Reference guide for Docker Commands — NEW v/s OLD — LinuxTechLab

So I have been using Docker on & off for quite some time now, so when I started using Docker in 2016, I learned about it a bit & I learned about the Docker commands & I was quite comfortable with it. Then my role got changed & I was not using Docker anymore at all. Forward to 2018, I started using it again, but some things were changed with the way commands in Docker worked. Whenever I would reference a document, the commands were a bit changed, they were somewhat different.

Though their corresponding old commands would still work but Docker did introduce some changes & i believe those were welcomed changes. But it did create some confusion for me for a short while, some others might be confused with the old commands and new commands. I know most will say that these are not new commands as the change happened quite some time ago but still I thought of writing this article.

This article will work as a reference for old Docker commands & their replacement, the new & improved Docker commands. So earlier commands would be called like,

# docker command options

For example,

Now they are mentioned like.

# docker command sub-command option

For example,

# docker container run image-id

Now we will discuss some other important commands that got an upgrade & will also discuss some newly introduced commands in Docker.

The way this will work is, I will first mention the old command and then will mention the new command followed by a brief about the command, like, # OLD_COMMAND — NEW_COMMAND — Brief introduction of command

So let’s get going.

Docker Commands

Then there are some new commands introduced as well related to Docker Networking.

Docker Networking Commands

I have tried to cover all the important commands that we use, but in case I have missed something (which I am sure I have ) or have added something wrong or you have any query or questions regarding this tutorial, then you can write to us using the comment box below.
