This makes a confined setting where by the method simply cannot entry data files outside its new “root” directory.
As we appear to comprehend more details on how container isolation works, We are going to begin to see how these levels might be manipulated to suit diverse situations. We will also check out how we can easily use normal Linux get more info tooling to communicate with Individuals layers and troubleshoot container security problems.
