v0.4.0-alphav1 release

on GitHub

Changes in v0.4.0-alphav1 since v0.3.8

Changes:

• The controller now deploys pods for each step of a terraform workflow which includes pods for terraform init, terraform plan, and trraform apply. Before the controller would create a Kubernetes Job that would perform the entire workflow by creating a single job.
• Pods that fail do not try again (the Job pod before would try again multiple times). To retry, the user deleted the failed pod and a new pod with the same configuration as the old pod launched by the controller.
• Pods now use a PersistentVolumeClaims that is handed from pod to pod to keep logs and terraform run data. PVCs must be allowed to be created by the controller and the Kubernetes cluster.

Breaking changes:

• prerunScript is equivilent to preInitScriptand the script runs as an init-container right before the terraform initcontainer
• postrunScript is equivilent to postInitScript and runs a new pod after terraform applycompletes
• applyOnApply no longer function as terraform is always executed
• applyOnUpdate no longer functions as terraform is always executed
• applyOnDeleteno longer function as terraform is always executed
• The tfstate is no longer added to a ConfigMap after terraform is completed. (This will be readded soon)
• Many enviroment variables within the runner Pods have changed. These are:
  • TFOPS_MAIN_MODULE -> TFO_MAIN_MODULE
  • NAMESPACE -> TFO_NAMESPACE
  • STACK_REPO-> TFO_MAIN_MODULE_REPO
  • STACK_REPO_HASH-> TFO_MAIN_MODULE_REPO_REF
  • STACK_REPO_SUBDIR-> TFO_MAIN_MODULE_REPO_SUBDIR
  • TFOPS_CONFIGMAP_PATH -> TFO_DOWNLOADS
  • INSTANCE_NAME -> TFO_RUNNER
