The dependsOn resource option creates a list of explicit dependencies between resources.

Pulumi automatically tracks dependencies between resources when you supply an input argument that came from another resource’s output properties. In some cases, however, you may need to explicitly specify additional dependencies that Pulumi doesn’t know about but must still respect. This might happen if a dependency is external to the infrastructure itself—such as an application dependency—or is implied due to an ordering or eventual consistency requirement. The dependsOn option ensures that resource creation, update, and deletion operations are executed in the correct order.

This example demonstrates how to make res2 dependent on res1, even if there is no property-level dependency:

{{< chooser language "javascript,typescript,python,go,csharp,java,yaml" >}}

{{% choosable language javascript %}}

let res1 = new MyResource("res1", {/*...*/});
let res2 = new MyResource("res2", {/*...*/}, { dependsOn: [res1] });

{{% /choosable %}} {{% choosable language typescript %}}

let res1 = new MyResource("res1", {/*...*/});
let res2 = new MyResource("res2", {/*...*/}, { dependsOn: [res1] });

{{% /choosable %}} {{% choosable language python %}}

res1 = MyResource("res1")
res2 = MyResource("res2", opts=ResourceOptions(depends_on=[res1]))

{{% /choosable %}} {{% choosable language go %}}

res1, _ := NewMyResource(ctx, "res1", &MyResourceArgs{/*...*/})
res2, _ := NewMyResource(ctx, "res2", &MyResourceArgs{/*...*/}, pulumi.DependsOn([]pulumi.Resource{res1}))

{{% /choosable %}} {{% choosable language csharp %}}

var res1 = new MyResource("res1", new MyResourceArgs());
var res2 = new MyResource("res2", new MyResourceArgs(),
    new CustomResourceOptions { DependsOn = { res1 } });

{{% /choosable %}} {{% choosable language java %}}

var res1 = new MyResource("res1", new MyResourceArgs());
var res2 = new MyResource("res2",
    new MyResourceArgs(),
    CustomResourceOptions.builder()
        .dependsOn(res1)
        .build());

{{% /choosable %}} {{% choosable language yaml %}}

resources:
  res1:
    type: MyResource
  res2:
    type: MyResource
    options:
      dependsOn:
        - ${res1}
