I've been attempting to use Tekton to deploy some AWS infrastructure via Terraform but not having much success.
The pipeline clones a Github repo containing TF code , it then attempts to use the terraform-cli task to provision the AWS infrastructure. For initial testing I just want to perform the initial TF init and provision the AWS VPC.
Expected behaviour
- Clone Github Repo
- Perform Terraform Init
- Create the VPC using targeted TF apply
Actual Result
task terraform-init has failed: failed to create task run pod "my-infra-pipelinerun-terraform-init": Pod "my-infra-pipelinerun-terraform-init-pod" is invalid: spec.initContainers[1].name: Duplicate value: "step-init". Maybe missing or invalid Task default/terraform-cli pod for taskrun my-infra-pipelinerun-terraform-init not available yet Tasks Completed: 2 (Failed: 1, Cancelled 0), Skipped: 1
Steps to Reproduce the Problem
Prerequisites: Install Tekton command line tool, git-clone and terraform-cli
create this pipeline in Minikube
apiVersion: tekton.dev/v1beta1
kind: Pipeline
metadata:
name: my-infra-pipeline
spec:
description: Pipeline for TF deployment
params:
- name: repo-url
type: string
description: Git repository URL
- name: branch-name
type: string
description: The git branch
workspaces:
- name: tf-config
description: The workspace where the tf config code will be stored
tasks:
- name: clone-repo
taskRef:
name: git-clone
workspaces:
- name: output
workspace: tf-config
params:
- name: url
value: $(params.repo-url)
- name: revision
value: $(params.branch-name)
- name: terraform-init
runAfter: ["clone-repo"]
taskRef:
name: terraform-cli
workspaces:
- name: source
workspace: tf-config
params:
- name: terraform-secret

- name: ARGS

- name: ARGS
value:
- apply
- "-target=aws_vpc.vpc -auto-approve"
Run the pipeline by creating a pipelinerun resource in k8s
Review the logs > tkn pipelinerun logs my-tf-pipeline -a
Additional Information
Pipeline version: v0.35.1
