Software crisis averted.
PGADMIN4 Complete working instructions.
First I followed these instructions to download and install software
https://www.postgresql.org/download/linux/ubuntu/
only up to postgresql-server-dev-12. no further.
Then I went to this website by googling sudo apt-get install pgadmin4 apache
https://www.tecmint.com/install-pgadmin-debian-10/ although I have ubuntu.
copied and pasted the following code changing the email and password.
To the one I put in when prompted for and while running command line sudo apt-get install pgadmin4 apache.
Also if run this command: systemctl status apache2 then you can 'q' out of it to continue.
THIS MAY NOT WORK: http://SERVER_IP/pgadmin4 OR http://localhost/pgadmin4
Don't forget to stop service apache server. sudo systemctl stop apache2 otherwise you will get a port clash with docker.
then I went to website https://www.pgadmin.org/docs/pgadmin4/latest/container_deployment.html
SO downloaded docker with snap. sudo snap install docker
sudo docker pull dpage/pgadmin4
sudo docker run -p 80:80 \
-e 'PGADMIN_DEFAULT_EMAIL=user@xxxxxxxxxx' \
-e 'PGADMIN_DEFAULT_PASSWORD=SuperSecret' \
-d dpage/pgadmin4
ran sudo docker
sudo docker run -p 80:80 -e 'PGADMIN_DEFAULT_EMAIL=zahidr1000@xxxxxxxxx' -e 'PGADMIN_DEFAULT_PASSWORD=*******' -d dpage/pgadmin4
Here is the KICKER. (not http://127.0.0.1/pgadmin4)
go to browser and type http://127.0.0.1 and you will see the blue login screen prompting you for the
above email and password.
That's it.
