过滤 (--filter)
过滤标志（-f 或 --filter）的格式为 key=value 对。如果存在多个过滤器，则传递多个标志（例如 --filter "foo=bar" --filter "bif=baz"）。多个过滤标志组合为 OR 过滤器。例如，-f name=redis.1 -f name=redis.7 将返回 redis.1 和 redis.7 这两个任务。
当前支持的过滤器有
id
id 过滤器匹配任务 ID 的全部或前缀。
$ 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
name
name 过滤器匹配任务名称。
$ 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
node
node 过滤器匹配节点名称或节点 ID。
$ 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

6jj1m02freg1 voting_visualizer.1 dockersamples/visualizer:stable node1 Running Running 18 minutes ago
desired-state
desired-state 过滤器可以接受 running、shutdown、ready 或 accepted 的值。
$ docker stack ps -f "desired-state=running" voting

xim5bcqtgk1b voting_worker.1 dockersamples/examplevotingapp_worker:latest node2 Running Running 21 minutes ago

格式化输出 (--format)
格式化选项（--format）使用 Go 模板漂亮地打印任务输出。
Go 模板的有效占位符如下所示
| 占位符 | 描述 |
|---|---|
.ID | 任务 ID |
.Name | 任务名称 |
.Image | 任务镜像 |
.Node | 节点 ID |
.DesiredState | 任务的期望状态 (running, shutdown, 或 accepted) |
.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 命令将严格按照模板声明的格式输出数据，或者在使用 table 指令时，还会包含列标题。
以下示例使用不带标题的模板，并为所有任务输出以冒号（:）分隔的 Name 和 Image 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
要以 JSON 格式列出所有任务，请使用 json 指令
$ docker stack ps --format json myapp
{"CurrentState":"Preparing 23 seconds ago","DesiredState":"Running","Error":"","ID":"2ufjubh79tn0","Image":"localstack/localstack:latest","Name":"myapp_localstack.1","Node":"docker-desktop","Ports":""}
{"CurrentState":"Running 20 seconds ago","DesiredState":"Running","Error":"","ID":"roee387ngf5r","Image":"redis:6.0.9-alpine3.12","Name":"myapp_redis.1","Node":"docker-desktop","Ports":""}
{"CurrentState":"Preparing 13 seconds ago","DesiredState":"Running","Error":"","ID":"yte68ouq7glh","Image":"postgres:13.2-alpine","Name":"myapp_repos-db.1","Node":"docker-desktop","Ports":""}
不将 ID 映射到名称 (--no-resolve)
--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

不截断输出 (--no-trunc)
部署服务时，docker 解析服务镜像的摘要（digest），并将服务固定在该摘要上。摘要默认不显示，但如果使用 --no-trunc 则会打印出来。--no-trunc 选项还会显示非截断的任务 ID 和错误消息，如下所示
$ docker stack ps --no-trunc voting

仅显示任务 ID (-q, --quiet)
-q 或 --quiet 选项仅显示堆栈中任务的 ID。此示例输出 voting 堆栈的所有任务 ID
$ docker stack ps -q voting
xim5bcqtgk1b

rx5yo0866nfx
tz6j82jnwrx7
w48spazhbmxc
6jj1m02freg1
kqgdmededccb
t72q3z038jeh
此选项可用于执行批量操作。例如，您可以使用任务 ID 作为其他命令（例如 docker inspect）的输入。以下示例检查 voting 堆栈中的所有任务
$ docker inspect $(docker stack ps -q voting)
