How to Stop,Start,and Remove Docker Containers to Manage their Lifecycle?| S-Logix

Description:
This task demonstrate how to control the lifecycle of Docker containers. Docker containers can be running, stopped, or removed. Stopping a container frees system resources temporarily, starting it resumes execution, and removing a container deletes it permanently from the system. These commands are essential for container management and cleanup.

Step 1 — List Running Containers
Description: Before stopping or removing a container, identify its CONTAINER ID or name.
Command:
```
docker ps
```
Shows all currently running containers.
Step 2 — Stop a Container
Description: Stop a running container gracefully.
Command:
```
docker stop <container_id_or_name>
```
Example:
```
docker stop testcopyfile
```
The container will stop, but still exists on the system.
Step 3 — Start a Container
Description: Restart a stopped container.
Command:
```
docker start <container_id_or_name>
```
Example:
```
docker start testcopyfile
```
The container resumes running with the previous state.
Step 4 — Remove a Container
Description: Delete a container permanently. Make sure it is stopped before removing.
Command:
```
docker rm <container_id_or_name>
```
Example:
```
docker rm testcopyfile
```
The container is deleted, freeing disk space.
Step 5 — Verify Removal
Description: Check that the container no longer exists.
Command:
```
docker ps -a
```
The container should no longer appear in the list.
If you want to force remove a running container, you can use:
```
docker rm -f <container_id_or_name>
```
Always make sure you don’t need the container’s data before removal.
