If you have K3s' system-upgrade-controller installed you might have noticed how charts appear under /var/lib/rancher/k3s/server/static/charts but your traefik Ingress controller is not being updated:

Terraform error: Provider configuration not present
2 min read
Due to the need to use the count keyword for making a resource optional I wanted to upgrade from terraform 0.12 to 0.13 but while doing so I found the following error:
Error: Provider configuration not present To work with module.jenkins.aws_iam_policy.jenkins_policy its original provider configuration at provider["registry.terraform.io/-/aws"] is required, but it has been removed. This occurs when a provider configuration is removed while objects created by that provider still exist in the state. Re-add the provider configuration to destroy module.jenkins.aws_iam_policy.jenkins_policy, after which you can remove the provider configuration again.07/04/2021

Rollback an upgrade using helm
3 min read
When we upgrade an application using helm it can always go something wrong so instead of upgrading to another version or uninstall / install the application, we can rollback to a previous version that we know it is working
Previously we already talked about the helm history command
