How to see docker container logs

Introduction

If you are running your container in -d (detached mode) or by docker remote API, you will not see any logs in console. To access running docker image or container logs you need to use docker logs command.

In this tutorial, I will list out various commands to display logs

To see docker containers logs make sure that first of all, docker container is running you can check this by using

Once you have confirmed that docker container is up and running you can use following commands

  In this case, last 2500 lines will be displayed

  docker logs --tail 2500 ContainerName/ContainerID

  docker logs --tail 2500 ContainerName/ContainerID

• To see logs since particular date or timestamp

  docker logs --timestamps ContainerName/ContainerID

  Now use the timestamp which should be in format like this 2017-05-03T10:00:59.935397007Z and use it to display logs

  docker logs --since 2017-05-03 ContainerName/ContainerID
