1. Create a docker apache image using Dockerfile.
2. Create a deploy-vol docker volume.
3. Run a container using docker apacheimg with port forwarding 80:80 and map /var/www/html folder to deploy-vol.
4. Check default apache page is accessible on the browser.
5. Copy/Create a test.html file under /var/lib/docker/volumes/deploy-vol/_data
6. Check on the browser that you are able to access this webpage (test.html)
7. Go inside the container and create a file newtest.html under /var/www/html and verify that you are able to access it with the browser.

Excellent
1. Create a docker apache image using Dockerfile.
-> vi Dockerfile
FROM ubuntu
ENTRYPOINT ["echo"]
CMD ["Hello World"]FROM ubuntu
ARG DEBIAN_FRONTEND=noninteractive
RUN apt-get update
RUN apt-get -y install apache2
ADD . /var/www/html
ENTRYPOINT apachectl -D FOREGROUND
ENV name DEVOPS
-> docker build . -t apacheimg
2. Create a deploy-vol docker volume.
-> docker volume create deploy-vol
3. Run a container using docker apacheimg with port forwarding 80:80 and map /var/www/html folder to deploy-vol.
-> docker container run -dit —name c1 -v deploy-vol:/var/www/html -p 80:80 apacheimg
4. Check default apache page is accessible on browser.
On browser enter: localhost:80 , > Apache2 Ubuntu Default Page running
5. Copy/Create a test.html file under /var/lib/docker/volumes/deploy-vol/_data
-> echo “test text ABC” > /var/lib/docker/volumes/deploy-vol/_data/test.html
6. Check on the browser that you are able to access this webpage (test.html)
-> On browser enter: localhost/test.html , yes
7. Go inside the container and create a file newtest.html under /var/www/html and verify that you are able to access it with the browser.
-> docker exec -it c1 bash
-> echo "Second test page" > /var/www/html/newtest.html
-> On browser enter: localhost/newtest.html , yes
Great Work

2. Create a deploy-vol docker volume.
docker volume create deploy-vol
3. Run a container using docker apacheimg with port forwarding 80:80 and map /var/www/html folder to deploy-vol.
docker container run -it --name c1 -p 80:80 --mount source=deploy-vol,destination=/var/www/html -d apacheimg
4. Check default apache page is accessible on the browser.
curl localhost OR localhost:80 on browser
5. Copy/Create a test.html file under /var/lib/docker/volumes/deploy-vol/_data
vi test.html
h1 hello this is practice /h1
cp test.html /var/lib/docker/volumes/deploy-vol/_data
6. Check on the browser that you are able to access this webpage (test.html)
curl localhost/test.html OR localhost/test.html on browser
7. Go inside the container and create a file newtest.html under /var/www/html and verify that you are able to access it with the browser.
docker exec -it c1 bash
cd /var/www/html
touch newtest.html
echo “h1 this is added, this new test /h1” >> newtest.html
curl localhost/newtest.html OR localhost/newtest.html on browser
