python - Container live migration -


i want move running container host host docker. using docker checkpoint create command, , thing creates checkpoints root, , cannot touch them in python. there anyway either force docker create files user, or scp root-made files within python?

when colleague , gave live migration talk , demo @ openstack summit barcelona, used sudo on tar command extract created checkpoint file in /tmp, used ssh/scp host. isn't perfect answer of course still need root permissions access created checkpoint within docker's metadata directory, shows @ least extract 1 root-requiring action separate privileged script, rest of migration requiring "normal" access docker client commands.

you can see our migration script example here: https://github.com/stmuraka/container-migration/blob/master/examples/migrateexample.sh

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
