git credential helper using AWS SSM parameter store.
AWS auth is fetched from EC2 IMDS by default. However you can specify -default-credential-chain to use AWS default credential chain.
The credential helper currently only supports the get operation.
If the git-credential-ssm binary is in $PATH or $GIT_EXEC_PATH, it can be referenced as below:
git config credential.helper "ssm -parameter <name or arn>"
Otherwise
git config credential.helper "/path/to/git-credential-ssm -parameter <name or arn>"
Run using default AWS credential chain:
go build
./git-credential-ssm -parameter /my/parameter -default-credential-chain
Run using EC2 IMDS:
aws-vault exec <role-name> --ec2-server
./git-credential-ssm -parameter /my/parameter
