## 创建和探究一个nginx deployment
|
||||
|
||||
你可以通过创建一个Kubernetes Deployment对象来运行一个应用, 可以在一个YAML文件中描述Deployment. 例如, 下面这个YAML文件描述了一个运行nginx:1.7.9 Docker镜像的Deployment:
|
||||
|
||||
{{< code file="deployment.yaml" >}}
|
||||
|
||||
|
||||
1. 通过YAML文件创建一个Deployment:
|
||||
|
||||
kubectl create -f https://k8s.io/docs/tasks/run-application/deployment.yaml
|
||||
|
||||
1. 展示Deployment相关信息:
|
||||
|
||||
kubectl describe deployment nginx-deployment
|
||||
|
||||
user@computer:~/website$ kubectl describe deployment nginx-deployment
|
||||
Name: nginx-deployment
|
||||
Namespace: default
|
||||
CreationTimestamp: Tue, 30 Aug 2016 18:11:37 -0700
|
||||
Labels: app=nginx
|
||||
Annotations: deployment.kubernetes.io/revision=1
|
||||
Selector: app=nginx
|
||||
Replicas: 2 desired | 2 updated | 2 total | 2 available | 0 unavailable
|
||||
StrategyType: RollingUpdate
|
||||
MinReadySeconds: 0
|
||||
RollingUpdateStrategy: 1 max unavailable, 1 max surge
|
||||
Pod Template:
|
||||
Labels: app=nginx
|
||||
Containers:
|
||||
nginx:
|
||||
Image: nginx:1.7.9
|
||||
Port: 80/TCP
|
||||
Environment: <none>
|
||||
Mounts: <none>
|
||||
Volumes: <none>
|
||||
Conditions:
|
||||
Type Status Reason
|
||||
---- ------ ------
|
||||
Available True MinimumReplicasAvailable
|
||||
Progressing True NewReplicaSetAvailable
|
||||
OldReplicaSets: <none>
|
||||
NewReplicaSet: nginx-deployment-1771418926 (2/2 replicas created)
|
||||
No events.
|
||||
|
||||
1. 列出deployment创建的pods:
|
||||
|
||||
kubectl get pods -l app=nginx
|
||||
|
||||
NAME READY STATUS RESTARTS AGE
|
||||
nginx-deployment-1771418926-7o5ns 1/1 Running 0 16h
|
||||
nginx-deployment-1771418926-r18az 1/1 Running 0 16h
|
||||
|
||||
1. 展示某一个pod信息:
|
||||
|
||||
kubectl describe pod <pod-name>
|
||||
|
||||
该处 `<pod-name>` 指某一pod的名称.
|
||||
|
||||
## 更新deployment
|
||||
|
||||
你可以通过更新一个新的YAML文件来更新deployment. 下面的YAML文件指定该deployment镜像更新为nginx 1.8.
|
||||
|
||||
{{< code file="deployment-update.yaml" >}}
|
||||
|
||||
1. 应用新的YAML:
|
||||
|
||||
kubectl apply -f https://k8s.io/docs/tutorials/stateless-application/deployment-update.yaml
|
||||
|
||||
1. 查看该deployment创建的pods以新的名称同时删除旧的pods:
|
||||
|
||||
kubectl get pods -l app=nginx
|
||||
|
||||
## 通过增加副本数来弹缩应用
|
||||
|
||||
你可以通过应用新的YAML文件来增加Deployment中pods的数量. 该YAML文件将`replicas`设置为4, 指定该Deployment应有4个pods:
|
||||
|
||||
{{< code file="deployment-scale.yaml" >}}
|
||||
|
||||
1. 应用新的YAML文件:
|
||||
|
||||
kubectl apply -f https://k8s.io/docs/tutorials/stateless-application/deployment-scale.yaml
|
||||
|
||||
1. 验证Deployment有4个pods:
|
||||
|
||||
kubectl get pods -l app=nginx
|
||||
|
||||
输出的结果类似于:
|
||||
|
||||
NAME READY STATUS RESTARTS AGE
|
||||
nginx-deployment-148880595-4zdqq 1/1 Running 0 25s
|
||||
nginx-deployment-148880595-6zgi1 1/1 Running 0 25s
|
||||
nginx-deployment-148880595-fxcez 1/1 Running 0 2m
|
||||
nginx-deployment-148880595-rwovn 1/1 Running 0 2m
|
||||
|
||||
## 删除deployment
|
||||
|
||||
通过名称删除deployment:
|
||||
|
||||
kubectl delete deployment nginx-deployment
|
||||
|
||||
## ReplicationControllers -- 旧的方式
|
||||
|
||||
创建一个多副本应用首选方法是使用Deployment,反过来使用ReplicaSet. 在Deployment和ReplicaSet加入到Kubernetes之前, 多副本应用通过[ReplicationController](/docs/concepts/workloads/controllers/replicationcontroller/)来配置.
