--set parses number only values as float64

[databus23]

I just noticed that something like helm install --set tag=20161216 ends up in scientific notation in the template and thats because {{ typeOf .Value.tag }} yields float64.

Thats even true for small integers like helm install --set tag=1 --> float64.

This is happening with helm 2.1.0

Does it work differently if you do --set tag=\"1\"?

Thanks to @chancez we know the exact problem: During the conversions to and from JSON done by ghodss/yaml, integers are being cast into float64s to represent Javascript's numeric type. This is causing all integers above a certain value to be represented in scientific notation.

I've been bitten by the same problem. The way of getting over the hump (or the bug) is to do this:

--set bignumber=\\"a185576882739235744\\"

Another workaround we have used is to do stuff like this:

--set port=":1234567"

Then in the template:

{{ .Values.port | replace ":" "" }}

Yuck! 😷
