kustomize方式安装

前置条件

安装Kustomize v3+

go get sigs.k8s.io/kustomize/kustomize/v3@v3.8.7
~/go/bin/kustomize version

下载MogDB Operator样例

包含了MogDB Operator Kustomize安装器。

https://cdn-mogdb.enmotech.com/mogdb-stack/v1.0.0/mogdb-operator-examples.tar
```
wget https://cdn-mogdb.enmotech.com/mogdb-stack/v1.0.0/mogdb-operator-examples.tar
tar xf mogdb-operator-examples.tar
cd mogdb-operator-examples
```
MogDB Operator安装项目在kustomize/install目录下。
安装的组件
- mogdb-operator-controller-manager
- mogdb-apiserver
- mgo-client
  
  其中，mgo-client运行在物理机下，其余组件都运行在k8s下
生成的k8s对象
- mogdb-operator-manager-config
- mogdb-operator-mgo-config
- mogdb-operator-huawei-registry

配置

默认的Kustomize可以工作在大部分Kubernetes环境中，也可以根据您的特殊需求定制。

例如，为MogDB Operator自定义镜像路径，该镜像在kustomize/install/default/kustomization.yaml文件中，可以修改为:

images:
- name: controller
  newName: swr.cn-north-4.myhuaweicloud.com/mogdb-cloud/mogdb-operator
  newTag: v1.0.0

如果需要更改namespace名称，需要在kustomize/install/default/kustomization.yaml文件中修改如下配置。

namespace: custom-namespace

安装

安装 MogDB Operator

kustomize build ./kustomize/install/default | kubectl apply -f -

期望输出:

安装 mgo 客户端

wget https://cdn-mogdb.enmotech.com/mogdb-stack/v1.0.0/client-setup.sh
chmod +x client-setup.sh
./client-setup.sh

这将下载mgo客户端并且提示您添加一些环境变量以供您在会话中设置，您可以使用以下命令执行此操作：

export MGOUSER="${HOME?}/.mgo/mgouser"
export MGO_CA_CERT="${HOME?}/.mgo/client.crt"
export MGO_CLIENT_CERT="${HOME?}/.mgo/client.crt"
export MGO_CLIENT_KEY="${HOME?}/.mgo/client.key"
export MGO_APISERVER_URL='https://127.0.0.1:32444'
export MGO_NAMESPACE=mogdb-operator-system

如果您希望将这些变量永久添加到您的环境中，您可以运行以下命令：

cat <<EOF >> ~/.bashrc
export PATH="${HOME?}/.mgo:$PATH"
export MGOUSER="${HOME?}/.mgo/mgouser"
export MGO_CA_CERT="${HOME?}/.mgo/client.crt"
export MGO_CLIENT_CERT="${HOME?}/.mgo/client.crt"
export MGO_CLIENT_KEY="${HOME?}/.mgo/client.key"
export MGO_APISERVER_URL='https://127.0.0.1:32444'
export MGO_NAMESPACE=mogdb-operator-system
EOF

source ~/.bashrc

注意： 对于 macOS 用户，您使用文件是~/.bash_profile而不是~/.bashrc。

卸载

kustomize build config/default | kubectl delete -f -

期望输出:

namespace "mogdb-operator-system" deleted
customresourcedefinition.apiextensions.k8s.io "mogdbbackups.mogdb.enmotech.io" deleted
customresourcedefinition.apiextensions.k8s.io "mogdbclusters.mogdb.enmotech.io" deleted
customresourcedefinition.apiextensions.k8s.io "mogdbrecoveries.mogdb.enmotech.io" deleted
serviceaccount "mogdb-operator-controller-manager" deleted
role.rbac.authorization.k8s.io "mogdb-operator-leader-election-role" deleted

configmap "mogdb-operator-manager-config" deleted
secret "mogdb-operator-huawei-registry" deleted

注意:

卸载之前，请确保系统所有的集群已经删除完整，否则无法卸载。
