It turns out that `d.GetOk` also returns `false` when the user _did_ actually supply a value for it in the config, but the value itself needs to be evaluated before it can be used.
So instead of passing a `ResourceData` we now pass a `ResourceConfig`
which makes much more sense for doing the validation anyway.
The tests did pass, but that was because they only tested part of the changes. By using the `schema.TestResourceDataRaw` function the schema and config are better tested and so they pointed out a problem with the schema of the Chef provisioner.
The `Elem` fields did not have a `*schema.Schema` but a `schema.Schema` and in an `Elem` schema only the `Type` field may (and must) be set. Any other fields like `Optional` are not allowed here.
Next to fixing that problem I also did a little refactoring and cleaning up. Mainly making the `ProvisionerS` private (`provisioner`) and removing the deprecated fields.
1. Migrate `chef` provisioner to `schema.Provisioner`:
* `chef.Provisioner` structure was renamed to `ProvisionerS`and now it's decoded from `schema.ResourceData` instead of `terraform.ResourceConfig` using simple copy-paste-based solution;
* Added simple schema without any validation yet.
2. Support `ValidateFunc` validate function : implemented in `file` and `chef` provisioners.
Storing error values to atomic.Value may fail if they have different
dynamic types. Wrap error value in a consistent struct type to avoid
panics.
Make sure we return a nil error on success
If the shell spawns a subprocess which doesn't close the output file
descriptors, the exec.Cmd will block on Wait() (see
golang.org/issue/18874). Use an os.Pipe to provide the command with a
real file descriptor so the exec package doesn't need to do the copy
manually. This in turn may block our own reading goroutine, but we can
select on that and leave it for cleanup later.
Fixes#10788
This checks `IsComputed` prior to attempting to use the JSON
configurations. Due to a change in 0.8, the prior check for simply map
existence would always succeed even with a computed value (as designed),
but we forgot to update provisioners to not do that.
There are other provisioners that also do this but to no ill effect
currently. I've only changed Chef since we know that is an issue.
This issue doesn't affect 0.9 due to helper/schema doing this
automatically for provisioners.
The provisioner collected all inline commands into a single script which meant
only the exit code of the last command was actually checked for an error.
* provisioner/chef: Support named run-lists for Policyfiles
Add an optional argument for overriding the Chef Client's initial
run with a named run-list specified by the Policyfile. This is useful
for bootstrapping a node with a one-time setup recipe that deviates
from a policy's normal run-list.
* Update chef client cmd building per review feedback.
Fixes#10463
I'm really surprised this flew under the radar for years...
By having unique PRNGs, the SSH communicator could and would
generate identical ScriptPaths and two provisioners running in parallel
could overwrite each other and execute the same script. This would
happen because they're both seeded by the current time which could
potentially be identical if done in parallel...
Instead, we share the rand now so that the sequence is guaranteed
unique. As an extra measure of robustness, we also multiple by the PID
so that we're also protected against two processes at the same time.
Fixes#3605 and adds the functionality suggested in PR #7440.
This PR is using a different appraoch that (IMHO) feels cleaner and (even more important) adds support for Windows at the same time.
- Include new option in file provisioner. Now content or source can be
provided. Content will create a temp file and copy there the contents.
- Later that file will be used as source.
- Include test to check that changes are working correctly.
The script cleanup step added in #5577 was positioned before the
`cmd.Wait()` call to ensure the command completes. This was causing
non-deterministic failures, especially for longer running scripts.
Fixes#5699Fixes#5737
See the updated docs for more details and examples, but in short this
enables the `attributes` param from the Chef provisioner to accept a
raw JSON string.
Fixes#3074Fixes#3572
PR #3896 added support for passing keys by content, but in this same PR
all references to `path.Join()` where changed to `filepath.join()`.
There is however a significant difference between these two calls and
using the latter one now causes issues when running the Chef
provisioner on Windows (see issue #4039).
Builds on the work of #3846, shifting the Chef provisioner's
configuration options from `secret_key_path` and `validation_key_path`
over to `secret_key` and `validation_key`.
This Adds three new arguments `use_policyfile`, `policy_group` and `policy_name` to the Chef
provisioner. If `use_policyfile` == true, then the other arguments are required.
Still not a 100% fix, but that would require some more hacking in core
TF. If time permits I’ll have a look at that later on… But for now this
is a good fix to be able to close#2872
