创建新Docker容器时出现“The container name “/xxx” is already in use by container xxxxxxxxxxx…”问题的解决办法

详细错误提示：
 /usr/bin/docker-current: Error response from daemon: Conflict. The container name “/xxx” is already in use by container e3274a72e8d62a0f3022d3201405ce586147b3031c1232452d001ee41fb9c938. You have to remove (or rename) that container to be able to reuse that name…

下面举例说明。

列出本地镜像：

docker images

REPOSITORY TAG IMAGE ID CREATED SIZE
 docker.io/tomcat 8.5.35 78b258e36eed 2 weeks ago 463 MB
 docker.io/tomcat latest 6759d91a032b 3 weeks ago 463 MB

创建新的容器：

docker run --name tomcat8080 -d -p 8080:8080 tomcat

/usr/bin/docker-current: Error response from daemon: Conflict. The container name “/tomcat8080” is already in use by container e3274a72e8d62a0f3022d3201405ce586147b3031c1232452d001ee41fb9c938. You have to remove (or rename) that container to be able to reuse that name…
 See ‘/usr/bin/docker-current run --help’.
 上面创建新容器出现了错误，提示：容器名被占用，须移除或重命名后才能使用这个容器名。

【解决办法】

先查看所有的容器

`docker ps -a`

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
 e3274a72e8d6 tomcat “catalina.sh run” 2 weeks ago Exited (130) 19 minutes ago tomcat8080
 看到了这个名为 “tomcat8080” 的容器，并且这个容器是非运行（Exited）状态。

注：“docker ps” 是查看当前运行的容器，“docker ps -a” 是查看所有容器（包括停止的）。

移除这个“tomcat8080”容器

`docker rm e3274a72e8d6`

e3274a72e8d6 再看，容器已经移除：

docker ps -a

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

然后再创建新容器

`docker run --name tomcat8080 -d -p 8080:8080 tomcat`

af52e9ac72c0393b5468cccf235ad70a7bf6a6b4ed30122b345b3758875d8911 新容器创建成功，并且是运行状态：

`docker ps -a`
