good job
Delete1. Create a container with an ubuntu image
var/www/html
Delete-> docker container run -dit --name con2 -p 80:80 ubuntu
2. update the repository (apt update -y) in the container
-> docker exec -it con2 bash
-> apt update -y
3. install apache2 in a container ( apt install apache2 -y)
-> apt install apache2 -y
4. Create a directory config under /config in the container
-> mkdir config
5. Add web.config file under /config folder
-> touch /config/web.config
6. copy an html file from your host machine to container /var/www/html
-> exit
-> echo "abc" >> TEST.html
-> docker cp TEST.html con2
-> docker exec -it con2 bash
7. Verify your container is able to browse your html file (curl localhost) ( To install the curl apt install curl)
-> apt install curl
-> curl localhost/TEST.html
8. Create a production image (prod/webapp)
-> docker commit con2 webserverimg
-> docker images
9. remove all the containers ( docker rm -f $(docker ps -a -q)
-> docker rm -f $(docker ps -a -q)
10 create a new container with prod/webapp with 80 container port forwarding and verify you are able to access the website and in the container /config directory exist with web.config file
-> docker container run -dit --name con2 -p 80:80 webserverimg
-> docker exec -it con2 bash
-> service apache2 start
On web browser, go to: localhost/TEST.html
