amazon beanstalk ec2 instance当前git sha

Question

How can I get current git sha of the commit that was git aws.push ? My container_commands need to download a file on a server that has that head git sha as the file name so I need a way to determine it.

I've been browsing around /opt/elasticbanstalk/ and found file /opt/elasticbeanstalk/deploy/configuration/appsourceurl which contains

"url": "https://elasticbeanstalk-us-west-43434324.s3.amazonaws.com/resources%2Fenvironments%2Dg-fea2ffeaf5%2F_runtime%2F_versions%2Fbb-test-eb%2Fgit-6cb3416a7a5a84ce864dd0213236984age4b0b9-2678564154681?Expires=1417813357&AWSAccessKeyId=-----&Signature=-----"

I could parse this and extract the git-sha the problem this git sha is different from my git head sha on local that I just git aws.pushed! Why?

You can confirm version label (aka git commit) with AWS Elastic Beanstalk API Command Line Interface :

$ elastic-beanstalk-describe-applications
ApplicationName | ConfigurationTemplates | DateCreated | DateUpdated | Description | Versions
---------------------------------------------------------------------------------------------

It should match your local commit:

$ git rev-parse HEAD
c069d943a152871a3a43898ce19ea20295b1307d

Also, look for archive operation in the log:

2013-12-08 03:51:31,830 [INFO] (10377 MainThread) [directoryHooksExecutor.py-29] [root directoryHooksExecutor info] Output from script: Archive:  /opt/elasticbeanstalk/deploy/appsource/source_bundle
