Reset Portainer password

Zitat von rs2112sr

Hello and sorry for the noob question!!

I'm trying to reset the Portainer password, but without success, since I don't know how to find the "bind-mount/volume for the data volume".

Thank you for the patience.

Using the guide from this link: github

Code

# stop the existing Portainer container
docker container stop portainer

# run the helper using the same bind-mount/volume for the data volume
docker run --rm -v portainer_data:/data portainer/helper-reset-password
2020/06/04 00:13:58 Password succesfully updated for user: admin
2020/06/04 00:13:58 Use the following password to login: &_4#\3^5V8vLTd)E"NWiJBs26G*9HPl1

# restart portainer and use the password above to login
docker container start portainer

Did you install portainer with the button in OMV? i assume so.

If you don't know the name of your portainer container, you should be able to find it with this command:

docker ps | grep port

Output (my container is named "portainer"). I think the button in OMV names the container portainer-ce, but don't hold me to it.

root@openmediavault:~# docker ps | grep port
1f7d22a9a8a5   portainer/portainer-ce:linux-amd64-2.16.0       "/portainer"             3 days ago     Up 3 days             0.0.0.0:8000->8000/tcp, :::8000->8000/tcp, 0.0.0.0:9000->9000/tcp, :::9000->9000/tcp, 9443/tcp                portainer
root@openmediavault:~# 

Then to get your volume (again, assuming your container is named portainer)

docker inspect portainer | grep /data

So my docker volume is "/NAS/AppData/portainer"

root@openmediavault:~# docker inspect portainer | grep /data
                "/NAS/AppData/portainer:/data:rw",
                "Destination": "/data",
                "/data": {}
root@openmediavault:~#

if you know actual password, you can change it from Portainer webGUI.

If you do not know actual password, you can uninstall portainer and delete docker volume, then reinstall portainer and start from scratch configuring a new password for first time.

Only thing that sucks about doing it that way, is if you use a lot of stacks.. I'm pretty sure you're going to lose the ability to edit them. (I've got about 25)
