Configuring Signers

To use hanko, a set of signers to track need to be configured first. As an example, we'll create a configuration file in the default location ~/.config/hanko/config.toml containing a single signer using the default GitHub source.

[[signers]]
name = "octocat"
principals = ["octocat@github.com"]

Updating the allowed signers file

Once we've configured our signers, we can run the update command.

If an allowed signers file is configured in Git, hanko will write to that file. Should no allowed signers file be configured within Git, or you want to specify a different path, the --file runtime option may be used.

$ hanko -v update
