Hello everybody. Today we are going to
continue this docker course.


So let's talk about class 3, which will
be installing servers in Docker. So come


on. Show the points
we are going to talk about today.


Let's start the content,
remembering that we have other classes


that explain how to start a
container and today we will show you


how to install an APACHE server inside
a container and we will access this APACHE


using the host machine and we will
start another


container and also access this Apache
server . The objective


of the class is to get a server
working inside a container and


show that it is also accessed
by both the host machine and other


clients. And then we will
create an image of this container with


the server because then you
can use this image to raise


container instances. This way, you will already have the server
installed. So let's go


ah yes ... there is a
question from our friend ...


he is asking ... If you
have used the servers in the docker? So


if you've used servers in Docker,
pause and comment if you've already used them.


And also what have you been finding about the use of
docker servers. So come


on, start a
container. So to start a container


we've already learned in another class.
Let's start a container here in the


background, let's name it
my_webserver and it will be with the


debian image and then we'll access
this container. So let's


access sudo docker run here...


We've already started here the
container is already in the background. Now


let's run this container


OK, we're inside the
container and let me see what I


prepared here for you...
Now let's install


APACHE for that
let's update and let's use


apt-get update
then let's apt- get install apache2 net-tools


...
net-tools to get access to


ifconfig and netstat. So let's go
to the terminal here.


Ok, the update is done
Now let's go to the next step


...


apt-get install apache2 net-tools


You agree
Ok finished the installation and we


also have videos about APACHE
both running http and also


installing https. I'll leave it
here on the card and I'll also put it in the


description. Here we are
installing apache in a simple way just


for us to show it in Docker.
So come on, we've already installed it and let's


check it out by starting the
server. service apache2 start


It was ok here it is already
started. So we can check...


how do we install net-tools
let's check


netstat -anlt | grep :80
...


...
I'm checking port 80 here


using the netstat command so
we can see it's already listening on port 80.


Ok, so now we
can do a test... Let me see what's going on


prepared here...
to do the test we will


use the browser, for example, on
the real machine. It is


important to identify what the IP of this
container is. So here it already


informs when APACHE got up it
informed here what the IP was. If by chance you


didn't see this moment when it was
shown The IP can give ifconfig


...
And here you will see the IP that


the container is using. So, let's
raise a Firefox on the host machine here


...
172.17.0.2


and ready here we are already accessing the
container's Apache. Beauty very well.


Let me see the next step here...
Now we are going to access Apache


using another container. So let's go
with another container.


So let's leave this container
even leaving this continues because it


is running in the background and we will
start another container here


sudo docker -it will go
straight into the container has for


us to do and we will call
the client container


and will use the Alpine have to
Cause it's lighter


...


Ok, we're inside the
client so here we can give an


ifconfig to see the client's IP
which is the end 0.3. So


let's access the server there.
Remembering that on the final server the IP was 0.2


Let's use wget 172.17.0.2


Ok we downloaded the page
index.HTML. To Dalbert I want to see this


page. You can take a
cat index.html


And you see the page there
And here we have the beginning of the page


Ok , let's see the next
step here. Now we're going to create a


docker image of your server. Then
we're going to use the COMMIT we


've already seen in the image creation class. I'll
leave the Card here. let's go


to COMMIT
Let's get out of this container which in this case


giving an EXIT will turn it off.
sudo docker commit


And the container
I'm trying to generate the


image. So it's my_webserver and the image
name ... here


we could give a name referring to the
use of Debian and for


Apache .... we could
put something like debian_apache


debian_apache_img
...


Ok, it was generated and let's see sudo there
docker images and ready here is our


image. So from
this image I can lift the


apache container lift whenever
I want.


Let's see here...
Ok, comment there if you liked it or if you have


any questions. In the next class I
would like you to choose the topic


we can put docker network types.
Then show some types of networks that exist


and how to use networks in Docker. Or we could see
more about servers in Docker letter B.


And letter C would be transferring
files in docker. So tell me


what you want to see in the next
class on Docker. see you


all
