在docker版本>= 1.8上使用单引号

docker inspect -f '{{ .Mounts }}' containerid

导致以下错误-

Template parsing error: template: :1: unclosed action

用双引号代替-

docker inspect -f "{{ .Mounts }}" <contained-id>

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.

grep可以像这样完成:

$ docker inspect myContainer | grep -C2 Binds
...
"HostConfig": {
    "Binds": [
        "/var/docker/docker-registry/config:/registry"
    ],

和…

$ docker inspect myContainer | grep -C3 -e "Volumes\":"
...
"Volumes": {
    "/data": "/var/lib/docker...",
    "/config": "/var/lib/docker...",
    "/registry": "/var/docker/docker-registry/config"

在我的例子中，你可以看到我使用docker run命令中的-v选项将/var/docker/docker-registry/config挂载到容器中作为/registry，并且我使用Dockerfile中的VOLUME指令挂载了/data和/config卷。容器不需要运行来获取这些信息，但它需要至少运行一次才能填充docker inspect命令的HostConfig JSON输出。

对docker-compose用户有用的变体:

docker-compose ps -q | xargs docker container inspect  \
   -f '{{ range .Mounts }}{{ .Name }}:{{ .Destination }} {{ end }}' 

这将非常整洁地输出可解析的音量信息。例子来自我的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 

每个容器的输出都包含一行，列出了使用的卷(和挂载点)。修改{{. name}}:{{. destination}}部分来输出你想要的信息。

如果您只想要一个简单的卷列表，则每行一个

$ 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.

这是我的版本，找到一个码头撰写挂载点。 在使用此备份卷时。

 # for Id in $(docker-compose -f ~/ida/ida.yml ps -q); do docker inspect -f '{{ (index .Mounts 0).Source }}' $Id; done
/data/volumes/ida_odoo-db-data/_data
/data/volumes/ida_odoo-web-data/_data

这是以前解决方案的组合。

打印所有容器及其Docker卷:

docker container inspect $(docker container ls -q) \
  -f '{{$container := .Name}}{{range .Mounts}}{{if eq .Type "volume"}}{{$container}} {{.Name}}{{"\n"}}{{end}}{{end}}' \
  | grep -v '^$'

下面是一行命令来获取正在运行的容器的卷信息:

for contId in `docker ps -q`; do echo "Container Name: "   `docker ps -f "id=$contId" | awk '{print $NF}' | grep -v NAMES`; echo "Container Volume: " `docker inspect -f '{{.Config.Volumes}}' $contId`; docker inspect -f '{{ json .Mounts }}' $contId  | jq '.[]';   printf "\n"; done

输出是:

root@ubuntu:/var/lib# for contId in `docker ps -q`; do echo "Container Name: "   `docker ps -f "id=$contId" | awk '{print $NF}' | grep -v NAMES`; echo "Container Volume: " `docker inspect -f '{{.Config.Volumes}}' $contId`; docker inspect -f '{{ json .Mounts }}' $contId  | jq '.[]';   printf "\n"; done
