过滤

过滤标志（-f或--filter）格式是一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，-f name=redis.1 -f name=redis.7返回两者redis.1和redis.7任务。

目前支持的过滤器是：

  • ID

  • 名称

  • 节点

  • 期望的状态

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

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

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running，shutdown，或accepted。

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

格式化

格式化选项（--format）可以很好地打印使用Go模板输出的任务。

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 任务图像
.Node 节点ID
.DesiredState任务的期望状态（运行，关闭或接受）
.CurrentState 任务的当前状态
.Error 错误
.Ports任务发布的端口

使用--format选项时，stack ps命令将按照模板声明输出数据，或者在使用该table指令时也包含列标题。

下面的示例使用没有标头的模板，并输出Name和Image用冒号分隔的项用于所有任务：

$ 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，而不将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

在部署服务时，docker解析服务映像的摘要，并将服务定位到该摘要。摘要默认情况下不显示，但如果--no-trunc使用则被显示。--no-trunc选项还显示未截断的任务ID和错误消息，如下所示：

$ docker stack ps --no-trunc voting

只显示任务ID

-q或--quiet选项只显示在堆栈中的任务标识。此示例输出“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，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“表决”堆栈的所有任务；

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

    {
        "ID": "xim5bcqtgk1b1gk0krq1",
