Properties
Truto's stable unified identifier for this object. Opaque; use provider_id to address the object in the provider's own console or API.
Zones the group may launch into.
When Truto actually read this object from the provider, in UTC ISO 8601 with the offset present — not the request time, and not a provider timestamp.
When the object was created at the provider, in UTC ISO 8601. Null when the provider does not record one - see unreadable_fields.
How many machines the group is trying to run right now.
How long a new machine is spared from health checks.
Health checks that decide when a machine is replaced, normalised. instance: the provider's machine status checks (on AWS EC2); load_balancer: load balancer target health (ELB); service_network: service network target health (VPC Lattice); block_volume: attached volume health (EBS). instance alone means a machine failing a load balancer check is not replaced. The provider's own value is in remote_data.
instanceload_balancerservice_networkblock_volumeunknown
Machines currently in the group.
Zone the machine runs in.
The group's health verdict for the machine. The provider's own value is in remote_data.
healthyunhealthyunknown
The machine's own id, verbatim.
Machine type, verbatim.
Where the machine is in the group lifecycle, normalised. pending and terminating include their lifecycle-hook wait steps; warm_pool: a pre-initialised machine in the warm pool; standby: taken out of service but kept in the group. The provider's own value is in remote_data.
pendingin_servicestandbydetachingdetachedterminatingterminatedwarm_poolunknown
Whether scale-in may not remove this machine.
The launch template the group launches from (on AWS an lt- id, also when it comes from a mixed instances policy). Null when the group uses a legacy launch configuration.
The template version the group uses, verbatim ($Latest, $Default or a number on AWS).
Load balancer target groups (ARNs) and classic load balancer names the group registers its machines with.
Most machines the group may run.
Fewest machines the group keeps.
The group's name, verbatim.
The provider's own type string, unmodified — for example 'AWS::S3::Bucket', 'aws_iam_role', 'Microsoft.Sql/servers'. Used for display and drill-down.
Which cloud this object was read from.
awsazuregcp
The provider's own identifier, passed through verbatim — a full ARN, resource id, or self-link. Never truncated, prefixed, or normalized.
Where the object is located. 'global' denotes genuinely global resources (e.g. IAM, GCP VPC networks) rather than a guessed region. A substituted region (when none is derivable) is flagged in unreadable_fields.
Raw data returned from the remote API call.
The identity the scaling service acts as (on AWS the service-linked role).
The target's id.
deleting while the group is being deleted; null otherwise. The provider's own value is in remote_data.
deletingunknown
Subnets the group launches into.
Scaling processes that are suspended, verbatim (Launch, Terminate, HealthCheck, ReplaceUnhealthy ... on AWS). A suspended HealthCheck or ReplaceUnhealthy stops unhealthy machines being replaced.
Key-value pairs exactly as the customer set them: no case folding, key/value normalization, or merging of separate provider concepts. An empty object means no tags; tags that could not be read appear in unreadable_fields instead.
Fields on this object that could not be read, and why. An empty array means everything was read. Use this to tell a real value from a missing one.
Explanation of the reason, where one adds anything.
The property on this resource that could not be read.
Why the field could not be read. available_on_get: Not read on list to keep the list fast; call GET for this resource's id to get it.
not_supported_by_providernot_configuredpermission_deniednot_collectedcollection_errorpartially_collectedavailable_on_get
When the object was last modified at the provider, in UTC ISO 8601. Null when the provider does not record one - see unreadable_fields.
Whether the group launches from a legacy launch definition the provider no longer extends (an AWS launch configuration). False on providers without one.
