Troubleshoot deployment issues¶
This guide provides step-by-step troubleshooting actions to remediate deployment issues. We hope you don’t need this guide. If you encounter an issue and aren’t able to address it via this guide, please raise an issue here.
1. Terraform failed to deploy the Charmed Aether SD-Core with Unable to create model error¶
Symptoms¶
The terraform apply -auto-approve command fails with an error indicating that the Juju model could not be created:
Plan: 72 to add, 0 to change, 0 to destroy.
juju_model.private5g: Creating...
│ Error: Client Error
│ with juju_model.private5g,
│ on main.tf line 1, in resource "juju_model" "private5g":
│ 1: resource "juju_model" "private5g" {
│ Unable to create model, got error: failed to open kubernetes client: annotations map[controller.juju.is/id:ced7016b-3a63-4133-8988-cf33068c3cdf
│ model.juju.is/id:2abfe7ab-9e40-4e0d-8158-53450c47b2db] for namespace "private5g" not valid must include map[controller.juju.is/id:ced7016b-3a63-4133-8988-cf33068c3cdf
│ model.juju.is/id:9755936b-8084-4397-8a67-28773b361dfa] (not valid)
Recommended Actions¶
Validate whether a Juju model already exists with the same name:
$ juju models
controller: microk8s-localhost
Model Cloud/Region Type Status Units Access Last connection
controller microk8s/localhost kubernetes available 1 admin just now
private5g* microk8s/localhost kubernetes destroying - admin 6 minutes ago
sdcore microk8s/localhost kubernetes available 19 admin 2024-10-04
Choose a model name that does not exist in the Juju controller. Read this guide for more information.
2. Terraform failed to deploy Charmed Aether SD-Core with Connection error, please check the controller_addresses property set on the provider error¶
Symptoms¶
The terraform apply -auto-approve command fails with an error indicating that the Juju controller couldn’t be connected to:
$ terraform apply --auto-approve
│ Error: Invalid provider configuration
│ Provider "registry.terraform.io/juju/juju" requires explicit configuration. Add a provider block to the root module and configure the provider's required arguments as described in
│ the provider documentation.
│ Error: dial tcp 10.152.183.251:17070: i/o timeout
│ with provider["registry.terraform.io/juju/juju"],
│ on <empty> line 0:
│ (source code not available)
│ Connection error, please check the controller_addresses property set on the provider
Recommended Actions¶
Validate that the Juju controller exists.
First, list the available Juju controllers:
$ juju controllers
Use --refresh option with this command to see the latest information.
Controller Model User Access Cloud/Region Models Nodes HA Version
microk8s-localhost* private5g admin superuser microk8s/localhost 9 - - 3.4.5
If your controller does not show up in the list, please follow this guide to create a Juju controller.
Otherwise, follow this guide to remove your broken Juju controller.
Once the controller is removed, please make sure that the controller namespace is not found in your MicroK8s cluster:
$ kubectl get ns controller-<your-controller-name>
NAME STATUS AGE
controller-<your-controller-name> Active 20d
If your controller namespace appears as Active in the command output, remove the namespace manually:
$ kubectl delete ns controller-<your-controller-name>
namespace "controller-<your-controller-name>" deleted
After successful removal of the controller namespace, please follow this guide to create a new Juju controller.
