pgadmin4 container install: volume mapping not working

[Bo Guo <bo.guo@xxxxxxxxxxxxx>]

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, in vein.

Yes, the docker installation is very clean and simple.  But I just could not make volume mapping to work so that script file saved can be accessed easily and server connections or any session related history etc. can be preserved when updating to use the 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@xxxxxxxxxxx' \ 
> -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@xxxxxxxxxxx",
                "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
>

Cheers!
