2.查看本地已有镜像
docker images
[root@localhost sysctl.d]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
3.拉取镜像
docker pull tomcat:8 ##version
[root@localhost sysctl.d]# docker pull tomcat:8 Trying to pull repository docker.io/library/tomcat ... 8: Pulling from docker.io/library/tomcat 22dbe790f715: Pull complete 0250231711a0: Pull complete 6fba9447437b: Pull complete 4afad9c4aba6: Pull complete 12fce9923c9d: Pull complete 0dd81083d77e: Pull complete 4c2afc6ff72d: Pull complete a62332a260f5: Pull complete 96dfb5ad080f: Pull complete 782f63228ce1: Pull complete d610fffe30ad: Pull complete Digest: sha256:aacce4e5ca37a3b8241c544deffd65f4cafbfb1a2fb2066f97621253c34f7dc4 Status: Downloaded newer image for docker.io/tomcat:8 [root@localhost sysctl.d]#
验证
docker images
[root@localhost sysctl.d]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/tomcat 8 dd6ff929584a 2 weeks ago 463 MB [root@localhost sysctl.d]#
4.启动tomcat
docker run -d -p 8080:8080 tomcat ####前者是外部访问端口，后者是容器内映射端口
如下命令可后台启动tomcat
-d: 后台运行容器，并返回容器ID；
-i: 以交互模式运行容器，通常与 -t 同时使用；
-t: 为容器重新分配一个伪输入终端，通常与 -i 同时使用；
[root@localhost sysctl.d]# docker run -d -p 8080:8080 tomcat Unable to find image 'tomcat:latest' locally Trying to pull repository docker.io/library/tomcat ... latest: Pulling from docker.io/library/tomcat Digest: sha256:aacce4e5ca37a3b8241c544deffd65f4cafbfb1a2fb2066f97621253c34f7dc4 Status: Downloaded newer image for docker.io/tomcat:latest 6a3c7c96df932566cc24cf7811ba774eb4c3f59f498ffc79d9f576ba2c589d04
5.查看运行中的容器
[root@localhost sysctl.d]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 6a3c7c96df93 tomcat "catalina.sh run" 22 seconds ago Up 20 seconds 0.0.0.0:8080->8080/tcp youthful_carson [root@localhost sysctl.d]# cd
