读取局部州/检查点值Pulumi

Question

TL；DR..I希望在保存本地Pulumi堆栈的情况下，在较新的堆栈中准备好以前堆栈的输出。例如，在以前创建的VPC/子网中创建AWS Fargate ECS集群。如何在Python中做到这一点？

我创建了dev Pulumi堆栈，应用代码：

$ mkdir pulumi-infra-az
$ pulumi login --local
$ pulumi stack init dev

得到了这样的Outputs

...
Outputs:
    pulumi-private-subnet-ids: [
        [0]: "subnet-0dcbaabe273db8feb"
        [1]: "subnet-08c63207611c6bae2"
        [2]: "subnet-00fa346a71a323551"
    ]
    pulumi-public-subnet-ids : [
        [0]: "subnet-02c50846690f2cd70"
        [1]: "subnet-06282506863db7ac1"
        [2]: "subnet-0cfae8a4f5e4fc03c"
    ]
    pulumi-vpc-id            : "vpc-0767f0d49e3a59d42"

    22 unchanged

正如您在这里看到的，我使用的是本地堆栈放置/root/.pulumi/stacks/dev.json。到目前一切尚好。现在，在其他dir中，我想创建fargate集群描述：

$ mkdir pulumi-ecs-fargate
$ pulumi stack init dev-ecs # by the way can I use the same `dev` stack name here?

这里我需要阅读以前创建的pulumi-private-subnet-ids、pulumi-public-subnet-ids、pulumi-vpc-id输出值吗？怎样才能做到正确呢？

我只找到了https://app.pulumi.com后端示例：

https://www.pulumi.com/docs/intro/concepts/organizing-stacks-projects/#inter-stack-dependencies

https://www.pulumi.com/docs/intro/concepts/programming-model/#stack-references

https://www.pulumi.com/docs/tutorials/aws/aws-py-stackreference/

谁能提供本地或AWS s3示例，如何在其他堆栈/dir中读取输出？

Answer 1

好的，读取本地状态输出也是可能的。登录并创建第一个堆栈：

$ pulumi logout
$ pulumi login --local

$ mkdrir pulumi-infra-az
$ cd pulumi-infra-az

$ pulumi stack init pulumi-infra-az-dev

应用它：

$ pulumi up

...
Outputs:
    pulumi-private-subnet-ids: [
        [0]: "subnet-0e8eb4cd276720a51"
        [1]: "subnet-0447d96727f6fdf62"
        [2]: "subnet-02e0e1d44183f7733"
    ]
    pulumi-public-subnet-ids : [
        [0]: "subnet-00b1c052633b93f73"
        [1]: "subnet-0333dd2abc409acb7"
        [2]: "subnet-006e949371228f8bd"
    ]
    pulumi-vpc-id            : "vpc-0e59fc2d7df06bac0"

Resources:
    + 25 created
...

现在创建新的dir和堆栈：

$ mkdir pulumi-ecs-fargate
$ cd pulumi-ecs-fargate

$ pulumi stack init pulumi-ecs-fargate-dev

堆叠的名称应该不同。而不是读到新的产出：

...
# Reading local state
infra = pulumi.StackReference(f"pulumi-infra-az-dev")

# Read back the default VPC and public subnets, which we will use.
pulumi_vpc = infra.get_output("pulumi-vpc-id")
pulumi_private_subnets = infra.get_output("pulumi-private-subnet-ids")
pulumi_public_subnets = infra.get_output("pulumi-public-subnet-ids")
...

很遗憾普利米没有很好的手册/例子。
