Hi i am new user on ubuntu during my practice i install docker by

sudo apt install docker.io

Check the version and all thing properly i started working after it i pull the ubuntu image by

sudo docker pull ubuntu

after it i check the image by

sudo docker images

image is shown by all details after that i make the container by

sudo docker container run -it ubuntu /bin/bash

when i try to see my container by

sudo docker ps

the result is blank 

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

But when i write this command

sudu docker ps -a

this shows me the container

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                    PORTS               NAMES
110359388f2d        ubuntu              "/bin/bash"         21 hours ago        Exited (0) 21 hours ago                       stupefied_dewdney

How to fix this? Why my container is not showing in docker ps ?

So there is a difference between docker ps and docker ps -a

docker ps: shows the running container on your host
docker ps -a: this shows running and exited containers on the host.

So in your case your container is exited, means not running on the host thats why this shows in docker ps -a

It's not showing as the container has exited.

docker ps only shows running containers while passing the -a flag shows all containers. If you want your container to show up, you will have to start it by using docker container start

    if container has single command it will stop and again `docker ps` will show nothing – d0niek Feb 12 '20 at 12:37
