This adds a new series of "get*" functions which can read values from
the associated "value" resources. The key name of the function must
match the name value of the resource for things to work.
Type unification isn't yet perfect in these scenarios, so you should use
casually and with caution.
It's valuable to check your runtime values and to shut down the entire
engine in case something doesn't match. This patch adds some magic
plumbing to support a "panic" mechanism.
A new "panic" statement gets transparently converted into a panic
function and panic resource. The former errors if the input is not
empty. The latter must be present to consume the value, but doesn't
actually do anything.
This is a strange resource which is probably most useful for passing
values between scopes. It supports a variant resource field, and should
only be used as a last resort and if you know exactly what you're doing.
This adds a meta state store that is preserved between graph switches if
the kind and name match. This is useful so that rapid graph changes
don't necessarily reset their retry count if they've only changed one
resource field.
There were some bugs about setting resource fields that were structs
with various fields. This makes things more strict and correct. Now we
check for duplicate field names earlier (duplicates due to identical
aliases) and we also don't try and set private fields, or incorrectly
set partial structs.
Most interestingly, this also cleans up all of the resources and ensures
that each one has nicer docs and a clear struct tag for fields that we
want to use in mcl. These are mandatory now, and if you're missing the
tag, then we will ignore the field.
Hetzner cloud resource using hcloud-go. Requires polling via Meta:poll param. This first commit provides a stable vm resource with support for the basic functions of creating, deleting and updating a live server instance. SSH key handling does still require some attention to make sure checkapply can detect and update live changes to the specified keylist. A dedicated hetzner:sshkeys resource might be in order to make sure the keyset is handled correctly if there are multiple hetzner:vm resources running under the same Hetzner project. All remarks for future improvements are indicated with a TODO prefix
There were a bunch of packages that weren't well documented. With the
recent split up of the lang package, I figured it would be more helpful
for new contributors who want to learn the structure of the project.
The old system with vendor/ and git submodules worked great,
unfortunately FUD around git submodules seemed to scare people away and
golang moved to a go.mod system that adds a new lock file format instead
of using the built-in git version. It's now almost impossible to use
modern golang without this, so we've switched.
So much for the golang compatibility promise-- turns out it doesn't
apply to the useful parts that I actually care about like this.
Thanks to frebib for his incredibly valuable contributions to this
patch. This snide commit message is mine alone.
This patch also mixes in some changes due to legacy golang as we've also
bumped the minimum version to 1.16 in the docs and tests.
Lastly, we had to disable some tests and fix up a few other misc things
to get this passing. We've definitely hot bugs in the go.mod system, and
our Makefile tries to workaround those.
docker/client.NewClient() is deprecated in favour of NewClientWithOpts()
which takes a series of client.Opt functions to configure the API
client. As mgmt only passes the API version through, this simplifies the
NewClient() calls.
