From: sousaedu Date: Wed, 4 Nov 2020 15:13:35 +0000 (+0000) Subject: Refactoring LCM charm to use Operator Framework X-Git-Tag: release-v9.0-start~37 X-Git-Url: https://osm.etsi.org/gitweb/?p=osm%2Fdevops.git;a=commitdiff_plain;h=abe7321ec4e652cdb0f359169788a6c8ac9295f8 Refactoring LCM charm to use Operator Framework This refactoring work includes tests. Note 1: old charm is in lcm-k8s folder. Note 2: relation-departed is currently not tested because there is no function to remove a relation in the Testing Harness. There is currently one issue open and the Charmcraft team should provide feedback soon.
