You can update the Mirror field value by using the following REST endpoint:

POST /rest/stash/latest/bulk/APPLICATION_LINK_ID/mirror  

• APPLICATION_LINK_ID: the ID of a linked Bitbucket Data Center and Server instance. Read below for more info on how to find it.

Payload format

1. Perform a dry run (without an actual update), and reset all repositories to the master node. This will allow you to disable the usage of mirrors for all Bitbucket Data Center and Server repositories in Bamboo.

   {
   	resetToPrimary:true,
   	dryRun:true
   }

   Here's a sample output:

   ]

2. Update all Bitbucket Data Center and Server repositories, so they start using the provided mirror.

   {
   	mirrorId:"MIRROR_ID",
   	ignoreErrors: true
   }

   This will tell all repositories linked to a given Bitbucket Data Center and Server Application Link to use the provided mirror. The ignoreErrors flag allows to skip updating repositories that aren't supported by the given mirror. The response will contain all affected repositories.

Obtaining the Bitbucket Server Application Link value

Use the following snippet to print the list of all Bitbucket Data Center and Server instances known to Bamboo, together with their Application Link IDs:

curl -H "Content-Type: application/json" -H "Accept: application/json" http://BAMBOO_URL/rest/stash/latest/servers

Obtaining the Mirror ID value:

Use the following snippet to print the mirror servers that are configured in Bitbucket Data Center and Server, together with their IDs:

curl -H "Accept: application/json" https://BITBUCKET_SERVER_URL/rest/mirroring/latest/mirrorServers
