chore: migrate to aws-sdk-go-v2 (lightsail, route53)

[ldez]

The aws-sdk-for-go v2 is available since 2021/01/19

• old SDK
• new SDK
• migration guide

As the SDK has been split into a constellation of modules, this will potentially reduce the size of the dependencies.
(Edit: after a comparison this increase the size of the binary...)

It's a pure technical migration, I haven't tested the providers in a real context.

Fixes #1743

[dmke]

I don't think Github issues notifications when editing a comment, only when creating it. Let me try that again:

Pinging some people who have contributed in the past to these providers:

• @jvdbc (route53)
• @Mongey (route53)
• @aidansteele (route53)
• @paulgalow (route53)
• @dereknex (lightsail)
• @farmdawgnation (lightsail)
• @Clement-Jean (lightsail)
• @dicksonleong (lightsail)

Has anyone of you a bit free of time on their hands and still have access to Route53 or Lightsail and could check if all still work?

Not sure if it helps but a build with the new AWS SDK V2 worked for me

though i couldn't get the integration tests to pass, but that's probably more a config error

[dmke]

Thank you very much, @kingcdavid!

As for the integration test, I believe you need to call something like:

AWS_ACCESS_KEY_ID="..." \
AWS_SECRET_ACCESS_KEY="..." \
AWS_REGION="..." \
R53_DOMAIN="..." \
  go test -v -run TestLiveTTL github.com/go-acme/lego/v4/providers/dns/route53

where the AWS_* credentials are per usual, and R53_DOMAIN is the domain you have access to.

You can omit the -run TestLiveTTL to run all Route53 tests, not just the integration test.

[kingcdavid]

I tried that, but it still skipped the test, possibly need to add envDomain into the NewEnvTest?
If i do this, i can get the test to pass

diff --git a/providers/dns/route53/route53_test.go b/providers/dns/route53/route53_test.go
index 1c8e5f5f..c6028692 100644
--- a/providers/dns/route53/route53_test.go
+++ b/providers/dns/route53/route53_test.go
@@ -25,7 +25,8 @@ var envTest = tester.NewEnvTest(
        EnvMaxRetries,
        EnvTTL,

+       envDomain).
        WithDomain(envDomain).
        WithLiveTestRequirements(EnvAccessKeyID, EnvSecretAccessKey, EnvRegion, envDomain)

Then the tests pass

➜  lego git:(feat/migrate-aws-sdk-v2) ✗ go test -v -run TestLiveTTL github.com/go-acme/lego/v4/providers/dns/route53

--- PASS: TestLiveTTL (56.58s)
PASS
ok  	github.com/go-acme/lego/v4/providers/dns/route53	56.588s

also the route53.toml may need updating referencing the new SDK?

[ldez]

I updated the links.

enDomain should not be inside the constructor because it's handled by WithDomain, the problem is not here.

only EnvAccessKeyID, EnvSecretAccessKey, EnvRegion, envDomain are required to run the test.

Edit: I found and fix the problem.

[ldez]

Thank you a lot @kingcdavid ❤️

@dmke I think we can merge now: route53 was the more impacted by the migration and for lightsail it's mainly just modification of package names.

[dmke]

Ok, let's merge this :-)
