02/24/2019, 4:44 PMGot it. Sounds like 400 == o620 is technically a legal value according to Kubernetes. - w
white-balloon-205
02/24/2019, 4:44 PMOptional: mode bits to use on created files by default. Must be a value between 0 and 0777. Defaults to 0644. Directories within the path are not affected by this setting. This might be in conflict with other options that affect the file mode, like fsGroup, and the result can be other mode bits set.

02/24/2019, 4:44 PMyeah, but its completely NOT transparent - w
white-balloon-205
02/24/2019, 4:45 PMI think that’s just how kubernetes handles this though, right? - l
little-river-49422
02/24/2019, 4:45 PMno, with kubernetes i just type 400 and it doesnt cast it to 620 🙂 - w
white-balloon-205
02/24/2019, 4:47 PMOh - is that really true, the kubernetes api accepts an integer, not a string, in decimal and then automatically reinterprets it as octal? - l
little-river-49422
02/24/2019, 4:47 PMi have no idea 🙂 I'm not any good with go, so I cant even look it up - l
little-river-49422
02/24/2019, 4:47 PMbut kubernetes accepts integer, not string - l
little-river-49422
02/24/2019, 4:47 PMand somehow interprets it as 400 - l
little-river-49422
02/24/2019, 4:47 PMnot 620 🙂 - w
white-balloon-205
02/24/2019, 4:48 PMWell, if the same integer value passed to Pulumi results in a different API representation than in a yaml file, that is definitely a bug. But this sounds surprising. - w
white-balloon-205
02/24/2019, 4:50 PMDocs here for example seem to make clear that this is accepted as decimal since there is not support for octal literals in json: https://kubernetes.io/docs/concepts/configuration/secret/ - w
white-balloon-205
02/24/2019, 4:50 PMNote that the JSON spec doesn’t support octal notation, so use the value 256 for 0400 permissions. If you use yaml instead of json for the pod, you can use octal notation to specify permissions in a more natural way.

little-river-49422
02/24/2019, 4:50 PMyeah, so this is where confusion comes from - l
little-river-49422
02/24/2019, 4:51 PMits trying to be smart, since json doesnt support octal - w
white-balloon-205
02/24/2019, 4:52 PMI don’t think anything is trying to be smart. This is an integer value. You can pass it as a decimal literal or as an octal literal. But it’s just an integer value to kubernetes. No one is doing any conversion of it - not kubernetes, not Pulumi. They’ll just take the integer you provide and use that. - l
little-river-49422
02/24/2019, 4:53 PMsure, but this is completely different to yaml - l
little-river-49422
02/24/2019, 4:53 PMno one is using json to create kubernetes primitives, really - w
white-balloon-205
02/24/2019, 4:56 PMYou mean that yaml has octal literals? You can’t pass
in yaml either. what you can presumably pass is400
. I assume in Python you can pass0o400
as well?0400 - l
little-river-49422
02/24/2019, 4:56 PMno, in yaml you just do 400 - l
little-river-49422
02/24/2019, 4:57 PMm, in my case you do 0400 - w
white-balloon-205
02/24/2019, 4:57 PMI really don’t think so. See the yaml example of using default mode in the link I shared above. - l
little-river-49422
02/24/2019, 5:03 PMits 0400 - l
little-river-49422
02/24/2019, 5:04 PMi think its yaml for octal - h
helpful-vegetable-35581
02/24/2019, 5:08 PMLeading 0 is octal in yaml - w
white-balloon-205
02/24/2019, 5:08 PMI believe Yaml supports both
and0o400
as octal literals. I believe python support0400
for octal literals. (Though there is a proposal to deprecate this and require0400
?) I believe JavaScript now only supports0o400
for octal literals (the0o400
form was recently deprecated). Json does not support octal literals.0400 - l
little-river-49422
02/24/2019, 5:09 PMno, for python 0400 only works in 2.x i think, in 3+ they force 0oxxx - w
white-balloon-205
02/24/2019, 5:10 PMAhh - yes - that makes sense. Similar to Javascript. So
is supported in YAML/Python/JavaScript.0o400 - l
little-river-49422
02/24/2019, 5:11 PMyeah, i think this confusion comes from yaml files, nevertheless - l
little-river-49422
02/24/2019, 5:11 PMi have lots of them with 420, for example
