# kubectl set image 命令详解
更新现有的资源对象的容器镜像。
可使用资源对象包括（不区分大小写）：
pod (po)、replicationcontroller (rc)、deployment (deploy)、daemonset (ds)、job、replicaset (rs)
# 语法
$ image (-f FILENAME | TYPE NAME) CONTAINER_NAME_1=CONTAINER_IMAGE_1 ... CONTAINER_NAME_N=CONTAINER_IMAGE_N
# 示例
将 deployment 中的 nginx 容器镜像设置为“nginx：1.9.1”。
kubectl set image deployment/nginx busybox=busybox nginx=nginx:1.9.1
所有 deployment 和 rc 的 nginx 容器镜像更新为“nginx：1.9.1”
kubectl set image deployments,rc nginx=nginx:1.9.1 --all
将 daemonset abc 的所有容器镜像更新为“nginx：1.9.1”
kubectl set image daemonset abc *=nginx:1.9.1
从本地文件中更新 nginx 容器镜像
kubectl set image -f path/to/file.yaml nginx=nginx:1.9.1 --local -o yaml
# Flags
| Name | Shorthand | Default | Usage |
|---|---|---|---|
| all | false | select all resources in the namespace of the specified resource types | |
| allow-missing-template-keys | true | If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats. | |
| dry-run | false | If true, only print the object that would be sent, without sending it. | |
| filename | f | [] | Filename, directory, or URL to files identifying the resource to get from a server. |
| local | false | If true, set image will NOT contact api-server but run locally. | |
| no-headers | false | When using the default or custom-column output format, don't print headers (default print headers). | |
| output | o | Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns], golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://kubernetes.io/docs/user-guide/jsonpath]. | |
| output-version | DEPRECATED: To use a specific API version, fully-qualify the resource, version, and group (for example: 'jobs.v1.batch/myjob'). | ||
| record | false | Record current kubectl command in the resource annotation. If set to false, do not record the command. If set to true, record the command. If not set, default to updating the existing annotation value only if one already exists. | |
| recursive | R | false | Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory. |
| selector | l | Selector (label query) to filter on, supports '=', '==', and '!='. | |
| show-all | a | false | When printing, show all resources (default hide terminated pods.) |
| show-labels | false | When printing, show all labels as the last column (default hide labels column) | |
| sort-by | If non-empty, sort list types using this field specification. The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string. | ||
| template | Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview]. |
