POaws ec2 request-spot-instances CLI issues
text
Body
copied!<p>Trying to start a couple of spot instances within a simple script, and the syntax supplied in the AWS documentation and aws ec2 request-spot-instances help output is listed in either JAVA or JSON syntax. How does one enter the parameters under the JSON syntax from inside a shell script?</p> <p>aws --version</p> <p>aws-cli/1.2.6 Python/2.6.5 Linux/2.6.21.7-2.fc8xen</p> <p>aws ec2 request-spot-instances help -- at the start of "launch specification" it lists JSON syntax</p> <p>--launch-specification (structure) Specifies additional launch instance information.</p> <pre><code> JSON Syntax: { "ImageId": "string", "KeyName": "string", }, .... "EbsOptimized": true|false, "SecurityGroupIds": ["string", ...], "SecurityGroups": ["string", ...] } </code></pre> <p>I have tried every possible combination of the following, adding & moving brackets, quotes, changing options, etc, all to no avail. What would be the correct formatting of the variable $launch below to have this work? Other command variations -- "ec2-request-spot-instances" are not working in my environment, nor does it work if I try to substitute --spot-price with -p.</p> <pre><code>#!/bin/bash launch="{"ImageId":"ami-a999999","InstanceType":"c1.medium"} "SecurityGroups":"launch-wizard-6"" echo $launch aws ec2 request-spot-instances --spot-price 0.01 --instance-count 1 --type c1.small --launch-specification $launch </code></pre> <p>This provides result: Unknown options: SecurityGroups:launch-wizard-6</p> <p>Substituting the security group number has the same result.</p> <p>aws ec2 describe-instances works perfectly, as does aws ec2 start-instance, so the environment and account information are properly setup, but I need to utilize spot pricing.</p> <p>In fact, nothing is working as listed in this user documentation: <a href="http://docs.aws.amazon.com/AWSEC2/latest/CommandLineReference/ApiReference-cmd-RequestSpotInstances.html" rel="nofollow">http://docs.aws.amazon.com/AWSEC2/latest/CommandLineReference/ApiReference-cmd-RequestSpotInstances.html</a></p> <p>Thank you,</p>
