Prepare the integration plan cicd Or go through the traditional jenkins github spinnaker These kinds of integration . First, build a basic environment . From jenkins Here we go

tar zxvf jenkins-3.3.0.tgz

3. helm install jenkins To designate namespace

3.1. Normal installation process

kubectl create ns kube-ops
helm install -f values.yaml jenkins  jenkins/jenkins -n kube-ops

3.2. Installing int Download plug-ins waiting for too long

Downloading plug-ins is a mess , Can't wait for time to value.yaml The process of installing plug-ins in the file is commented out .

Comment out install Install the plug-in manually behind

image.png

I commented it out and deleted it helm The deployment process has been restarted .

helm delete jenkins -n kube-ops
helm install -f values.yaml jenkins  jenkins/jenkins -n kube-ops

As expected, the comment is deleted and the system is started directly

4. Some things after initialization

4.1. wait for pod Initialization startup complete

4.2 The initialization password is log Search for

Look for the password in the traditional way first ：

kubectl logs -f jenkins-0 jenkins -n kube-ops

Well, the password isn't there log Medium

4.3. Get it right jenkins The way of initial password secret

printf $(kubectl get secret --namespace kube-ops jenkins -o jsonpath="{.data.jenkins-admin-password}" | base64 --decode);echo

5. traefik agent jenkins application

（https://www.yuque.com/duiniwukenaihe/ehb02i/odflm7 The way of construction and agency has been indicated above ）

Still used to ingressroute agent jenkins

cat jenkins-ingress.yaml

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  namespace: kube-ops
  name: jenkins-http
spec:
  entryPoints:
    - web
  routes:
    - match: Host(`jenkins.saynaihe.com`)
      kind: Rule
      services:
        - name: jenkins
          port: 8080

kubectl apply -f jenkins-ingress.yaml

6. web visit jenkins application

6.1. land jenkins web

what I didn't enter the account and password ？ I don't know why I can log in for the first time after initialization without a password .......

6.2 Change security settings , Users are not allowed to log in anonymously

With the idea of trying, I drove into above 4.3 What I got in step key ok Went in. .....

Here is a simple record of the application installation process , Concrete jenkins libraries pipeline and kubernetes spinnaker gitlab All the environments such as the integration of have been built and written together .
