A general purpose migration tool built around Task runner, where migration files are simply Task targets.
Define "sql migration" like Task files in a versions directory. These
Task files will be executed in lexicographical order. Tasks which
were successfully executed will not be executed again.
Intended to aid in the upgrading of embeded systems Kubernetes' versions.
Create a migration file 1_delete_prom_for_upgrade.yaml:
---
version: "3"
vars:
K3S_VERSION:
sh: k3d version | grep k3s | awk '{print $3}'
TO_K3S_VERSION: v1.23.1-k3s1
tasks:
up:
cmds:
- kubectl delete deployment kube-prometheus-stack-kube-state-metrics -n monitoring
- kubectl delete ds kube-prometheus-stack-prometheus-node-exporter -n monitoring
preconditions:
- sh: "[ {{ .K3S_VERSION }} == {{ .TO_K3S_VERSION }} ]"
