Rancher Gitlab Runner CI/CD

Rancher Gitlab Runner CI/CD

获取Kubernetes配置信息

Gitlab中添加Kubernetes集群

• CA Certificate 不需要填写
• RBAC-enabled cluster、 GitLab-managed cluster 不要勾选（坑）

示例

.gitlab-ci.yml 示例

image: docker:19.03

services:
   - name: docker:19.03-dind

variables:
   DOCKER_HOST: tcp://docker:2375
   # This will instruct Docker not to start over TLS.
   DOCKER_TLS_CERTDIR: ""

stages:
   - gradle-build
   - docker-build
   #  - review
   - deploy

gradle-build:
   stage: gradle-build
   image: gradle:6.8-jdk8
   cache:
      paths:
         - .gradle/wrapper
         - .gradle/caches
   before_script:
      - export GRADLE_USER_HOME=`pwd`/.gradle
   script:
      - gradle :provider-example-service:build -x test
   artifacts:
      paths:
         - ${PROJECT_JAR_PATH}
   # 只在develop分支生效
   only:
      - develop

docker-build:
   stage: docker-build
   script:
      - docker build -t ${HARBOR_HOST}/${HARBOR_PROJECT}/${CI_PROJECT_NAME}:latest .
      - docker tag ${HARBOR_HOST}/${HARBOR_PROJECT}/${CI_PROJECT_NAME}:latest ${HARBOR_HOST}/${HARBOR_PROJECT}/${CI_PROJECT_NAME}:${CI_PIPELINE_ID}
      - docker login ${HARBOR_HOST} -u ${HARBOR_USERNAME} -p ${HARBOR_PASSWORD}
      - docker push ${HARBOR_HOST}/${HARBOR_PROJECT}/${CI_PROJECT_NAME}:latest
      - docker push ${HARBOR_HOST}/${HARBOR_PROJECT}/${CI_PROJECT_NAME}:${CI_PIPELINE_ID}

kubernetes-deploy:
   stage: deploy
   image:
      name: bitnami/kubectl:1.2
   environment:
      name: development
      kubernetes:
         namespace: ${KUBE_NAMESPACE}
   script:
      - |
         cat deployment.yaml | \
         sed -e "s@{{POD_PORT}}@${PROJECT_PORT}@g" \
             -e "s@{{POD_NAME}}@${CI_PROJECT_NAME}@g" \
             -e "s@{{NAMESPACE}}@${KUBE_NAMESPACE}@g" \
             -e "s@{{IMAGE}}@${HARBOR_HOST}/${HARBOR_PROJECT}/${CI_PROJECT_NAME}:${CI_PIPELINE_ID}@g" \
             -e "s@{{IMAGE_PULL_SECRETS}}@${IMAGE_PULL_SECRETS}@g" | \
         kubectl apply -f -

• environment: name需与Gitlab中创建的Kubernetes cluster Environment scope相同
