gitlab-runner docker-compose安装使用

启动后登录容器注册，然后生成参数

问题解决：

1.docker in docker打包镜像报错，挂载socket

volumes = ["/cache", "/var/run/docker.sock:/var/run/docker.sock"]   

2. gitlab runner写k8s配置，其中变量的双引号很重要

.deploy_script: &deploy_script
  script:
    - whoami
    # - sleep 3600
    - mkdir /root/.kube/ -pv
    - echo "$KUBECONFIG_JOUBEI" > /root/.kube/config-joubei
    - cat /root/.kube/config-joubei
    - kubectl --kubeconfig=/root/.kube/config-joubei set image deployment/${DEPLOY_NAME} ${CONTAINER_NAME}=${REGISTRY_REGION_VPC}/${REGISTRY_NAMESPACE}/${REGISTRY_NAME}:${REGISTRY_VERSION} -n ${NAMESPACE}
    - kubectl --kubeconfig=/root/.kube/config-joubei -n ${NAMESPACE} rollout status --timeout=300s deploy/${DEPLOY_NAME} || { kubectl --kubeconfig=/root/.kube/config-joubei -n ${NAMESPACE} describe pod -lapp=${LABEL_APP}; exit 1; }
