<!--
|
||||
In this exercise you will use kubectl to fetch all of the Pods
|
||||
running in a cluster, and format the output to pull out the list
|
||||
of Containers for each.
|
||||
-->
|
||||
在本练习中，您将使用 kubectl 来获取集群中运行的所有 Pod，并格式化输出来提取每个 pod 中的容器列表。
|
||||
|
||||
<!--
|
||||
## List all Containers in all namespaces
|
||||
|
||||
- Fetch all Pods in all namespaces using `kubectl get pods --all-namespaces`
|
||||
- Format the output to include only the list of Container image names
|
||||
using `-o jsonpath={..image}`. This will recursively parse out the
|
||||
`image` field from the returned json.
|
||||
- See the [jsonpath reference](/docs/user-guide/jsonpath/)
|
||||
for further information on how to use jsonpath.
|
||||
- Format the output using standard tools: `tr`, `sort`, `uniq`
|
||||
- Use `tr` to replace spaces with newlines
|
||||
- Use `sort` to sort the results
|
||||
- Use `uniq` to aggregate image counts
|
||||
-->
|
||||
## 列出所有命名空间下的所有容器
|
||||
|
||||
- 使用 `kubectl get pods --all-namespaces` 获取所有命名空间下的所有 Pod
|
||||
- 使用 `-o jsonpath={..image}` 来格式化输出，以仅包含容器镜像名称。
|
||||
这将以递归方式从返回的 json 中解析出 `image` 字段。
|
||||
- 参阅 [jsonpath reference](/docs/user-guide/jsonpath/) 来获取更多关于如何使用 jsonpath 的信息。
|
||||
- 使用标准化工具来格式化输出：`tr`, `sort`, `uniq`
|
||||
- 使用 `tr` 以用换行符替换空格
|
||||
- 使用 `sort` 来对结果进行排序
|
||||
- 使用 `uniq` 来聚合镜像计数
|
||||
|
||||
```sh
|
||||
kubectl get pods --all-namespaces -o jsonpath="{..image}" |\
|
||||
tr -s '[[:space:]]' '\n' |\
|
||||
sort |\
|
||||
uniq -c
|
||||
```
|
||||
|
||||
<!--
|
||||
The above command will recursively return all fields named `image`
|
||||
for all items returned.
|
||||
|
||||
As an alternative, it is possible to use the absolute path to the image
|
||||
field within the Pod. This ensures the correct field is retrieved
|
||||
even when the field name is repeated,
|
||||
e.g. many fields are called `name` within a given item:
|
||||
-->
|
||||
上面的命令将递归获取所有返回项目的名为 `image` 的字段。
|
||||
|
||||
作为替代方案，可以使用 Pod 的镜像字段的绝对路径。这确保即使字段名称重复的情况下也能检索到正确的字段，例如，特定项目中的许多字段都称为 `name`：
|
||||
|
||||
```sh
|
||||
kubectl get pods --all-namespaces -o jsonpath="{.items[*].spec.containers[*].image}"
|
||||
```
|
||||
|
||||
<!--
|
||||
The jsonpath is interpreted as follows:
|
||||
|
||||
- `.items[*]`: for each returned value
|
||||
- `.spec`: get the spec
|
||||
- `.containers[*]`: for each container
|
||||
- `.image`: get the image
|
||||
-->
|
||||
jsonpath 解释如下：
|
||||
|
||||
- `.items[*]`: 对于每个返回的值
|
||||
- `.spec`: 获取 spec
|
||||
- `.containers[*]`: 对于每个容器
|
||||
- `.image`: 获取镜像
|
||||
|
||||
{{< note >}}
|
||||
<!--
|
||||
**Note:** When fetching a single Pod by name, e.g. `kubectl get pod nginx`,
|
||||
the `.items[*]` portion of the path should be omitted because a single
|
||||
Pod is returned instead of a list of items.
|
||||
-->
|
||||
**注意：** 按名字获取单个 Pod 时，例如 `kubectl get pod nginx`，路径的 `.items[*]` 部分应该省略，因为返回的是一个 Pod 而不是一个项目列表。
|
||||
{{< /note >}}
|
||||
|
||||
<!--
|
||||
## List Containers by Pod
|
||||
|
||||
The formatting can be controlled further by using the `range` operation to
|
||||
iterate over elements individually.
|
||||
-->
|
||||
## 列出 Pod 中的容器
|
||||
|
||||
可以使用 `range` 操作进一步控制格式化，以单独操作每个元素。
|
||||
|
||||
```sh
|
||||
kubectl get pods --all-namespaces -o=jsonpath='{range .items[*]}{"\n"}{.metadata.name}{":\t"}{range .spec.containers[*]}{.image}{", "}{end}{end}' |\
|
||||
sort
|
||||
```
|
||||
|
||||
<!--
|
||||
## List Containers filtering by Pod label
|
||||
|
||||
To target only Pods matching a specific label, use the -l flag. The
|
||||
following matches only Pods with labels matching `app=nginx`.
|
||||
-->
|
||||
## 列出以 label 过滤后的 Pod 的所有容器
|
||||
|
||||
要获取匹配特定标签的 Pod，请使用 -l 参数。以下匹配仅与标签 `app=nginx` 相符的 Pod。
|
||||
|
||||
```sh
|
||||
kubectl get pods --all-namespaces -o=jsonpath="{..image}" -l app=nginx
|
||||
```
|
||||
|
||||
<!--
|
||||
## List Containers filtering by Pod namespace
|
||||
|
||||
To target only pods in a specific namespace, use the namespace flag. The
|
||||
following matches only Pods in the `kube-system` namespace.
|
||||
-->
|
||||
## 列出以命名空间过滤后的 Pod 的所有容器
|
||||
|
||||
要获取匹配特定命名空间的 Pod，请使用 namespace 参数。以下仅匹配 `kube-system` 命名空间下的 Pod。
|
||||
|
||||
```sh
|
||||
kubectl get pods --namespace kube-system -o jsonpath="{..image}"
|
||||
```
|
||||
|
||||
<!--
|
||||
## List Containers using a go-template instead of jsonpath
|
||||
|
||||
As an alternative to jsonpath, Kubectl supports using [go-templates](https://golang.org/pkg/text/template/)
|
||||
for formatting the output:
|
||||
-->
|
||||
## 使用 go-template 代替 jsonpath 来获取容器
|
||||
|
||||
作为 jsonpath 的替代，Kubectl 支持使用 [go-templates](https://golang.org/pkg/text/template/) 来格式化输出：
|
||||
|
||||
|
||||
```sh
|
||||
kubectl get pods --all-namespaces -o go-template --template="{{range .items}}{{range .spec.containers}}{{.image}} {{end}}{{end}}"
|
||||
