kubectl apply -f ${cluster_name} -n ${namespace}
```

如果服务器没有外网，需要在有外网的机器上将 TiDB 集群用到的 Docker 镜像下载下来并上传到服务器上，然后使用 `docker load` 将 Docker 镜像安装到服务器上。

部署一套 TiDB 集群会用到下面这些 Docker 镜像（假设 TiDB 集群的版本是 v4.0.0）：

```shell
pingcap/pd:v4.0.0
pingcap/tikv:v4.0.0
pingcap/tidb:v4.0.0
pingcap/tidb-binlog:v4.0.0
pingcap/ticdc:v4.0.0
pingcap/tiflash:v4.0.0
pingcap/tidb-monitor-reloader:v1.0.1
pingcap/tidb-monitor-initializer:v4.0.0
grafana/grafana:6.0.1
prom/prometheus:v2.18.1
busybox:1.26.2
```

接下来通过下面的命令将所有这些镜像下载下来：

{{< copyable "shell-regular" >}}

```shell
docker pull pingcap/pd:v4.0.0
docker pull pingcap/tikv:v4.0.0
docker pull pingcap/tidb:v4.0.0
docker pull pingcap/tidb-binlog:v4.0.0

docker pull pingcap/tiflash:v4.0.0
docker pull pingcap/tidb-monitor-reloader:v1.0.1
docker pull pingcap/tidb-monitor-initializer:v4.0.0
docker pull grafana/grafana:6.0.1
docker pull prom/prometheus:v2.18.1
docker pull busybox:1.26.2
docker save -o pd-v4.0.0.tar pingcap/pd:v4.0.0
docker save -o tikv-v4.0.0.tar pingcap/tikv:v4.0.0

docker save -o tidb-monitor-initializer-v4.0.0.tar pingcap/tidb-monitor-initializer:v4.0.0

docker save -o prometheus-v2.18.1.tar prom/prometheus:v2.18.1
docker save -o busybox-1.26.2.tar busybox:1.26.2
```

接下来将这些 Docker 镜像上传到服务器上，并执行 `docker load` 将这些 Docker 镜像安装到服务器上：

{{< copyable "shell-regular" >}}

```shell
docker load -i pd-v4.0.0.tar
docker load -i tikv-v4.0.0.tar
docker load -i tidb-v4.0.0.tar
docker load -i tidb-binlog-v4.0.0.tar
docker load -i ticdc-v4.0.0.tar
docker load -i tiflash-v4.0.0.tar
docker load -i tidb-monitor-reloader-v1.0.1.tar

docker load -i grafana-6.0.1.tar
docker load -i prometheus-v2.18.1.tar
docker load -i busybox-1.26.2.tar
```

以上命令会自动创建一个初始化的 Job，该 Job 会尝试利用提供的 secret 给 root 账号创建初始密码，并且创建其它账号和密码（如果指定了的话）。初始化完成后 Pod 状态会变成 Completed，之后通过 MySQL 客户端登录时需要指定这里设置的密码。

如果服务器没有外网，需要在有外网的机器上将集群初始化用到的 Docker 镜像下载下来并上传到服务器上，然后使用 `docker load` 将 Docker 镜像安装到服务器上。

初始化一套 TiDB 集群会用到下面这些 Docker 镜像：

{{< copyable "shell-regular" >}}

```shell
tnir/mysqlclient:latest
```

接下来通过下面的命令将所有这些镜像下载下来：

{{< copyable "shell-regular" >}}

```shell
docker pull tnir/mysqlclient:latest
docker save -o mysqlclient-latest.tar tnir/mysqlclient:latest
```

接下来将这些 Docker 镜像上传到服务器上，并执行 `docker load` 将这些 Docker 镜像安装到服务器上：

{{< copyable "shell-regular" >}}

```shell
docker load -i mysqlclient-latest.tar
