--kubeconfig string Paths to a kubeconfig. Only required if out-of-cluster.
|
|
--leader-elect Enable leader election for controller manager. Enabling this will ensure there is only one active controller manager.
|
|
--metrics-bind-address string The address the metric endpoint binds to. (default ":8080")
|
|
--tmp-directory string Directory which will be used to work with temporary files. (default "/tmp/kamaji")
|
|
--zap-devel Development Mode defaults(encoder=consoleEncoder,logLevel=Debug,stackTraceLevel=Warn). Production Mode defaults(encoder=jsonEncoder,logLevel=Info,stackTraceLevel=Error) (default true)
|
|
--zap-encoder encoder Zap log encoding (one of 'json' or 'console')
|
|
--zap-log-level level Zap Level to configure the verbosity of logging. Can be one of 'debug', 'info', 'error', or any integer value > 0 which corresponds to custom debug levels of increasing verbosity
|
|
--zap-stacktrace-level level Zap Level at and above which stacktraces are captured (one of 'info', 'error', 'panic').
|
|
--zap-time-encoding time-encoding Zap time encoding (one of 'epoch', 'millis', 'nano', 'iso8601', 'rfc3339' or 'rfc3339nano'). Defaults to 'epoch'.
|
|
```
|
|
|
|
Available environment variables are:
|
|
|
|
| Environment variable | Description |
|
|
|--------------------------------------|------------------------------------------------------------------------------------------------------------------------|
|
|
| `KAMAJI_DATASTORE` | Name of the DataStore resource with driver definition and settings. (default "etcd") |
|
|
| `KAMAJI_METRICS_BIND_ADDRESS` | The address the metric endpoint binds to. (default ":8080") |
|
|
| `KAMAJI_HEALTH_PROBE_BIND_ADDRESS` | The address the probe endpoint binds to. (default ":8081") |
|
|
| `KAMAJI_LEADER_ELECTION` | Enable leader election for controller manager. Enabling this will ensure there is only one active controller manager. |
|
|
| `KAMAJI_TMP_DIRECTORY` | Directory which will be used to work with temporary files. (default "/tmp/kamaji") |

## Build and deploy
|
|
Clone the repo on your workstation.
|
|
|
|
```bash
|
|
## Install dependencies
|
|
$ go mod tidy
|
|
|
|
## Generate code
|
|
$ make generate
|
|
|
|
## Generate Manifests
|
|
$ make manifests
|
|
|
|
## Install Manifests
|
|
$ make install
|
|
|
|
## Build Docker Image
|
|
$ IMG=<image name and tag> make docker-build
|
|
|
|
## Push Docker Image
|
|
$ IMG=<image name and tag> make docker-push
|
|
|
|
## Deploy Kamaji
|
|
$ IMG=<image name and tag> make deploy
|
|
|
|
## YAML Installation File
|
|
$ make yaml-installation-file
|
|
|
|
```
|
|
|
|
It will generate a yaml installation file at `config/install.yaml`. It should be customize accordingly.
|
|
|
|
## Tenant Control Planes
|
|
|
|
**Kamaji** offers a [CRD](https://kubernetes.io/docs/tasks/extend-kubernetes/custom-resources/custom-resource-definitions/) to provide a declarative approach of managing tenant control planes. This *CRD* is called `TenantControlPlane`, or `tcp` in short. Use the command `kubectl explain tcp.spec` to understand the fields and their usage.
|
|
|
|
### Add-ons
|
|
|
|
**Kamaji** provides optional installations into the deployed tenant control plane through add-ons. Is it possible to enable/disable them through the `tcp` definition.
