During the section we'll install build-and-deploy pipeline, which triggers build and deploy tasks.
The build-and-deploy pipeline triggers the tasks in series, waiting first for build to finish and then it (re)deploys the app.
Before starting make sure you have the following:
- Kubernetes: kubernetes cluster up and running.
- Tekton: tekton installed.
- Build Task: Build task installed.
- Deploy Task: Deploy task installed.
- tkn: A CLI for interacting with Tekton.
Apply build-and-deploy-pipeline.yaml resource:
❯ kubectl apply -f tekton/3.pipelines/build-and-deploy-pipeline.yaml
pipeline.tekton.dev/build-and-deploy createdList the installed pipelines:
❯ tkn pipeline list
NAME AGE LAST RUN STARTED DURATION STATUS
build-and-deploy 23 seconds ago --- --- --- ---To verify our build-and-deploy pipeline we'll deploy our app on tekton-tutorial namespace.
Let's start the build-and-deploy pipeline with param namespace:tekton-tutorial and the rest with default values:
❯ tkn pipeline start build-and-deploy -p namespace=tekton-tutorial -p contextDir=. --showlog
