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.

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.

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?

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.

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 🔥 🔥 🔥

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 2 жыл бұрын

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:
