Docker series (Part 2): Starting an nginx Web server on Ubuntu

Let's type this in our terminal to run a nginx web server

sudo docker container run --publish 80:80 nginx

go to your browser and type "localhost". You can see a page of nginx.

This is what basically happened

Stop the container using Ctrl+C

Now, it is not active any more.

Let's create another one and this time , we will run it in the back ground.

sudo docker container run --publish 80:80 --detach nginx

This detach command actually runs it in the background and after we run it, we get a container ID

again, you can go to your browser and type "localhost" and see the nginx server.

now go to the terminal and type

sudo docker container ls

This shows which container is running.

Let's stop it

sudo docker container stop <1st few digits of the container id>

So, it has been stopped.

Now, let's see how many containers we actually created because we stopped them but not deleted them ever.

sudo docker container ls -a

You can also go to your VS Code studio and install "Docker" from extensions . This will also track how many containers etc are there

also, you can see some unique name here like "elastic_saha"", "elastic_newton". This was randomly provided as you did not provide them.
Let's provide them a name and create another container .

sudo docker container run --publish 80:80 --detach --name mitul_shahriyar nginx

Your VS code will look like this

You can go to your browser & type for "localhost" to see a nginx server.

let's see all the container list again

sudo docker container ls -a

let's see some logs of this container which we gave the name "mitul_shahriyar"

Also , you may know commands to run docker or play with

Now, lets remove them

sudo docker container rm <1st few digits of container id>

We have 1 container running which we will forcefully remove

I imagine the only commands that need sudo are those where you're binding to a port below 1024. All the other ones should be run as a regular user.
