Since I haven't logged into the Portainer system for a long time, I forgot the login password and tried many common passwords without success, so I had no choice but to reset the password.
1. Stop the Portainer Container#
Check the container ID and COMMAND to stop the container.
docker ps -a
Stop the container.
docker stop portainer
2. Find the Path of Volume Data on the Host#
docker inspect portainer # Find "Source":
find / -name portainer.key
/var/lib/docker/volumes/portainer_data/_data/ This path is needed when using the reset command.
3. Reset Password#
docker run --rm -v /var/lib/docker/volumes/portainer_data/_data:/data portainer/helper-reset-password # Replace source address
docker run --rm -v /var/lib/docker/volumes/0e304ccd0c1c26495c60e458a02997f0568719b6df8388ae82418915d11cad9e/_data:/data portainer/helper-reset-password # Local address
The output contains the username and password; remember to copy the password, as it will be needed when changing the user password.
4. Start the Container#
systemctl start docker
Check if the container started successfully.
docker ps -a
5. Log in to Portainer#
Portainer login address http://IP:9000, username admin, password is the long string of password after the reset is completed.
Click the user to reset the password; the current password is the long string of password after the reset is completed. After entering the new password twice, click to change the password. Refresh and log in again to verify if the modified password is correct, then remember the password.
