Docker HUB

docker hub is the place where the repositories live , just like GIT .

Git store code , docker hub store images!

first go to Docker Hub and create a account .

nothing special just fill the form and confirm your email.

after login we will redirected to this home page

We can see our alpine Official Image that we used in last part

we can see 1+ billion download amazing!

to pull the image simple docker pull alpine and voila! we have an image ready to use locally!

We also have tags tab

basically tags are versions to the image we can download the version we like.

Official and Trusted

verified publisher is well known company that publish it's own docker like IBM

official is like the ubuntu company publish there own docker image

---

Unofficial Images

I like to mention that free docker account , can use only 1 private docker image but unlimited public docker images!

let's take a look for an unofficial docker image.

let's take a look at sarahlaw007 image

We can notice that the username is before the image name ? Why alpine doesn't have one?

Simply because alpine is an official image so no need to username , it's hidden.
