Configuring httpd server on docker container, Setting up Python interpreter and running python code on docker container
I have pre-installed docker container on rhel version_8.0 having docker version docker-3.18
a.) Configuring httpd server on docker container.
- To start the docker engine on rhel8, command: systemctl start docker
2. Pulling a centos image from the docker hub:
3. Launching a new container on the top of the docker engine, command: docker run -it --name web1 centos:latest
Name of the launched OS: "web1", id: "707981bffce3"
4. Now, we will install package name "net-tools" for "ifconfig" command/program, using the command: yum install net-tools -y
5. Now, we will install HTTPD software, using command: yum install httpd -y
6. Now, we will run the command "netstat -tnlp" to check the service has started with default port no:80 or not
As we can see that no service has been started...
7. To start the service httpd, in simple OS, we generally use the command "systemctl start httpd", but it's not in the case of docker, systemctl isn't there in docker.
So, to start the service, we have to run the full path of the full path of the command from where the particular service will start, In this case command: /usr/sbin/httpd
8. Now, again run netstst -tnlp command:
we can see that httpd service has been started..
9. Now, we will create a html file inside /var/www/html folder named "webserver.html"
10. to see the ip of the system, command "ifconfig":
11. Using the curl command from the base OS to check that httpd server has been configured successfully.
b.) Setting up Python interpreter and running python code on docker container
- Again start the same OS with the help of the id
2. Now run the following command to check whether the python is installed or not, and the package is present in the repository or not, command: "yum repolist python3"
3. Now, run the following command to install the python:
4. Now, run the command "python3", to write a program as in live interpreter
5. Now, run a python code, e.g. print("python interpreter installed successfully")
OUR HTTPD SERVER HAS BEEN CONFIGURED SUCCESSFULLY AND PYTHON CODE IS RUNNING SUCCESSFULLY, HERE THE TASK ENDS....
