Recently as part of OS update, docker was updated to 19.03.1.
Here is my environment:
OS: RHEL 7.7
Rancher (in HA): 2.2.6 - stable
Client: Docker Engine - Community
API version: 1.40
While trying to take a one-time snapshot (one of the steps in upgrading rancher), ran this command:
rke etcd snapshot-save --name rancher_upgrade_backup.db --config rancher-cluster.yml
Output was this:
FATA Unsupported Docker version found [19.03.1], supported versions are [1.11.x 1.12.x 1.13.x 17.03.x 17.06.x 17.09.x 18.06.x 18.09.x]
Everything appears to be working however…
Even the recurring snapshots are working (atleast the file is getting generated).
My question is: should I downgrade / roll back docker to 18.x or something else?
Any ideas on when 19.x will be supported?
