Docker的Ansible自动化应用
解决国内无法下载镜像问题
国内的服务器无法正常下载仓库的镜像了,只能到其他地区下载,再推送到阿里的镜像,再下载
原来阿里的镜像构建是可以用的,现在也不能下载了
docker pull busybox
docker tag docker.io/library/busybox:latest registry.cn-hangzhou.aliyuncs.com/k8s-a/ingress-nginx:v1.3.0
docker push registry.cn-hangzhou.aliyuncs.com/k8s-a/ingress-nginx:v1.3.0
Dockerfile 文件
# 创建Docke容器模板
FROM registry.cn-hangzhou.aliyuncs.com/k8s-a/ingress-nginx:v1.3.0

# 容器启动时运行的命令
CMD ["/bin/ping","www.baidu.com"]
构建镜像
docker build -t test .
运行容器
docker run -it --name=test test

使用Ansible创建和管理容器
Ansible 提供的 Docker 相关模块已经集成在 community.docker 集合中，而不是直接通过单个 docker 模块
默认情况下，Ansible 会将集合安装在用户的本地目录 ~/.ansible/collections/ 下。如果你需要安装到特定路径，可以使用 -p 参数指定路径
ansible-galaxy collection install community.docker
#查看docker模块
ansible-doc -l | grep docker
查看安装模块位置
