文字

描述

列表服务

使用

docker service ls [OPTIONS]

备选方案

名字,简写

默认

描述

--filter, -f


根据提供的条件过滤输出

--format


使用Go模板的漂亮打印服务

--quiet,-q

只显示ID

父命令

命令

描述

docker service

管理服务

相关命令

命令

描述

docker service create

创建一项新服务

docker service inspect

显示一项或多项服务的详细信息

docker service logs

获取服务或任务的日志

docker service ls

列出服务

docker service ps

列出一项或多项服务的任务

docker service rm

删除一项或多项服务

docker service scale

扩展一个或多个复制服务

docker service update

更新服务

扩展描述

此命令在以管理器为目标运行时,列出服务在群集中运行。

实例

在管理节点上:

$ docker service ls

ID            NAME      MODE        REPLICAS    IMAGE
c8wgl7q4ndfd  frontend  replicated  5/5         nginx:alpine
dmu1ept4cxcf  redis     replicated  3/3         redis:3.0.6iwe3278osahj  mongo     global      7/7         mongo:3.3

REPLICAS列显示两个实际和所需服务的任务数。

过滤

过滤标志(-f--filter)格式为 “key = value”。如果有多个过滤器,则传递多个标志(例如--filter "foo=bar" --filter "bif=baz"

目前支持的过滤器是:

  • ID

  • 标签

  • 模式

  • 名称

ID

id筛选器匹配服务标识的全部或部分。

$ docker service ls -f "id=0bcjw"ID            NAME   MODE        REPLICAS  IMAGE
0bcjwfh8ychr  redis  replicated  1/1       redis:3.0.6

标签

标签过滤器根据单独存在标签或标签和值来匹配服务。

下面的筛选器将所有服务与project标签,不论其价值:

$ docker service ls --filter label=project
ID            NAME       MODE        REPLICAS  IMAGE
01sl1rp6nj5u  frontend2  replicated  1/1       nginx:alpine
36xvvwwauej0  frontend   replicated  5/5       nginx:alpine
74nzcxxjv6fq  backend    replicated  3/3       redis:3.0.6

下面的筛选器只将服务与project标签上带有project-a价值。

$ docker service ls --filter label=project=project-a
ID            NAME      MODE        REPLICAS  IMAGE
36xvvwwauej0  frontend  replicated  5/5       nginx:alpine
74nzcxxjv6fq  backend   replicated  3/3       redis:3.0.6

模式

mode过滤器上的模式(或者匹配replicated或者global服务的)。

以下筛选器仅匹配global服务。

$ docker service ls --filter mode=global
ID                  NAME                MODE                REPLICAS            IMAGE
w7y0v2yrn620        top                 global              1/1                 busybox

名称

name筛选器与服务名称的全部或部分匹配。

以下过滤器将匹配包含名称的服务redis

$ docker service ls --filter name=redis
ID            NAME   MODE        REPLICAS  IMAGE
0bcjwfh8ychr  redis  replicated  1/1       redis:3.0.6

格式化

格式化选项(--format)使用 Go 模板漂亮地打印服务输出。

Go模板的有效占位符列在下面:

占位符

描述

.ID

服务ID

.Name

服务名称

.Mode

服务模式(复制,全局)

.Replicas

服务副本

.Image

服务形象

.Ports

服务端口以入口模式发布

当使用--format选项,service ls命令将按照模板声明的方式输出数据,或者在使用table指令,还包括列标题。

下面的示例使用的模板没有报头,并输出IDMode以及Replicas通过所有服务冒号分隔的条目:

$ docker service ls --format "{{.ID}}: {{.Mode}} {{.Replicas}}"0zmvwuiu3vue: replicated 10/10fm6uf97exkul: global 5/5
