# Kubernetes
|
||
|
||
你可以使用 Kubernetes 来托管你的 Atuin 服务器。
|
||
|
||
为数据库凭证创建 [`secrets.yaml`](../../k8s/secrets.yaml) 文件：
|
||
|
||
```yaml
|
||
apiVersion: v1
|
||
kind: Secret
|
||
metadata:
|
||
name: atuin-secrets
|
||
type: Opaque
|
||
stringData:
|
||
ATUIN_DB_USERNAME: atuin
|
||
ATUIN_DB_PASSWORD: seriously-insecure
|
||
ATUIN_HOST: "127.0.0.1"
|
||
ATUIN_PORT: "8888"
|
||
ATUIN_OPEN_REGISTRATION: "true"
|
||
ATUIN_DB_URI: "postgres://atuin:seriously-insecure@localhost/atuin"
|
||
immutable: true
|
||
```
|
||
|
||
为 Atuin 服务器创建 [`atuin.yaml`](../../k8s/atuin.yaml) 文件：
|
||
|
||
|
||
```yaml

|
||

|

|
||
```
|
||
|
||
最后，你可能想让 atuin 使用单独的命名空间（namespace），创建 [`namespace.yaml`](../../k8s/namespaces.yaml) 文件：
|
||
|
||
```yaml
|
||
apiVersion: v1
|
||
kind: Namespace
|
||
metadata:
|
||
name: atuin-namespace
|
||
labels:
|
||
name: atuin
|
||
```
|
||
|
||
在企业级安装部署时，你可能想要数据库内容永久存储在集群中，而不是在主机系统中。在上述配置中，`storageClassName` 配置为 `manual`，主机系统的挂载目录配置为 `/Users/firstname.lastname/.kube/database`，请注意，这些配置将会使得数据库内容存储在 kubernetes 集群<i>外部</i>中。
|
||
|
||
你还应该将 `secrets.yaml` 文件中的 `ATUIN_DB_PASSWORD` 和 `ATUIN_DB_URI` 修改为更安全的加密字符串。
|
||
|
||
Atuin 运行在主机系统的 `30530` 端口上。这是通过 `nodePort` 属性进行陪你的。Kubernetes 有一个严格规则，即不允许暴露小于 30000 的端口号。为了使客户端能够正常工作，你需要在你的 `config.toml` 文件中设置端口号，例如 `sync_address = "http://192.168.1.10:30530"`。
|
||
|
||
使用 `kubectl` 部署 Atuin 服务器：
|
||
|
||
```shell
|
||
kubectl apply -f ./namespaces.yaml
|
||
kubectl apply -n atuin-namespace \
|
||
-f ./secrets.yaml \
|
||
-f ./atuin.yaml
|
||
```
|
||
|
||
上面示例同时也位于 atuin 仓库（repository）的 [k8s](../../k8s) 目录下。
