docs: bake: no-cache example is wrong

[MalteMagnussen]

Is this a docs issue?

• My issue is about the documentation content or website

Type of issue

Information is incorrect

Description

The example shows the following: https://docs.docker.com/build/bake/reference/#targetno-cache

[target.no-cache](https://docs.docker.com/build/bake/reference/#targetno-cache)

Don't use cache when building the image. This is the same as the --no-cache flag for docker build.

target "default" {
  no-cache = 1
}

And if I hover the "no-cache" string in visual studio code it says: no-cache optional, number

But the 1 has a red underline. If I hover that, I get:

Unsuitable value type (Unsuitable value: bool required)Docker DX (docker-language-server)

Location

https://docs.docker.com/build/bake/reference/

Suggestion

[target.no-cache](https://docs.docker.com/build/bake/reference/#targetno-cache)

Don't use cache when building the image. This is the same as the --no-cache flag for docker build.

target "default" {
  no-cache = true
}

It seems like there is a clash with the Visual code extension Docker DX (docker-language-server)

If I use "true" instead of "1", then it works just fine. I also think "true" makes more sense than "1".
