tiup mirror merge

The tiup mirror merge command is used to merge one or more mirrors to the current mirror.

To execute this command, the following conditions must be met:

  • The owner IDs of all components of the target mirror exist in the current mirror.
  • The ${TIUP_HOME}/keys directory of the user who executes this command contains all the private keys corresponding to the above owner IDs in the current mirror (you can use the command tiup mirror set to switch the current mirror to the mirror that is currently authorized to modify).


tiup mirror merge <mirror-dir-1> [mirror-dir-N] [flags]
  • <mirror-dir-1>: the first mirror to be merged into the current mirror
  • [mirror-dir-N]: the Nth mirror to be merged into the current mirror




  • If the command is executed successfully, there is no output.
  • If the current mirror does not have a component owner of the target mirror, or if ${TIUP_HOME}/keys does not have the owner's private key, TiUP reports the Error: missing owner keys for owner %s on component %s error.
