108	# 3. 进入容器排查
109	docker exec -it container_name sh
110
111	# 4. 查看进程
112	docker top container_name
113	```
114
115	### 场景 2：容器无法启动
116	```bash
117	# 查看退出原因
118	docker inspect container_name \| jq '.[0].State.ExitCode'
119	docker inspect container_name \| jq '.[0].State.Error'
120
121	# 查看日志
122	docker logs container_name
123
124	# 以交互模式启动排查
125	docker run -it --entrypoint sh image_name
126	```
127
128	### 场景 3：批量操作
129	```bash
130	# 停止所有容器
