----------------------------------------
Summary: Rename maintenance commands to have a consistent prefix
Key: AURORA-43
URL: https://issues.apache.org/jira/browse/AURORA-43
Project: Aurora
Issue Type: Task
Components: SRE
Reporter: Tobias Weingartner
Priority: Trivial
Let's make the drain/maintenance commands have a common prefix, preferably
something short. I propose the following in a man page format:
{noformat}
SYNOPSIS
drain_status [-f filename] cluster [host ...]
drain_script [-f filename] [-s N] [-b function] cluster script [host ...]
drain_mark [-f filename] cluster [host ...]
drain_start [-f filename] cluster [host ...]
drain_end [-f filename] cluster [host ...]
DESCRIPTION
drain_status
Print the drain status of each supplied host.
drain_script
Perform a fully scripted drain cycle. This includes doing the equivalent
of doing a 'drain_start' for each batch, and once the batch is drained,
running the given script file with the input being the list of hosts within
the current batch. After the script exits successfully, 'drain_end' will be
run on the current batch before moving on to subsequent batches.
If the script returns a non-zero exit status, the full operation is aborted.
drain_mark
The list of hosts is marked for maintenance, and will be de-prioritized
from consideration for scheduling. Note, they are not removed from
consideration, and may still schedule tasks if resources are very scarce.
Usually you would mark a larger set of machines for drain, and then do
them in batches within the larger set, to help drained tasks not land on
future hosts that will be drained shortly in subsequent batches.
drain_start
The list of hosts is drained and marked in a drained state. This will kill
off any tasks currently running on these hosts, as well as prevent future
tasks from scheduling on these hosts while they are drained.
drain_end
The list of hosts is marked as not in a drained state anymore. This will
allow normal scheduling to resume on the given list of hosts.
OPTIONS
-f, --file filename
Provide a filename (you can specify stdin using "-") containing the list of
hosts to perform the given action on. No hosts performs nothing.
-s, --size N
Give the size of each batch done in parallel during the drain_script.
-b, --by function
Give a function to specify the type of grouping you wish to happen.
