|
|
|
|
Generates a kubernetes deployment out of c4k inputs. Can be combined with Terraform- & ProvsK3s-Builds.
|
|
|
|
```mermaid
|
|
classDiagram
|
|
class C4kBuild {
|
|
def update_runtime_config(dns_record) - updates informations after terraform apply
|
|
def write_c4k_config() - provide the configuration for c4k
|
|
def write_c4k_auth() - provide the auth for c4k
|
|
c4k_apply(dry_run=False) - genereates the kubernetes manifest
|
|
}
|
|
```
|
