Passing In Variables At Runtime

[AdminTurnedDevOps]

Hey All,

Trying to figure out how to pass in variables at runtime. For example:

terraform apply --auto-approve -var name="value" -var location="value"

I set up a Variables interface to pass in the values (setting up the values of the variables by passing them in at runtime. Already have that covered).

		variables := map[string]interface{}{
			"name":                name,
			"resource_group_name": resourceGroupName,
			"location":            location,
			"node_count":          nodeCount,
			"k8s_version":         k8sVersion,
		}

		err = tf.Apply(context.Background())

tfVarTempFile, _ := os.CreateTemp(os.TempDir(), "tempvars-*.tfvars.json")
defer os.Remove(tfVarTempFile.Name())
configBytes, _ := json.Marshal(variables)
tfVarTempFile.Write(configBytes)
tfVarTempFile.Close()
tf.Apply(context.TODO(), tfexec.VarFile(tfVarTempFile.Name()))

This is how I did it. Not amazing but not a ton of work either.
You could also do tfexec.Var("k=v") for all pairs in your map
