Difficulties with Route 53 #47

Closed sapid closed 8 months ago

sapid commented 8 months ago

My current goal is to create a wildcard SSL cert on a network behind a NAT. As such, I'm trying to use the DNS-01 challenge method using an API for Route 53. I'm using a root-less installation, and I have legocerthub running on linux (not in Docker) using the provided installation script (scripts/install.sh) with the caveat that I did not grant CAP_NET_BIND_SERVICE to legocerthub since I don't plan on exposing a port through the NAT for the http challenge (in spite of the headache it would save me).

I've successfully used both lego and acme.sh to accomplish cert issuance with the Let's Encrypt staging ACME server with my credentials for Route 53, but I get errors in legocerthub when I use either Providers dns01acmesh or dns01goacme. All of these experiments below are performed from the same machine.

dns01acmesh

In the case of dns01acmesh, it looks to me like the root cause is that something is preventing acme.sh from reading from or writing to its config file. I get this error when acme.sh's path is specific as /opt/legocerthub/.acme.sh and as /opt/legocerthub/scripts/acme.sh. (The write error could be a red herring if not saving the config is the intended outcome, but as I mentioned above, the same tokens specified here work from the cli with both tools, and they look correct in data/app/config.yaml, so the alternative appears perhaps to be passing the credentials to acme.sh incorrectly.)

The valid CLI invocation looks like:

./acme.sh --install --accountemail my@valid.email
./acme.sh --set-default-ca --server letsencrypt_test
export AWS_ACCESS_KEY_ID="MY_VALID_KEY"
export AWS_SECRET_ACCESS_KEY="MY_VALID_SECRET_KEY"
export AWS_HOSTED_ZONE_ID="MY_ZONE_ID"
./acme.sh --issue --dns dns_aws --keylength 4096 -d *.int.my_valid_domain.com

Config for dns01acmesh:

Relevant log output

After successfully fetching the challenge, here's what the logs look like. I wish the debug log level showed how acme.sh is being invoked.

Relevant log output

This one's a bit more puzzling to me, though my (perhaps naive) guess is that it's trying to query EC2 IMDS at 169.254.169.254 instead of directly using the provided credentials with route53.amazonaws.com. (Trying to verify the credentials with IMDS this way will fail in my idiosyncratic case - the IMDS for my Route 53 AWS account and my network AWS account are disjoint.)

Explicitly declared credentials for dns01goacme

Modifying the configuration slightly renders a slightly different error message, but I think it supports my IMDS theory. If, instead of referencing the credential file, I specify AWS_ACCESS_KEY_ID="MY_VALID_KEY" and AWS_SECRET_ACCESS_KEY="MY_VALID_SECRET_KEY", I get the following log output instead. The error suggests I don't have valid credentials, but invoking aws route53 list-resource-record-sets --hosted-zone-id from the terminal verifies that I do have that IAM permission for these credentials.

If you are using quotes around the values of your variables, remove them.

I need to add to my to-do list to deal with if people do that since it’s a pretty common format.

If that’s not it, let me know.

sapid commented 8 months ago

:facepalm: Yep, that was it. I didn't look closely enough at config.example.yaml to notice that environment variables don't share the same format as all other arguments.

I'll also make some new screenshots for dns01 acme.sh and dns01 go-acme le-go and make a PR.

sapid commented 8 months ago

I submitted https://github.com/gregtwallace/legocerthub.com-docusaurus/pull/2 for this issue.

gregtwallace commented 7 months ago

The new version is building and the this should work now with or without quotes. Thanks for raising this. The update should avoid what might be a common confusion since the param format often includes quotes.
