+# Creating a Web Server inside Docker
+
+### Start docker and it’s container -
+	```
+	$ systemctl restart docker
+	$ systemctl enable docker
+	$ docker run -it --name webserver centos:latest
+	```
+
+### Install httpd
+- **yum** is already configured in centos docker image.
+So directly install **httpd** software -
+`$ yum install httpd -y`
+
+- Create a dummy web page to check the server -
+	```
+	$ cd /var/www/html
+	$ vi index.html
+	```
+
+### Start services -
+  - If we use **systemctl** to start the services, this will not work and gives an error.
+  - **systemctl** doesn't work in docker.
+  - In actual RedHat system, when we start a service it actually runs a script in background. That script start daemons.
+  - To find the path of that script, check status of service
+`$ systemctl status httpd`
+`Loaded` option shows script file path.
+  - In that file, we have a line which actually starts service -
+`ExecStart = /usr/sbin/httpd....... `
+So the command `/usr/sbin/httpd` actually starts **httpd** server.
+
+- Service is running or not, can be checked by -
+`$ ps -aux | grep httpd`
+
+- So we don't require `systemctl` we can directly start our web server using-
+`$ /usr/sbin/httpd`
+This will start the web server.
+
+- `ifconfig` doesn't work in docker.
+  - So install software, which gives `ifconfig` command.
+  - It can be checked in actual Redhat system by running this command-
+  `$ rpm -qf /usr/sbin/ifconfig`
+  - This comes from **net-tools** package.
+  - So Install **net-tools** in docker os.
+
+- Making _image_ of created web server -
+`$ docker commit webserver apacheimg:v1`
+  - Name of container is _webserver_.
+  - This image can be share with exact setup with other users.
+
+- To save created image -
+`$ docker save apacheimg:v1 -o mywebserver.tar`
+
+- To start **httpd** service automatically when container starts -
+  - Write `/usr/sbin/httpd` in following file.
+	`$ vim /root/.bashrc`
+
+- To copy a file in container from the base system -
+`$ docker cp /root/form.txt  myconatiner:/`
+
+## Summary
+Summary of all the commands -
+```
+$ docker run -it --name webserver centos:latest
+$ yum install httpd -y
+$ rpm -q httpd
+$ cd /var/www/html
+$ vi index.html
+// write some web content
+
+$ /usr/sbin/httpd
+$ yum install net-tool
+
+$ ifconfig
+```
