K8S离线部署笔记-14-应用镜像迁移

配置DNS

vi /etc/hosts
# 本地虚拟机
10.10.50.204  registry.yourcompany.com

# 离线环境
10.10.51.77  registry.yourcompany.com

配置Docker允许HTTP

vi /etc/docker/daemon.json
{ "insecure-registries":["registry.yourcompany.com:5000"] }

镜像导出脚本

repo_save.sh

images=(
    tomcat/tomcat-oraclejdk8:8.5.50
)

for imageName in ${images[@]} ; do
    docker pull registry.yourcompany.com:5000/$imageName
    docker save registry.yourcompany.com:5000/$imageName > $imageName.tar
done

镜像导入脚本

repo_load.sh

images=(
    tomcat/tomcat-oraclejdk8:8.5.50
)

for imageName in ${images[@]} ; do
    docker load < $imageName.tar
    docker push registry.yourcompany.com:5000/$imageName
done

手工导出导入

# 导出
docker pull registry.yourcompany.com:5000/yourimage:2.2.0
docker save registry.yourcompany.com:5000/yourimage:2.2.0 > yourimage:2.2.0.tar

# 导入
docker load < yourimage:2.2.0.tar
docker push registry.yourcompany.com:5000/yourimage:2.2.0
