Rename Docker Volume on Docker Desktop

Is it possible to rename a docker volume? I want to change the volume names of the existing container. I see that config.json and hostconfig.json has the volume details in it.

docker run -di -p 8083:443 -v app_main_db_test_1:/var/lib/pgsql/data  -v app_main_conf_test_1:/var/www/ ubuntu

I want to change app_main_db_test_1 to app_main_db and app_main_conf_test_1 to app_main_conf

    Figured it out. Thanks to this github post.

    # Create new Volume for DB and copy files from old volume
docker volume create --name app_main_db 
docker run --rm -it -v app_main_db_test_1:/from -v app_main_db:/to alpine ash -c "cd /from ; cp -av . /to"

# Create new Volume for conf and copy files from old volume
docker volume create --name app_main_conf
docker run --rm -it -v app_main_conf_test_1:/from -v app_main_conf:/to alpine ash -c "cd /from ; cp -av . /to"


# Start the container using new volumes
docker run -di -p 8083:443 -v app_main_db:/var/lib/pgsql/data  -v app_main_conf:/var/www/ ubuntu

# Delete old volumes
docker volume rm app_main_db_test_1
docker volume rm app_main_conf_test_1

    as far as i know there are no ways of renaming docker volume so far. There is an open github issue, which indicates there is no solution to the topic yet.

    But there are a few useful ways how to do so. Since you are saying you use Docker Desktop you could check this comment:

    docker volume create --name <new_volume>
docker run --rm -it -v <old_volume>:/from -v <new_volume>:/to alpine ash -c "cd /from ; cp -av . /to"
docker volume rm <old_volume>

    Which should do exactly what you are planning to do.

    Please don’t try this on a production machine, however on my dev machine (ubuntu), i had two containers:

    docker volume ls
DRIVER    VOLUME NAME
local     v1_sail-mysql
local     v2_sail-mysql

    I wanted to switch volumes like this

    mysql_1 -> v1_sail-mysql (originally v2_sail-mysql)
mysql_2 -> v2_sail-mysql (originally v1_sail-mysql)

    My docker volumes are located in /home/docker/volumes, in your case it might be /var/lib/docker/volumes

    I just renamed the volumes

    mv v1_sail-mysql v1_sail-mysql-tmp
mv v2_sail-mysql v1_sail-mysql
mv v1_sail-mysql-tmp v2_sail-mysql

    Restarted the containers which indeed switch the containers
