Is there a (better!) way to cache only one line of a .WithExec() container?

[opaque sleet]

I am checking out a repo and it was cached as the repo URL remains the same between runs.
I am using this as a previous step:
WithEnvVariable("CACHE_BUSTER", fmt.Sprintf("%d", time.Now().Unix())).

To make sure the following steps are not cached. Is there a better way?

@past siren are you trying to make sure the latest git commit for a given git branch or tag is always pulled?

Wrong Ben :p

[hybrid fossil]

oh no sorry!!

are you trying to make sure the latest git commit for a given git branch or tag is always pulled?

That's a solid approach in general.
But if you're using the WithExec() to call git, you could use theGit core function instead with head /branch and tree.

what you were thinking @hybrid fossil ? 👆

[hybrid fossil]

yeah normally if you use core git API, you don't need cache buster. But I'm thinking maybe they execute git in a container?

[tardy berry]

yep, they mention WithExec so assume were doing in a container, showing Git alternative.
