Description
For variables that are typed (especially complex), one would expect the typing information to be used when formatting via JSON. This is already done correctly in the default table listing.
Given this bake file:
variable "foo_number" {
type = number
default = 11
}
variable "foo_string" {
type = string
default = "11"
}
variable "foo_set" {
type = set(string)
default = ["11"]
}
target "default" {}one would expect to be able to extract the value from the set, but it doesn't work
$ docker buildx bake --list type=variables,format=json --progress quiet | jq 'map(select(.name=="foo_set").value[0])'
jq: error (at <stdin>:17): Cannot index string with number
since the values for all variables (whether complex or not) are output as strings:
$ docker buildx bake --list type=variables,format=json --progress quiet | jq 'map(.value)'
[
"11",
"[\"11\"]",
"11"
]
It's trivial to work around, e.g.,
$ docker buildx bake --list type=variables,format=json --progress quiet | jq 'map(select(.name=="foo_set").value|fromjson)[0]'
[
"11"
]
but it isn't ideal.
I overlooked this while implementing #3207. Fixing this could be considered a breaking change (for those parsing the output and already using a workaround), but it's possible there could be no impact given this has only been out for three weeks. I felt it better to get input prior to submitting a fix.
