How do you list volumes in docker containers

Question

When using docker images from registries  I often need to see the volumes created by the image s containers   Note  I m using docker version 1 3 2 on Red Hat 7   Example  The postgres official image from the Docker Registry has a volume configured for containers at  var lib postgresql data   What s the most succinct command to show the volume at  var lib postgresql data in a postgres container

From Docker Documentation  here  Mounts Names of the volumes mounted in this container   docker ps -a --no-trunc --format  quot    ID   t   Names   t   Mounts   quot  should work

Show names and mount point destinations of volumes used by a container   docker container inspect    -f     range  Mounts       Name        Destination       end        CONTAINER ID OR NAME   This is compatible with Docker 1 13

With docker 1 10  you now have new commands for data-volume containers   for regular containers  see the next section  for docker 1 8      docker volume ls docker volume inspect      With docker 1 8 1  August 2015   a docker inspect -f      Volumes     containerid would be empty   You now need to check Mounts  which is a list of mounted paths like       Mounts                          Name    7ced22ebb63b78823f71cf33f9a7e1915abe4595fcd4f067084f7c4e8cc1afa2               Source     mnt sda1 var lib docker volumes 7ced22ebb63b78823f71cf33f9a7e1915abe4595fcd4f067084f7c4e8cc1afa2  data               Destination     home git repositories               Driver    local               Mode                   RW   true                  If you want the path of the first mount  for instance   that would be  using index 0    docker inspect -f      index  Mounts 0  Source     containerid   As Mike Mitterer comments below      Pretty print the whole thing      docker inspect -f     json  Mounts     containerid   python -m json tool    Or  as commented by Mitja  use the jq command   docker inspect -f     json  Mounts     containerid   jq

I actually googled this  and found my own answer    My memory these days    And for those that dont know about it commandlinefu is a nice place to find and publish these kinda snippets   List docker volumes by container   docker ps -a --format      ID       xargs -I    docker inspect -f      Name      printf   n       range  Mounts      printf   n t        Type       if eq  Type  bind        Source      end       Name      gt      Destination      end      printf   n           Example output   root jac007-truserv-jhb1-001   gitlab   docker ps -a --format      ID       xargs -I    docker inspect -f      Name      printf   n       range  Mounts      printf   n t        Type       if eq  Type  bind        Source      end       Name      gt      Destination      end      printf   n          gitlab server 1      volume gitlab-data   gt   var opt gitlab     volume gitlab-config   gt   etc gitlab     volume gitlab-logs   gt   var log gitlab   gitlab runner 1      bind  var run docker sock   gt   var run docker sock     volume gitlab-runner-config   gt   etc gitlab-runner     volume 35b5ea874432f55a26c769e1cdb1ee3f06f78759e6f302e3c4b4aa40f3a495aa   gt   home gitlab-runner

You can get information about which volumes were specifically baked into the container by inspecting the container and looking in the JSON output and comparing a couple of the fields  When you run docker inspect myContainer  the Volumes and VolumesRW fields give you information about ALL of the volumes mounted inside a container  including volumes mounted in both the Dockerfile with the VOLUME directive  and on the command line with the docker run -v command  However  you can isolate which volumes were mounted in the container using the docker run -v command by checking for the HostConfig Binds field in the docker inspect JSON output  To clarify  this HostConfig Binds field tells you which volumes were mounted specifically in your docker run command with the -v option  So if you cross-reference this field with the Volumes field  you will be able to determine which volumes were baked into the container using VOLUME directives in the Dockerfile   A grep could accomplish this like     docker inspect myContainer   grep -C2 Binds      HostConfig          Binds               var docker docker-registry config  registry           And       docker inspect myContainer   grep -C3 -e  Volumes          Volumes           data     var lib docker            config     var lib docker            registry     var docker docker-registry config    And in my example  you can see I ve mounted  var docker docker-registry config into the container as  registry using the -v option in my docker run command  and I ve mounted the  data and  config volumes using the VOLUME directive in my Dockerfile  The container does not need to be running to get this information  but it needs to have been run at least one time in order to populate the HostConfig JSON output of your docker inspect command

if you want to list all the containers name with the relevant volumes that attached to each container you can try this   docker ps -q   xargs docker container inspect -f      Name        HostConfig Binds       example output       opt rundeck 1   opt var lib mysql  var lib mysql rw    var lib rundeck var storage  var lib rundeck var storage rw    opt var rundeck  ssh  var lib rundeck  ssh rw    opt etc rundeck  etc rundeck rw  var log rundeck  var log rundeck rw    opt rundeck-plugins  opt rundeck-plugins rw    opt var rundeck  var rundeck rw     opt rundeck 1 - container name       - volumes attached to the conatiner

Use docker ps to get the container id   Then docker inspect -f      Mounts     containerid  Example     terminal 1    docker run -it -v  tmp  tmp ubuntu 14 04  bin bash   terminal 2    docker ps

the Go language to implement the docker command tools   The docker inspect command without the -f format is quite verbose   Since it is JSON you could pipe it to python or nodejs and extract whatever

Useful variation for docker-compose users   docker-compose ps -q   xargs docker container inspect       -f     range  Mounts       Name        Destination       end        This will very neatly output parseable volume info  Example from my wordpress docker-compose   ubuntu core   docker-compose ps -q   xargs docker container inspect  -f     range  Mounts       Name        Destination       end      core wpdb  var lib mysql  core wpcode  code core wphtml  var www html    The output contains one line for each container  listing the volumes  and mount points  used  Alter the     Name        Destination    portion to output the info you would like    If you just want a simple list of volumes  one per line    docker-compose ps -q   xargs docker container inspect       -f     range  Mounts       Name       end            xargs -n 1 echo core wpdb core wpcode core wphtml   Great to generate a list of volumes to backup  I use this technique along with Blacklabelops Volumerize to backup all volumes used by all containers within a docker-compose  The docs for Volumerize don t call it out  but you don t need to use it in a persistent container or to use the built-in facilities for starting and stopping services  I prefer to leave critical operations such as backup and service control to the actual user  outside docker   My backups are triggered by the actual  non-docker  user account  and use docker-compose stop to stop services  backup all volumes in use  and finally docker-compose start to restart
