tiup mirror genkey

tiup mirror genkey

TiUP mirror, according its definition, has three roles of users:

  • Mirror administrators: They have the permission to modify root.json, index.json, snapshot.json, and timestamp.json.
  • Component owners: They have the permission to modify the corresponding component.
  • Normal users: They can download and use the components.

Because TiUP requires the signature of the corresponding owner/administrator to modify a file, owners/administrators must have his or her own private key. The command tiup mirror genkey is used to generate a private key.

Warning:

DO NOT transmit private keys over the Internet.
