Checking Docker-Container-Logs when using Linux [Ubuntu Server 25.04]

                                            Docker Container Logs using LinuxOS

 Use Docker's logging command. The workflow is straightfoward. 

 First, identify the running container.

Run:

docker ps

 It should return the container NAME and CONTAINER ID. 

 Next, view the logs:

 

docker logs <container-name/ID-here>

That ^^^ cmd prints the full log output generated by the container.

 If the log output is large, stream it live (recommended for nodes like Kaspa):

docker logs -f <container NAME/ID here>

 This behaves like 

tail -f

and shows logs in real time.

To exit the live streams:

Ctrl + C

 That immediately returns you to the terminal prompt. The container keeps running; only the log view stops. 

to verify container is still running, 

Run:

docker ps

you should still see your container listed.

IMPORTANT DISTINCTION:

docker logs -f <container NAME/ID here>              =       Ctrl + C to exit

docker attach <container NAME/ID here>            =   Ctrl + P then Ctrl + Q

Ctrl + C is the correct move to exit the log view and exit programs in almost every case.

Additional operational flags that are useful:

Show only the most recent lines in log:

docker logs --tail 50 <container NAME/ID here> 

Include timestamps:

docker logs -t <container NAME/ID here>

Stream with timestamps:

docker logs -f -t <container NAME/ID here>    

example of entering code that i wrote with <container NAME/ID here> if kaspa-node is the container NAME/ID:

docker logs -f -t kaspa-node

 

If you forget the container name, run:

docker ps -a

that list all containers, including stopped ones, so you can target the correct log source.
