[slack-digest] [2019-03-13] #general
2019-03-13 01:12:40 UTC - Sam Hjelmfelt: Thanks @Dave Grove! That is in the same ballpark as what I have seen with Docker+YARN. I am hoping to run some tests with native YARN containers (no docker) in the next week or two.

2019-03-13 01:14:17 UTC - Sam Hjelmfelt: For context, here is a presentation from Microsoft in 2017 about their YARN clusters: <https://www.slideshare.net/Hadoop_Summit/lessons-learned-from-scaling-yarn-to-40k-machines-in-a-multi-tenancy-environment>
Cluster size: 4,000 nodes
Sustained load: less than 3000 QPS
Allocation/Promotion latency @ 95th percentile: less than 3s
Rack locality: 99.84%

----
2019-03-13 05:33:33 UTC - Dominic Kim: FWIW, it would be a good time to test the recent docker versions, HDYT?
https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552455213246900
----
2019-03-13 07:35:05 UTC - Sven Lange-Last: yes, i’m aware of the vulnerability above. ibm cloud functions addressed it by updating to a later docker version.

----
2019-03-13 07:35:30 UTC - Sven Lange-Last: we know that ow runs with docker 18.06.
https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552462530248900
----
2019-03-13 07:36:20 UTC - Dominic Kim: @Sven Lange-Last oh does `DOCKER_VERSION=1.12.0` client compatible with `18.06`?
https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552462580249400
----
2019-03-13 07:37:59 UTC - Markus Thömmes: AFAIK travis has been running on a newer docker version for ages
https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552462679249800
----
2019-03-13 07:38:12 UTC - Markus Thömmes: see <https://github.com/apache/incubator-openwhisk/issues/3291>

----
2019-03-13 07:39:14 UTC - Sven Lange-Last: yes, docker client 1.12 works properly with docker 18.06 on the server side.
https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552462754251100
----
2019-03-13 07:39:17 UTC - Dominic Kim: I thought 1.12 only compatible with <= 17.05
https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552462757251300
----
2019-03-13 07:39:21 UTC - Dominic Kim: oh..
https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552462761251500
----
2019-03-13 07:39:28 UTC - Dominic Kim: ok thanks I will try.
https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552462768251800
----
2019-03-13 07:39:51 UTC - Markus Thömmes: quite importantly though, the runc binary won't be compatible
https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552462791252700
----
2019-03-13 07:40:12 UTC - Dominic Kim: @Markus Thömmes so I need to disable runc with 18.06
https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552462812253400
----
2019-03-13 07:40:22 UTC - Markus Thömmes: most likely, yes
https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552462822253800
----
2019-03-13 07:40:28 UTC - Dominic Kim: got it :thumbsup:
https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552462828254100
----
2019-03-13 07:40:43 UTC - Sven Lange-Last: well, it probably depends on certain `docker` subcommands and options. but for most of the stuff we are doing with `docker`, it works fine. @Dave Grove introduced a new option on `docker run` that was renamed with a later `docker` cli version.

----
2019-03-13 07:41:09 UTC - Markus Thömmes: let's debate updating the docker version in the invoker though. What's stopping us from advocating a much more recent version of docker in the invoker?
+1 : Dominic Kim, seonghyun
https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552462869255100
----
2019-03-13 07:41:36 UTC - Sven Lange-Last: no technical reasons that stop us from updating.

2019-03-13 07:43:40 UTC - Dominic Kim: +1 on updating : )

2019-03-13 07:45:41 UTC - Markus Thömmes: @Dominic Kim want to open a dev list thread asking if anybody would be broken by this?
https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552463141256900
----
2019-03-13 07:47:42 UTC - Dominic Kim: @Markus Thömmes sure
https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552463262257200
----
2019-03-13 07:58:17 UTC - Dominic Kim: I quickly looked through issues and it seems there's no issue relevant to updating docker version.
https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1552463897257900
----
2019-03-13 07:58:45 UTC - Dominic Kim: So I will create a new one and share it via dev list. If I miss the existing one, kindly let me know.
