# Project Syn: Lieutenant API
Rest API to provide services like inventory, cluster registry, tenant management and
GitOps helper.
**Please note that this project is in it's early stages and under active development**.
This repository is part of Project Syn.
For documentation on Project Syn and this component, see https://syn.tools.
## Documentation
Documentation for this component is written using [Asciidoc][asciidoc] and [Antora][antora].
It is located in the [docs/](docs) folder.
The [Divio documentation structure](https://documentation.divio.com/) is used to organize its content.
You can preview the documentation using the `make antora` command, and then opening a browser to http://localhost:2020.
## OpenAPI Spec
The API is specified in [OpenAPI 3](https://swagger.io/docs/specification/about/) format.
It's available in the file [openapi.yaml](openapi.yaml) in the root folder of this project.
## Run API locally
To run the API on your local workstation, follow these steps:
```
export KUBECONFIG=~/.kube/myconfig
export NAMESPACE=syn-lieutenant
make run
```
The `kubeconfig` must grant access to the cluster.
Check with `curl localhost:8080/healthz` if the API is responding.
## Example queries
Done with [HTTPie](https://httpie.org/), but also works with plain `curl`.
_Create Tenant_
```
http localhost:8080/tenants Authorization:"Bearer $(kubectl get secrets test-token-zzzzz -o json | jq ".data.token" -r | base64 --decode)" displayName="Syn Corp"
```
_Query Tenants_
```
http localhost:8080/tenants Authorization:"Bearer $(kubectl get secrets test-token-zzzzz -o json | jq ".data.token" -r | base64 --decode)"
```
* `test-token-zzzzz` is the token of a ServiceAccount with all the needed RBAC
rights on the underlying Kubernetes cluster
## Development
### API Versioning
There is no API versioning exposed. Internally the "API Evolution" approach is
used which is described in this excellent blog post:
[API Versioning Has No "Right Way"](https://apisyouwonthate.com/blog/api-versioning-has-no-right-way).
### API Mocking
To test the API before writing actual code, API mocking can be used. One cool tool
to do that is [Prism](https://github.com/stoplightio/prism). Example:
```
docker run --init --rm -p 4010:4010 -v $(pwd):/tmp stoplight/prism:3 mock -h 0.0.0.0 "/tmp/openapi.yaml"
curl http://localhost:4010/tenants
```
### Code Generation
As the API spec is written with OpenAPI, the [OpenAPI Generator](https://openapi-generator.tech/) is used to generate the Go boilerplate code.
### Object Name Generation
Some API endpoints store data in Kubernetes objects. These objects must be
named like this:
`pwgen -A -B 6 1`
### Links
