org.springframework.cloud.config.server.support.AwsCodeCommitCredentialProvider

public class AwsCodeCommitCredentialProvider
extends org.eclipse.jgit.transport.CredentialsProvider

Provides a jgit CredentialsProvider implementation that can provide the appropriate credentials to connect to an AWS CodeCommit repository.

From the command line, you can configure git to use AWS code commit with a credential helper. However, jgit does not support credential helper commands, but it does provide a CredentialsProvider abstract class we can extend. Connecting to an AWS CodeCommit (codecommit) repository requires an AWS access key and secret key. These are used to calculate a signature for the git request. The AWS access key is used as the codecommit username, and the calculated signature is used as the password. The process for calculating this signature is documented very well at https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html.

Method Detail

calculateCodeCommitPassword

protected static String calculateCodeCommitPassword(org.eclipse.jgit.transport.URIish uri,
                                                    String awsSecretKey)

Calculate the AWS CodeCommit password for the provided URI and AWS secret key. This uses the algorithm published by AWS at https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html

Parameters:

uri - the codecommit repository uri

awsSecretKey - the aws secret key

Returns:

the password to use in the git request

canHandle

public static boolean canHandle(String uri)

This provider can handle uris like https://git-codecommit.$AWS_REGION.amazonaws.com/v1/repos/$REPO .

Parameters:

uri - uri to parse

Returns:

true if the URI can be handled

isInteractive

public boolean isInteractive()

This credentials provider cannot run interactively.

Specified by:

isInteractive in class org.eclipse.jgit.transport.CredentialsProvider

Returns:

false

See Also:

CredentialsProvider.isInteractive()

supports

public boolean supports(org.eclipse.jgit.transport.CredentialItem... items)

We support username and password credential items only.

Specified by:

supports in class org.eclipse.jgit.transport.CredentialsProvider

CredentialsProvider.supports(org.eclipse.jgit.transport.CredentialItem[])

get

public boolean get(org.eclipse.jgit.transport.URIish uri,
                   org.eclipse.jgit.transport.CredentialItem... items)
            throws org.eclipse.jgit.errors.UnsupportedCredentialItem

Get the username and password to use for the given uri.

Specified by:

get in class org.eclipse.jgit.transport.CredentialsProvider

Throws:

org.eclipse.jgit.errors.UnsupportedCredentialItem

See Also:

CredentialsProvider.get(org.eclipse.jgit.transport.URIish, org.eclipse.jgit.transport.CredentialItem[])

reset

public void reset(org.eclipse.jgit.transport.URIish uri)

Throw out cached data and force retrieval of AWS credentials.

Overrides:

reset in class org.eclipse.jgit.transport.CredentialsProvider

Parameters:

uri - This parameter is not used in this implementation.

getAwsCredentialProvider

public com.amazonaws.auth.AWSCredentialsProvider getAwsCredentialProvider()
