    yum install -y sshpass

UBUNTU

shell
apt-get  install sshpass

在每个服务器进行docker pull：

shell
#!/bin/bash
set -e
HOST_PASSWORD=r00tme
IMAGE_NAME_LIST=("192.168.50.179:80/ai_algorithm_kevink8s/fire_smoke_detect:V1.0" "192.168.50.179:80/ai_algorithm_kevink8s/smoking_detect:V1.0" "192.168.50.179:80/ai_algorithm_kevink8s/electronic_fence_test:V1.10" "192.168.50.179:80/ai_algorithm_kevink8s/eletric_fence_detect:V1.0")

for varip in ${K8SIP_LIST[@]};
do
    for varimage in ${IMAGE_NAME_LIST[@]};
    do
        sshpass -p ${HOST_PASSWORD} ssh -tt root@${varip} << EOF
docker pull ${varimage}
# exit
exit 0 # 退出远程连接
