to enable logs for docker containers
Hi Experts,
I am using docker containers, in my development environment. It is Ubuntu on AWS. I had built docker images and run docker containers.
when I try "docker ps" it displays all running docker containers. But not able to see the logs and application is not harvesting data(elastic search) from the application. I can see only few results there are nearly, 8 to 10 docker containers and I am able to see all the images running. I am not able the see the logs for all the containers. secondly, there are less results from the harvesters application.
How will I enable the logs for the containers? Please help me.
Kind Regards,
Bharath AK

Bharath,
For setting up docker image in aws machine you should install docker engine first in ubuntu server, later you can follow this link for setting the image from docker file.

Hi Prabin,
I had tried this command it changed the command prompt to container, when I try
docker exec -it 43583542fc10 /bin/bash it changed from root@ip-10-252-14-11:/home
to root@43583542fc10:/home/lm
where as going inside the with docker exec -it <containerId> bin/bash it goes to another command prompt. how can I see the logs?
With Many thanks,
Bharath AK

Hi Prabhin,
Thank you so much. I am able go inside container and ls all folders and see all inside that containers. I found there are no logs folder or file inside that folder, might be logs might not be generated by that application. I need one more clarification., What is cloud watch, there are logs inside the cloudwatch in AWS, whatz the difference between the logs generated by application vs logs in the cloud watch. Please throw some light over it.
With Many Thanks,
