本文主要介绍DockerNginx容器和Tomcat容器实现负载均衡和动静分离 *** 作，具有很好的参考价值。希望对大家有帮助。来和边肖一起看看吧。

下载Tomcat8映像

这个tomcat包含jdk，可以直接访问，它自己启动8080端口

如图所示访问Nginx80端口:

附加知识:Docker基本 *** 作容器删除映像并删除容器自启动

Docker容器自动重新启动设置

重启重启 *** 作系统后，我发现docker服务没有启动，容器也没有启动。重启后如何自动启动？

1。docker服务自动重新启动设置

[root@localhost~]#systemctl启用docker.service

2、docker容器自动启动设置

[root@localhost~]#dockerimages REPOSITORYTAGIMAGEIDCREATEDSIZE nginxlatest5a3221f0137b10monthsago126MB [root@localhost~]#dockerrun-itd-p80:80nginx 3e28c4b5c6256c0ba04666751e426987d848b7afeb9c59774d5e9831dc78e5ee [root@localhost~]#dockerrun-itd-p81:80nginx f0597c725fd6b7f4229aa9ab5de4a3cb29d09097a81dc8f64d1a60d469001379 [root@localhost~]#dockerportf0597c725fd6 80/tcp->0.0.0.0:81 [root@localhost~]#dockerps CONTAINERIDIMAGECOMMANDCREATEDSTATUSPORTSNAMES f0597c725fd6nginx"nginx-g'daemonof??30secondsagoUp29seconds0.0.0.0:81->80/tcpelastic_allen 3e28c4b5c625nginx"nginx-g'daemonof??35secondsagoUp33seconds0.0.0.0:80->80/tcptender_volhard

3。docker容器自动启动设置

[root@localhost~]#dockerupdate--restart=alwaysf0597c725fd63e28c4b5c625 f0597c725fd6 3e28c4b5c625 [root@localhost~]#reboot-hnow Connectionclosedbyforeignhost. [root@localhost~]#dockerps CONTAINERIDIMAGECOMMANDCREATEDSTATUSPORTSNAMES f0597c725fd6nginx"nginx-g'daemonof??13minutesagoUp2minutes0.0.0.0:81->80/tcpelastic_allen 3e28c4b5c625nginx"nginx-g'daemonof??13minutesagoUp2minutes0.0.0.0:80->80/tcptender_volhard

当主机中有许多镜像和容器需要重置时，您可以选择删除部分或全部镜像和容器。那么就需要下面的 *** 作。

1。删除容器

[root@localhost~]#dockerps-a CONTAINERIDIMAGECOMMANDCREATEDSTATUSPORTSNAMES 27c5c4d3cf86nginx"nginx-g'daemonof??2minutesagoUp2minutes0.0.0.0:80->80/tcpgracious_nash 61cccfe238a8nginx"nginx-g'daemonof??2minutesagoUp2minutes0.0.0.0:81->80/tcpdistracted_grothendieck [root@localhost~]#dockerps-aq 27c5c4d3cf86 61cccfe238a8

1)首先，您需要停止所有容器。

[root@localhost~]#dockerps-aq f0597c725fd6 3e28c4b5c625 8855c7777f83 466d2efe3dd9 20ca589b1a10 e5457b41cae6 314d1d01c941 [root@localhost~]#dockerstop$(dockerps-aq) f0597c725fd6 3e28c4b5c625 8855c7777f83 466d2efe3dd9 20ca589b1a10 e5457b41cae6 314d1d01c941 [root@localhost~]#dockerps CONTAINERIDIMAGECOMMANDCREATEDSTATUSPORTSNAMES

2)删除所有容器(仅在删除单个容器时将以下变量更改为图像id)

[root@localhost~]#dockerrm-f$(dockerps-aq) f0597c725fd6 3e28c4b5c625 8855c7777f83 466d2efe3dd9 20ca589b1a10 e5457b41cae6 314d1d01c941 [root@localhost~]#dockerps-aq [root@localhost~]#

2。删除镜像

1)检查主机中的镜像。

docker图像

2)删除具有指定id的镜像

dockerrmi<图像id>

3)删除所有图像

dockerrmi$(docker图片-q)

3.当要删除的映像与其他镜像相关且无法删除时。

您可以通过-f参数强制删除。

dockerrmi-f$(docker图片-q)
