Thank you for pointing this out. I've tried
$ euca-describe-instances
EC2_ACCESS_KEY environment variable must be set.
Connection failed
while having EC2_CERT and EC2_PRIVATE_KEY setup and in shell where
ec2-describe-instances works. The man euca-describe-instances(1) says
that
Euca2ools will use the environment variables EC2_URL, EC2_ACCESS_KEY,
EC2_SECRET_KEY, EC2_CERT, EC2_PRIVATE_KEY, S3_URL, EUCALYPTUS_CERT by
default.
Is there anything else I need to have setup beyond EC2_CERT and
EC2_PRIVATE_KEY?
Euca2ools programs don't hard-code things like URIs, so you typically
need to specify more in the environment to get them to work with AWS.
I recommend setting everything of importance up in your shell's rc file.
For instance, my .zshrc file contains something similar to this:
export S3_URL=https://s3.amazonaws.com:443
export EC2_URL=https://ec2.amazonaws.com:443
export EC2_PRIVATE_KEY=~/ec2/euca2-gholms-00000000-pk.pem
export EC2_CERT=~/ec2/euca2-gholms-00000000-cert.pem
export EC2_ACCESS_KEY='00000000000000000000'
export EC2_SECRET_KEY='0000000000000000000000000000000000000000'
...where the '0's are replaced with account-specific numbers and things.
At the moment you need all six of these variables, though the *_KEY
variables may not be necessary in future releases.
