10:00 - 12:00 For those who can't connect with psql from the command line: In my case, I already had a Postgres server running on port 5432. It's because of pgAdmin 4. So always when I tried to connect to the "docker container", it connected to the incorrect server and not the docker one. I fixed it by changing the ports in the run command from 5432:5432 to 5433:5432. Also, change the psql command to "psql -h localhost -p 5433 -U postgres" and it should work. From now on I will avoid using the default port "5432". It took me 1-2 hours to understand the issue.

[@maxencepatouillere8883]

[@martinhecht455]

"psql -h localhost -p 5433 -U postgres" , can you please explain me why and what that is ? thanks in advance

[@amine52824]

thanks a lot man

[@amine52824]

@@TheMakeupmonika all he said was to change the container port to 5433 to avoid dependency issues, that command after is to connect to that container on the port we specified (5433)

This is perfect, great explanation! Docker makes it so much easier to tinker with databases without spending tons of time configuring a service.

[@adrianramirez4272]

Totally agree, containerization is the best !

[@limbu966]

For anyone on WINDOWS that could not connect to your postgres container from your host machine like he did in the video. Go to Control Panel>Programs and Files>Uninstall postgres>Individual component>postgres server . After that try to connect to your postgres container once again. It should work.

[@adrianramirez4272]

Thanks for the crystal clear explanation!

[@me360ot]

Suggestion at 11:00. You're highlighting the container port and not the localhost port. If a user wants a different local port, they should change the the first number, not the second.

[@amigoscode]

Yes you are right Thomas.

[@skysaville]

sure glad i saw this comment! my local version of postgres was already using port 5432 so i had to set the container port to a different port number (ex 5000:5432)

[@weplaSpetsnaz]

thank you for your comment I have the local postgres in same 5432 port and I have issues when I try to connect containerized postgres. Changed 5432:5432 to 5000:5432 and my issue is gone. Also I was trying connect directly with container name ( spring.datasource.url=jdbc:postgresql://mycontainername:5432/genel ) and that was keep giving sockettimeoutexception now right property is ( spring.datasource.url=jdbc:postgresql://localhost:5000/genel ) .Sorry for bad english I was stuck there 2 days.

[@abhishekagarwal2522]

Hey man! I have the following doubts : 1. If I'm using docker postgres image, then also i need to have postgres in my local machine? 2. I didn't understand when you connected local's postgres to docker's postgres. Like what is the point of that? 3. Please correct me if I am wrong but I have different postgres servers on different ports and my local postgres command can point to any of the server. If I am not explicitly telling the port then it uses postgres server by default which got installed while installing it on local (using homebrew, installer file) and if I explicitly mention the port number to connect with, it could be either the docker's postgres server or the local postgres server. Am I correct?

[@rolandsoftwareguy2515]

Thanks for this, it did help on the Docker side. However it seems although Postgres installed on my machine, it did not instal psql😕 Anyone had this? However, although I couldn't run any cli commands on my machine, pgadmin could "see" my databases, but I could run commands from the container while bashed ...could be by design ...although I'm coming from a windows background using a mac so there's probable a "Run as Administrator" type setting I need to use. I'm also using .Net so still some researching to do.

At 11:15 I get the error: psql -h localhost -p 5555 -U postgres psql: error: could not connect to server: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. Why could that be? I deliberately changed the port from 5432 to 5555 because I also have PSQL on my machine and it already uses that port.

A very good tutorial. I am still a bit confused though: what will happen if I load a big database dump to the postgres in the docker container (from bakcup .sql file for example), will docker adjust it's size automatically?

[@Pqoq]

I tried deploy postgresql 11 on docker: Backed up my 4GB database into 2GB .sql file using pg_dump. Sent the .sql file into docker container using docker cp. After that, I created an empty db and restored the 2GB .sql file into the empty db using psql cli inside the docker, not the psql at the host. After that, the size of my container was just the same as the host. I do not know whether the size is shrinkable (whatever it is called), maybe I could have restored the db inside the container using host's psql without copying the backup first, unnecessary perhaps. edit: container size was before restore:

[@vinceramces]

Great Tutorial! I was kind of lost at some point because I was using Windows and KiteMatic(Electron) App. I got lost at "psql -h localhost -p 5432 -U postgres" because Kitematic predefined another IP address for that container.

[@amigoscode]

Find the correct IP and the you should be able to psql into it

[@vinceramces]

@@amigoscode That was already solved, but thanks! my question was, is it okay to use KiteMap? I just followed the tutorial from pgAdmin and it exposes my password in environmental variables. I just want pgAdmin4 GUI in my local machine. it is somehow related to PostgreSQL but with a different platform to establish my own database schema. Thanks!

Your content is great and I am testimony of how it's accessible and straight forward to cope with it. I think you could do tutorial on frontend with Angular (essentials and advanced topics) and TypeScript (fundamentals and advanced topics) (type annotation, type inference, type assertion, arrow functions, interfaces, classes, objects, constructors, access modifiers, properties and modules). If it's possible that you could introduce kotlin too with Micronaut framework that would be 🔥 🔥 🔥
