![4. Thus, to check the status of the container, you can run:
$sudo docker ps
5. Then to stop the running container run:
$sudo docker stop [name-of-the-container-running]
To remove the container :
$sudo docker rm [name-of-the-container-to-be-removed]](https://image.slidesharecdn.com/webappusingdockercontainer-200528115126/85/Webapp-using-docker-container-11-320.jpg)
Webapp using docker container
- 1. WEBAPP USING DOCKER CONTAINER Id no: 16CP024 16CP031
- 2. WHAT IS DOCKER? Docker is a set of platform as a service products that uses OS-level virtualization to deliver software in packages called containers. Precisely, it is open platform for developing, shipping, and running applications. Assembling above definitions, Docker is an operating system container management tool that allows you to easily manage and deploy applications by making it easy to package them within operating system containers.
- 3. TO UNDERSTAND DOCKER, THUS WE MUST FIRST UNDERSTAND CONTAINER Containerization is the process of packaging an application along with its required libraries, frameworks, and configuration files together so that it can be run in various computing environments efficiently. In simpler terms, containerization is the encapsulation of an application and its required environment.
- 4. As containers and virtual machines are many a times used interchangeably, to know the difference between them becomes important.
- 7. WORKING WITH DOCKER To start with docker, firstly, you need to install docker in your system through any of the three ways prescribed in the below link. https://docs.docker.com/engine/install/
- 8. TO RUN NGINX IN A DOCKER CONTAINER ON UBUNTU Nginx is an open source reverse proxy server for HTTP, HTTPS, SMTP, POP3, and IMAP protocols, as well as a load balancer, HTTP cache, and a web server (origin server). So, let’s try to run our first webpage using nginx. 1. To get the nginx image in the system, run the below command. $sudo docker pull nginx 2. To start this container, $sudo docker run --name docker-nginx -p 80:80 -d nginx where –d is used to run the image in background. Note: As we are working with the ubuntu platform “sudo” must be used before every command otherwise with Windows or mac no need of using ”sudo”.
- 10. 3. Paste the IP address of your Ubuntu system into a web browser and you should see Nginx’s “Welcome to nginx!” page.
- 11. 4. Thus, to check the status of the container, you can run: $sudo docker ps 5. Then to stop the running container run: $sudo docker stop [name-of-the-container-running] To remove the container : $sudo docker rm [name-of-the-container-to-be-removed]
- 12. TO CREATE YOUR OWN WEBPAGE IN NGINX: 1. Create a new directory within your home directory and hence create a “index.html” file within it (this is the webpage you want to create). $mkdir -p ~/docker-nginx/html $cd ~/docker-nginx/html $vim index.html 2. Now, to start the container run the below command: $sudo docker run --name docker-nginx -p 80:80 –d –v ~/docker- nginx/html:/usr/share/nginx/html nginx this command tells the system to look for the webpage in the prescribed location rather than the default one.
- 14. TO RUN YOUR WEBAPP UPLOADED ON GITHUB USING DOCKER Link your docker with the repository on your github through docker hub. Then login to your docker account by: $sudo docker login Open and run your repository using : $ sudo docker push USERNAME/appname Hence, with the ip-address see your webapp running..
