Specifying EC2 keypair?

[David Bosschaert <da...@gmail.com>]

Hi all,

I'm creating nodes on EC2 with ComputeService.createNodesInGroup() and
would like to use a keypair provided by Amazon as a .pem file to
access it later.

I thought that I could do this by passing the content of the .pem file
into the EC2TemplateOptions like this:
 EC2TemplateOptions opts = EC2TemplateOptions.Builder
   .keyPair(keyPairString)

However, that gives me the following error message:
  "please use options.overrideLoginCredentialWith(rsa_private_text)
    at com.google.common.base.Preconditions.checkArgument(Preconditions.java:120)"

However that overrideLoginCredentialWith() method doesn't exist on the
EC2TemplateOptions.

Is there a way to use the key that I received as .pem file for nodes
that I create with ComputeService.createNodesInGroup()?

Thanks,

David

Thanks for the details, David - glad to hear it's working!

Hi!

I'm a bit late, but you should be able to just do:

TemplateOptions options = compute.templateOptions()
   .authorizePublicKey("pubkey string")
   .inboundPorts(inboundPorts)
   .runScript(bootInstructions);

Without using EC2 specific options (more portable code) or all those
credential overrides. That should be enough, as the "authorizePublicKey"
should take care of creating a key pair for you.

Thanks Andrew,

After some more experimenting I found out how it works. The
EC2TemplateOptions.keyPair() method takes the name of the key under
which you registered it with AWS. So it could be something as simple
as "davids_key" or something. I mistakenly thought that you had to
pass the actual public key content through that method.

To create instances that I can then later log into using my key, I'm
currently doing the following:
  AdminAccess bootInstructions =
AdminAccess.builder().adminUsername("ec2-user").
    adminPublicKey(myPublicKeyContent).build();

  EC2TemplateOptions opts = EC2TemplateOptions.Builder
    .overrideLoginCredentials(

LoginCredentials.builder().user("ec2-user").privateKey(myPrivateKeyContent).build())
    .keyPair("davids_key") // the name I gave my key when I uploaded it to
AWS
    .inboundPorts(inboundPorts)
    .runScript(bootInstructions);

  TemplateBuilder templateBuilder = compute.templateBuilder();
  templateBuilder
    .hardwareId(instanceType)
    .imageId(imageID)
    .options(opts);
  compute.createNodesInGroup("myGroupName", 1, templateBuilder.build());

This is working fine for me. I can also log into the instances created using
  ssh -i <myprivatekey> ec2-user@1.2.3.4
If someone spots anything wrong with it, let me know :)

Cheers,

David

BTW I'm currently using JCouds 1.7.3

Which version of jclouds are you using, David? According to the  
Javadocs [1], EC2TemplateOptions should have a number of  
"overrideLogin*" methods.

But you're right, there seems to be a typo there: I suspect the  
intended method is either "overrideLoginCredentials" or  
"overrideLoginPrivateKey".

Hope that helps!
