Upgrade Image from v1.13.0 to v1.14.1 Using chart v2.1.0 fails error loading config from /etc/cortex/cortex.yaml: Error parsing config file: yaml: unmarshal errors about cortex-helm-chart

[nschad]

Upgrading Cortex helm chart from v1.7.0 to v2.1.0 that includes Cortex docker image v1.14.1 fails to upgrade. Using chart 2.1.0 with cortex image: v1.13.0/1/2 works as expected.

Yeah your config is wrong. The error is coming from cortex not the helm-chart. Make sure your config matches https://cortexmetrics.io/docs/configuration/configuration-file/

But shouldn't the helm chart be providing the correct values following the change from Cortex 1.13 to 1.14 and the helm chart builds out the /etc/cortex/cortex.yaml file. The upgrade guide doesn't show steps to go from 1.7 (Cortex 1.13.x) of the chart to 2.1.0 (Cortex 1.14.x) and changes required.

I'll close this as no changes required yourside. Thanks for taking a look.

Yes it does however you need to use --reset-values otherwise old values persist between upgrades.
