# Google Cloud Pub/Sub Module
|
|
|
|
This module allows managing a single Pub/Sub topic, including multiple subscriptions and IAM bindings at the topic and subscriptions levels.
|
|
|
|
|
|
## Examples
|
|
|
|
### Simple topic with IAM
|
|
|
|
```hcl
|
|
module "pubsub" {
|
|
source = "./modules/pubsub"
|
|
project_id = "my-project"
|
|
name = "my-topic"
|
|
iam = {
|
|
"roles/pubsub.viewer" = ["group:foo@example.com"]
|
|
"roles/pubsub.subscriber" = ["user:user1@example.com"]
|
|
}
|
|
}
|
|
# tftest:modules=1:resources=3
|
|
```
|
|
|
|
### Subscriptions
|
|
|
|
Subscriptions are defined with the `subscriptions` variable, allowing optional configuration of per-subscription defaults. Push subscriptions need extra configuration, shown in the following example.
|
|
|
|
```hcl
|
|
module "pubsub" {
|
|
source = "./modules/pubsub"
|
|
project_id = "my-project"
|
|
name = "my-topic"
|
|
subscriptions = {
|
|
test-pull = null
|
|
test-pull-override = {
|
|
labels = { test = "override" }
|
|
options = {
|
|
ack_deadline_seconds = null
|
|
message_retention_duration = null
|
|
retain_acked_messages = true
|
|
expiration_policy_ttl = null
|
|
}
|
|
}
|
|
}
|
|
}
|
|
# tftest:modules=1:resources=3
|
|
```
|
|
|
|
### Push subscriptions
|
|
|
|
Push subscriptions need extra configuration in the `push_configs` variable.
|
|
|
|
```hcl
|
|
module "pubsub" {
|
|
source = "./modules/pubsub"
|
|
project_id = "my-project"
|
|
name = "my-topic"
|
|
subscriptions = {
|
|
test-push = null
|
|
}
|
|
push_configs = {
|
|
test-push = {
|
|
endpoint = "https://example.com/foo"
|
|
attributes = null
|
|
oidc_token = null
|
|
}
|
|
}
|
|
}
|
|
# tftest:modules=1:resources=2
|
|
```
|
|
|
|
### Subscriptions with IAM
|
|
|
|
```hcl
|
|
module "pubsub" {
|
|
source = "./modules/pubsub"
|
|
project_id = "my-project"
|
|
name = "my-topic"
|
|
subscriptions = {
|
|
test-1 = null
|
|
test-1 = null
|
|
}
|
|
subscription_iam = {
|
|
test-1 = {
|
|
"roles/pubsub.subscriber" = ["user:user1@ludomagno.net"]
|
|
}
|
|
}
|
|
}
|
|
# tftest:modules=1:resources=3
|
|
```
