This command 33 has to be run targeting a manager node. 34 35 ## Examples 36 37 ### Listing the tasks that are part of a service 38 39 The following command shows all the tasks that are part of the `redis` service: 40 41 ```bash 42 $ docker service ps redis 43 44 ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS 45 0qihejybwf1x redis.1 redis:3.0.5 manager1 Running Running 8 seconds 46 bk658fpbex0d redis.2 redis:3.0.5 worker2 Running Running 9 seconds 47 5ls5s5fldaqg redis.3 redis:3.0.5 worker1 Running Running 9 seconds 48 8ryt076polmc redis.4 redis:3.0.5 worker1 Running Running 9 seconds 49 1x0v8yomsncd redis.5 redis:3.0.5 manager1 Running Running 8 seconds 50 71v7je3el7rr redis.6 redis:3.0.5 worker2 Running Running 9 seconds 51 4l3zm9b7tfr7 redis.7 redis:3.0.5 worker2 Running Running 9 seconds 52 9tfpyixiy2i7 redis.8 redis:3.0.5 worker1 Running Running 9 seconds 53 3w1wu13yupln redis.9 redis:3.0.5 manager1 Running Running 8 seconds 54 8eaxrb2fqpbn redis.10 redis:3.0.5 manager1 Running Running 8 seconds 55 ``` 56 57 In addition to _running_ tasks, the output also shows the task history. For 58 example, after updating the service to use the `redis:3.0.6` image, the output 59 may look like this: 60 61 ```bash 62 $ docker service ps redis 63 64 ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS 65 50qe8lfnxaxk redis.1 redis:3.0.6 manager1 Running Running 6 seconds ago 66 ky2re9oz86r9 \_ redis.1 redis:3.0.5 manager1 Shutdown Shutdown 8 seconds ago 67 3s46te2nzl4i redis.2 redis:3.0.6 worker2 Running Running less than a second ago 68 nvjljf7rmor4 \_ redis.2 redis:3.0.6 worker2 Shutdown Rejected 23 seconds ago "No such image: redis@sha256:6…" 69 vtiuz2fpc0yb \_ redis.2 redis:3.0.5 worker2 Shutdown Shutdown 1 second ago 70 jnarweeha8x4 redis.3 redis:3.0.6 worker1 Running Running 3 seconds ago 71 vs448yca2nz4 \_ redis.3 redis:3.0.5 worker1 Shutdown Shutdown 4 seconds ago 72 jf1i992619ir redis.4 redis:3.0.6 worker1 Running Running 10 seconds ago 73 blkttv7zs8ee \_ redis.4 redis:3.0.5 worker1 Shutdown Shutdown 11 seconds ago 74 ``` 75 76 The number of items in the task history is determined by the 77 `--task-history-limit` option that was set when initializing the swarm. You can 78 change the task history retention limit using the 79 [`docker swarm update`](swarm_update.md) command. 80 81 When deploying a service, docker resolves the digest for the service's 82 image, and pins the service to that digest. The digest is not shown by 83 default, but is printed if `--no-trunc` is used. The `--no-trunc` option 84 also shows the non-truncated task ID, and error-messages, as can be seen below; 85 86 ```bash 87 $ docker service ps --no-trunc redis 88 89 ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS 90 50qe8lfnxaxksi9w2a704wkp7 redis.1 redis:3.0.6@sha256:6a692a76c2081888b589e26e6ec835743119fe453d67ecf03df7de5b73d69842 manager1 Running Running 5 minutes ago 91 ky2re9oz86r9556i2szb8a8af \_ redis.1 redis:3.0.5@sha256:f8829e00d95672c48c60f468329d6693c4bdd28d1f057e755f8ba8b40008682e worker2 Shutdown Shutdown 5 minutes ago 92 bk658fpbex0d57cqcwoe3jthu redis.2 redis:3.0.6@sha256:6a692a76c2081888b589e26e6ec835743119fe453d67ecf03df7de5b73d69842 worker2 Running Running 5 seconds 93 nvjljf7rmor4htv7l8rwcx7i7 \_ redis.2 redis:3.0.6@sha256:6a692a76c2081888b589e26e6ec835743119fe453d67ecf03df7de5b73d69842 worker2 Shutdown Rejected 5 minutes ago "No such image: redis@sha256:6a692a76c2081888b589e26e6ec835743119fe453d67ecf03df7de5b73d69842" 94 ``` 95 96 ## Filtering 97 98 The filtering flag (`-f` or `--filter`) format is a `key=value` pair. If there 99 is more than one filter, then pass multiple flags (e.g. `--filter "foo=bar" --filter "bif=baz"`). 100 Multiple filter flags are combined as an `OR` filter. For example, 101 `-f name=redis.1 -f name=redis.7` returns both `redis.1` and `redis.7` tasks. 102 103 The currently supported filters are: 104 105 * [id](#id) 106 * [name](#name) 107 * [node](#node) 108 * [desired-state](#desired-state) 109 110 111 #### ID 112 113 The `id` filter matches on all or a prefix of a task's ID. 114 115 ```bash 116 $ docker service ps -f "id=8" redis 117 118 ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS 119 8ryt076polmc redis.4 redis:3.0.6 worker1 Running Running 9 seconds 120 8eaxrb2fqpbn redis.10 redis:3.0.6 manager1 Running Running 8 seconds 121 ``` 122 123 #### Name 124 125 The `name` filter matches on task names. 126 127 ```bash 128 $ docker service ps -f "name=redis.1" redis 129 ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS 130 qihejybwf1x5 redis.1 redis:3.0.6 manager1 Running Running 8 seconds 131 ``` 132 133 134 #### Node 135 136 The `node` filter matches on a node name or a node ID. 137 138 ```bash 139 $ docker service ps -f "node=manager1" redis 140 ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS 141 0qihejybwf1x redis.1 redis:3.0.6 manager1 Running Running 8 seconds 142 1x0v8yomsncd redis.5 redis:3.0.6 manager1 Running Running 8 seconds 143 3w1wu13yupln redis.9 redis:3.0.6 manager1 Running Running 8 seconds 144 8eaxrb2fqpbn redis.10 redis:3.0.6 manager1 Running Running 8 seconds 145 ``` 146 147 148 #### desired-state 149 150 The `desired-state` filter can take the values `running`, `shutdown`, and `accepted`. 151 152 153 ## Related information 154 155 * [service create](service_create.md) 156 * [service inspect](service_inspect.md) 157 * [service logs](service_logs.md) 158 * [service ls](service_ls.md) 159 * [service rm](service_rm.md) 160 * [service scale](service_scale.md) 161 * [service update](service_update.md)
