Artifact Manager on S3 plugin

Artifact Manager on S3 plugin is an Artifact Manager that allow you to store you artifacts into a S3 Bucket on Amazon. The use of this S3 Bucket as a artifact storage is transparent to Jenkins and your jobs, it works like the default Artifact Manager.

Artifact manager implementation for Amazon S3, currently using the jClouds library. wiki

Prerequisites

First of all, you will need a Amazon account, this Amazon account should have permissions over the S3 Bucket that you want to use as artifact storage.

The plugin is expected to run with a IAM profile and the S3 bucket must be already created. When running in AWS that means the instance needs to have an IAM role set with a policy that allows access to the S3 bucket to be used.

This is an example policy

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "AllowListingOfFolder",
            "Effect": "Allow",
            "Action": "s3:ListBucket",
            "Resource": "arn:aws:s3:::my-bucket-name",
            "Condition": {
                "StringLike": {
                    "s3:prefix": "some/path/*"
                }
            }
        },
        {
            "Sid": "AllowS3ActionsInFolder",
            "Effect": "Allow",
            "Action": [
                "s3:PutObject",
                "s3:GetObject",
                "s3:DeleteObject",
                "s3:ListObjects"
            ],
            "Resource": "arn:aws:s3:::my-bucket-name/some/path/*"
        }
    ]
}

Configuration

In order to configure the plugin on Jenkins, you have to go to Manage Jenkins/Configure System to the Artifact Managment for Builds section, there you have to select the Cloud Provider Amazon S3.

Then you have to configure your credentials to access the AWS services, go to Manage Jenkins/Amazon Web Services Configuration, there you can configure the Region and the Amazon Credentials to use, you have to save or apply this setting before to continue. For more details check AWS Credentials

S3 Bucket Region: Region to use to generate the URLs to get/put artifacts, by default it is autodetected.

After that you can configure the S3 Bucket settings on Manage Jenkins/Amazon Web Services Configuration on the section Amazon S3 Bucket Access settings in the same configuration page.

S3 Bucket Name: Name of the S3 Bucket to use to store artifacts.
Base Prefix: Prefix to use for files and folders inside the S3 Bucket, if the prefix is a folder should be end with /.

Every field on the configuration form has a validation, this validation will check that the field value is a proper value.

If you save a wrong configuration, you will see a related error explained why, then you have to came back to the configuration page to set the proper value.

Before saving the configuration, we recommend you to test the configuration by using the "Validate S3 Bucket configuration" button. This button will test the bucket exists and the credentials used are valid and has access to the bucket. See the troubleshooting section for more details about the reported error.

Finally the "Create S3 Bucket from configuration" button allow you to create the bucket if it does not exist and the AWS credentials configured have permission to create a S3 Bucket.

How to use Artifact Manager on S3 plugin

Artifact Manager on S3 plugin is transparently used by the Jenkins Artifact system, so as other Artifacts Managers, you only have to use the Artifact Step to archive/unarchive, and the stash/unstash step, let's see how it works. We have also to mention here, the Copy Artifacts plugin that allow you to download artifacts from a finished build.

Pipeline job

Artifact Manager on S3 plugin can be use in a Pipeline job, you have to use the archiveArtifacts step to archive artifacts in the S3 Bucket, for more details you can check the archiveArtifacts step documentation

node() {
    //you build stuff
    //...
    stage('Archive') {
        archiveArtifacts "my-artifacts-pattern/*"
    }
}

for unarchive artifacts you have to use the unarchive step that will retrieve the artifacts from S3 Bucket, the mapping parameter is list of pairs source-filename destination-filename, for more details you can check the unarchive step documentation

node() {
    //you build stuff
    //...
    stage('Unarchive') {
        unarchive mapping: ["my-artifacts-pattern/": '.']
    }
}

to save a set of files for use later in the same build, generally on another node/workspace, you can use stash, stash step will store those files on the S3 Bucket for later use.

node() {
    //you build stuff
    //...
    stash name: 'stuff', includes: '*'
}

to retrieve those files saved with the stash step you have to use the unstash step, unstash will retrieve the files from the S3 Bucket to the local workspace.

node() {
    //you build stuff
    //...
    unstash 'stuff'
}

FreeStyle job

On FreeStyle jobs, you can archive artifacts by using a Post-build Action of type Archive the Artifacts, this step would use the Artifact Manager on S3 plugin to store the artifacts into the S3 Bucket.

Manage Artifacts

The default behaviour of the plugin it is not delete artifact from the S3 Bucket, so the artifacts storaged on the S3 Bucket would be in the S3 bucket even do you remove the build from Jenkins. If you want to change this behaviour you should define a couple of JVM properties.

Delete Artifacts

In order to delete artifacts on the S3 Bucket, you would have to add the property -Dio.jenkins.plugins.artifact_manager_jclouds.s3.S3BlobStoreConfig.deleteArtifacts=true to your Jenkins JVM properties , if it is not set the artifacts will not be deleted from S3 Bucket when the corresponding build is deleted.

Delete Stash

In order to delete artifacts on the S3 Bucket, you would have to add the property -Dio.jenkins.plugins.artifact_manager_jclouds.s3.S3BlobStoreConfig.deleteStashes=true to your Jenkins JVM properties , if it is not set the stash will not be deleted from S3 when the corresponding build is deleted.

AWS Credentials

Artifact Manager on S3 plugin needs an AWS credentials in order to access to the S3 Bucket, you can select one on the configuration page. If you do not select any AWS credential and keep the "" dropdown on the option "IAM instance Profile/user AWS configuration" Artifact Manager on S3 plugin would try to use the IAM instance profile credentials of the Jenkins host, or user AWS configuration (~/.aws).

Every time you archive/unarchive or download an artifact, Jenkins will generate a temporary URL, it will be valid for an hour, so if you try to reuse an artifact download URL one hour later was generated, it will not be valid, you cannot download the artifact with that URL any more, thus you have to go back to Jenkins and click on the artifact to download it again.

If you use a regular Key/Secret AWS Credentials you can set the token duration by adding the property -Dio.jenkins.plugins.artifact_manager_jclouds.s3.S3BlobStoreConfig.sessionDuration to the Jenkins JVM properties, the default value is one hour. However if you set and IAM Role to assume on the AWS credential, the token duration is always one hour, this parameter does not change the duration in AWS Credentials Plugin settings.

Extending Artifact Manager on S3 plugin

Testing

Pick an AWS profile and region, then create a scratch bucket and choose a subdirectory within it for testing. Add to your ~/.m2/settings.xml:

    <profiles>
        <profile>
            <id>artifact-manager-s3</id>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
            <properties>
                <AWS_PROFILE>…</AWS_PROFILE>
                <AWS_REGION>…</AWS_REGION>
                <S3_BUCKET>…</S3_BUCKET>
                <S3_DIR>…/</S3_DIR>
            </properties>
        </profile>
    </profiles>

Now log in to AWS so that ~/.aws/credentials is up to date with valid credentials, and run:

mvn clean test

For interactive testing, you may instead add to ~/.mavenrc (cf. comment in MNG-6303):

export AWS_PROFILE=…
export AWS_REGION=…

then:

mvn hpi:run

An example pipeline for testing:

timestamps {
  node('uploader') {
    writeFile file: 'f', text: 'some content here'
    archiveArtifacts 'f'
  }
  node('downloader') {
    sh 'ls -l'
    unarchive mapping: [f: 'f']
    sh 'ls -l; cat f'
  }
}

You can also install the log-cli plugin, and run:

java -jar jenkins-cli.jar -s http://localhost:8080/jenkins/ tail-log io.jenkins.plugins.artifact_manager_jclouds -l ALL

Or to just see HTTP traffic:

java -jar jenkins-cli.jar -s http://localhost:8080/jenkins/ tail-log org.jclouds.rest.internal.InvokeHttpMethod -l FINE

Troubleshooting

No valid session credentials

The AWS credentials has to have the token attribute, Basic AWS credentials are not valid. You would see the following errors in the Jenkins Logs
