K3s: Upgrade your Traefik ingress controller to version 2

2 min read

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:

# pwd /var/lib/rancher/k3s/server/static/charts # ls -lrt total 104 -rw------- 1 root root 27292 May 21 2021 traefik-1.81.0.tgz -rw------- 1 root root 914 Nov 21 17:19 traefik-crd-9.18.2.tgz -rw------- 1 root root 17008 Nov 21 17:19 traefik-9.18.2.tgz -rw------- 1 root root 914 Dec 3 07:14 traefik-crd-9.18.201.tgz -rw------- 1 root root 17041 Dec 3 07:14 traefik-9.18.201.tgz -rw------- 1 root root 17685 Dec 22 19:07 traefik-10.3.001.tgz -rw------- 1 root root 7396 Dec 22 19:07 traefik-crd-10.3.001.tgz

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.

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

$ helm history pet2cattle REVISION UPDATED STATUS CHART APP VERSION DESCRIPTION  60 Wed Dec 30 16:17:58 2020 superseded pet2cattle-1.7 2.8 Upgrade complete 61 Fri Jan 1 21:45:07 2021 superseded pet2cattle-2 3 Upgrade complete 62 Sat Jan 2 11:57:26 2021 superseded pet2cattle-2 3.1 Upgrade complete 63 Sat Jan 2 22:09:24 2021 superseded pet2cattle-2 3.2 Upgrade complete 64 Mon Jan 4 09:33:53 2021 superseded pet2cattle-2 3.3 Upgrade complete 65 Tue Jan 5 07:57:53 2021 superseded pet2cattle-2 3.4 Upgrade complete 66 Wed Jan 6 15:25:30 2021 superseded pet2cattle-2 3.5 Upgrade complete 67 Thu Jan 7 09:10:07 2021 superseded pet2cattle-2 3.6 Upgrade complete 68 Fri Jan 8 08:17:56 2021 superseded pet2cattle-2 3.7 Upgrade complete 69 Sat Jan 9 19:23:25 2021 deployed pet2cattle-2 3.8 Upgrade complete

Let's assume that the latest deployed versions is not working.
