码头工人堆栈ps

描述

列出堆栈中的任务

API 1.25+  客户端和守护程序API都必须至少为 1.25, 才能使用此命令。docker version在客户端上使用命令检查客户端和守护程序API版本。

用法

$ docker stack ps [OPTIONS] STACK

扩展说明

列出作为指定堆栈的一部分运行的任务。

笔记

这是集群管理命令,必须在集群管理器节点上执行。要了解管理人员和工作人员,请参阅文档中的“ 群集模式”部分

有关此命令的示例用法,请参阅下面的示例部分

选项

名称,简写 默认 描述
--filter-f 根据提供的条件过滤输出
--format 使用Go模板进行漂亮的打印任务
--namespace Kubernetes
要使用的Kubernetes命名空间
--no-resolve 不要将ID映射到名称
--no-trunc 不要截断输出
--quiet-q 仅显示任务ID
--kubeconfig Kubernetes
Kubernetes配置文件
--orchestrator 要使用的协调器(大量| kubernetes |全部)

例子

列出堆栈中的任务

以下命令显示了voting堆栈中的所有任务:

$ docker stack ps voting

筛选

过滤标志(-f--filter)格式为一key=value对。如果有多个过滤器,则传递多个标志(例如--filter "foo=bar" --filter "bif=baz")。多个过滤器标志被组合为一个OR过滤器。例如,同时 -f name=redis.1 -f name=redis.7返回redis.1redis.7任务。

当前支持的过滤器是:

ID

id过滤器上的全部或任务的ID的前缀匹配。

$ docker stack ps -f "id=t" voting
ID                  NAME                IMAGE               NODE         DESIRED STATE       CURRENTSTATE            ERROR  PORTS
tz6j82jnwrx7        voting_db.1         postgres:9.4        node1        Running             Running 14 minutes ago
t72q3z038jeh        voting_redis.2      redis:alpine        node3        Running             Running 14 minutes ago

名称

name过滤器的任务名称相匹配。

$ docker stack ps -f "name=voting_redis" voting
ID                  NAME                IMAGE               NODE         DESIRED STATE       CURRENTSTATE            ERROR  PORTS
w48spazhbmxc        voting_redis.1      redis:alpine        node2        Running             Running 17 minutes ago
t72q3z038jeh        voting_redis.2      redis:alpine        node3        Running             Running 17 minutes ago

节点

所述node过滤器上的节点名或节点ID相匹配。

$ docker stack ps -f "node=node1" voting
ID                  NAME                  IMAGE                                          NODE   DESIRED STATE  CURRENT STATE          ERROR  PORTS
q7yik0ks1in6        voting_result.1       dockersamples/examplevotingapp_result:before   node1  Running        Running 18 minutes ago
tz6j82jnwrx7        voting_db.1           postgres:9.4                                   node1  Running        Running 18 minutes ago

期望状态

desired-state过滤器可以取值runningshutdownreadyaccepted

$ docker stack ps -f "desired-state=running" voting
ID                  NAME                  IMAGE                                          NODE   DESIRED STATE  CURRENT STATE           ERROR  PORTS

格式设定

格式化选项(--format)使用Go模板漂亮地打印输出的任务。

下面列出了Go模板的有效占位符:

占位符 描述
.ID 任务ID
.Name 任务名称
.Image 任务图片
.Node 节点编号
.DesiredState 任务的理想状态(runningshutdown,或accepted
.CurrentState 任务的当前状态
.Error 错误
.Ports 任务发布的端口

当使用该--format选项时,该stack ps命令将完全按照模板声明的方式输出数据,或者在使用 table指令时也包括列标题。

以下示例使用没有标题的模板,Name并为所有任务输出Image用冒号(:)分隔的 和条目:

$ docker stack ps --format "{{.Name}}: {{.Image}}" voting
voting_worker.1: dockersamples/examplevotingapp_worker:latest
voting_result.1: dockersamples/examplevotingapp_result:before
voting_vote.1: dockersamples/examplevotingapp_vote:before
voting_db.1: postgres:9.4
voting_redis.1: redis:alpine
voting_visualizer.1: dockersamples/visualizer:stable
voting_vote.2: dockersamples/examplevotingapp_vote:before
voting_redis.2: redis:alpine

不要将ID映射到名称

--no-resolve选项显示任务名称的ID,但不将ID映射到名称。

$ docker stack ps --no-resolve voting
ID                  NAME                          IMAGE                                          NODE                        DESIRED STATE  CURRENT STATE            ERROR  PORTS

不要截断输出

部署服务时,泊坞窗为服务映像解析摘要,并将服务固定到该摘要。默认情况下不显示摘要,但如果--no-trunc使用摘要,则将其打印出来。该--no-trunc选项还显示了未截断的任务ID和错误消息,如下所示:

$ docker stack ps --no-trunc voting

仅显示任务ID

-q --quiet选项只显示在堆栈中的任务标识。本示例输出“投票”堆栈的所有任务ID;

$ docker stack ps -q voting
xim5bcqtgk1b
q7yik0ks1in6
rx5yo0866nfx
tz6j82jnwrx7
w48spazhbmxc
6jj1m02freg1
kqgdmededccb
t72q3z038jeh

此选项可用于执行批处理操作。例如,您可以将任务ID用作其他命令的输入,例如docker inspect。下面的示例检查“投票”堆栈的所有任务;

$ docker inspect $(docker stack ps -q voting)

    {
        "ID": "xim5bcqtgk1b1gk0krq1",
        "Version": {
