读取本地 state/checkpoint 值 Pulumi

Question

TL;DR. 我想在本地 Pulumi 堆栈保存的新堆栈中准备好先前堆栈的输出。例如在之前创建的 VPC/Subnets 中创建一个 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"

如您所见，我正在使用本地堆栈放置 /root/.pulumi/stacks/dev.json。到目前为止，一切都很好。现在在其他目录中我想创建 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?

而这里我需要读取之前创建的 pulumi-private-subnet-ids、pulumi-public-subnet-ids、pulumi-vpc-id 输出值？怎么做正确？

我只找到 https://app.pulumi.com 个后端示例：
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/

任何人都可以提供本地或 AWS s3 示例如何读取其他 stack/dir 中的输出吗？

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
...

现在创建新目录和堆栈：

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

$ pulumi stack init pulumi-ecs-fargate-dev

堆栈名称应该不同。而不是在新的中读取输出：

...
# 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 Pulumi 没有好的 manuals/examples。
