I'm new to docker. I tried executing the following docker command to created a container,
docker run -d -p 9999:80 httpd
After this, when i visited the URL http://127.0.0.1:9999/, It loads with "It works!" message. So, to change the message, I went inside the httpd container and changed the value of /usr/local/apache2/htdocs/index.html (Hope, that is the correct location) to <html><body><h1>It works at port 9999!</h1></body></html>.
But still it is showing the same old message and the weird part is it is still showing up after removing the container. Am i doing anything wrong or is this coming from any cache or something?
Please help.
Edit: I found it is due to browser cache and nothing else.
You did a modification to a running container, but if you want to see it, you have to
docker commit -t my_apache_modifiedyour container, and then launch your new image, with a
docker run -d -p 9999:80 my_apache_modifiedsee the doc
https://docs.docker.com/reference/commandline/commit/
Keep in mind that the preferred way is to modify your Dockerfile, and build a new image
I can't reproduce your error here.
Try that:
And try to see in your browser. (http://127.0.0.1:9999)
