Useful Docker Commands for Beginners

Hi Everyone, 

Being a newbie to docker, I thought of sharing some useful commands running docker. 

1. List the images
   

   sudo docker image ls

   
   
2. List the running containers
   

   sudo docker container ls

   
   
3. Build and tag a docker image
   

   sudo docker build -t <name_of_the_image> . 

   
   
4. Run a docker image
   

   sudo docker run -p 8888:8080 <name_of_the_image>

   
   
5. Check the java version running on a container
   
   First list the containers using

   sudo docker container ls

   Then execute the following command to check the running java version of the container. You have to use the container id obtained from the previous output.
   

   sudo docker exec <container_id> java -version

   
   
6. Delete Container
   

   sudo docker container rm <container_id>

   
   
7. Delete Image
   

   sudo docker image rm <image_id>

Hope it helps.

Thanks.
