container in the first place from scratch. Every tutorial has you<br>
downloading someone's container from somewhere.<br>
<br>
If I wanted to experiment with running let's say a browser within a<br>
container on any OS, where can you go to find out how to build all of<br>
that? At the moment I just spin up VM's but if containers really are a<br>
little lighter on the system than a full VM, I wouldn't mind trying it<br>
out just for browsers.<br>
<br>
It seems to me, though, there's a slight inflexibility in the docker<br>
method versus VM method in terms of updating and/or modifications. For<br>
example, if I create a brand new VM, install a bare OS and then install<br>
the browser, I can possibly go back in later and add something I forgot<br>
(e.g. Java, flash, etc.) just by using the guest OS's install methods.<br>
The new data is merged in right away and the next time I start that VM<br>
those changes are made. My understanding with the Docker method is that<br>
everything has to be installed either in the original image or on the<br>
fly by the docker container script as the image starts but, again, this<br>
is relying on someone else's docker-ready stuff.<br>
<br>
If anyone has pointers on this kind of thing I'd like to see them and<br>
try it out.<br>
