How to sort or order results docker ps --format?
Format and Order docker ps
List containers
docker ps
Synopsis
docker ps [--format="TEMPLATE"]
--format="TEMPLATE"
Pretty-print containers using a Go template.
Valid placeholders:
.ID - Container ID
.Image - Image ID
.Command - Quoted command
.CreatedAt - Time when the container was created.
.RunningFor - Elapsed time since the container was started.
.Ports - Exposed ports.
.Status - Container status.
.Size - Container disk size.
.Names - Container names.
.Labels - All labels assigned to the container.
.Label - Value of a specific label for this container. For example {{.Label "com.docker.swarm.cpu"}}
.Mounts - Names of the volumes mounted in this container.
Display containers with their commands
docker ps --format "{{.ID}}: {{.Command}}"
Display containers with their labels in a table
docker ps --format "table {{.ID}}\t{{.Labels}}"
Display containers with their node label in a table
docker ps --format 'table {{.ID}}\t{{(.Label "com.docker.swarm.node")}}'
I built a docker ps pretty print function that can be put into your .bash_profile
or .bashrc
file that works somewhat like an alias for docker ps
(with color output). @art-rock-guitar-superhero suggestions shows how to sort, but I've included this answer since typing the --format
options and piping into a sort
every time is a bit tedious.
function docker () {
if [[ "$@" == "ps -p" ]]; then
command docker ps --all --format "{{.ID}}\t{{.Names}}\t{{.Image}}\t{{.Ports}}\t{{.Status}}" \
| (echo -e "CONTAINER_ID\tNAMES\tIMAGE\tPORTS\tSTATUS" && cat) \
| awk '{printf "\033[1;32m%s\t\033[01;38;5;95;38;5;196m%s\t\033[00m\033[1;34m%s\t\033[01;90m%s %s %s %s %s %s %s\033[00m\n", $1, $2, $3, $4, $5, $6, $7, $8, $9, $10;}' \
| column -s$'\t' -t \
| awk 'NR<2{print $0;next}{print $0 | "sort --key=2"}'
else
command docker "$@"
fi
}
usage: $ docker ps -p
.
EDIT: I added suggestions from the comments from @BrianVosburgh. Also, I kept forgetting to type -p
so I switched the flag for this function to be -a
, which is my regular usage of docker ps
.
If it's enough to simply sort by output column, you can use the following:
docker ps -a --format "table {{.ID}}\t{{.Names}}\t{{.Ports}}" | (read -r; printf "%s\n" "$REPLY"; sort -k 3 )
I also added a code for skipping the table headers and sorting only ps output data.
