We want to be able to retrieve the elastic beanstalk application version in our PHP code. I don't see that EB passes it to us in any server configuration files, which I find it strange. Does anyone else know how we might be able to get this?

  • AFAIK, when Elastic Beanstalk deploys your application to the cloud, it creates an archive with `git archive` command. The resulting archive file does not have any repository metadata. – kukido Dec 26 '13 at 06:14

At least for Docker containers - you can use the information stored in /opt/elasticbeanstalk/deploy/manifest.

I've just been looking for a solution myself.

For now, at least, the following works:

unzip -z "${EB_CONFIG_SOURCE_BUNDLE}" | tail -n1

To elaborate,$EB_CONFIG_SOURCE_BUNDLE contains a path to the zip archive of your application (i.e. /opt/elasticbeanstalk/deploy/appsource/source_bundle). The version tag is embedded as a comment in this file.

    In case anyone stumbles across this, this apparently does not work for Ruby containers. – mentat Jan 17 '14 at 01:30
  • @mentat - does the envvar not exist or is the file missing, or both? It's expected that each lang environment has it's own deployment implementation but I would have thought the process of getting the code onto the server would be consistent.If you find a solution please could you follow up, or contribute to https://github.com/apancutt/aws-eb-newrelic-deploynotify – apancutt Jan 17 '14 at 08:07
  • The envvar exists but it looks like the output is perhaps a hash. I'll take a closer look at the actual file to see where it's embedded. Are you using the aws git to push or something else? – mentat Jan 17 '14 at 20:11

    Yes, using git to deploy (aws.push). The hash is the latest git commit which Elastic Beanstalk uses as the version label - at least for PHP applications. – apancutt Jan 18 '14 at 10:00
  • I saw no such environment variable for a node container, so just used hardcoded `/opt/elasticbeanstalk/deploy/appsource/source_bundle` (yuck) – Carl Jun 03 '15 at 21:02

    `unzip -z "/opt/elasticbeanstalk/deploy/appsource/source_bundle" | awk 'NR==2 { printf("%.7s\n", $1) }'` is the equivalant to `git rev-parse --short HEAD` – John Morales Dec 18 '15 at 18:52

Consolidating on the answers from @Georgij and @IanBlenke here are the ways you can find the version.

1. Most Reliable (Manifest)

You can sudo cat /opt/elasticbeanstalk/deploy/manifest

Output:

{"RuntimeSources":{"PLATFORM_NAME":{"app-ae22-190115_152512":{"s3url":""}}},"DeploymentId":45,"Serial":53}

2. You can look at the eb-activity logs

Secondly you could look at the eb-activity logs. This will only show you in the log line... You have to assume it's been a successful installation too..

tail /var/log/eb-activity.log | grep -i "app-.*@"

You can use AWS Elastic Beanstalk API to retrieve your application version information.

Describe Application Versions returns descriptions for existing application versions.

Sample request

https://elasticbeanstalk.us-east-1.amazon.com/?ApplicationName=SampleApp
&Operation=DescribeApplicationVersions
&AuthParams

Sample response

<DescribeApplicationVersionsResponse xmlns="https://elasticbeanstalk.amazonaws.com/docs/2010-12-01/">
  <DescribeApplicationVersionsResult>
    <ApplicationVersions>
      <member>
        <SourceBundle>
          <S3Bucket>amazonaws.com</S3Bucket>
          <S3Key>sample.war</S3Key>
        </SourceBundle>
        <VersionLabel>Version1</VersionLabel>
        <Description>description</Description>
        <ApplicationName>SampleApp</ApplicationName>
        <DateCreated>2010-11-17T03:21:59.161Z</DateCreated>
        <DateUpdated>2010-11-17T03:21:59.161Z</DateUpdated>
      </member>
    </ApplicationVersions>
  </DescribeApplicationVersionsResult>
  <ResponseMetadata>
    <RequestId>773cd80a-f26c-11df-8a78-9f77047e0d0c</RequestId>
  </ResponseMetadata>
</DescribeApplicationVersionsResponse>

While the best way is really to ask AWS directly:

aws elasticbeanstalk describe-environments  | \
    jq -r '.Environments | .[] | .EnvironmentName + " " + .VersionLabel'

I've had limited success deducing the same 4 or 5 digit hash by using:

git rev-parse --short=4 $(git log -1 --pretty=format:%h)

tail /var/log/eb-activity.log | grep -i "\[Application update .*\] : Completed activity." | tail -1 | sed -E 's/.*Application update (.*)@.*/\1/'

Outputs the actual app version ID like app-2.15.0-31-gf4a2918 in our case.

This works from inside any EB EC2, requires no API hit or git repo (some deploy by zip). Useful for sending a notification about a recent deployment.

In PHP application, you can get it using

aws elasticbeanstalk describe-environments --environment-names <environment-name>

You should add the below environment variables in the php script to get it working.

AWS_DEFAULT_REGION AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY

I have used putenv() function to set the environment variables and shell_exec() to get the json output. Parsed the json output to get the VersionLabel which is the actual application version.

On the Python platform, the version details can be found in the EC2 instance:

sudo cat /opt/elasticbeanstalk/deployment/app_version_manifest.json
