Stefan Müller updated LIBCLOUD-528:
-----------------------------------
Description:
Using NodeAuthSSHKey with EC2 fails:
{code}
auth = NodeAuthSSHKey("ssh-rsa .... [email protected]")
driver.create_node(...., auth=auth)
{code}
This produces an error message:
{code}
SignatureDoesNotMatch: The request signature we calculated does not match the
signature you provided. Check your AWS Secret Access Key and signing method.
Consult the service documentation for details
{code}
The same code with the {{auth=auth}} argument removed works.
I've investigated a bit and found a possible cause in
{{compute/drivers/ec2.py}} (around line 1358):
{code}
if 'auth' in kwargs:
auth = self._get_and_check_auth(kwargs['auth'])
params['KeyName'] = \
self.ex_find_or_import_keypair_by_key_material(auth.pubkey)
{code}
The {{ex_find_or_import_keypair_by_key_material}} returns a {{dict}}, yet
{{params['KeyName']}} should be a string.
If I change it to
{code}
if 'auth' in kwargs:
auth = self._get_and_check_auth(kwargs['auth'])
params['KeyName'] = \
self.ex_find_or_import_keypair_by_key_material(auth.pubkey)['keyName']
{code}
Then it works fine.
