Docker重启容器失败:"已经在使用中“,但没有更多的码头图像 [英] docker restart container failed: "already in use", but there's no more docker image
问题描述
我首先得到了我的 nginx docker 镜像:
I first got my nginx docker image:
docker pull nginx
然后我开始它:
docker run -d -p 80:80 --name webserver nginx
然后我停止了:
docker stop webserver
然后我试图重新启动它:
Then I tried to restart it:
$docker run -d -p 80:80 --name webserver nginx
docker: Error response from daemon: Conflict. The container name "/webserver" is already in use by container 036a0bcd196c5b23431dcd9876cac62082063bf62a492145dd8a55141f4dfd74. You have to remove (or rename) that container to be able to reuse that name..
See 'docker run --help'.
嗯,这是一个错误.但实际上现在容器列表中什么都没有:
Well, it's an error. But in fact there's nothing in container list now:
docker container list
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
为什么我重启 nginx 镜像失败了?如何解决?
Why I restart nginx image failed? How to fix it?
推荐答案
是因为
- 您已使用
- name
switch. - 容器停止而未删除
你发现它停止了
docker ps -a
您可以简单地使用以下命令启动它:
You can simply start it using below command:
docker start webserver
替代方案如果要每次使用以下命令启动容器,
Alternatives If you want to start the container with below command each time,
docker run -d -p 80:80 --name webserver nginx
然后使用以下方法之一:
then use one of the following:
方法1:使用 - rm
switch i.e,一旦停止,容器会自动销毁
method 1: use --rm
switch i.e., container gets destroyed automatically as soon as it is stopped
docker run -d -p 80:80 --rm --name webserver nginx
方法2:在启动您当前使用的命令之前停止容器后明确地删除它.
method 2: remove it explicitly after stopping the container before starting the command that you are currently using.
docker stop <container name>
docker rm <container name>
