To create a Dockerfile for an Nginx image with a customized index.html page, you can follow the example below. This assumes you have your custom index.html file in the same directory as your Dockerfile.
Create a file named Dockerfile with the following content:
[root@siddhesh Build]# cat Dockerfile
FROM nginx:latest
COPY index.html /usr/share/nginx/html/
EXPOSE 80
[root@siddhesh Build]#
This assumes your index.html file is in the same directory as the Dockerfile. If it's in a different directory, adjust the COPY command accordingly.
Now, place your custom index.html file in the same directory as your Dockerfile. For example:
[root@siddhesh Build]# cat index.html
This is test page of builddevops.com
[root@siddhesh Build]#
Then, build the Docker image using the following command:
[root@siddhesh Build]# docker build -t nginx-custom-builddevops .
After building the image, you can run a container based on it with the following command:
[root@siddhesh Build]# docker run -p 443:80 nginx-custom-builddevops
This command maps port 443 on the host to port 80 on the container. You can adjust the port mapping according to your preferences. Now, if you open a web browser and navigate to http://localhost:443, you should see your custom Nginx page.
