Types ¶
type Changes ¶
type Changes struct {
// Records that need to be created
Create []endpoint.Endpoint
// Records that need to be updated (current data)
UpdateOld []endpoint.Endpoint
// Records that need to be updated (desired data)
UpdateNew []endpoint.Endpoint
// Records that need to be deleted
Delete []endpoint.Endpoint
}
Changes holds lists of actions to be executed by dns providers
type Plan ¶
type Plan struct {
// List of current records
Current []endpoint.Endpoint
// List of desired records
Desired []endpoint.Endpoint
// List of changes necessary to move towards desired state
// Populated after calling Calculate()
Changes Changes
}
Plan can convert a list of desired and current records to a series of create, update and delete actions.
Example ¶
ExamplePlan shows how plan can be used.
foo := endpoint.Endpoint{DNSName: "foo.example.com", Target: "1.2.3.4"}
barV1 := endpoint.Endpoint{DNSName: "bar.example.com", Target: "8.8.8.8"}
barV2 := endpoint.Endpoint{DNSName: "bar.example.com", Target: "8.8.4.4"}
baz := endpoint.Endpoint{DNSName: "baz.example.com", Target: "6.6.6.6"}
// Plan where
// * foo should be deleted
// * bar should be updated from v1 to v2
// * baz should be created
plan := &Plan{
Current: []endpoint.Endpoint{foo, barV1},
Desired: []endpoint.Endpoint{barV2, baz},
}
// calculate actions
plan = plan.Calculate()
// print actions
fmt.Println("Create:", plan.Changes.Create)
fmt.Println("UpdateOld:", plan.Changes.UpdateOld)
fmt.Println("UpdateNew:", plan.Changes.UpdateNew)
fmt.Println("Delete:", plan.Changes.Delete)
Output: Create: [{baz.example.com 6.6.6.6}] UpdateOld: [{bar.example.com 8.8.8.8}] UpdateNew: [{bar.example.com 8.8.4.4}] Delete: [{foo.example.com 1.2.3.4}]
