Fixed the result unwrapping issue while also improving how and where the profile gets loaded.

This looks good to me - with the caveat that I am not very familiar with this code. But updated code looks logical, and maybe most importantly, all tests are passing.

zmrow

As an aside, if you're not already doing so it'd probably be good to run down the entire set of pubsys commands in your own account, making sure that the grant/revoke and SSM params all work as expected. Those are super important.

+    let maybe_regional_role = aws.region.get(&region).and_then(|r| r.role.clone());
+    let config = if maybe_regional_role.is_some() {


I'm confused about this let config... are we replacing the config we just built?

Correct, but I can rename it to make it more clear.

jpculp · 2022-09-16T22:43:51Z

Fixed missing region from chained configuration.
Removed the extraneous else's.

Can you please also test cargo make check-repo-expirations, cargo make validate-repo, and cargo make refresh-repo?

The sdk allows not including Some if you set the values without set_. (This happens in a lot of places so might not be in the scope of this pr)

Suggested change

.set_device_name(Some(ROOT_DEVICE_NAME.to_string()))

.set_ebs(Some(

EbsBlockDevice::builder()

.set_delete_on_termination(Some(true))

.set_snapshot_id(Some(root_snapshot.clone()))

.set_volume_type(Some(VolumeType::from(VOLUME_TYPE)))

.set_volume_size(ami_args.root_volume_size)

.build(),

.device_name(ROOT_DEVICE_NAME.to_string())

.ebs(EbsBlockDevice::builder()

.delete_on_termination(true)

.snapshot_id(root_snapshot.clone())

.volume_type(VolumeType::from(VOLUME_TYPE))

.set_volume_size(ami_args.root_volume_size)

.build(),

This definitely works, but my understanding was the setters are more idiomatic for the SDK.

Where did you see the perspective on idiomatic use? Not disagreeing, and it's not a blocker here in any case, but for me the code that @ecpullen wrote seems preferable since it's fewer characters and we don't have to wrap everything in an Option.

It was just an impression we got from the SDK team that the non-setter way might eventually be deprecated.

jpculp · 2022-09-20T22:07:49Z

Brought back stronger-typed regions and region_from_string().
Renamed aws: AwsConfig to pubsys_aws_config: PubsysAwsConfig to reduce confusion.
Kept arch as a stronger-type throughout.
Replaced ImageState ensure statement with match.
Replaced thread::spawn with tokio::runtime::Runtime::new().

+fn region_from_string(name: &str) -> Result<Region> {
+    Ok(Region::new(name.to_owned()))


If this is infallible now we should probably just return a Region. However, I like it this way for the purposes of the SDK migration, to minimize the diff. Maybe add a FIXME to rework later.

This is a pretty quick change. Rather than a FIXME, should I just make it the final change once we think this PR hits all the edge cases?

jpculp · 2022-09-21T01:31:06Z

Changed credentials logic will run even if only a single role is specified.
Credential expirations can now be None.
Removed endpoints.

Rewrote client.rs to return providers instead of credentials.
Removed returning unneccessary result-types (and their associated error contexts).
