'What is difference between 'docker ps -all' and 'docker ps -a'?

The command 'docker ps -all' gives me all the created containers but 'docker ps -a' also supposed to give me same results but somehow it returns me only 1 or sometimes 2 latest entries of containers.

Can someone please explain me? I am new to docker. Any help is appreciated.



Solution 1:[1]

As you can see in the documentation -a is just short for --all, they serve the same purpose.

Solution 2:[2]

docker ps -a and docker ps --all are same commands but if you use docker ps -all command it will return just last created container. docker ps -all is same as docker ps -al.
