kubectlの設定
minikubeのkubectlを使えるように設定します。
まずはエイリアスを設定します。
tworks55@LAPTOP-A1R0H57F:~/k8s$ echo 'alias kubectl="minikube kubectl --"' >> ~/.bashrc tworks55@LAPTOP-A1R0H57F:~/k8s$ source ~/.bashrc
kubectlのバージョンを確認します。
tworks55@LAPTOP-A1R0H57F:~/k8s$ kubectl version
> kubectl.sha256: 64 B / 64 B [--------------------------] 100.00% ? p/s 0s
> kubectl: 44.43 MiB / 44.43 MiB [--------------] 100.00% 7.18 MiB p/s 6.4s
Client Version: version.Info{Major:"1", Minor:"23", GitVersion:"v1.23.3", GitCommit:"816c97ab8cff8a1c72eccca1026f7820e93e0d25", GitTreeState:"clean", BuildDate:"2022-01-25T21:25:17Z", GoVersion:"go1.17.6", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"23", GitVersion:"v1.23.3", GitCommit:"816c97ab8cff8a1c72eccca1026f7820e93e0d25", GitTreeState:"clean", BuildDate:"2022-01-25T21:19:12Z", GoVersion:"go1.17.6", Compiler:"gc", Platform:"linux/amd64"}
kubectlでpodの状況を確認してみます。
tworks55@LAPTOP-A1R0H57F:~/k8s$ kubectl get po -A NAMESPACE NAME READY STATUS RESTARTS AGE kube-system coredns-64897985d-z5jnv 1/1 Running 0 5m20s kube-system etcd-minikube 1/1 Running 0 5m31s kube-system kube-apiserver-minikube 1/1 Running 0 5m31s kube-system kube-controller-manager-minikube 1/1 Running 0 5m31s kube-system kube-proxy-5rbbq 1/1 Running 0 5m20s kube-system kube-scheduler-minikube 1/1 Running 0 5m31s kube-system storage-provisioner 1/1 Running 1 (4m49s ago) 5m29s
これでminikubeを使う準備は終了です。
以降はハマった点があったのでメモとして残します。
dockerがインストールされていない場合
dockerがインストールされていない場合やその他のドライバーがインストールされていない場合、以下のようなエラーが発生します。
tworks55@LAPTOP-A1R0H57F:~/k8s$ minikube start
😄 minikube v1.25.2 on Ubuntu 20.04
👎 Unable to pick a default driver. Here is what was considered, in preference order:
💡 Alternatively you could install one of these drivers:
▪ docker: Not installed: exec: "docker": executable file not found in $PATH
▪ kvm2: Not installed: exec: "virsh": executable file not found in $PATH
▪ podman: Not installed: exec: "podman": executable file not found in $PATH
▪ vmware: Not installed: exec: "docker-machine-driver-vmware": executable file not found in $PATH
▪ virtualbox: Not installed: unable to find VBoxManage in $PATH
❌ Exiting due to DRV_NOT_DETECTED: No possible driver was detected. Try specifying --driver, or see https://minikube.sigs.k8s.io/docs/start/
dockerをインストールした後に以下のコマンドを実行することでminikubeが起動できます
> sudo usermod -aG docker $USER && newgrp docker
