external-dns-aws-migrator\n\nUtility that helps migrating old (not managed by [external-dns][external-dns]) route53 resource record sets from a hosted zone to being managed by external-dns and let update based on the kubernetes ingress address (set by other ingress controllers)\n\n## Motivation\n\nSometimes you add external-dns to your clusters and the new flow doesn't have your old host entries from route53 but you want these entries being tracked and managed by external-dns, to do this you would need to create a txt entry for each one, this tool helps doing this migration all at once, filtered by hosts, with multiple external-dns...\n\n## When should I use this?\n\nYou are using Kubernetes, AWS, you already have dns entries in route53 (manually or managed by another tool) and you want to start using external-dns to automate ingress loadbalancer addresses in route53.\n\n## Usage\n\nexternal-dns-aws-migrator reads hosts from the stdin (one per line) and tries to adopt the entries  so the external-dns starts managing the entries.\n\nExample:\n\nGet all ingress hosts from a cluster.\n\n```bash\nkubectl get ingress \\\n    --all-namespaces  \\\n    -o jsonpath='{.items[*].spec.rules[*].host}' \\\n    | sed \"s/ /\\n/g\" \u003e /tmp/ingresses.txt\n```\n\nNow adopt in dry run mode(only print the ones that will be applied) all `slok.xyz` hosts with the external-dns instance identifier `slok-xyz`:\n\n```bash\nexternal-dns-aws-migrator \\\n    -filter \".*\\.slok\\.xyz$\" \\\n    --txt-owner-id \"slok-xyz\" \\\n    --dry-run \u003c /tmp/ingresses.txt \n```\n\n[external-dns]:
