ポッド使用Redisのミラーを作成する方法によって展開、。Redisのはkubectlをロギングすることで始めます。

To fix this is                                                     sue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot.

コマンドYAMLショットを完了します展開、アップロードするために作成

// kubectl create deploy hwcka-003-1-chenjo --image redis:alpine --dry-run -o yaml > ex1.yaml
// cat ex1.yaml

2.演習2

コマンドラインは、展開、コピー数3を作成し、ミラーはnginxのです：最新の。1.9.1：その後、nginxのをアップグレードするためにスクロールします。
名前の展開<hwcka-003-2-你的华为云id>

[root@svn ch03]# kubectl run hwcka-003-2-chenjo --replicas 3 --image nginx:latest
kubectl run --generator=deployment/apps.v1 is DEPRECATED and will be removed in a future version. Use kubectl run --generator=run-pod/v1 or kubectl create instead.
deployment.apps/hwcka-003-2-chenjo created

[root@svn ch03]# kubectl rollout history deploy hwcka-003-2-chenjo
