Fwiw I raised Bug #1240431 a while ago because I also felt that it
wasn't intuitive that the constraints passed when bootstrapping refereed
to the whole environment.

Thanks John and Dimiter. The issue I'm referring to is the one that
John described.
Yeah a solution could be to have separate arguments to set constraints
on bootstrap and on environment. I personally haven't required the
additional environment constraint that you get with 'juju bootstrap
--constraint', and I've always unset it after bootstrapping.

I think his issue is that he can "juju bootstrap --constraints"
and then immediately "juju set-env" to remove the constraints.
But "juju quickstart --constraints" does a bootstrap and then
immediately starts deploying the services without a way to unset
the constraints that don't apply to all machines.
I do think we've talked about wanting to split the "these are the
constraints for the machine I'm bootstrapping" vs "these are the
constraints for the environment within", but we haven't fully
worked through how we would spell that.

Hi Matt,
When you're saying you're unable to clear the constraints set at
bootstrap from the environment, do you mean "tags"
specifically, or
other constraints as well? If the former, but not the latter,
read on.
I've recently discovered there's *no* way to unset a bootstrap (or
environment) constraint value of type list (e.g.
"tags=aa,bb,^cc,dd",
mostly undocumented "networks=..." and since a few days -
"spaces=..."
with the same format). This issue appears to have been lurking
for a
long time - just try this:
$ juju environment set-constraints tags=foo,^bar
$ juju environment get-constraints
tags=foo,^bar
$ juju environment set-constraints tags= # expected: set to
empty
$ juju environment get-constraints
tags=foo,^bar
So, I fixed this on master a few days ago, and in 1.25 it
*will* be
possible to unset list-style constraints (note that, as
before, you
can still set them to different non-empty value).
If your issue is like described above, you might want to give
1.25-alpha1 a try.
Cheers,
