How to view Docker logs?

To view Docker logs for a specific container, you can use the docker logs command. Here’s how to do it:

Identify the Container: First, you need to know the name or ID of the container whose logs you want to view. You can list all running containers with:
```
docker ps
```
If you want to see all containers (including stopped ones), use:
```
docker ps -a
```
View Logs: Once you have the container name or ID, you can view its logs using the following command:
```
docker logs <container_id_or_name>
```
Replace <container_id_or_name> with the actual ID or name of your container.
Follow Logs in Real-Time: If you want to view the logs in real-time (similar to tail -f), you can use the -f option:
```
docker logs -f <container_id_or_name>
```
View Specific Number of Lines: If you want to see only the last few lines of the logs, you can use the --tail option:
```
docker logs --tail 100 <container_id_or_name>
```
This command will show the last 100 lines of logs.
View Logs with Timestamps: To include timestamps in the log output, use the --timestamps option:
```
docker logs --timestamps <container_id_or_name>
```

By using these commands, you can effectively view and monitor the logs of your Docker containers.
