-* **Administrator Options**: Administrator options provide user management which can add, change or remove user by an admin user.
-
-
-
-## Install
-
-**System requirements:**
-Board is deployed as several Docker containers, and, therefore, can be deployed on any Linux distribution that supports Docker. The target host requires Python, Docker, and Docker Compose to be installed.
-* Python should be version 2.7 or higher. Note that you may have to install Python on Linux distributions (Gentoo, Arch) that do not come with a Python interpreter installed by default
-* Docker engine should be version 1.11.2 or higher. For installation instructions, please refer to: https://docs.docker.com/engine/installation/
-* Docker Compose needs to be version 1.7.1 or higher. For installation instructions, please refer to: https://docs.docker.com/compose/install/
-
-### Install
-The installation steps boil down to the following
-
-1. Download the installer;
-2. Configure **board.cfg**;
-3. Run **install.sh** to install and start Board;
-Note: If you need prepare Kubernetes and Registry environment, please refer to the appendix part.
-
-
-#### Downloading the installer:
-
-The binary of the installer can be downloaded from the `release` page. Choose either online or offline installer. Use *tar* command to extract the package.
-
-The difference between online installer and offline installer is:
-* The online installation package directly pulls the image from dockerhub, the installer is very small in size.
-* The offline installation package contains all the images needed for this project, so the installation package is quite larger
-
-Online installer:
-```sh
- $ tar xvf board-online-installer-VERSION[-ARCH].tgz
-```
-Offline installer:
-```sh
- $ tar xvf board-offline-installer-VERSION[-ARCH].tgz
-```
-
-#### Configuring Board
-Configuration parameters are located in the file **board.cfg**.
-
-There are two categories of parameters in board.cfg, **required parameters** and **optional parameters**.
-
-* **required parameters**: These parameters are required to be set in the configuration file. They will take effect if a user updates them in ```board.cfg``` and run the ```install.sh``` script to reinstall Board.
-* **optional parameters**: These parameters are optional for updating. Subsequent update to these parameters in ```board.cfg``` will be ignored.
-
-The parameters are described below - note that at the very least, you will need to change the **hostname** attribute.
-
-##### Required parameters:
-
-* **hostname**: The target host's hostname, which is used to access the UI and the apiserver service. It should be the IP address or the fully qualified domain name (FQDN) of your target machine, e.g., `192.168.1.10` or `reg.yourdomain.com`. _Do NOT use `localhost` or `127.0.0.1` for the hostname - the apiserver service needs to be accessible by external clients!_
-* **db_password**: The root password for the MySQL database used for **db_auth**. _Change this password for any production use!_
-
-##### Optional parameters
-
-* **board_admin_password**: The administrator's initial password. This password only takes effect for the first time Board launches. After that, this setting is ignored and the administrator's password should be set in the UI. _Note that the default username/password are **boardadmin/123456a?** ._
-* **auth_mode**: The type of authentication that is used. By default, it is **db_auth**, i.e. the credentials are stored in a database.
- For LDAP authentication, set this to **ldap_auth**.
-
- **IMPORTANT:** When upgrading from an existing Board instance, you must make sure **auth_mode** is the same in ```board.cfg``` before launching the new version of Board. Otherwise, users may not be able to log in after the upgrade.
-* **ldap_url**: The LDAP endpoint URL (e.g. `ldaps://ldap.mydomain.com`). Only used when **auth_mode** is set to *ldap_auth* .
-* **ldap_searchdn**: The DN of a user who has the permission to search an LDAP/AD server (e.g. `uid=admin,ou=people,dc=mydomain,dc=com`).
-* **ldap_search_pwd**: The password of the user specified by *ldap_searchdn*.
-* **ldap_basedn**: The base DN to look up a user, e.g. `ou=people,dc=mydomain,dc=com`. Only used when **auth_mode** is set to *ldap_auth* .
-* **ldap_filter**:The search filter for looking up a user, e.g. `(objectClass=person)`.
-* **ldap_uid**: The attribute used to match a user during a LDAP search, it could be uid, cn, email or other attributes.
-* **ldap_scope**: The scope to search for a user, LDAP_SCOPE_BASE, LDAP_SCOPE_ONELEVEL, LDAP_SCOPE_SUBTREE. Default is LDAP_SCOPE_SUBTREE.
-* **self_registration**: (**on** or **off**. Default is **on**) Enable / Disable the ability for a user to register himself/herself. When disabled, new users can only be created by the Admin user, only an admin user can create new users in Board. _NOTE_: When **auth_mode** is set to **ldap_auth**, self-registration feature is **always** disabled, and this flag is ignored.
-* **token_expiration**: The expiration time (in minutes) of a token created by token service, default is 30 minutes.
-
-#### Connecting Kubernetes cluster which authentication strategy with CA certification
-If the Kubernetes cluster which Board connect to authentication strategy with CA certification, you must copy the Kubernetes cluster's CA files to your machine which installing the Board. You should put CA files into /etc/board/cert directory and name them as 'ca-key.pem'(for private key) and 'ca.pem'(for public key).
-
-You also need to deploy the following two files in your Kubernetes for Board to take over your Kubernetes cluster:
-```sh
-$ mkdir board-k8s-requires
-$ cd board-k8s-requires
-# board-clusterrolebinding.yaml
-$ wget https://raw.githubusercontent.com/inspursoft/board-installer/main/ansible_k8s/roles/kubectlCMD/templates/board-clusterrolebinding.yaml
-$ kubectl apply -f board-clusterrolebinding.yaml
-
-# cadvisor.yaml
-$ wget https://raw.githubusercontent.com/inspursoft/board-installer/main/ansible_k8s/roles/kubectlCMD/templates/cadvisor.yaml
-# You need to replace the {{docker_dir}} placeholder in the file before deploying. The docker directory defaults to /var/lib/docker
-$ kubectl apply -f cadvisor.yaml
-```
-
-In addition, there are some optional features:
-
-**Helm Chart:** The chart museum is integrated in the Board, which depends on helm2
-```sh
-# tiller.yaml
-$ wget https://raw.githubusercontent.com/inspursoft/board-installer/main/ansible_k8s/roles/kubectlCMD/templates/tiller.yaml
-# tiller-service.yaml
-$ wget https://raw.githubusercontent.com/inspursoft/board-installer/main/ansible_k8s/roles/kubectlCMD/templates/tiller-service.yaml
-$ kubectl apply tiller.yaml
-$ kubectl apply tiller-service.yaml
-```
-
-**EFK + Prometheus:** Board supports EFK+Prometheus log management
-```sh
-# fluentd.yaml
-$ wget https://raw.githubusercontent.com/inspursoft/board-installer/main/ansible_k8s/roles/kubectlCMD/templates/fluentd.yaml
-# Need to replace the {{board_ip_address}} {{docker_dir}} placeholder in the file before deploying
-$ kubectl apply -f fluentd.yaml
-
-# prometheus.yaml
-$ wget https://raw.githubusercontent.com/inspursoft/board-installer/main/ansible_k8s/roles/kubectlCMD/templates/prometheus.yaml
-# prometheus2.yaml
-$ wget https://raw.githubusercontent.com/inspursoft/board-installer/main/ansible_k8s/roles/kubectlCMD/templates/prometheus2.yaml
-# Need to replace the {{nfs_dir}} {{nsf_server_ip_address}} placeholder in the file before deploying, or replace this file with your own pv
-$ kubectl apply -f prometheus.yaml
-$ kubectl apply -f prometheus2.yaml
-```
-
-**Note:** If your kubernetes cluster is installed by the [inspursoft/board-installer](https://github.com/inspursoft/board-installer), you do not need to perform the above steps because the project’s automation script have been completed.
-
-Then you should configure these items in **board.cfg**:
-
-* **kube_http_scheme**: Set to 'https'. It means the requests Board send to Kubernetes cluster will be used via 'https' protocol.
-* **kube_master_ip**: The IP address of the Master of Kubernetes cluster.
-* **kube_master_port**: The port number of the Master of Kubernetes cluster(maybe 443 or 6443).
-
-#### Finishing installation and starting Board
-Once **board.cfg** is configured, install and start Board using the ```install.sh``` script.
-
-##### Default installation
-
-```sh
- $ sudo ./install.sh
-```
-
-#### After installation
-If everything worked properly, you should be able to open a browser to visit the admin portal at **http://reg.yourdomain.com** (change *reg.yourdomain.com* to the hostname configured in your ```board.cfg```). Note that the default administrator username/password are boardadmin/123456a? .
-
-Log in to the admin portal and create a new project, e.g. `myproject`. You can create your own service now.
-
-For information on how to use Board, please refer to **[User Guide of Board](docs/user_guide.md)** .
-
-For details on how to download and use the installation package, please refer to [Installation and Configuration Guide](docs/installation_guide.md).
-
-## Upgrade
-
-When upgrading your existing Board instance to a newer version, you may need to migrate the data in your database. Refer to [change log](../tools/migration/changelog.md) to find out whether there is any change in the database. If there is, you should go through the database migration process. Since the migration may alter the database schema, you should **always** backup your data before any migration.
-
-*If your install Board for the first time, or the database version is the same as that of the latest version, you do not need any database migration.*
-
-### Upgrading Board and migrating data
-1 Log in to the host that Board runs on, stop and remove existing Board instance if it is still running:
-
- ```sh
- cd Deploy
- docker-compose down
- ```
-
-2 Backup Board's current files so that you can roll back to the current version when it is neccessary.
-
- ```sh
- cd ..
- mv Deploy /my_backup_dir/Deploy
- mv /data/board /my_backup_dir/board
- ```
-
-3 Get the latest Board release package from github:
-
- ```
- https://github.com/inspursoft/board
- ```
-
-4 Before upgrading Board, perform database migration first. The migration tool is delivered as a Docker image, so you should build it yourself.
-
- ```sh
- git clone https://github.com/inspursoft/board.git
- cd board/tools/migration
- docker build -t board-migration .
- ```
-
-5 You should start you current Board database by handy.
-
- ```sh
- docker run -d -p 3306:3306 -v /data/board/database:/var/lib/mysql -e DB_PASSWORD=root123 dev_db:dev
- ```
-
-6 Backup database to a directory such as `/data/board-migration/backup`. You also need the IP address, port number,username and password to access the database are provided via environment variables "DB_IP", "DB_PORT", "DB_USR", "DB_PWD".
-
- ```sh
- docker run --rm -v /data/board-migration/backup:/board-migration/backup -e DB_IP=10.0.0.0 -e DB_PORT=3306 -e DB_USR=root -e DB_PWD=root123 board-migration backup
- ```
-7 Upgrade database schema and migrate data.
-
- ```sh
- docker run --rm -v /data/board-migration/backup:/board-migration/backup -e DB_IP=10.0.0.0 -e DB_PORT=3306 -e DB_USR=root -e DB_PWD=root board-migration upgrade head
- ```
-
- **NOTE:**
- If you execute this command in a short while after starting the Board database, you may meet errors as the database is not ready for connection. Please retry it after waiting for a while.
-
-### Roll back from an upgrade
-For any reason, if you want to back to the previous version of Board, follow the below steps:
-
-1 Stop and remove the current Board service if it is still running.
-
- ```sh
- cd Deploy
- docker-compose down
- ```
-
-2 Start stand-alone container of Board database
-
- ```sh
- docker run -d -p 3306:3306 -v /data/board/database:/var/lib/mysql -e DB_PASSWORD=root123 dev_db:dev
- ```
-
-3 Restore database from backup file in `/data/board-migration/backup`.
-
- ```sh
- docker run --rm -v /data/board-migration/backup:/board-migration/backup -e DB_IP=10.0.0.0 -e DB_PORT=3306 -e DB_USR=root -e DB_PWD=root123 board-migration restore
- ```
-
-4 You should use the corresponding version of Board to start with it.
-
-### Migration tool reference
-Use `help` command to show instruction of migration tool:
-`data/board-migration/backup`.
-
- ```sh
- docker run --rm -v /data/board-migration/backup:/board-migration/backup -e DB_IP=10.0.0.0 -e DB_PORT=3306 -e DB_USR=root -e DB_PWD=root123 board-migration help
- ```

+
+2 Backup Board's current files so that you can roll back to the current version when it is neccessary.
+
+ ```sh
+ cd ..
+ mv Deploy /my_backup_dir/Deploy
+ mv /data/board /my_backup_dir/board
+ ```
+
+3 Get the latest Board release package from github:
+
+ ```
+ https://github.com/inspursoft/board
+ ```
+
+4 Before upgrading Board, perform database migration first. The migration tool is delivered as a Docker image, so you should build it yourself.
+
+ ```sh
+ git clone https://github.com/inspursoft/board.git
+ cd board/tools/migration
+ docker build -t board-migration .
+ ```
+
+5 You should start you current Board database by handy.
+
+ ```sh
+ docker run -d -p 3306:3306 -v /data/board/database:/var/lib/mysql -e DB_PASSWORD=root123 dev_db:dev
+ ```
+
+6 Backup database to a directory such as `/data/board-migration/backup`. You also need the IP address, port number,username and password to access the database are provided via environment variables "DB_IP", "DB_PORT", "DB_USR", "DB_PWD".
+
+ ```sh
+ docker run --rm -v /data/board-migration/backup:/board-migration/backup -e DB_IP=10.0.0.0 -e DB_PORT=3306 -e DB_USR=root -e DB_PWD=root123 board-migration backup
+ ```
+7 Upgrade database schema and migrate data.
+
+ ```sh
+ docker run --rm -v /data/board-migration/backup:/board-migration/backup -e DB_IP=10.0.0.0 -e DB_PORT=3306 -e DB_USR=root -e DB_PWD=root board-migration upgrade head
+ ```
+
+ **NOTE:**
+ If you execute this command in a short while after starting the Board database, you may meet errors as the database is not ready for connection. Please retry it after waiting for a while.
+
+### Roll back from an upgrade
+For any reason, if you want to back to the previous version of Board, follow the below steps:
+
+1 Stop and remove the current Board service if it is still running.
+
+ ```sh
+ cd Deploy
+ docker-compose down
+ ```
+
+2 Start stand-alone container of Board database
+
+ ```sh
+ docker run -d -p 3306:3306 -v /data/board/database:/var/lib/mysql -e DB_PASSWORD=root123 dev_db:dev
+ ```
+
+3 Restore database from backup file in `/data/board-migration/backup`.
+
+ ```sh
+ docker run --rm -v /data/board-migration/backup:/board-migration/backup -e DB_IP=10.0.0.0 -e DB_PORT=3306 -e DB_USR=root -e DB_PWD=root123 board-migration restore
+ ```
+
+4 You should use the corresponding version of Board to start with it.
+
+### Migration tool reference
+Use `help` command to show instruction of migration tool:
+`data/board-migration/backup`.
+
+ ```sh
+ docker run --rm -v /data/board-migration/backup:/board-migration/backup -e DB_IP=10.0.0.0 -e DB_PORT=3306 -e DB_USR=root -e DB_PWD=root123 board-migration help
+ ```

+## Quick start with kind
+
+About `kind` :
+
+> kind is a tool for running local Kubernetes clusters using Docker container “nodes”.
+> kind was primarily designed for testing Kubernetes itself, but may be used for local development or CI.
+
+Install `kind` : https://kind.sigs.k8s.io/docs/user/quick-start/
+
+Quick start Board with kind:
+
+``` BASH
+# prepare a three nodes cluster
+$ cat > kind-config.yaml << EOF
+# three node (two workers) cluster config
+kind: Cluster
+apiVersion: kind.x-k8s.io/v1alpha4
