[question] version of etcd #47

Closed eujungkim closed 7 years ago

eujungkim commented 7 years ago

The newest etcd version is 3.2 now but etcd-releases uses etcd version 2.2.0. Is there any reason for using version 2.x, or a plan to upgrade etcd version?

We have created an issue in Pivotal Tracker to manage this:

The labels on this github issue will be updated when the story is started.

I've got answer like below in slack. So I close this issue.

we don't have a plan to upgrade etcd, but we plan to remove our final usage of etcd in cf-release (it is done, just not the default yet as far as I know). Upgrading from 2 to 3 requires extracting all data from the version 2 database and inserting it into the version 3 database, so we did not make plans to orchestrate that migration, but instead invested in moving doppler/metron coordination off of etcd. If etcd released a CVE we might consider performing this migration and moving to latest, but otherwise it would be a large effort that would benefit CF for only a short time
