Usage

Describes how to use K2HDKC DBaaS on kubernetes CLI (Command Line Interface).
K2HDKC DBaaS on kubernetes CLI works with kubernetes and K2HR3 systems.

K2HDKC DBaaS on kubernetes CLI works as a plug-in for K2HR3 CLI.

The K2HR3 system is required to build and operate a K2HDKC cluster with K2HDKC DBaaS on kubernetes CLI.
This K2HR3 system should be built within a kubernetes cluster.
K2HDKC DBaaS on kubernetes CLI can also build and delete K2HR3 systems.

The operations such as building the K2HR3 system and creating and deleting the K2HDKC cluster are explained below.

In the following command example, minikube created a local kubernetes cluster and ran K2HDKC DBaaS on kubernetes CLI on that kubernetes cluster. For easy trials, you can install minikube and use K2HDKC DBaaS on kubernetes CLI with it.

Preparing the K2HDKC DBaaS on kubernetes CLI

Construction of K2HR3 system

Learn how to build a K2HR3 system that will be used to build a K2HDKC cluster on kubernetes.
Build this K2HR3 system in the same kubernetes cluster that you build the K2HDKC DBaaS.

Even if you build multiple K2HDKC clusters within a kubernetes cluster, it will work on one K2HR3 system.
That is, one K2HR3 system is sufficient for one kubernetes cluster.
(There is no problem even if you build multiple K2HR3 systems.)

At this time, if you build a K2HDKC cluster using K2HDKC DBaaS on kubernetes CLI, the kubernetes authentication system only supports OpenID Connect.

K2HR3 An example of building a system is shown below.

Succeed : Succeed starting the K2HR3 system

To build the K2HR3 system, run the k2hr3 database-k8s k2hr3 create command.
After this command is executed successfully, access the Endpoint of the K2HR3 APP URL displayed in the execution result with a browser.
You can see the K2HR3 APP(Web Appication).

Describes the options specified in the above example.
Since the K2HR3 system uses the same OpenID Connect as the kubernetes cluster, please prepare the OpenID Connect settings and information in advance.

–k8s_namespace

Specifies the NameSpace to use in the kubernetes cluster.
If omitted, use default.

–k8s_domain

Specifies the Domain name to use in the kubernetes cluster.
If omitted, use svc.cluster.local.

–oidc_client_secret

Specify the Secret of OpenID Connect used by the K2HR3 system.

–oidc_client_id

Specify the Client id of OpenID Connect used by the K2HR3 system.

–oidc_issuer_url

Specify the Issuer URL of OpenID Connect used by the K2HR3 system.

–oidc_username_key

If the token returned by OpenID Connect used by the K2HR3 system has a key indicating the user name, specify that key name.
This option does not need to be specified if the user name key does not exist.

–oidc_cookiename

Specifies the cookie name used to pass the OpenID Connect token used by the K2HR3 system to K2HR3 APP(Web Appication).

Specify this option if you want to specify the port number instead of setting it automatically.

–k2hr3app_nodeport_num

Specifies the port number used by the K2HR3 APP(Web Appication) on the K2HR3 system.
By default, the K2HR3 system is built with NodePort, and the port number used by the K2HR3 APP(Web Appication) is set automatically.
Specify this option if you want to specify the port number instead of setting it automatically.
This option should be specified as the port number must be specified instead of automatically, because this port number is used in a part of URL redirected from OpenID Connect.

–nodehost_ips <ip,ip…>

Set the IP address of each Node in the kubernetes cluster.
These values are used when creating the K2HR3 system self-signed certificate.
If you do not use a self-signed certificate, or if you use minikube, you do not need to specify it.
