    Description

      The EC2 plugin is currently throwing the following error while trying to launch a build slave:

      The AWS API docs specify EC2 hostnames like the following:

      ...
      ec2.eu-central-1.amazonaws.com
      ...
      

      So, the "ec2" and "eu-central-1" portions are flipped. I recommend that the API endpoints are updated to use the hostnames that are currently outlined in the API docs.

          Because we have to start our Jenkins slaves in eu-central-1 I made the changes here.

          I also had to upgrade the AWS SDK because the requests to eu-central need a Signature Version 4 (see Problem accessing eu-central-1 with API)

          There seem to be some problems with newer versions of the AWS SDK so I'll have to investigate this before doing a pull request.

          Starting instances in eu-central-1 still does not work for me even though I use the latest version (1.29) of the Amazon EC2 plugin.

          Hi
          This is a problem for me as well, I don't know how the rest of the people are working with the current plugin.
          According to the code and this EC2 documentation the API endpoints that the plugin constructs will never work.

          This is just a simple URL constructing function that needs to be changed, there is even a pull request in github to get it fixed.

          Could we get that merged or the problem fixed please?

          No worries about the assignee. I have finally begun to look at this a bit and have commented on a previous pull request (https://github.com/jenkinsci/ec2-plugin/pull/161) that also claims to fix this (along with addressing the s3 hostnames [though it's unclear that that's required]). Hopefully we will get that other pull request in in the next day or so.

          I have made the fix. I can't make a release at the moment because there is another critical bug in the unreleased version that I have to fix. I will try and get to it soon.

          Can you verify this is working in the current (1.30) snapshot, and then I can release it?

          To be released in 1.30

          francisu Francis Upton added a comment - To be released in 1.30

          I tested a snapshot but ran into problems. First, the aws-java-sdk plugin is only available in version 1.10.26 from within Jenkins but the EC2 plugin depends on 1.10.16.
          You should probably update to 1.10.26 prior to release.
          I got the 1.10.16 version of aws-java-sdk from the archive and could manually install the 1.30-SNAPSHOT of the ec2 plugin.

          When I tried to test the connection from withing "Manage Jenkins" -> "Cloud" -> "Amazon EC2" for the AZ eu-central-1 i got an error:

          AWS was not able to validate the provided access credentials (Service: AmazonEC2; Status Code: 401; Error Code: AuthFailure; Request ID: ea2e20e5-1e5f-4339-be55-721b6b1a66bc)

          When I try to test the connection to any other availability zone where the the key is missing I get

          The EC2 key pair private key isn't registered to this EC2 region (fingerprint is fd:1c:<redacted>:7e)

          It seems like there is still a problem with the APIs and eu-central-1

          It could be that I did something strange but I think the error I got is worth looking into.

          @allotria: I had the same problem with aws-java-sdk and with the 401 error. But I discovered that in my case it was not the fault of the ec2-plugin: While the IAM credentials worked with aws-cli from my laptop, I got the same 401 error when using the aws-cli from the EC2 instance where Jenkins was running.

          Can you confirm if you experience the same behavior?

          Hi,

          I just included this pull request (https://github.com/jenkinsci/ec2-plugin/pull/172) and rebuilded the ec2 pluging localy.
          Now the plugin works fine with eu-central-1.

          Br,
          Jörg

          francisu, any update on the release schedule for 1.30? And will this issue be fixed in 1.30?

          It would be really great to see a new release of this plugin. My team has seen a few issues working with the ec2-plugin, and we're hoping things will get smoother soon. On GitHub, there have been 14 commits to the master branch since the last release (August 2, 2015). One notable change (IMHO), is that the aws-java-sdk dependency has been upgraded from version 1.10.2 (used in the last release) to 1.10.26 (currently in the master branch).

          Can someone please comment as to when an update is expected, or if another plugin should be preferred?

          Unfortunately there are some regressions in the current master unreleased version. I'm going to try and address those in the next few days and once they are fixed and it seems reliable, I will do a new release.

          I'd like to second bbl5660 here and hope that the regressions are smoothed out soon. The new release would save us a great deal of testing time if we can boots the slaves in the same data center as our master.

          I have finished my work on 1.30 snapshot, I would like some additional testing before I make the release, which I can do any day now.
