gitlab ci配合rancher2实现自动重新部署

之前都是通过gitlab ci去构建项目，生成镜像上传到docker仓库，然后手动去重新部署rancher上的项目。最近研究了下通过调用rancher的api来自动重新部署。  
rancher2和1.6又很大区别，没有官方的api来实现，所以我谷歌了很久，基本现在有2种实现实现方法:  
1.通过diemscott/rancher-cli-k8s:v2.0.2镜像，使用kubectl来实现更新

RANCHER_SERVER_URL=https://rancher.example.com
    RANCHER_API_TOKEN="token-sd5kk:d27nrsstx6z5blxgkmspqv94tzkptnrpj7rkcrt7vtxt28tvw4djxp"
    
    deploy:
      stage: deploy
      image: diemscott/rancher-cli-k8s:v2.0.2
      script:
        - rancher login "$RANCHER_SERVER_URL" -t "$RANCHER_API_TOKEN"
        - rancher kubectl --namespace=default patch deployment nginx --type=strategic -p '{"spec":{"template":{"spec":{"containers":[{"name":"nginx","image": "nginx","env":[{"name":"FORCE_RESTART_AT","value":"$CI_PIPELINE_ID"}]}]}}}}'

但由于我们的rancher没有证书，导致这种方式跑不通，所以采用了第二种方式  
2.采用和rancher客户端一样的接口，来实现自动部署，脚本如下

#!/bin/bash
    
    programName=$1
    workspace=$2
    namespace=$3
    
    function update()
    {
        url='https://192.168.6.238:10443/v3/project/'${workspace}'/workloads/deployment:'${namespace}':'${programName}''
        #curl 请求
        pod_upgrade_body=$(curl -s "$url" -X GET -u "token" -H 'Accept-Encoding: gzip, deflate, br' -H 'Connection: keep-alive' -H 'Pragma: no-cache' -H 'Cache-Control: no-cache' -H 'content-type: application/json' -H 'accept: application/json'  --insecure 2>&1 | sed  "s/\"cattle\.io\/timestamp\"\:\"[0-9T:Z-]*\"/\"cattle\.io\/timestamp\":\"$(date -u +"%Y-%m-%dT%H:%M:%SZ")\"/g")
    
        echo "$pod_upgrade_body"
        curl 'https://192.168.6.238:10443/v3/project/'${workspace}'/workloads/deployment:'${namespace}':'${programName}'' -X PUT -u"token"  -H 'Accept-Encoding: gzip, deflate, br' -H 'Connection: keep-alive' -H 'Pragma: no-cache' -H 'Cache-Control: no-cache' -H 'content-type: application/json' -H 'accept: application/json' --data-binary "$pod_upgrade_body" --compressed --insecure
    }
    
    
    
    update

3.使用我上传到dockerhub上的镜像：  
具体说明可以去dockerhub上自行查看

deploy:
      stage: deploy
      image: lwydyby/rancher-gitlab-deploy:latest
      script:
        - bash  /data/update.sh ${PROJECT_NAME} ${RANCHER_WORKSPACE} ${RANCHER_NAMESPACE} ${RANCHER_IP} ${RANCHER_TOKEN}
