現在、Gitlab CI用にKubernetesクラスタを使用しようとしています。 あまり良くない文書（https://docs.gitlab.com/runner/install/kubernetes.html）に続いて、Gitlab CIセクションのトークンをランナーに手作業で登録して、別のトークンを取得して、配置用に使用するConfigMapで使用することができました。私はGitlabランナーセクションでランナーを見ることが私は仕事を起動するたびに、新しい作成したポッドが保留のままにこれら二つでGitlab CI runnerをKubernetesで実行しているときのポッドのステータス
-ConfigMap

-Deployment

状態。
私はそれを修正したいと思いますが、私は知っているすべてのノードとポッドは、これらのイベントを取得することです：

なぜこれが起こっているのか？
EDIT：kubectlが追加について説明します。
