在 docker 容器上安装多个卷？

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? eg a comma-separated list, or pass in an array?

Answer 1

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 \
       ...

Answer 2

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.

Answer 3

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

Answer 4

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 \

Answer 5

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

Answer 6

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 perofficial 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.)

Answer 7

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

Answer 8

或者你可以做

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