昨天用这个命令
sudo docker run -d --name test1 busybox /bin/sh -c "while true; do sleep 3600; done"
我今天再用这一条命令就报错，

sudo docker run -d --name test1 busybox /bin/sh -c "while true; do sleep 3600; done"
报错信息
docker: Error response from daemon: Conflict. The container name “/test1” is already in use by container “62144633d4a1bbef4b023268022b3512245e43832728222dce90903ddc6c39ff”. You have to remove (or rename) that container to be able to reuse that name.
说明这个名字已占用，要删除后才能用这个名字
但是我想把愿来的test1这个container启动起来，要用什么命令？
