Namespace is ignored when using ReadAllPrefixCidrs #131
Description
Using file.json ( other storage types untested ), creating new prefixes in separate namespaces works fine. However, when usingReadAllPrefixCidrs, it always returns values from the root namespace, completely ignoring the ones in the namespace it should query.
Code sample:
package main
import (
context "context"
"log"
"time"
"github.com/metal-stack/go-ipam"
)
var (
rootNamespace = "root"
ns = "tenant-a"
rootPrfx = "10.76.0.0/25"
contextPrfx = "10.76.0.128/25"
)
func main() {
rootCtx := context.Background()
rootCtx, cancel := context.WithTimeout(rootCtx, 5*time.Second)
defer cancel()
storage := ipam.NewLocalFile(rootCtx, "file.json")
ipamer := ipam.NewWithStorage(storage)
ipamer.CreateNamespace(rootCtx, ns)
log.Printf("\nCreated namespace %v", ns)
log.Printf("\nCreating CIDR %v in %v namespace", rootPrfx, rootNamespace)
_, err := ipamer.NewPrefix(rootCtx, rootPrfx)
if err != nil {
panic(err.Error())
}
tenantCtx := ipam.NewContextWithNamespace(rootCtx, ns)
log.Printf("\nCreating CIDR %v in %v namespace", contextPrfx, ns)
_, err = ipamer.NewPrefix(tenantCtx, contextPrfx)
if err != nil {
panic(err.Error())
}
rootCidrs, err := ipamer.ReadAllPrefixCidrs(rootCtx)
if err != nil {
panic(err.Error())
}
log.Printf("Discovered context cidr %v for %v", rootCidrs, rootNamespace)
contextCidrs, err := ipamer.ReadAllPrefixCidrs(tenantCtx)
if err != nil {
panic(err.Error())
}
log.Printf("Discovered context cidr %v for %v", contextCidrs, ns)
}
