mkdir -p /myweb

cd /myweb

echo "hello world" > index.html

docker run -itd --name myweb1 -p 8080:80 httpd

docker run -itd --name myweb2 -v /myweb: docker run -it --rm busybox:latest echo "hello" -p 8080:80 httpd

docker run -itd --name myweb2 -v /myweb:/usr/local/apache2/htdoc -p 8080:80 httpd

docker run -itd --name myweb3 -v /myweb:/usr/local/apache2/htdoc -p 8080:80 httpd

docker exec -it myweb3 bash

cd htdoc

cat index.html

exit

docker rm -f myweb3

docker run -itd --name myweb3 -v /myweb:/usr/local/apache2/htdocs -p 8081:80 httpd
