How to update the Pgadmin4 docker image without losing any the user's information in the folder/var/lib/pgadmin?

Answer 1

1. Pull the latest docker image

2. Stop the running container

   sudo docker stop pgadmin

3. Remove existing container

   sudo docker rm pgadmin

4. Deploy/Run the latest images

   sudo docker run --name pgadmin -p 80:80 -v /var/lib/pgadmin:/var/lib/pgadmin -e 'PGADMIN_DEFAULT_EMAIL=m.thirumal@hotmail.com' -e 'PGADMIN_DEFAULT_PASSWORD=thirumal' -d dpage/pgadmin4

   or the below command for reverse proxy with ngnix

Answer 2

The choosen answer is correct, but if you doesn't have any volume for your starting image yet you also have to do:

sudo docker cp name_of_your_image:/var/lib/pgadmin /var/lib/pgadmin

and

sudo chown -R 5050:5050 /var/lib/pgadmin

Answer 3

I use a docker named volume to permanently store the /var/lib/pgadmin folder. Updating pgadmin's version then just requires changing the image name in my docker-compose.yml.

version: '3.7'
services:
  pgadmin:
    container_name: pgadmin
    image: dpage/pgadmin4:7.3
    restart: always
    env_file:
      - ../pgadmin.env
    volumes:
      - my-pgadmin-volume:/var/lib/pgadmin
    ports:
      - 5050:80
