Run CopyToRemote once

[yellowhat]

What happened?

Hi,
I would like to upload a folder to a remote host but only once, successive changes to the source should be ignored.

From my understanding ignore_changes should be the option to enable:

remote.CopyToRemote(
    "foo",
    connection=conn,
    source=FileArchive("k8s"),
    remote_path="./",
    opts=ResourceOptions(ignore_changes=["source"]),
)

But I get the following error:

error: command:remote:CopyToRemote resource 'foo': property archive value {<nil>} has a problem: archive must be a path to a file or directory

Any suggestion?

Thanks

Hi @yellowhat, I tried reproducing this, but it worked just fine for me. Are you sure that k8s is a directory or an archive file type like tgz or zip?

Interesting.

• pulumi preview: does not show any error
• pulumi preview --refresh: shows the error above

Oh that clarifies things quite a bit, I can repro this now. Somehow the --refresh option is trying to set state for the source (which it can't do seeing as the archive is something local) and then that nil value is getting into the preview. (and there's some complication with ignoreChanges that makes this worse) Possibly we need to tweak the behavior of read for this resource.

Note that this also fails if you call pulumi refresh and then pulumi preview separately
