Update July 1st 2019  docker-compose logs  lt name-of-service gt    From the documentation      Usage  logs  options   SERVICE          Options       --no-color          Produce monochrome output       -f  --follow        Follow log output       -t  --timestamps    Show timestamps       --tail  all         Number of lines to show from the end of the logs                       for each container    See docker logs  You can start Docker compose in detached mode and attach yourself to the logs of all container later  If you re done watching logs you can detach yourself from the logs output without shutting down your services    Use docker-compose up -d to start all services in detached mode  -d   you won t see any logs in detached mode  Use docker-compose logs -f -t to attach yourself to the logs of all running services  whereas -f means you follow the log output and the -t option gives you timestamps  See Docker reference  Use Ctrl   z or Ctrl   c to detach yourself from the log output without shutting down your running containers   If you re interested in logs of a single container you can use the docker keyword instead    Use docker logs -t -f  lt name-of-service gt      Save the output  To save the output to a file you add the following to your logs command    docker-compose logs -f -t  gt  gt  myDockerCompose log

Unfortunately we need to run docker-compose logs separately from docker-compose run  In order to get this to work reliably we need to suppress the docker-compose run exit status then redirect the log and exit with the right status     bin bash set -euo pipefail docker-compose run app   tee app log    failed yes docker-compose logs --no-color  gt  docker-compose log    -z  quot   failed -  quot        exit 1

If you want to see output logs from all the services in your terminal    docker-compose logs -t -f --tail  lt no of lines gt        Eg       Say you would like to log output of last 5 lines from all service      docker-compose logs -t -f --tail 5   If you wish to log output from specific services then it can be done as below    docker-compose logs -t -f --tail  lt no of lines gt   lt name-of-service1 gt   lt name-of-service2 gt       lt name-of-service N gt       Usage       Eg  say you have API and portal services then you can do   something like below        docker-compose logs -t -f --tail 5 portal api      Where 5 represents last 5 lines from both logs    Ref  https   docs docker com v17 09 engine admin logging view container logs
