Support Elastigroup for all commands
Some command line options don't work with Spotinst Elastigroups, only native Auto Scaling Groups.
The commands that seem to work:
- create
- list
- domains
- dump
- events
- health
- images
- resources
- traffic
- update
- scale - Implemented in #525
- patch - implemented in #530
- respawn-instances - implemented in #530
- instances - implemented in #547
- status - implemented in #554
The commands that still don't work or don't offer Elastigroup:
- init - no knowledge about Elastigroups
@lmineiro @pc-alves are there any plans on adding support for the instances command to work with ElastiGroup?
The current workaround is to use the --all flag and grep for your specific application. For example:
senza instances --all | grep myapp
Hopefully gives you the same as:
senza instances myapp
This will eventually be implemented, but since there's a reasonable workaround it doesn't have a high priority currently
@lmineiro thanks for answering. Reason why I'm asking is that the workaround you mentioned sometimes is quite slow. It takes up to 20sec to run senza instances --all when running from office network and one of my colleagues noticed this time to grow up to 40sec when running from home. At the same time running senza inst $APPLICATION never takes longer than a couple of seconds.
According to my own experiments, the time the command takes, even without --all, varies a lot and can be very slow at times.
My test using the stack reference:
$ time senza instances skipper
Stack Name│Ver.│Resource ID│Instance ID │Public IP │Private IP │State │LB Status│Launched
<28 instances listed>
real 0m23.177s
user 0m2.429s
sys 0m0.265s
Followed almost immediately by the same query with --all
$ time senza instances skipper --all
Stack Name│Ver.│Resource ID│Instance ID │Public IP │Private IP │State │LB Status│Launched
<the same 28 instances listed>
real 0m15.200s
user 0m2.342s
sys 0m0.244s
As you can see, both are very slow, and using the stack reference was even slower for me.
The proposed workaround is exactly that - just a workaround until we're confident that something like https://github.com/zalando-stups/senza/pull/547 is an acceptable solution.
@lmineiro thank you for the explanation. Then I guess we'll stick to the workaround until senza gets updated
@lmineiro done. It works. Thanks a lot for implementing this :smile:
