为什么 pulumi kubernetes 提供商要更改服务和部署名称?
why pulumi kubernetes provider is changing the service and deployment name?

有了这个 pulumi up -y
就成功了,没有错误,但是应用程序还没有完全启动并且 运行。因为 adminer
图像试图将 Postgres 数据库主机名用作 db
,但看起来 pulumi 正在更改服务名称,如下所示:
我的问题是,如何让它可行?
pulumi有没有严格命名的方法?
注意 - 我知道我们可以轻松地将主机名作为环境变量传递给 adminer
图像,但我想知道是否有什么可以让我们不更改名称。
Pulumi 会自动将随机字符串添加到您的资源中,以帮助替换资源。您可以在 FAQ
中找到更多相关信息
如果您想禁用它,您可以使用 metadata
覆盖它,如下所示:
import * as k8s from "@pulumi/kubernetes";
import * as kx from "@pulumi/kubernetesx";
//db
const dbLabels = { app: "db" };
const dbDeployment = new k8s.apps.v1.Deployment("db", {
spec: {
selector: { matchLabels: dbLabels },
replicas: 1,
template: {
metadata: { labels: dbLabels },
spec: {
containers: [
{
name: "postgres",
image: "postgres",
env: [{ name: "POSTGRES_USER", value: "postgres"},{ name: "POSTGRES_PASSWORD", value: "postgres"}],
ports: [{containerPort: 5432}]
}
]
}
}
}
});
const dbService = new k8s.core.v1.Service("db", {
metadata: {
name: "db", // explicitly set a name on the service
labels: dbDeployment.spec.template.metadata.labels
},
spec: {
selector: dbLabels,
type: "ClusterIP",
ports: [{ port: 5432, targetPort: 5432, protocol: "TCP" }],
}
});
话虽如此,像这样对名称进行硬编码并不总是最佳做法,如果可能的话,您应该引用资源的输出并将它们传递给新资源。
