IV. How to View Logs for a Docker Container
- As of June 2014 Docker has officially released v1.0.0.
- These instructions are intended for listing and attaching to Docker containers.
- I’ll be working from a Liquid Web Core Managed CentOS 6.6 server (or CentOS 7, Ubuntu 14.04 LTS, Fedora 20, Fedora 21), and I’ll be logged in as root.
- I have one Docker container running.
First we’ll list which containers we have running:
Your result should look similar to this:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
9c09acd48a25 fedora:20 /bin/bash 55 minutes ago Up 53 minutes furious_heisenberg
To list all local containers use -a option:
docker ps -a
It is some times handy to view the latest created container, including non-running containers. Simply use the -l option:
docker ps -l
To attach to a specific container you must have the Container ID. In this case, we’ll attach to the container with the ID 9c09acd48a25 :
docker attach 9c09acd48a25
Continue through this series of tutorials to configuring your container, and committing the changes to create a Docker image.
