执行 docker run 命令遇到了以下错误
sudo docker run -d -p 3000:3000 --name node-app gemini/demo
FATA[0000] Error response from daemon: Conflict. The name "node-app" is already in use by container 55a8d2226ce2. You have to delete (or rename) that container to be able to reuse that name.
使用 docker ps 命令发现存在运行中的容器名字也叫 "node-app"。
docker ps -l
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
fd3c0c622af6 gemini/demo:latest "npm start" 18 minutes ago Up 18 minutes 0.0.0.0:3000->3000/tcp node-app
使用命令停止并删除这个容器就可以
docker kill fd3c0c622af6
docker rm fd3c0c622af6
知道原因后可以将以上操作简化为以下命令
docker kill $(docker ps -q); docker rm $(docker ps -a -q)
