Start with a normal docker ps output:

$ docker ps

What fields do we have to work with, lets use the --format {{json .}} | jq . trick to show all of the possible fields:

$ docker ps --format '{{json .}}' | jq .
{

Lets pick our favorite fields:

$ docker ps --format 'table {{.Names}}\t{{.Image}}\t{{.Command}}\t{{.ID}}\t{{.Status}}'

Hmm, those names are rather long, lets truncate them:

$ docker ps --format 'table {{printf "%.20s" .Names}}\t{{.Image}}\t{{.Command}}\t{{.ID}}\t{{printf "%.15s" .Status}}'
NAMES                  IMAGE                            COMMAND                  CONTAINER ID        STATUS

prometheus_prometheu   prom/prometheus:latest           "/bin/prometheus --c…"   822f8207aee0        Up 18 hours
prometheus_alertmana   prom/alertmanager:latest         "/bin/alertmanager -…"   8c3f044d503b        Up 18 hours
prometheus_cadvisor.   google/cadvisor:latest           "/usr/bin/cadvisor -…"   7d32bb10f579        Up 18 hours

Thats looking pretty good, lets make it our default docker ps output by adding it to our ~/.docker/config.json (leave the auths sections alone if you don't want to have to docker login to your registries again):

$ cat ~/.docker/config.json
{
   "experimental": "enabled",
   "psFormat": "table {{printf \"%.20s\" .Names}}\t{{.Image}}\t{{.Command}}\t{{.ID}}\t{{printf \"%.15s\" .Status}}",
   "auths": {
   ......
   }
}

Lets see what that did to the default docker ps command:

$ docker ps
NAMES                  IMAGE                            COMMAND                  CONTAINER ID        STATUS
