Use var.gitlab_host for the A record name.
The chart already allows overriding the GitLab hostname, but this record is pinned to "gitlab". Any non-default gitlab_host will publish the wrong DNS name and the ingress host won't resolve.

Add this secret to helm_release.gitlab.depends_on.
helm/gitlab/values.yaml now makes the release depend on gitlab-initial-root-password, but the provided terraform/helm.tf snippet still only waits on the older secrets. On a fresh apply, Helm can start before this secret exists and fail the install.

Add timeout to data source to wait for load balancer provisioning.
The depends_on = [helm_release.ingress_nginx] only ensures the Service is created. DigitalOcean's cloud controller provisioning the load balancer IP in status.load_balancer.ingress is asynchronous and can complete after the helm release, causing the DNS record creation in terraform/dns.tf line 9 to fail when it tries to access an empty ingress list on first apply.
Add a timeouts block to the data source or use a resource-based waiter to poll until the load balancer is ready before the DNS record is created.

What is the Terraform variable validation block syntax for string variables?Repository: clofour/gitlab-kubernetes
Length of output: 162
🌐 Web query:
Terraform variable validation block syntax for string trimspace
💡 Result:
The syntax for a Terraform variable validation block using trimspace checks if a string variable has no leading or trailing whitespace by comparing the original value to its trimmed version. Example: variable "hostname" { type = string validation { condition = var.hostname == trimspace(var.hostname) error_message = "Hostname must not contain leading or trailing whitespace." } } This uses the built-in trimspace function, which removes Unicode whitespace (spaces, tabs, newlines, etc.) from both ends of the string. The validation block requires a boolean condition expression that must evaluate to true and a descriptive error_message. Terraform evaluates this during plan creation; if false, it errors with the message and halts. You can add multiple validation blocks for different checks or use trimspace(var.name) in locals for normalization without validation.

Reject empty ACME emails at plan time.
This variable is required, but "" and whitespace-only values still pass and render an invalid ClusterIssuer manifest. Add validation so the failure happens during terraform plan, not after cert-manager tries to apply the manifest.
