Updating Stemcells for External Workers
This topic describes how to update stemcells for External Workers. These stemcells need to be updated to ensure compatibility with your version of Concourse.
To update stemcells, do the following:
/cluster/external-worker.ymland look for the
versionproperty in the
yaml # before ... stemcells: ... version: OLD-STEMCELL-VERSION ...
Update the version to the recommended stemcell version for your version of Concourse.
yaml # after ... stemcells: ... version: 621.74 ...
For Concourse v6.3.0, Pivotal recommends that you use a 621.x stemcell.
Run your deploy script to trigger the update.
