How to sort or order results docker ps --format?

Question

I haven't found any way to order my results when using docker ps

In my case I want to order by .Ports

docker ps -a --format "table {{.ID}}\t{{.Names}}\t{{.Ports}}"

How do I order the result?

Answer 1

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.
