<h2>eucarc <small>EC2 settings</small></h2>
<p><code>eucarc</code> creates EC2 credentials for the current user as
defined by <code>OS_TENANT_NAME:OS_USERNAME</code>.
<code>eucarc</code> sources <code>openrc</code> at the beginning
(which in turn sources <code>stackrc</code> and <code>localrc</code>)
in order to set credentials to create EC2 credentials in Keystone.
</div>
<dl>
<dt>EC2_URL</dt>
<dd>Set the EC2 url for euca2ools. The endpoint is extracted from the
service catalog for <code>OS_TENANT_NAME:OS_USERNAME</code>.
<pre>EC2_URL=$(keystone catalog --service ec2 | awk '/ publicURL / { print $4 }')</pre></dd>
<dt>S3_URL</dt>
<dd>Set the S3 endpoint for euca2ools. The endpoint is extracted from the
service catalog for <code>OS_TENANT_NAME:OS_USERNAME</code>.
<pre>export S3_URL=$(keystone catalog --service s3 | awk '/ publicURL / { print $4 }')</pre></dd>
<dt>EC2_ACCESS_KEY, EC2_SECRET_KEY</dt>
<dd>Create EC2 credentials for the current tenant:user in Keystone.
<pre>CREDS=$(keystone ec2-credentials-create)
export EC2_ACCESS_KEY=$(echo "$CREDS" | awk '/ access / { print $4 }')
export EC2_SECRET_KEY=$(echo "$CREDS" | awk '/ secret / { print $4 }')</pre></dd>
<dt>Certificates for Bundling</dt>
<dd>Euca2ools requires certificate files to enable bundle uploading.
The exercise script <code>exercises/bundle.sh</code> demonstrated
retrieving certificates using the Nova CLI.
<pre>EC2_PRIVATE_KEY=pk.pem
EC2_CERT=cert.pem
NOVA_CERT=cacert.pem
EUCALYPTUS_CERT=${NOVA_CERT}</pre></dd>
