Cannot deploy agent to Charmed PostgreSQL VM ARM charm (as subordinated) #54

Closed taurus-forever closed 7 months ago

taurus-forever commented 9 months ago

Bug Description

Hi,

As a part of 24.04 sprint we are testing Charmed PostgreSQL ARM build with COS and currently it crashes due to the lack of ARM snap (see the full log below):

charms.operator_libs_linux.v2.snap.SnapNotFoundError: Snap 'grafana-agent' not found!

AFAIK, ARM support is not yet implemented for VM grafana agent => it is a bugreport to add it. Tnx!

To Reproduce

juju deploy postgresql --channel 14/edge --config profile=testing --constraints arch=arm64 --series jammy
git clone https://github.com/canonical/grafana-agent-operator/ && cd grafana-agent-operator
sed -i 's/amd64/arm64/' charmcraft.yaml 
charmcraft pack
juju deploy ./grafana-agent_ubuntu-22.04-arm64.charm
juju relate postgresql:cos-agent grafana-agent

We now support ARM for the grafana-agent snap!

Please try again, and if the issue is still there feel free to re-open the issue :)
