Mounting multiple volumes on a docker container?

Question

I know I can mount a directory in my host on my container using something like

docker run -t -i -v '/on/my/host:/on/the/container' ubuntu /bin/bash

Is there a way to create more than one host-container pair? e.g. a comma-separated list, or pass in an array?

as I understand current state of docs terms, you cannot mount a volume (title of question), you certainly can have many bind mounts to host folders (that is what is asked for in body of question) — Alex Martian

do docker run -t -i \ -v '/on/my/host/test1:/on/the/container/test1' \ -v '/on/my/host/test2:/on/the/container/test2' \ ubuntu /bin/bash. — Charlie Parker

Pass multiple -v arguments.

For instance:

docker -v /on/my/host/1:/on/the/container/1 \ -v /on/my/host/2:/on/the/container/2 \ ...

Okay, so i'm doing this the exact same way but when i try calling the second one it says that it isn't found.

momal Over a year ago

docker run -v /home/usr/workspace/proj/WebContent/file/username:/mycode -v /home/usr/workspace/proj/WebContent/file:/tst gcc:4.9 sh -c 'cd mycode; gcc -o myapp ./mycode.c; cd tst; ./myapp < ./test.txt' This is my command, I'm trying to compile the mycode.c that is in the first volume, but give that same file an stdin from a different volume. How do I do it?

Does it always need absolute paths?

Charles Duffy Over a year ago

The destination must always be absolute. The source needs to be either an absolute path or the identifier for a named volume -- see docs.docker.com/engine/admin/volumes/volumes for docs on the latter.

this is working only for the second volume i am mapping... how can i map two volumes in the same run command assuming I can't use the docker file only run command

Docker now recommends migrating towards using --mount.

Multiple volume mounts are also explained in detail in the current Docker documentation.

From: https://docs.docker.com/storage/bind-mounts/

$ docker run -d \ -it \ --name devtest \ --mount type=bind,source="$(pwd)"/target,target=/app \ --mount type=bind,source="$(pwd)"/target,target=/app2,readonly,bind-propagation=rslave \ nginx:latest

Original older answer should still work; just trying to keep the answer aligned to current best known method.

It's worth adding the only reason Docker recommend migrating is because their research shows --mount is easier to use and it has more options. Using either -v or --mount is perfectly fine, this is down to your personal preference and needs.
what wrong with docker run -v /Users/brandomiranda/iit-term-synthesis:/home/bot/iit-term-synthesis \ -v /Users/brandomiranda/pycoq:/home/bot/pycoq \ -v /Users/brandomiranda/ultimate-utils:/home/bot/ultimate-utils \ -ti brandojazz/iit-term-synthesis:test bash?

You can use -v option multiple times in docker run command to mount multiple directory in container:

docker run -t -i \ -v '/on/my/host/test1:/on/the/container/test1' \ -v '/on/my/host/test2:/on/the/container/test2' \ ubuntu /bin/bash

Does this add anything to the preceding answer to the same effect?

Charlie Parker Over a year ago

love this answer! With a concrete thing that is essentially runable and a useful interactive demo.

You can have Read only or Read and Write only on the volume

docker -v /on/my/host/1:/on/the/container/1:ro \ docker -v /on/my/host/2:/on/the/container/2:rw \

which one is the default option?

lightbox142 Over a year ago

@HammadDar Pretty sure 'rw' is the default for volumes. You could try testing it out locally without specifying ':rw' or ':ro' at the end.

On Windows: if you had to mount two directories E:\data\dev & E:\data\dev2

Use:

docker run -v E:\data\dev:c:/downloads -v E:\data\dev2 c:/downloads2 -i --publish 1111:80 -P SomeBuiltContainerName:SomeLabel

I saw a comment asking if read-write or read-only was the default option; read-write is the default option. (making a post because I haven't enough rep to comment)

Per docker documentation, running the following:

docker run -d \ --name devtest \ --mount source=myvol2,target=/app \ nginx:latest

and then using docker inspect devtest and locating the "RW" option in the "Mounts" section of the output:

"Mounts": [ { "Type": "volume", "Source": "/var/lib/docker/volumes/myvol2/_data", "Destination": "/app", "Driver": "local", "Mode": "", "RW": true, "Propagation": "" } ],

lets us see that the default option lets the volume be both read- and write-able.

To set your volume as read-only (again per official documentation), add readonly after your source and destination tags:

docker run -d \ --name=nginxtest \ --mount source=nginx-vol,destination=/usr/share/nginx/html,readonly \ nginx:latest

Run docker inspect nginxtest and locate "Mounts":

"Mounts": [ { "Type": "volume", "Source": "/var/lib/docker/volumes/nginx-vol/_data", "Destination": "/usr/share/nginx/html", "Driver": "local", "Mode": "", "RW": false, "Propagation": "" } ],

(Note: I don't know why official documentation swaps between target and destination tags, but I am working under the assumption they can be used interchangeably.)

This does not provide an answer to the question. Once you have sufficient reputation you will be able to comment on any post; instead, provide answers that don't require clarification from the asker. - From Review

For a runable example:

docker run -v /Users/brandomiranda/iit-term-synthesis:/home/bot/iit-term-synthesis \ -v /Users/brandomiranda/pycoq:/home/bot/pycoq \ -v /Users/brandomiranda/ultimate-utils:/home/bot/ultimate-utils \ -ti brandojazz/iit-term-synthesis:test bash

but first do:

docker pull brandojazz/iit-term-synthesis:test

Joost van der Laan · Accepted Answer · 2014-03-26 22:08:35Z

Or you can do

docker run -v /var/volume1 -v /var/volume2 DATA busybox true

This is not what the OP is after. This creates a volume within the container and doesn't bind it on the host.

Joost van der Laan Over a year ago

You're right, should be: docker run -v /var/volume1:/container/volume1 -v /var/volume2:/container/volume2 DATA busybox true
