I made a site with docker very long time ago but I lost the password of portainer. So, I try to re-install to reset my Id and password, but it seems portainer keep containing my previous Id and password. I delete volume but is still not working.
I did like this.
step1. stop and delete container.
$sudo docker ps -a (to check container list) $sudo docker stop [container ID] $docker rm -v [container ID]
step2. delete image
$docker images (to check image ID) $docker rmi [image ID]
step3. delete volume
$docker volume rm portainer_data
step4. re-install portainer
$docker run -d -p 9000:9000 --name portainer --restart always -v /var/run/docker.sock:/var/run/docker.sock -v/data/portainer/data:/data portainer/portainer
when I try to access to portainer, still asking last ID and password.
