补充知识:Docker 基础操作 容器自启动 删除镜像和删除容器
Docker容器自动重启设置
重启reboot操作系统后,发现docker 服务未启动,容器也未启动,怎么才能重启后自动启动呢
1、docker服务自动重启设置
[root@localhost ~]# systemctl enable docker.service
2、docker容器自动启动设置
[root@localhost ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest 5a3221f0137b 10 months ago 126MB [root@localhost ~]# docker run -itd -p 80:80 nginx 3e28c4b5c6256c0ba04666751e426987d848b7afeb9c59774d5e9831dc78e5ee [root@localhost ~]# docker run -itd -p 81:80 nginx f0597c725fd6b7f4229aa9ab5de4a3cb29d09097a81dc8f64d1a60d469001379 [root@localhost ~]# docker port f0597c725fd6 80/tcp -> 0.0.0.0:81 [root@localhost ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES f0597c725fd6 nginx "nginx -g 'daemon of"nginx -g 'daemon of"htmlcode">[root@localhost ~]# docker update --restart=always f0597c725fd6 3e28c4b5c625 f0597c725fd6 3e28c4b5c625 [root@localhost ~]# reboot -h now Connection closed by foreign host.

[root@localhost ~]# docker rm -f $(docker ps -aq) f0597c725fd6 3e28c4b5c625 8855c7777f83 466d2efe3dd9 20ca589b1a10 e5457b41cae6 314d1d01c941 [root@localhost ~]# docker ps -aq [root@localhost ~]#2、删除镜像
1)查看host中的镜像
docker images
2)删除指定id的镜像
docker rmi <image id>
3)删除全部的images
docker rmi $(docker images -q)
3、当要删除的iamges和其他的镜像有关联而无法删除时
可通过 -f 参数强制删除
docker rmi -f $(docker images -q)
以上这篇Docker Nginx容器和Tomcat容器实现负载均衡与动静分离操作就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持。
高通和谷歌日前宣布,推出首次面向搭载骁龙的Windows PC的优化版Chrome浏览器。
在对骁龙X Elite参考设计的初步测试中,全新的Chrome浏览器在Speedometer 2.1基准测试中实现了显著的性能提升。
预计在2024年年中之前,搭载骁龙X Elite计算平台的PC将面世。该浏览器的提前问世,有助于骁龙PC问世就获得满血表现。
谷歌高级副总裁Hiroshi Lockheimer表示,此次与高通的合作将有助于确保Chrome用户在当前ARM兼容的PC上获得最佳的浏览体验。
