Re: pgadmin4 container install: volume mapping

Hi list,

I have been using the docker container install of pgAdmin4 for about a year and half, during which time I tried several times trying to make volume mapping work, to no avail.

Yes, the docker installation is very clean and simple.  But I just could not make volume mapping to work so that script files saved can be accessed easily, and server connections or any session related history etc. can be preserved when updating to use latest container images.  I hope someone can provide a pointer or two to help me.

Here is what I used to create the instance

docker run --name "pgadmin4.21" \ 

-p 5050:80 \ 

-e 'PGADMIN_DEFAULT_EMAIL=pgadmin@example.com' \ 

-e 'PGADMIN_DEFAULT_PASSWORD=123456' \ 

-d dpage/pgadmin4 \ 

-v /opt/pgadmin_session:/var/lib/pgadmin \ 

-v /opt/pgadmin_config:/pgadmin4 

Docker Inspection shows the container having

            "Env": [

                "PGADMIN_DEFAULT_EMAIL=pgadmin@example.com",

                "PGADMIN_DEFAULT_PASSWORD=123456",

                "PATH=/usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin",

                "LANG=C.UTF-8",

                "GPG_KEY=0D96DF4D4110E5C43FBFB17F2D347EA6AA65421D",

                "PYTHON_VERSION=3.7.7",

                "PYTHON_PIP_VERSION=20.0.2",

                "PYTHON_GET_PIP_URL=https://github.com/pypa/get-pip/raw/d59197a3c169cef378a22428a3fa99d33e080a5d/get-pip.py",

                "PYTHON_GET_PIP_SHA256=421ac1d44c0cf9730a088e337867d974b91bdce4ea2636099275071878cc189e",

                "PYTHONPATH=/pgadmin4"

            ],

            "Cmd": [

                "-v",

                "/opt/pgadmin_session:/var/lib/pgadmin",

                "-v",

                "/opt/pgadmin_config:/pgadmin4"

            ],

Before I start the container instance, I made sure the folders were accessible

sudo mkdir /opt/pgadmin_session 

sudo mkdir /opt/pgadmin_config 

sudo chown 5050:5050  /opt/pgadmin_session 

sudo chown 5050:5050  /opt/pgadmin_config 

sudo chmod -R 777 /opt/pgadmin_session 

sudo chmod -R 777 /opt/pgadmin_config
